Artistic License – Paleontology
aka: Somewhere A Palaeontologist Is Crying
He's got a chauffeur who's a genuine dinosaur.

"Many people (including some scientists!) are confused about what is or isn't a 'dinosaur'. They think that flying pterodactyls or fin-backed Dimetrodon or seagoing plesiosaurs or woolly mammoths are dinosaurs. THEY ARE WRONG!"

Dinosaurs are pretty cool, which is why they are frequently seen in fiction. However, creators do not always prioritize historical or scientific accuracy when dealing with these prehistoric creatures in works. As such, dinosaurs often appear in the wrong time period, along with humans, possess special abilities that they otherwise would never have had, or are treated as pets or friendly characters.

In Real Life many of the most commonly-recognized dinosaurs lived in different habitats, continents or time periods. Some prehistoric creatures, like pterosaurs and plesiosaurs, are technically not even considered dinosaurs. Fortunately, some educational programs attempt to avoid these pitfalls.

Common Inaccuracies In Media

    open/close all folders 

    Paleontology in General 
  • Every 1950s monster film with a Prehistoric Monster. Partly due to Science Marches On, but other times because laziness (especially when a Slurpasaur is involved).
  • On that note, any work claiming that prehistoric reptiles like dinosaurs, pterosaurs and marine reptiles were all "giant lizards". Out of all Mesozoic megafauna, only mosasaurs fit that description; dinosaurs and pterosaurs were as far from being lizards as it was possible to be while still remaining saurian reptiles; in fact lizards (including snakes) are further away on the evolutionary line from dinosaurs than birds (and crocodylians and even turtles) are. The relationships of marine reptiles like ichthyosaurs and plesiosaurs to other reptiles are less certain but they were certainly not lizards.note 
  • Prehistoric animals being shown as much larger than they really were.
  • The act of "shrinkwrapping"; more prevalent in late 1980s-mid 2000s paleoart, shrinkwrapping is basically when artists draw dinosaurs with thin skin that the bones continue to show through, as if their skin has been draped over their bones and there's nothing in between. For comparison, almost no animal in the modern day, including birds and crocodilians (the animals most closely related to dinosaurs) looks like a walking anatomy diagram, so we can be pretty sure that dinosaurs and their neighbors definitely had much more meat on their bones than that. Lately, people have been avoiding this more often.
  • Confusing Paleontology and Archaeology. Paleontology studies remains of past life forms (and their activity). Archaeology studies past human cultures. It doesn't help that paleo and archaeo both mean "ancient".

    Dinosaurs in General 
  • Anything being called a dinosaur that isn't: Pterosaurs such as Pterodactylus, giant sea reptiles such as plesiosaurs, ichthyosaurs and mosasaurs, pre-dinosaur reptiles like Scutosaurus, synapsids such as Dimetrodon (which were not, strictly speaking, even reptiles, but proto-mammals), any modern reptiles (even closely related extinct giant species like Deinosuchus or Megalania), fish or, Darwin forbid, mammals.
  • Anything being called not a dinosaur that is, such as Archaeopteryx or modern birds. Birds being regarded as different from dinosaurs is acceptable for 1980s/1990s works, but not today.
  • Cold-blooded dinosaurs and pterosaurs. Particularly, dinosaurs are often depicted as being unable to function let alone survive in cold climates, when there's evidence that some genera thrived just perfectly in snowy environments (which are often said not to have existed in the Mesozoic era). Even the anatomy of dinosaurs and pterosaurs suggests endothermic lifestyles.
  • Dinosaurs dragging their tails along the ground. An old idea, essentially derived from "Well, crocodiles do it, so they must have". In fact, dinosaurs walked with their tails held rigid. This early misconception led to the academically approved vandalism of several dinosaur skeletons, to the point of even breaking the bones of some to make the tails drag as desired.
    • Dinosaur tails are often shown to be extremely bendy as if they are made of rubber. In real life, dinosaurs had relatively stiff tails, and the bipedal ones even used them for balance. However, some studies have suggested stegosaurids have a higher tail dexterity than previously thought.
  • Dinosaurs only colored grey, green or brown. Another ancient trope derived from the "they were just huge crocodiles" line of reasoning. Crocodilians are grey, green or brown because they are adapted as semi-aquatic ambush predators that depend on camouflage, but in fact, most reptiles today have a wide range of skin colorations and rely heavily on visual communication (having a wider spectrum of color vision than mammals). It is likely that at least some dinosaurs had vibrant colors and patterns. That is not to say no Mesozoic dinosaurs were comparatively drably colored, but brightly-colored representatives probably weren't rare.
  • Dinosaur eggs will often be shown as gigantic, often over six feet tall. In reality larger eggs require thicker shells, but the shell has to stay air-permeable. This limits the size of porous calcium carbonate eggshell for dinosaurs and recently-extinct large birds to about 15 liters in volume and 35 centimeters in diameter — not much bigger than a basketball. No larger eggs have ever been ever found. Eggs from less rigid materials were even smaller. Not to mention that a six-foot egg would also be implausible due to the square/cube law. Funnily enough, the largest dinosaur egg known was laid by a bird that went extinct less than a millenium ago: Madagascar's elephant bird (Aepyornis maximus).
  • Crocodilians as dinosaur descendants. While fairly closely related to true dinosaurs, crocodylomorphs (including extant crocodilians) are in fact a different type of archosaur.
  • Quadrupedal dinosaurs with elephant-like feet.
  • Dinosaurs and pterosaurs with an unnatural number of fingers, toes and/or claws. Archosaurs (the broader group in which dinosaurs, pterosaurs, crocodilians and their relatives belong) by default have four toes on the back feet, and five on the front feet, but only three of which have claws (as seen here); therefore all dinosaurs can only have this amount or less (the other extreme is some advanced titanosaurs, which have no fingers, toes, or claws, their limbs end in fleshy stumps). The most common errors include giving Tyrannosaurus too many fingers, giving herbivores too many claws, and giving pterosaurs too many elongated fingers and too little wing claws.
  • The belief that an ice age killed the dinosaurs. Not only were they dead for 60 million years before the start of the ice age, but the time immediately following the dinosaurs' extinction was actually substantially ''warmer''.
    • For that matter, the belief the ice age (or the end of it) killed ice age animals. In Real Life they adjusted just fine, and almost all of them went extinct not by climate, but by us.
  • The popularity of the film Jurassic Park led to a pan-medial explosion in use of the term "Jurassic" to describe the dinosaurs' time period. Actually, the Jurassic Period only comprised the middle third of the dinosaurs' era (in between the earlier Triassic and later Cretaceous), which in its entirety is called the Mesozoic. This was lampshaded frequently in Michael Crichton's original novel; probably because he didn't want to seem scientifically illiterate but wasn't about to give up such a cool name.

    T. rex 
  • Anytime Tyrannosaurus rex is depicted with three functional fingers or more.
  • Anytime T. rex is spelled "T-rex" or some variation thereof (even "T. Rex" is unacceptable). T. rex is an abbreviation for the scientific name Tyrannosaurus rex, just like E. coli is an abbreviation for Escherichia coli, so the hyphen is not applicable. Scientific names are given with genus capitalized and species not, and are traditionally italicized.
  • Tyrannosaurs as allosaur relatives. Acceptable for pre-1990s works, otherwise horribly wrong.
  • Tyrannosaur arms described as weak. Short, yes. Weak, no.
  • Tyrannosaurs having shallow-rooted teeth, a myth that is often perpetrated by creationists. Unlike the teeth of other theropods, which have roots the same length as the crown, tyrannosaur teeth have roots that are twice the length of the crown. This enables tyrannosaurs to grip onto struggling prey and not have their tooth fall out all the time.
  • It's not quite an inaccuracy (yet), but it's becoming increasingly hard to maintain the position that T. rex didn't have feathers. Most palaeontologists are pretty much settled on the idea but probably won't go public until the evidence is irrefutable.
  • Some Paleontologists have suggested that baby Tyrannosauruses had feathers, but lost them as they grew into adults.

  • Whenever raptors (aka dromaeosaurids) are depicted as scaly, lizard-eyed dragon men with claws. This is Science Marches On for works before the late 1990s, but is inexcusable in the 2000s. While it is debatable whether all coelurosaurs (such as T. rex) were feathered, there is no debate about the raptors. And no, raptors were not just Jurassic Park-style scaly monsters that had been tarred and feathered; they had wings, tail-feathers and feathers surrounding their eyes. If you saw one from a distance, or even with its mouth closed, you would mistake it for a large, predatory bird. Which is exactly what it was.
  • Whenever Velociraptor is depicted as resembling Deinonychus. Deinonychus was a human-sized pack predator that lived in North America, while Velociraptor was a dog-sized lone predator that lived in Mongolia. The confusion is quite deliberate, and can be laid at the feet of two individuals: paleontologist/paleoartist Gregory Paul, who placed them in the same genus (the guy has some fairly idiosyncratic personal views on taxonomy- see "Real Life", below) and Jurassic Park author Michael Crichton, who liked the name Velociraptor so much he didn't care if Paul was literally the only paleontologist on Earth who considered them the same. When creating "Velociraptors" for the first Jurassic Park film, the crew used Deinonychus as a model even as they kept the wrong name in the script, and one of the most enduring public misconceptions about dinosaurs was born.
  • The form of the raptor's hands is often shown wrong. While real raptors had hands which paralleled each other and were wing-like in appearance, most raptors in media have paw-like hands, as shown here.

  • Whenever Stegosaurus is said to have a walnut-sized brain and a second brain in its hip. Also, any depiction of Stegosaurus that has a fat body, a dragging tail, an immobile neck, stubby limbs, and paired plates (excusable if this is seen in older portraits, but not in modern ones).
  • Stegosaurus may be shown with a long sauropod-like neck in some depictions, when it had a short neck in real life (although Miragaia, a long-necked stegosaur, was discovered in 2009).
  • Also, stegosaurs using their plates as armor. While some studies suggest the plates were covered in horn, they are still irregularly placed for protection and keep the animal's sides unprotected. Instead, stegosaurs more likely used the chainmail-like scutes underneath their skin as protection against predators.
    • That wouldn't rule out the possibility of the plates being used for defense. Some scientists (namely Bob Bakker) assumed the horn covering on the plates may have formed into sharp edges and could be used as blades to impede a predator, and the plates may have had some degree of mobility due to being attached to skin and presumably muscle. However, this is debatable.
  • Anytime Stegosaurus is portrayed as being too slow and sluggish to defend itself from predators. Stegosaurs have front legs shorter than their back legs; while this limited their speed, it put the center of gravity in their hips. This enabled stegosaurs to rapidly turn their bodies around, giving them opportunity to strike predators with their tails and keep them away from their weak spots. It helps that Stegosaurus lived alongside swift, fleet-footed predators such as Allosaurus, so maneuverability would have been necessary for its defensive mechanism to be more effective in spite of its size and bulk.

  • Spinosaurus with an allosaur or tyrannosaur-like skull and four-fingered hands. Science Marches On for works from before the late 1980s, but otherwise unacceptable.
  • Also, any spinosaurid that is depicted as an entirely terrestrial predator. All evidence of spinosaurid meals found consists of fish, a young dinosaur, and a fish-eating pterosaur (either caught while fishing or scavenged on the shore). While it is still very likely they could have ambushed other dinosaurs by attacking like a crocodile, killers of sauropods and armored dinosaurs, they were not. As a rule, any theropod with non-serrated teeth is not a sauropod killer, because sauropods require a very specific hunting method. Meanwhile, theropods with crushing jaws and puncturing teeth are more specialized in hunting armored prey.
  • Now some new Spinosaurus fossils make everything pre-August 2014 inaccurate. For reference, it had hilariously short legs and was more aquatic than previously thought. Just how short the legs were, however, is unclear. And several of the post-August 2014 models have proven inaccurate as the assumption it was quadrupedal was proven impossible. However, a 2015 study cast doubt on this, suggesting the short-legged fossils might be either chimeras or from a different species. Any and all known information on Spinosaurus is in flux at the time of this writing, but it seems it most likely was aquatic and had short legs.

  • Egg-stealing Oviraptor. Yes, its name means "egg stealer", and oviraptorosaurs appear to have been omnivorous, but it is unacceptable if eggs are stated to be the main or only source of their diets. The name was chosen by Roy Chapman Andrews, who discovered Oviraptor in 1924 near a nest of eggs, but even he felt it might be misleading. Discoveries of related species since then have pretty much confirmed that those eggs were the Oviraptor's, and she was likely brooding them, not stealing them.
  • Oviraptorosaurs without feathers. They were so heavily feathered that they were essentially indistinguishable from modern birds. They even had beaks.
  • Oviraptor refers only to a single, poorly preserved specimen unearthed by Roy Chapman Andrews in 1924. Subsequently discovered "Oviraptors" have all eventually been placed in separate genera, usually Khaan, Conchoraptor or Citipati. Restorations of "Oviraptor" tend to be based on these other, more well known dinosaurs.

  • The popular name for any type of sauropod is Brontosaurus, or "thunder lizard". However, up until 2015, anyone remotely versed in palaeontology would have told you that the word had as much scientific meaning as the word "unicorn", since Brontosaurus never existed. Rather, the name was given to a misidentified older specimen of an already-named dinosaur. Why and how the word "Brontosaurus" survived is too complicated to explain quickly (in essence, big egos), but regardless, the Rule of Cool knows no statute of limitations, and the Thunder Lizard persisted to this day. And it turned out that was lucky, because in 2015 studies of Brontosaurus skeletons led scientists to conclude that yes, Brontosaurus was its own genus after all, and so the name was brought back from legend into natural history. It's still wrong to use it for all sauropods though.
  • Whenever sauropods are depicted up to their necks in water. This is more commonly seen in older depictions, because paleontologists initially couldn't believe that such huge creatures could exist without being supported in water. However, we now know that sauropods could not breathe in such a situation, and so it is thankfully a slowly dying trope. In fact, studies on the flotation dynamics of sauropods show that they would have floated unsteadily on the water surface rather than walk along the bottom were they to take a dip beyond wading depth.
  • Sauropods chewing their food. They couldn't; they didn't have cheeks or chewing molars. In fact, their long necks were only possible because they didn't need to chew- no chewing means no big jaw muscles, ergo small, light head, ergo long neck.
  • As noted in the comic books section below, the common story about Brontosaurus being just an Apatosaurus reconstructed with Camarasaurus-like head was in fact incorrect even before 2015 revision of Apatosaurus, as the synonymization of Brontosaurus with Apatosaurus was an issue unrelated to the original incorrect restoration of Brontosaurus excelsus. Also, even when both genera were synonymized, their type species Apatosaurus ajax and Apatosaurus/Brontosaurus excelsus were retained as distinct species; just because they were classified in the same genus for a while doesn't mean they were the same animal - just like, say, assigning lions, tigers, jaguars and leopards to the single genus Panthera doesn't mean they are all the same animal.
  • Brachiosaurus with a diplodocid-like body. Brachiosaurids (or at least those for which forelimbs & tails are known) have longer forearms and shorter tails.

  • Theropods with pronated hands. As stated with raptors, their hands paralleled with each other.
  • Depicting carnosaurs as being able to easily kill completely armored dinosaurs such as ankylosaurs, an impossible feat since they have weak bites and cutting teeth. Hence this is why tyrannosaurs are more built for attacking armored prey. These two groups are opposite ends of the specialization spectrum.
  • Mistaking a theropod's antorbital fenestra for its eye socket.
  • Anytime Allosaurus is depicted looking like a three-fingered, downsized Tyrannosaurus (i.e. bulky body, no brow horns).
  • Frilled, venom-spitting Dilophosaurus. The venom was made up by the Jurassic Park novel, the frill by The Film of the Book.
  • Carnotaurus (or any other abelisaurid) with tyrannosaur or allosaur-like arms. They had ridiculously small arms that were actually invisible as they lay flush against the body.
  • Despite popular belief, not all theropods held their spines parallel to the ground. The reason for horizontal stances in theropods is due to the center of gravity being placed in their hips coupled with long hindlegs. Theropods with more upright stances such as therizinosaurs and penguins tend to be top-heavy with shorter hindlegs.
  • The popular depiction of theropods with their teeth sticking out of their jaws is actually, according to recent research, also inaccurate. The very fact that their teeth had enamel indicates theropods had reptile-esque lips covering the teeth; enamel needs to be kept moist to protect the teeth from rotting. The very function of lips is to protect enamel-coated teeth from rotting, so since dinosaurs had enamel-covered teeth...well, they certainly had lips.

  • Ornithischians with lips instead of beaks.
  • Hadrosaurs with visible fingers that may or may not be webbed for swimming. Their fingers were actually embedded underneath skin, bounded into a single thickened "hoof" built for walking on dry land.
  • Styracosaurus with no frill and the long spikes protruding from the nape. And to a lesser extent, it may be depicted with long, Triceratops-like brow horns.
  • Ankylosaurus is often depicted with the wrong body shape, such as resembling a tortoise with a club tail, having big spikes along its sides, or being too thin in width.

  • Plenty of works featuring a pterosaur will use the generic term pterodactyl (usually reserved for the short-tailed pterodactyloid pterosaurs or the genus Pterodactylus) for any kind of pterosaur. Also, said pterosaur is likely to be highly inaccurate, not closely resembling any known species.
  • Pterosaurs launching bipedally. Forgivable if it's Science Marches On, inexcusable otherwise. Also, pterosaurs being bipedal in general.
  • Pterosaurs carrying prey off with their feet, which are often inexplicably transformed into eagle-like talons. Sometimes they would even use them to perch.
  • Much like with raptors, pterosaurs are common victims of nudism in media, lacking pycnofibres or fur-like structures that all pterosaurs were coated with in life.
  • Anytime female Pteranodon are portrayed looking the same as the males, being just as large and having long crests. Real Pteranodon had Bizarre Sexual Dimorphism, with the females being shorter than the males and having short crests or no crest at all.
  • Quetzalcoatlus and any other azhdarchid being vulture-like scavengers or seagull-like fish-eaters in post-2008 works.

    Aquatic reptiles 
  • Plesiosaurs, the long-necked sea reptiles, almost always have bendy necks. In some old books, they are even described as "snake-like". In reality, their necks were relatively stiff and had limited mobility, though they were far from being ramrod-straight.
  • Plesiosaurs or any other marine reptiles coming onto land to lay eggs, as we now know they would die if they tried this and instead gave live birth, probably practising parental care.
  • Mosasaurs with dorsal fringes and no tail flukes.

  • Any medium (including a few documentaries) that suggests that mammals either didn't evolve until after dinosaurs died out or had barely done so when they did. In fact, mammals coexisted with the dinosaurs throughout most of the Mesozoic and may be present in the fossil record as far back as the late Triassic, which would make them almost as old as the dinosaurs.
  • Anytime saber-toothed cats are depicted with long Panthera-like tails, and when they are referred to as "saber-toothed tigers". Primitive saber-toothed cats have proportions similar to non-sabertoothed cats, including shorter canines and long tails. As they become specialized, their fangs grow longer, but so do their necks and front legs, while their hind legs become shorter, giving them a loosely hyena-like profile, and their tail becomes stubby like in a bobcat. Smilodon, the most famous sabertooth cat, is also the last in the series and the one where these features are the most exaggerated. Biomechanical studies have shown that this configuration is better to knock down and hold the prey on the ground before "stabbing" it with the fangs in a meaty, well irrigated area. If Smilodon and co. attacked without securing the prey with their paws first, as they are often seen in fiction, their fragile sabers could break in half.
  • Anytime sabretooth cats are fast and agile. They were actually among the slowest predators in Real Life, relying on ambush and strength, not speed or agility. Sabretooth cats could never chase prey. The one big exception to this is Homotherium, the scimitar cat, but it rarely shows up in media anyways.
  • Smilodon, a strictly American genus, placed in any other continent, and often long after every other sabertooth had gone extinct there.
  • Mammoths always woolly, living in the time of the dinosaurs, or identified as ancestors of modern elephants. There are several species of mammoths, the woolly one (Mammuthus primigenius) being only one of them, and it is possible that the others were as naked as elephants because they lived in warmer climates. Mammoths appeared in the Pliocene, roughly at the same time as hominids, and the wooly mammoth was the last of them, evolving its thick pelt as protection against the cold, from ancestors that were "naked" instead of the other way around; the last ones died out in Wrangel Island, Siberia, around 1700 BC, when the Egyptians were already building pyramids. Asian elephants are more related to mammoths than to African elephants, but mammoths are direct ancestors of neither.
  • Mastodons looking the same as mammoths, despite being shorter and stockier and having a low-domed skull.
  • Mammoths and mastodons are regular victims of Bigger Is Better (to the point "mastodontic" is a synonym of "gigantic" in some languages). There were some truly gigantic mammoths and mastodons (the Columbian mammoth was the third largest land mammal ever, only surpassed by the straight-tusked elephant Palaeoloxodon namadicus and the giant rhino-giraffe Paraceratherium), however the species usually depicted, woolly mammoth and American mastodon, were actually smaller than living elephants. One theory about the American mastodon's demise is that its niche was filled in part by a recent immigrant to the Americas: the moose.
  • Cave bears will usually be portrayed as carnivores in the media, when their dentition and isotope analysis suggest they were herbivores. That said, they probably would eat meat if the opportunity arises.
  • If the gomphothere Platybelodon ever makes an appearance, it will usually be portrayed with a big flappy mouth appendage to match with its famous shovel-like lower jaw. In real life, Platybelodon most likely had a trunk like modern elephants.
  • Anytime Gigantopithecus is portrayed walking upright like a human, mainly in order for it to associate with Bigfoot. While Gigantopithecus is only known from teeth and jawbones, its close relationship with modern apes particularly the orangutan strongly suggests it walked on its knuckles.

  • No, humans did not "evolve from apes". Humans and modern apes share a recent common ancestor from which they diverged. But that even that statement is actually inaccurate; humans have not diverged from apes- humans still are apes. Modern genetic classification defines the family Hominidae as including not only humans but all "great apes" (chimps, orangutans, bonobos and gorillas). Works from before the 80s or so restrict Hominidae to humans and use the now-discredited Pongidae for the other great apes.
  • Despite what certain pictures may tell you, humans did not evolve from chimpanzees either. Recent finds like Ardipithicus have suggested that chimpanzees' quadrupedal posture is in fact a highly derived form, and that the ancestral "missing link" may look more like us than them.
  • There is no archaeological evidence that early man used clubs; that is a figment of modern fantasy, likely derived from mediaeval fictions about wildmen. And while early man definitely sheltered in caves, there is little evidence that they lived in them permanently. Caves are rare, and unlikely to be found on ice age steppeland. Most early men sheltered in huts, much like modern day hunter gatherers.
  • Oh, and contrary to popular belief, humans and dinosaurs did coexist, and in fact still do.

    Anime and Manga 
  • Lampshaded in Magical Shopping Arcade Abenobashi, when the characters land in "Scientifically Inaccurate Prehistoric Abenobashi".
  • Gantz is a partial aversion. Its raptors (actually aliens masquerading as raptor models in a museum) are notably covered in feathers (or maybe fur, but we'll be optimistic). On the other hand, the T. rex shoots fireballs... well, they're aliens.
  • Genesis Climber MOSPEADA subverts this trope: Stick and Ray fall into an underground cavern, where they see a mishmash of various kinds of creatures from different periods, including Dimetrodons, apatosauri, and tyrannosaurs. At first, Ray mentions that something "seems odd" about it, but he can't put his finger on it. Later, he realizes that the dinosaurs are a spattering of dinos from different periods, and the 'cavern' is actually a laboratory where the Inbit are trying to determine the form of life best suited to their "new" planet.
  • Dragon Ball features characters who either have the ability to fly or have a flying device with them. Convenient enough, there are some pteranodons or other prehistoric fliers around. Is someone still unable to fly? No problem, just bring in the T. rex. To be fair, Dragon Ball has a whole lot of other weird stuff so that the pterosaurs and such fit right in. Given that there are also canon dragons wandering around, it's likely it's just a Rule of Cool alternate Earth. Not featured in the manga, in the anime though? There are the same dinosaurs...on Namek. Which could be intended to imply that Kami brought them with him to Earth. Though given the relatively small size of his spaceship, he could only have brought eggs.
    • Another error is Toriyama's design of the Tyrannosaurus—first off, it has what look like horns on its head—now there MIGHT be tiny brow ridges over its eyes, but the design he used is completely off. Secondly, Tyrannosaurus had tiny arms with two fingers—he seemed to have based the arms on Allosaurus. And fourth, it is much too big. Tyrannosaurus would be 12-13 meters long (42-45 feet) and 4 meters high (13 feet), yet are drawn nearly 20-30 meters long and 10 meters tall.
  • One Piece has at least one island with dinosaurs, not that this is out of place given the rest of the world. It's surprisingly more biologically accurate than Dragon Ball Z's dinosaurs.
  • Averted in the Gaiden chapters of Saiyuki; what looks like a rampaging T. rex is proved to be genetically engineered to do just that by the Big Bad.
  • Pickle in Baki the Grappler. Holy heavens. Again, Itagaki Keisuke takes his "almost realistic extreme martial arts manga" and reminds us that it's a "freaking Rule of Cool extreme martial übermensch manga", with Pickle, the Jurassic man. Revived after being found frozen kicking a T. rex in the mouth.
  • You Are Umasou has tyrannosauroids that shift from tripod stance to horizontal stance, the now dubious genus "Titanosaurus", a really bendy-necked elasmosaurid, and a mosasaur with a dorsal fringe, as well as a bit of Anachronism Stew and Misplaced Wildlife. On the other hand, it has feathered maniraptors, hadrosaur nesting colonies, migrating herbivores, pack-hunting tyrannosauroids (a questionable speculation), and snow-roaming dinosaurs.
    • The purple Chilantaisaurus (according to the book and second episode of the animated series) trying to eat Umasou in this scene has a rather interesting case in which it may be hand waved. It is depicted with bull-shaped horns, and yet at the same time no decent skull material of the animal was found yet (although its skull may be no different than other carnosaurs and could have stubby horns).
      • Although because of the horns, some viewers refer to it as a Carnotaurus. Never mind that it has huge arms and claws, which Carnotaurus lacked (and Chilantaisaurus did have).
  • The first Doraemon movie (and its remake) refers to a plesiosaur as "Nobita's dinosaur". Not that the franchise doesn't have other examples (Science Marches On aside).
  • In Cage of Eden, creatures from different points in history, who all lived in very different habitats, live in the island where the characters are marooned at. Justified since it is later revealed that the monsters are but man-made clones.

    Comic Books 
  • Subversion: In Runaways, Gert has a pet genetically engineered dinosaur named Old Lace. Everyone calls her a "raptor" and she does look exactly like a Jurassic Park raptor (Identified as a Velociraptor in the film, but very similar to the the later-discovered Utahraptor). However, as soon as Victor joins the team he points out that it is a Deinonychus, and raptors as depicted in Jurassic Park do not exist. Old Lace is still incorrectly depicted as featherless, but is nonetheless referred to as a real species with a plausible (for time-traveling, Mad Scientist-filled comic books) reason for existing. Also,
    • Played straight: During the Runaways/Young Avengers crossover, the young supers find themselves hit by a mini-blizzard. While the humans quickly shrug it off, Old Lace is rendered practically catatonic, and almost dies, because she's "cold-blooded". However, it was John Ostrom's study of Deinonychus which largely brought on the "Dinosaur Renaissance", which drastically altered the scientific and popular conception of dinosaurs. This renaissance has ultimately resulted in, at the very least, a consensus that some dinosaurs (such as Deinonychus) were closer to modern, warm-blooded birds than to modern, cold-blooded reptiles, physiologically speaking.
    • It's also worth mentioning that Old Lace wasn't "born" in any sense, but was genetically engineered in the 83rd century. Anything odd about her appearance or physiology pales in comparison to her having a telepathic link with Gert.
  • Subverted in a Batman comic. During the Knightfall storyline, Batman and Commissioner Gordon find a dead man inside the skeleton of a dinosaur. Gordon calls the dinosaur a "Brontosaurus" before being corrected as Apatosaurus by a curator, who tells them the story of how the skull of one dinosaur matched the head of another and the other way roundnote , giving its "two-head" clue about the culprit: Two-Face.
  • Though the prehistoric beasts in this Batman comic seem to be robots of some sort, allowing for some errors, there is one completely unforgivable mistake: they misspell the word "dinosaur"!
  • Cadillacs and Dinosaurs... look at the title. If you're expecting accuracy from a series involving dinosaurs coming back several hundred years in the future, why are you even bothering?
  • According to one Chick Tract, the dinosaurs escaped the great flood by getting on the Ark with all the other animals. Unfortunately, the flood destroyed much of the plant life, and the reduced oxygen levels made them sluggish and slow. They were ultimately hunted into extinction by human hunters who considered "dragon meat" to be a delicacy.
  • A lesser-known Spider-Man villain is "Stegron the Dinosaur Man", a ripoff of more stalwart villain The Lizard. The rather-too-conveniently-named Dr. Vincent Stegron steals the lizard formula from Curt Connors and (somehow) infuses it with dinosaur DNA, transforming himself into a half-man, half-Stegosaurus creature... which also has a taste for human flesh and is often depicted with sharp, pointy teeth. Stegron's plots have included:
    • Bringing dinosaurs back to life from their skeletons in museums, despite the fact that dinosaur skeletons in most museums are A) held together with wire, and B) are fibreglass replicas of fossils, which are bone-shaped rocks, or C) even if they're the authentic article, are bone-shaped rocks. Rock contains remarkably little genetic material (i.e., none).
    • Attempting to free the world for dinosaurs by having hundreds of humans in New York conveniently start acting more animalistic and killing each other... using a magic piece of meteorite that he found in a jungle. A particularly glaring error in that story arc (as if the main plot weren't glaring enough) was where a modern lizard is regressed by exposure to the meteor and turns into a Velociraptor. Lizards are not descended from dinosaurs, nor are they closely related to them. If it had been a mutated pigeon, it would have been reasonably accurate, relatively speaking, but for a lizard it's on the same scale as showing a human somehow "regressing" into a water buffalo or a dolphin. Given that Stegron himself is weakened by the cold and speaks in Sssssnake Talk, the writers clearly assumed dinosaurs were typical reptiles.
  • 150,000 years ago, the title character of Rahan (a very well known caveman in France) encounters dinosaurs and sees them as survivors of a very distant past. It's really not as outlandish as some of the other examples on this page.
  • The entire storyline of Dinowars revolves around dinosaurs escaping into space to avoid the ice age, growing into a highly evolved civilization, and then returning to Earth to reclaim what is rightfully theirs.
  • Dr. Dinosaur in Atomic Robo claims that "mammal energies" traveled back in time and granted him super-intelligence while wiping out all the rest of the dinosaurs, and then he built a time machine out of rocks, fronds, and crystals to travel to the present and get revenge. His inaccuracies (such as lack of feathers and presence of a larynx) are largely justified however, when Robo points them out and dismisses Dr. D's story as absurd, assuming he's just a genetic experiment based on a Jurassic Park dinosaur rather than a real one.
  • In one of Hamilton Comics' Mighty Morphin' Power Rangers early issues, Bulk and Skull are seen being Power Rangers, with Skull as Ranger with a Brontosaurus theme. However, Billy points out that it's incorrect and that it would be more scientifically correct "Apatosaurus". Skull, however, thinks it's a hilarious pun and ends up knocking Bulk over in the process.
  • Marville #4, oh boy. For starters, it is set on the "Jurassic Park", not "Period".
  • In Tyrannosaurus Rex , while there's dinosaurs and humans living together, the raptors are coated in feathers.
  • Horácio from Monica's Gang. A vegetarian baby T-Rex. Also, on Monica's Gang we have the Cavern Clan. Just imagine the Flinstones without all the American Sitcom situations to turn into something normal for prehistoric cavemen... like hunting dinosaurs.

  • Walking with Dinosaurs, after its first episode had aired, found itself a target for angry palaeontologists because of one scene that showed a Postosuchus urinating and not excreting its wastes the way its modern relatives, birds and crocodilians do (despite the fact that some archosaurs are, in fact, capable of urinating in addition to excreting uric acid). Later episodes gave more fuel to the debates. While beloved by many, and hailed as a milestone in paleo-documentaries, a number of dino enthusiasts still frown upon its "spectacle over science" approach.
    • The series also had scaly dromaeosaurids, pterosaurs that lacked pycnofibres including an Ornithocheirus increased to the size of a large azhdarchid, a 25-meter Liopleurodon, and an Ornitholestes with a nose horn (though the last one is a result of science marching on) among other inaccuracies. At least none of the dinosaurs breathed fire or tried to eat everything in sight.
    • One of the more controversial additions was giving the Diplodocus an ovipositor, though chiefly because thanks to the computer modelling of their skeletons, the crew had no idea how it could lay eggs from a great height. Thus, they invented the ovipositor (admitting that it was theory in the Making Of video, and since there's no evidence they lacked one...)
    • The sequel, Walking with Beasts, gives early Eocene primate Godinotia an appearance similar to modern Capuchin monkeys - but Godinotia was a member of the Adapidae, a prosimian family more related to lemurs and bushbabies, and like them, it most likely had a hairy face, hands and feet, and a "dog-like" snout. Megafauna experts also criticized the documentary for giving credence to Fariña & Blanco's fringe theory that Megatherium complimented its vegetarian diet with carrion and prey stolen from carnivores. The theory has the arguments "it is not impossible" and "it would be really cool if these claws were used to stab sabertooth cats" going for it, and pretty much everything that is known about ground sloths against. Other errors include Basilosaurus being an open-sea hunter, sabretooths chasing prey and living in lion-like prides, and in an extreme case of Science Marches On, depicting the herbivorous Gastornis as a hunter.
    • WWB is also guilty of Prop Recycling their bear-dog model from Oligocene-set "Land of Giants" as a miacid carnivoran in Eocene-set "New Dawn" (miacids were weasel-like, arboreal and plantigrade, unlike the show's bear-dog which is terrestrial, cursorial and acts like a dog); and their Pliocene sabertooth Dinofelis model from "Next of Kin" as a Pleistocene cave lion in "Mammoth Journey". In the second case, they bothered to give the animal another coat and a big cat-like long tail (though one promotional image still shows it with the short sabertooth cat-like tail), but the sabertooth proportions are still evident in its longer forelimbs, flat head and protruding saberteeth. Compare this actual restoration of a cave lion in BBC's later series Ice Age Giants.
    • The second sequel, Walking With Monsters, presents arthropods as having no brain and incapable of intelligence (some arthropods are actually among the smartest of animals) the jawless fish Cephalaspis as ancestral to land vertebrates (it belongs to the wrong branch of fish), diapsid Petrolacosaurus as ancestral to synapsid Edaphosaurus (one is in the line to modern reptiles and birds and the other is more related to mammals), Dimetrodon as ancestral to gorgonopsian Inostrancevia (too derived for that) and Diictodon as ancestral to Lystrosaurus (the second appeared before the first). Also, the eggs of Petrolacosaurus and Dimetrodon are depicted as mineralized, but this is an exclusive feature of archosaurs (crocodiles, dinosaurs, birds); other tetrapods (such as lizards and monotreme mammals like the platypus) lie soft, almost elastic eggs.
  • Jurassic Fight Club, the Poor Man's Walking with Dinosaurs on The History Channel. Hosted by "Dinosaur" George Blasing, this does not involve lines like "you are not your fucking primitive feathers" or a Tyrannosaurus trying to punch itself in the face with those stubby little arms. It's just a bit of paleontological pretext to some Cretaceous predators having dust-ups. Let's take a look at the errors:
    • They have the same naked generic "raptor" dromaeosaurs and improbably fierce dinosaurs that have been hanging around since Jurassic Park, plus the weird, unfounded suppositions about how dinosaurs behaved ("raptors" coordinated their hunts by using hand signals? Okay, then...) from Walking with Dinosaurs without quite the special effects quality of either.
    • Juvenile T. rex did NOT look like exact miniature copies of the adults and, in fact, looked more like Nanotyrannus. Oh, and also, there is a debate among paleontologists as to whether or not Nanotyrannus was even a separate genus of dinosaur at all or if the specimens found were really that of juvenile T. rex skeletons, with evidence leaning toward the latter. However, for all its other flaws, the series does dedicate a portion of that episode to the controversy over whether or not Nanotyrannus was its own genus.
      • It's interesting that in the narration they did say that juvenile T. rex were not shaped like miniature adults and were in fact physically very similar to Nanotyrannus. But then in the actual animation the juvenile T. rex were copies of the adult models and shrunk down. They could've at least used the Nanotyrannus model and changed the color scheme.
    • There is some anachronism in the series as well. Episode 8, "Raptor's Last Stand", has a flock of pterosaurs standing on the back of a Gastonia. Only problem, they were miniature azdarchid pterosaurs, pterosaurs who in some cases were bigger than a giraffe, and were at least condor-sized. There is the little fact that azdarchid pterosaurs didn't appear until the Late Cretaceous, which began around 100 MYA, while Gastonia and Utahraptor lived a full twenty-five million years earlier. That is the equivalent of a entelodont being labelled a contemporary of man.
    • Also, Pachyrhinosaurus is portrayed with a horn on its nose. What's the problem, you might ask? It got famous for lacking this feature.
    • Majungasaurus, just Majungasaurus. Not only did the show not get the memo that the dinosaur had gotten a name change from Majungatholus to Majungasaurus, but the host goes on to state that Majungasaurus's ugly appearance was caused by inbreeding, leading to horrible mutations. Apparently "Dinosaur George" doesn't know that, despite its lumpy skull and proportionately short legs, Majungasaurus was one of the prettier members of the abelisaur family, and in fact other species like Carnotaurus and Rugops were a lot more ugly looking.
      • Or perhaps "Dinosaur George" just happens to have weird ideas about dinosaur beauty?
    • They fail animal behavior pretty hard, too. The Nanotyrannus episode, for example—large predators kill competing species and their young all the time. Just look at the interactions between lions, leopards, spotted hyenas, and cheetahs on the African savannah. It isn't even unheard of for a predator to continue to maul the carcass of a threat or rival long after such attacks are necessary. But the mother tyrannosaur tearing up the remains of the Nanotyrannus and scattering them around as a warning to other predators? That's probably giving them credit for a little too sophisticated of thinking.
      • If anything, scattering blood, guts, and bone around the area would have drawn other predators closer. Fail.
      • The animal behavior issue also comes up in the episode where a "raptor" pack takes on an Edmontosaurus as well. The narrator repeatedly says that the dromaeosaurs normally wouldn't take on such large prey, but they're driven to protect their territory. That's not quite how territoriality works. Have you ever heard of a family of foxes attacking a moose to drive it out of their territory? Carnivores defend their territories from other members of the same species. They don't care about keeping every living thing out of their space. After all, what would they eat if they did that? If it was near a den/young or if they were desperately hungry that would be one thing, but it makes no sense for them to keep attacking such a formidable animal because it's in their territory.
  • Monsters Resurrected, a Discovery Channel series, is easily one of the most inaccurate documentaries on prehistoric animals ever made, particularly in regards to the Spinosaurus episode. If anyone thought Jurassic Park III did a misleading job at portraying the creature, it was nothing compared to this episode. Essentially, the Spinosaurus is portrayed as the ultimate predator of all time, able to effortlessly kill any other predator that lived in its time and region. In short, it is depicted as devouring a Rugops with one bite, killing a Carcharodontosaurus by slashing it across the face with its claws and effortlessly tearing apart the giant crocodylomorph Sarcosuchus (which was extinct by that time to boot). And that isn't all, its size is practically Godzilla-portioned, as it is able to pick up a 30ft long Rugops in its mouth and the thing appears to be no bigger than its head. Spinosaurus didn't grow much larger than 60ft, meaning the one depicted in the episode would have been close to 300ft. The episode also seems to take a lot of facts that we know about the animal out of context, seemingly with no other reason than to turn Spinosaurus into some kind of prehistoric Villain.
    • They also got away with flexible-necked plesiosaurs and naked raptors in other episodes.
    • A full list of errors in the program would be the size of the show's Spinosaurus.
    • One notable error in the Varanus priscus/Megalania episode was the fact that the aboriginals depicted in the episode had European skin colour. This does not need any explaining at all. That episode also gets extra fail points for actually underrating its main species as stupid, just because it was a reptile (its very close relatives are as smart as any equivalent mammal and it would have been as well), plus making it only one-quarter its actual size.
  • Clash of the Dinosaurs showed obvious signs of this trope, like making Quetzalcoatlus a scaly, flying reptile hunting eagle-style from the air instead of the fur-covered, terrestrial pterosaur it was, and having dinosaurs defending themselves with sonic weapons. It really caused grief to one of the paleontologists they interviewed by QUOTE MINING him.
  • Animal Armageddon, while not a bad program when it comes to explaining geological science, had some of the worst and most ugly-looking CGI dinosaur recreations imaginable, almost all of which suffer from anatomical inaccuracies.
    • The episode on the Toba eruption ("Ice and Fire") picks its fauna at random. It shows the giant rhinoceros Elasmotherium living in herds in the Sumatran jungle and being hunted by lion-sized "Sumatran leopards" that are fast as cheetahs, a description that better suits the giant cheetah, Acinonyx pardinensis; however neither lived in Sumatra or a jungle environment, but on the Eurasian plains,note  A. pardinensis was also extinct by this time, and likely fed on deer and antelopes rather than on the giant Elasmotherium, which was probably solitary and had no real predators. Gigantopithecus, also extinct at the time, is portrayed fending off black "pumas" in what is now Vietnam, that are described as its main predator. There is no evidence that pumas ever existed in SE Asia, or that Gigantopithecus had any predators at all.
  • ITV's March of the Dinosaurs had dinosaur-freaks up in arms with just its preview images. While feathered tyrannosaurs and arctic mosasaurs might have looked awesome, the not properly feathered, small-winged (they should have actual wings with wing feathers) Troodons worked as horrible eye-sores for them. Indeed, we live in a time in which popular dinosaur restorations are forced to take a middle route between being too feathered for the general public's comfort, but not feathered enough to please dino-maniacs.
    • This is without mentioning the Quetzalcoatlus; its anatomy is messed up beyond repair, to the point that it's bipedal and lacks its wing claws.
  • While not specifically about prehistoric life, The Most Extreme messed up big in episode 65, Awesome Ancestors. Just what did they screw up on, you may ask? Tyrannosaurus rex was more closely related to your standard chicken than it was to the Komodo dragon. A more appropriate ancestor for the Komodo dragon would be the 50-foot long mosasaur, a predatory sea-going lizard that lived around the same time as the last dinosaurs and are thought to be distantly related to modern-day monitor lizards.
    • T. rex had many traits similar to those modern-day birds and was most-likely warm blooded, unlike the cold-blooded Komodo dragon which has more standard reptilian traits. Oops.
      • Megalania would work just as well, being an actual giant lizard related to the Komodo dragon.
  • The Dinomorphosis episode of Naked Science. Even disregarding that woefully outdated and unrealistic reconstruction of Oviraptor, it had actual scientists lamenting over the fact that the "poor T. rex" may have been feathered in real life, as if this somehow made it less badass. Um, nice job trying to forward the latest findings to the audience there, by explicitly saying how lame the new dinosaur image is. Surely, its immensely powerful bone-crunching bite and title as the baddest North American predator around at the time mean absolutely nothing now that we know it had fuzz somewhere on its body.
  • Paleoworld had an episode on prehistoric rhinoceroses that used an animatronic Triceratops. (To be fair, the palaeontological advisors did say that Triceratops was not, in any way, very closely related to any rhinoceros. The higher-ups did it anyways because Triceratops looked like a rhino slightly, and they had the footage, so they put it in the episode. So it's more an example of Executive Meddling.) Another episode contained the implication that Carnotaurus was older than Allosaurus.
  • There is an episode of Ancient Aliens that claims that dinosaurs survived into historical times, and were nuked by extraterrestrials. Not only does all shown evidence look fake or exaggerated, but they have religious archaeologists and come up with all sorts of strange ideas, including that aliens used genetic engineering to reintroduce animals like coelocanths and crocodilians because they existed in the Mesozoic and somehow had to appear in the present, and that dinosaur bones are painted with lead because they are extremely radioactive!
    • There was actually a fringe theory in the 1970s that the Cretaceous extinction event was a nuclear holocaust by a yet-undiscovered sapient theropod (so, Ultra Terrestrials rather than aliens). There are a few resemblances between the conditions observed at the end of the era and the effects of nuclear fallout, and any evidence of a civilization would have vanished in 66 million years. The theory, however, had more to do with Cold War anxiety than scientific plausibility.
  • Although not a bad program for explaining science, National Geographic's Evolutions somehow had a pair of Monolophosaurus kill a Diplodocus. Misplaced Wildlife and Anachronism Stew aside, the rationale for this basically came down to "Diplodocus was big, it was slow, and its teeth were ill-suited for combat". Try telling that to pretty much any large herbivore alive today. On the other hand, the Velociraptor has feathers with wings, and the Archaeopteryx model that briefly appears has long leg feathers.
  • Life After Dinosaurs somehow managed to produce a CGI model of Smilodon, in 2012, that has inaccuracies not seen in paleoart since the 19th century. The show's animal is built like a modern big cat, its lower incissors are shorter in the middle forming a "V" for some reason, and it walks with all its claws extended at all times. Being a sabertooth cat (one too big to climb too), Smilodon obviously retracted its claws when it wasn't fighting.
  • The French documentary L'odyssée de l'espèce shows the famed Lucy and other australopithecines struggling to walk upright. There is no evidence to back this beyond the documentary makers' preconceived opinion that because australopithecines were "primitive" compared to us, their locomotion should look difficult and imperfect. Every study on australopithecine fossils has shown, however, that while their legs were proportionally shorter than ours, they were entirely prepared to walk upright, and that their gait wouldn't be noticeably different from our own (the more primitive hominid Ardipithecus, who had less human and more simian-looking feet, might have been different). Paleoartist Mauricio Antón compared the images of mo-cap actors struggling to walk "imperfectly" in the documentary's making off to the zombie dancers in Michael Jackson's music video, Thriller.
    • Adding insult to injury, Lucy's species Australopithecus afarensis is shown to walk even worse than, and be outcompeted as a result by, the species Australopithecus anamensis. In reality, A. anamensis lived before A. afarensis and was the more primitive of the two. In fact, A. anamensis is likely the direct ancestor of A. afarensis.
    • Unlike Australopithecus and previous hominids Sahelanthropus and Orrorin, Homo habilis was played by actors wearing prosthetics rather than by Serkis Folk, and they walked perfectly. In real life H. habilis had the same "simian" long arms and short legs of Australopithecus. Any of them would have been as much a good or poor upright walker as the other.
  • Everything You Didn't Know About Animals (which isn't bad with facts about modern animals) confused Smilodon with the metatherian Thylacosmilus and claimed that the Italian Miocene owl Tyto gigantea preyed on people (which were limited to Africa at the time).

    Eastern Animation 
  • There is a Soviet cartoon called Mother For Little Mammoth. It is about the eponymous mammoth who thawed out in our age searching for his mom. He finds one, an elephant in Africa. A truly happy ending, except one of the traits by which she accepts him is the fact that, like her, he has big ears — and the mammoth is pictured with such. Now, an elephant's big ears are heat sinks — mammoths didn't need nor have them.
    • Big ears on mammoths might not be out of the question, particularly if it's a species that lived in warmer climates. The problem is that the mammoth in question is a woolly mammoth, which definitely did not have big ears.

    Fan Works 
  • The World of the Creatures plays with the trope throughout. The story takes place in the mind of someone obsessed with paleontology. As such, dinosaurs show up frequently. In many cases both accurate dinosaurs - such as a fully-feathered Utahraptor - and inaccurate ones like the featherless raptors of Jurassic Park appear side by side.

    Films — Animated 
  • The "Rite of Spring" sequence in Fantasia may be one of the Trope Makers here. It shows off a random cross-section of prehistoric life in the space of a few minutes. In part, it's Science Marches On: it is proudly announced that this section is Based on a True Story.
    • 25 years later, the Disney Imagineers created a Primeval World diorama for the 1964-1965 New York World's Fair, with many of the individual scenes apparently inspired by Fantasia. This diorama, which is currently installed at Disneyland in California, is a slight improvement on the film — the first scene shows dimetrodons in a Coal Age forest of giant horsetails (and giant dragonflies), and then moves to a Jurassic swamp with some generic sauropods, followed by scenes featuring Pteranodon, Triceratops, and Struthiomimus (all Late Cretaceous, although the precise ages differ somewhat). So far, so good; the sauropods look ridiculous and should not be munching water weeds in a swamp, but that can be put down to a combination of 1960's paleontological ignorance and artistic license. But then the final scene depicts a Stegosaurus battling some large carnosaur beside a violent lava flow. If the carnosaur is supposed to be a T. rex, as the narrator usually states, why does it have three fingers per hand, and what is the stego doing in the Cretaceous? You could ignore the narrator and assume that the setting has reverted back to the Jurassic for some reason, and the stego is fighting an Allosaurus... but that doesn't explain why stego has five tail spikes on its thagomizer. Sigh.
      • Walt Disney has stated that the carnivorous dinosaur fighting the Stegosaurus is a Tyrannosaurus. Paleontologists told him that T. rex should only have two fingers, but he declined because he thought people wouldn't recognize a Tyrannosaurus with only two fingers.
  • Extremely evident in Disney's Dinosaur, which had dinosaurs from the Jurassic and the Triassic period interacting with Cretaceous-period dinosaurs. In an effort to show that the writers had done some research, they included a Carnotaurus as the main predator — too bad Carnotaurus lived in South America, while all the other dinosaurs were North American species, and furthermore were several times bigger than in reality. There was a Hand Wave when one character was astounded that the carnotaurs had come "this far North" (which doesn't work, since North and South America was separated by a sea at the time), and the Brachiosaur character was explicitly stated to be the only one of her species left. The main character had also been adopted by lemurs, when most mammals were superficially rat-like then. Also, iguanadons originally had their beaks, but Jeffrey Eisner insisted that the dinos be able to talk, so the beaks were replaced by speech-friendly lips.
  • When consulting paleontologists for Ice Age, the writers were reluctant about putting dodos in. They were told "Whatever, just please, no dinosaurs". Though there was a dinosaur in the film, it was frozen in ice, presumably for millions of years. Let's just hope those same paleontologists haven't seen the third installment...
    • Somebody should have told them that Dodos (and for that matter, all the other birds) are dinosaurs...
  • The Land Before Time. Pity the professors of geology and paleontology who have small children at home, because all the errors in these films will indeed make a paleontologist weep. The original movie can be considered relatively accurate for its time (Anachronism Stew aside, and then only for stegosaurs and pelycosaurs), at least as far as dinosaur depictions in popular media are concerned. But the sequels and TV series zig-zag this trope several times, with notable aversions including the anatomically correct (if improbably large) Liopleurodon from "Journey to Big Water" and Ruby the Oviraptor having feathers.
  • Rex from Toy Story is a green plastic Tyrannosaurus rex with three fingers on each hand instead of two like in real life. Justified, since he's a toy T. rex, which is often portrayed incorrectly, and a cheap knock-off from a small company that went out of business and was bought by Mattel in a Thanksgiving auction, at that.
  • We're Back! A Dinosaur's Story features Anatosaurus, which is indeed a bona fide member of the duckbill group. Sadly, the duckbill is shown with a long bony crest on the back of its head more reminiscent of a Saurolophus or Parasaurolophus than a smooth-headed "Anatosaurus"... The Pteranodon is even worse, having a long tail and being bipedal. And she is mistaken for a bat, which might be a lampshading of how ridiculously bat-like her wings are.
  • Dino Time 3D is not meant to be a biologically accurate film, but they did have one redeeming trait: a feathered baby Tyrannosaurus.
  • The Good Dinosaur features dinosaurs together (such as Apatosaurus and Tyrannosaurus) that lived in different eras. The official explanation is that the movie is an Alternate Timeline of a almost-modern day where dinosaurs did not become extinct after a meteor strike 65 million years ago, but some of the dinosaurs depicted had gone extinct a hundred million years before that event.
  • The animators of The Missing Link (AKA B.C. Rock) evidently chose to completely forgo realism in favor of Rule of Funny. Aside from having humans, dinosaurs and prehistoric mammals coexisting, many of the animals are completely made up. Examples include a single-legged being with a trunk, an underwater elephant that lives in a giant shell and at least two humanoid (but non-human) species: the bottom-heavy "No-Lobes" and a tribe of feral Catgirls.

    Films — Live-Action 
  • Parodied in Caveman. Yes, there are cavemen and dinosaurs in the same film, but few scientists would be able to cry for the laughter. Not only does the movie occur "One Zillion Years Ago", but the main dinosaur seen in the movie is a geriatric T. rex that is alternately denied delectable cavewoman meat, stoned off a burning cannabis plant, and fondled and then smacked where it counts by a blind caveman (note that dinosaurs would have their goolies internal, like everything other than mammals does). The other prehistoric creatures include a pteranodon which has its (10ft long! Ouch!) egg stolen and a stop-motion creature resembling some outlandish Slurpasaur.
  • The original King Kong (1933) and its sequel The Son Of Kong feature many prehistoric animals portrayed as overly aggressive carnivores even if they were herbivorous (Apatosaurus, Styracosaurus, and Stegosaurus, to name a few) and one dramatically oversized pterodactyl to help ruin the image of its eponymous, misunderstood ape.
  • Peter Jackson's remake does the same, with the justification that they have been evolving the whole time and it's pure coincidence they look like popular depictions (but some don't, like the Ferrucutus or the Atercurisaurus). They even came out with a tie-in book exploring the unique fauna of the island — which shows the usual errors like the lack of any plumage on any non-avian dinosaurs - even the birds seem to have as little feathers as possible, pronated hands, live birth etc.; as well as many non-dinosaurian biological impossibilities.
  • Subverted with the Godzilla films in that Toho doesn't even try to pretend to be remotely accurate in any way whatsoever.
    • A case can however be made for the first movie, Gojira, which was to be taken seriously. In it, a paleontologist deduces that the titular monster hails form the Jurassic period by finding a trilobite in one of its footprints. Trilobites died out about 50 million years before that period, but this can be hand waved, given that in the movie's universe, prehistoric creatures still exist in modern times. The true error is that the supposed paleontologist places the Jurassic at 2 million years BC. He's off by about 150 million years. Even in 1954, scientists knew a lot better than this. And yes, there was serious paleontology done in Japan.
    • There is one thing Toho got right: Godzilla (as well as his pre-mutated form Godzillasaurus) is often portrayed with his hands facing inwards, just like a real theropod.
  • Somewhere a paleoanthropologist and an archaeologist are crying: in The X-Files: Fight the Future movie, we see a Neanderthal in North Texas 60,000 years ago. Not only were there no Neanderthals in the Western Hemisphere ever, there is strong dispute about whether there were hominids of any kind in the Western Hemisphere 60,000 years ago. Maybe they were all abducted by aliens?
  • 10,000 BC: An Androcles' Lion type situation with a Smilodon. "Terror Birds" about 2 million years after they went extinct.note  And woolly mammoths being used to move bricks to build the Pyramids in Ancient Egypt. Rule of Cool taken to the very limit.
    • Neither Smilodon (clearly the species/genus being represented on filmnote ) nor "Terror Birds" ever lived in Africa. Both animals were restricted to North and South America. Then again, given how the characters seem to WALK from South America to Africa...
      • In the beginning when hunting the mammoths; they refer to the head of the herd as the "Lead Bull", meaning that the leader of the herd is male. All indications are that mammoths behaved very similarly to modern elephants... who are led by matriarch females. The males travel separately from the herd.
      • It would seem that sometimes Science Marches Backwards. A partial specimen of what appears to be a small relative of the terror birds was recently discovered in North Africa. So that one "mistake" might not be as wrong as it seemed at the time... if we ignore that it lived several million years before the beginning of mankind anyway.
  • The Sci-Fi Channel Original Movie (which should give you a hint as to its quality) 100 Million BC has the humans unable to detect the rampaging Giganotosaurus through a heat sensor because "dinosaurs are ectothermal" (sic). Even if Giganotosaurus was an ectotherm, its body temperature and metabolism by sheer virtue of its size would be like that of an endotherm (due to a little thing called inertial homeothermy). It would have showed up on a thermal sensor.
    • Also, the heroes visit South America 70 million years ago (despite the fact it's 100 Million BC...) and Gigantosaurus became extinct around 90 million years ago.
    • Nevermind an ectothermic animal is one that can't produce its own internal heat. It doesn't mean it can't accumulate heat from its environment and be warm as a result. As any introductory book to Biology would say, a lizard that has been basking under the sun for hours will be warmer than a mouse.
  • Jurassic Park: film-only issues include the Dilophosaurus being too small and having a retractable frill (for the practical purpose of distinguishing them from the Velociraptors), and repeatedly misspelling the dinosaurs' names... though technically, they're "genetically-engineered" based on reptile and amphibian DNA; their resemblance to real dinosaurs is purely superficial.
    • The first time we see Grant and Sattler is at a dig in Montana uncovering a Velociraptor skeleton, which never existed anywhere near there. What's more, the skeleton is still assembled correctly, even though most fossils are found with the bones scattered all over the place.
  • In Jurassic Park III, Pteranodon (literally "toothless wing") are given tooth-filled beaks, grasping feet, and the ability to pick up a grown man that had to outweigh them by a good fifty pounds at least. Meanwhile, the raptors are "smarter than primates".
    • While the Spinosaurus was indeed bigger than the T. rex, it would never have been able to take one on in a fight. A rex's heavy jaws and thick teeth were built for crushing bone while a Spinosaurus's thin jaws and teeth were better suited for hunting fish. The first time the rex clamped down on its slim bony neck should have crippled it, if not outright decapitated it.
    • Alan Grant refers to the dinosaurs made by InGen as "Genetically engineered theme park mutants", pointing out that InGen deliberately made their dinosaurs to be more awesome than real dinosaurs just for the crowds, and that anything learnt about real dinosaurs from them would be distorted.
  • Super Mario Bros. The Movie hits a few common dinosaur-related errors, though the filmmakers seemed to be going for Rule of Cool. These include:
    • The meteorite that caused the extinction of the dinosaurs is implied to have done so immediately, while also hitting Earth where present-day New York City is located. To be fair, this was before the actual location of the meteorite's impact and its affect were commonly known or proven.
    • The humanoid dinosaurs in the parallel world, such as Koopa and Lena, display qualities and behaviors more typical of modern lizards, such as tongue-flicking and prehensile tongue-use. However, it is implied that the dino-humans developed these traits over time as they became more like modern reptiles, while the prehensile tongue-use was taken from the games (Yoshi).
  • Pioneering filmmaker D.W. Griffith's 1914 film Brute Force shows a group of cavemen attacked by a dinosaur.
  • A throw-away line of dialogue from Puma Man:
    So dinosaurs became extinct because they no longer knew how to love each other?
  • In Batman & Robin, Mr. Freeze knows absolute zero about what killed the dinosaurs.
    Freeze: The Ice Age!
Ironically, as That Other Wiki points out, the climate in the epochs immediately following the K-T extinction was substantially warmer.
  • The main villain of Devil Fish is a mutated Dunkleosteus/octopus hybrid. In the movie, ignoring the obvious issues, Dunkleosteus is described as a prehistoric shark. Real Dunkleosteus were members of a now-extinct family, the Anthrodira, which left no surviving descendants and was only distantly related to sharks. They also claimed that the pliosaur Kronosaurus was a shark that lived during the "Cetaceous period" [sic], which was about 200 years ago (the 1770s?). Another fish that they describe as a prehistoric shark is a very modern, harmless basking shark.
  • The 1960 movie Dinosaurus! featured the discovery and unintentional revival of a Brontosaurus, a Tyrannosaurus rex, and a caveman. Obviously these are the most well-known pre-historic creatures today, but lived tens of millions of years apart.
  • The page image for Prehistoric Monster, taken from One Million Years B.C., depicts a kangaroo-stance Allosaurus that stands only slightly taller than the humans in the picture. In real life, even the smallest Allosaurus would stand about a foot and a half taller than an average-sized human being. (Also, assuming the title of the film is accurate, dinosaurs would have gone extinct some 64,000,000 years ago.)
  • In Pacific Rim, the Kaiju are stated to be so big that they require two brains "like a dinosaur". While some early paleontologists thought some dinosaurs (particularly the stegosaurs and sauropods) had two brains, virtually no paleontologist believes it today.
    • This is a special case though, since it's just a line spoken by a scientist (but not a paleontologist) to a crime lord and thus it's possible that neither of them know that it's incorrect. The film never actually shows a two-brained dinosaur. Though it does imply that either the Kaiju killed the dinosaurs, or were the dinosaurs, and Kaiju do have two brains in the movie.
  • In the comedy Bringing Up Baby, one of the main subplots involves paleontologist Cary Grant retrieving a missing dinosaur bone with the help of Manic Pixie Dream Girl Katherine Hepburn. The bone in question is described as an "Intercostal clavicle". There is no such thing as an "intercostal clavical". Intercostal means "between the ribs" and the clavicle is a collar bone.
    • The dinosaur in question is called a Brontosaurus. Even at the time the film was made, the scientific community would have called it Apatosaurus.

  • Eric Garcia's Anonymous Rex series of novels is just odd but a few things stand out. The trilogy's premise is that talking animals walk among us disguised as humans, and that most of these are the few species of dinosaurs who survived the mass extinction at the end of the Cretaceous. They exist in the present day in exactly the forms they had on the other side of the K-T Boundary (though implicitly smaller or larger as the case may be). His protagonist is a Velociraptor — a Jurassic Park-style nekkid velociraptor with external ears — private eye. The other main characters tend to be obvious dinosaurs like tyrannosaurs and hadrosaurs. Garcia's only research (and he openly admits this) is to have read and watched Jurassic Park a lot, but there's so much Rule of Funny going on ("Manimal: the Musical!") that the lack of research actually serves to make the series funnier. (And did we mention the — ahem — interspecies romances?)
  • The Megamorphs book In the Time of Dinosaurs tried pretty hard to avoid this, with the only real anachronism given a Hand Wave (Tobias: "Who are you gonna believe, some scientist with a bunch of bones, or someone who was actually there?!") in the epilogue. (It was actually a case of Shown Their Work meets Rule of Cool - K.A. Applegate was doing her research, found out that certain dinos weren't around at the time of the extinction, then came up with the Hand Wave so she could get away with keeping them around.) Then again, it starts out with a nuclear explosion causing Time Travel and also had crab-aliens and ant-aliens in a minor war over the Earth at the same time, so...
  • The Jurassic Park novel actually doesn't commit this crime too much, as it tries to generally depict accepted theories on dinosaur behavior, and explains everything in a way that actually makes a lot of sense logically. The mix-and-match assembly of species from different periods is attributed to the fact that the geneticists who made the dinosaurs didn't care, and John Hammond, the guy in charge, was just relying on the Rule of Cool. The name of the park was chosen to appeal to investors, and to customers (had it opened for business), and not with any regard for accuracy. The whole "can't see you if you don't move" is actually attributed to all the dinos, not just the T. rex, as they had to fill in genetic gaps with the DNA of similar modern day reptiles and amphibians, many of which actually do have motion-based vision. The Velociraptors, though, are a lot closer in dimension, even in the books, to really large Deinonychuses. Partially justified in that Crichton was relying on a classification that called Deinonychus a kind of Velociraptor; but this classification was the sole opinion of the famous paleoartist Greg Paul, in his widely-read book, not backed up by paleontologists.
    • It uses this trope when the dinosaurs are in any way interested in the humans. The idea of a Tyrannosaurus chasing a human for food is like you chasing a mouse for the same reason. The novel does Hand Wave the idea for the Velociraptors, though. As Malcolm mentions, somewhere along the line, they must have realized that humans are easy prey — much as tigers tend to become man-eaters if they kill a human while starving. Easier to kill, that is, as long as they aren't the main characters.
      • Possibly justified if the dinos are smarter than the humans gave them credit for, and have learned to associate the appearance and scent of human keepers with their daily delivery of food. Might T. rex have kept chasing the little squealing scampering things because she was used to them depositing a few hundred pounds of prime rib in front of her?
    • Mentioned in Stephen Jay Gould's Dinosaur in a Haystack:
      Gould: Why did you put a Cretaceous dinosaur on the cover of Jurassic Park?
      Crichton: Oh my god, I never thought of that. We were just playing around with different cover designs and this was the one that looked best.
    • The sequel lampshades it with a character who points out several of the problems with the original, and comes up with a few guesses on what else could have caused things like the T. rex acting like it couldn't see them.
      • Then again the sequel also has its own share of bizarre mistakes and speculation, most memorably a scene featuring a pair of Carnotaurus who can change the color of their skin to such a detailed degree that they turn virtually invisible when standing still. While there are real creatures that can change colors, something that large being able to stand out in the open and just vanish to the naked eye is absurd. The notion that a large theropod evolved a natural camouflage system on par with the Predator's cloaking device is even more outlandish than Dilophosaurus having a frill and spitting venom, since at least the latter is based on traits of real animals.
    • All of the problems or errors in Jurassic Park are lampshaded by the characters. They repeatedly criticize John Hammond for his negligence and lack of attention to detail. Henry Wu explicitly points out that the dinosaurs are not authentic, but rather scientific mishmashes of DNA that approximate dinosaurs for the consumption of tourists. As with Hammond, Wu is also depicted as being disinterested in the details of his work, and with deadly results.
    • Not to mention that many of the species of dinosaur lived millions of years apart even from each other, never even having the chance to interact in the past — which just messes things up more in the park since they'd lack millenia-old instincts on how to interact with them.
  • Steven Baxter's book Evolution. While most of the time he gets the science right, and the speculative leaps he takes are somewhat within the bounds of plausibility, a few examples must be mentioned. The story about primates coming to North America has some anachronism and Misplaced Wildlife in it. Not only does it have indricotherid rhinos (native only to Asia), camels (who were only found in North America at this time), and such, it has gastornid birds inhabiting Oligocene-Miocene Africa...yes, even after these animals were supposed to have died out in the middle Eocene. The story involving Purgatorius has some flaws too. While Baxter does get it right by cloaking his troodonts in feathers, he leaves them off his dromaeosaurs. To add insult to injury, he makes the raptors cold-blooded, despite the fact that raptors are the very dinosaurs which ignited the cold blood, warm blood debate. In fact, even paleontologists who doubt endothermy in ornithischians and sauropods don't deny that raptors were most likely endothermic. And then there are the Giganotosaurus and Suchomimus in North America, many millions of years late and/or on the wrong continent; though this could be handwaved as them being different, not-yet-discovered species from those genera. In the story about the sapient Ornitholestes, he mentions that the only evidence humans had of these species is the disappearance of "the giant sauropods" in the Late Jurassic, since the sapient species bones and technology are too fragile to preserve. Now it's true that Diplodocus, the only species depicted in the story, did become extinct at the end of the Jurassic; but there were other giants, such as Sauroposeidon and Argentinosaurus, right through the Cretaceous.
  • Both used and lovingly averted in James Gurney's Dinotopia. Okay, yes, every prehistoric creature from Opabinia to woolly mammoths is coexisting in a continent the size of Australia, and the reason for this is hand waved, roughly anything that walks on land is smart enough to have a language and participate in a peaceful utopia alongside humans, large not-quite-lingual pterosaurs can take off and fly while carrying humans, and small ceratopsians can speak any language. But Gurney is also up-to-date on the world of paleontology, and although his raptors were naked in early books, he painted them with feathers in later ones. And everything has the right physiology. Dinotopia is a children's story with enormous detail in the dinosaurs.
  • While they aren't about dinosaurs, Steve Alten's Meg novels will make paleontology enthusiasts cringe. The opening scene of the first book has a T. rex chasing some hadrosaurs into the water, where it is eaten by a Megalodon explicitly stated to be twice its size. *sigh* Carcharodon megalodon did not live during the Cretaceous (the giant shark appeared 47 million years after the dinosaurs died out).
    • Interestingly, though, there was a giant shark species that did live contemporaneously with the Cretaceous mosasaurs, and did prey on them, with ample fossil evidence from mosasaur bones (though the big Mosasaurs also preyed on them in return as well). It was Cretoxyrhina, the Ginsu Shark, and could grow over 30 feet long, and a 30 foot marine animal could potentially reach up to twice the mass of a T. rex, if not twice the length. Though the Ginsu Shark did go extinct before the end of the Cretaceous and would not have been contemporary to T. rex.
  • Mentioned in the sci-fi novel The Sky People by S. M. Stirling, due to Ancient Astronauts terraforming and seeding Venus with Earth lifeforms. There are also beautiful cave princesses in fur bikinis, much to everyone's delight.
  • Kronos. It rapidly becomes apparent that the author did not do any research whatsoever on plesiosaur biology. Among the worst is the eponymous Kronosaurus swimming in an up-and-down body motion like a whale, complete with flukes. The problem? Plesiosaurs had a stiff spine and were virtually forced to swim sealion or penguin style. Seeing as the author has a severe creationist lean, this F in biology could be due to not doing any research at all and trying to Dan Brown it. The author has several other books involving prehistoric life, which likely contain other issues.
  • Partially justified in the Conan story Red Nails. Conan encounters a "dragon" (which is obviously a dinosaur) - but despite the fact that the story is set "only" ten or twenty thousand years ago, the dinosaur is not a natural survival, but an extinct creature reanimated from fossils by powerful wizards.
  • The back cover of the novelisation of Doctor Who and the Silurians boasts that the story contains "a 40 ft. high Tyrannosaurus rex, the biggest, most savage mammal which ever trod the earth!" No T. rex fossil ever found has been that big; the largest one is 40 feet long from nose to tail. And then there's that other bit — while most of us aren't experts on the subject, we could probably tell you that T. rex was not a mammal..
  • In the Edgar Rice Burroughs novel Tarzan at the Earth's Core, a Stegosaurus is described as jumping from a height and using its plates as a gliding mechanism. Funnily enough, there was a hypothesis in 1920 which proposed that Stegosaurus used its plates to glide.
  • There is a children's book called Day of the Dinosaur which commits this sin in spades. None of the dinos are illustrated correctly and they all are depicted as living around the same time. Also, Dimetrodon, Mesosaurus and Eryops are called dinosaurs. (For those who don't know, Eryops was a newt-like amphibian that was roughly contemporary of Dimetrodon. It's portrayed as a land animal in the book. Also, the three foot-long Mesosaurus resembled a crocodile and lived at the same time as Dimetrodon and Eryops, but farther south. A filter-feeder, it was one of the first reptiles to return to an aquatic existence. A related coloring book makes it out to be a predator about thirty feet long, probably getting it mixed up with Mosasaurus.) To be fair, the book was from the sixties, so some of this is Science Marches On, but the rest is simply inexcusable, as this review points out.
  • The Berenstain Bears book "At the Dinosaur Dig" averts this for the most part save for two major mistakes: Dimetrodon was referred to as a reptile and Mosasaurus was described as being bigger than any shark (C. megalodon was larger).
    • The Berenstain Bears and the G-rex Bones also averts this when the eponymous G-rex (short for Gigantosaurus rex) was proven as a hoax by pointing out that while the dinosaur is twice the height of Tyrannnosaurus, its bones are only twice as thick, and the laws of physics suggests that it would be impossible for animal with T. rex's body shape to be twice its height otherwise its bones would have to be so thick that there would be no room for flesh and internal organs. This is somewhat true seeing as how that the carnivorous dinosaurs larger than T. rex are merely roughly the same height at the hips or, in the case of Spinosaurus, even shorter. Who knew Berenstain Bears went there?
  • A Thomas the Tank Engine picture book was actually about Thomas and Stepney finding a Tyrannosaurus rex skeleton on Sodor, despite that dinosaur being native to North America (they really should've uncovered a Proceratosaurus, Eotyrannus, Yaverlandia, Becklespinax, Valdoraptor, Megalosaurus, Sarcosaurus, Aristosuchus, Calamospondylus, Iliosuchus, Metriacanthosaurus, Eustreptospondylus, Duriavenator, Neovenator or Baryonyx, all of which are actually theropod dinosaurs that are native to England). Well, at least the dinosaur skeleton the Narrow Gauge locomotives found in the show is actually that of a Dacentrurus (a large stegosaurid native to England).
  • this one, which is just one big Critical Research Failure from beginning to end. For starters, it has herbivorous plesiosaurs, states that Ceratosaurus was a tyrannosaur (right, and you're a tarsier), claims that Tyrannosaurus rex grew to 65 feet long (try 42 feet), has naked raptors, claims that Oviraptor lived on eggs (discarded in the nineties), has aquatic sauropods (disproven in the sixties, while the book was written in 2003), says that Archaeopteryx evolved after the raptors and has really lame 3D.
  • Dinoverse, while mostly suffering from Science Marches On, has a weird disconnect between the illustrations and the text. The illustrations are all accurate for the time, but in the text Tyrannosaurs can casually slap their tails on the ground and are twenty feet or so tall, as if they were the archaic tripod-bodied types and not the horizontally-oriented ones in the illustrations. Mentions are also made of the lips of creatures which are beaked.
  • The Geronimo Stilton book "Valley of the Giant Skeletons" managed to pass a Psittacosaurus skeleton as a Tarbosaurus skeleton. Most of the palaeontology stuff is okay, though.
    • Played painfully straight, however, in the spin-off series Cavemice, which is basically just another version of The Flintstones with mice.
    • The spin-off graphic novel Dinosaurs in Action has the main cast go back 140 million years ago in the Cretaceous Period, but they encounter both North American and Asian genera that lived 80 to 66 million years ago. The genera featured include a flexible-necked Elasmosaurus, a Quetzalcoatlus more closely resembling an oversized Pteranodon, and a sparsely-feathered egg-stealing Oviraptor (though it was at least described as an omnivore). On the other hand, Velociraptor is surprisingly anatomically accurate, even being coated in feathers.
  • Jane Gaskell's Atlan novels take place in a fantasy prehistory that includes, among other oddities, people using dinosaurs (which are simply referred to as "dinosaurs" with no other description) as transportation. The conceit of the series is that it's humanity's true origin story, which makes the anachronisms stick out all the more. While the narrative is indeed based on long-outdated sources, humans coexisting with dinosaurs does not feature in any of them. More likely, this element comes from the works of Edgar Rice Burroughs.
  • Played with in the Annals of Improbable Research article The Taxonomy of Barney, which, after noting Barney's un-dinosaur-like behavior and revealing through an X-ray photograph that Barney's skeletal structure is indistinguishable from that of Homo sapiens, rules out the hypotheses that Barney is more closely related to dinosaurs or dead fish than humans.
  • In 2010, National Geographic published The Ultimate Dinopedia: The Most Complete Dinosaur Reference Ever, which, despite it being written by children's paleontology writer "Dino" Don Lessem, is full of errors. Observe:
    • Classification brainfarts abound (ceratosaurs are often confused with ceratopsians, while dromaeosaurids are said to include many non-dromaeosaurids).
    • Several long-discredited theories (placement of coelophysoids in Ceratosauria) are treated as fact, as well as hypotheses that are questionable (synonymizing Triceratops and Torosaurus).
    • Inaccurate size estimates (the giant carnosaur Chilantaisaurus is listed as being 10 feet long).
    • Hit-and-miss illustrations (inaccurately feathered coelurosaurs are persistent).
    • An incomplete dinosaur list (the tyrannosaur Bistahieversor is listed, although the megalosaur Leshansaurus, which was published a month before, is absent).
  • Averted in The Magic Tree House movie: the dinosaurs featured lived at the same time and place, Pteranodon is anatomically accurate (toothless, quadrupedal, described as fuzzy, bulky, and has pteroid bones) and takes off with its wings, Alamosaurus has a brachiosaurid-like body instead of a diplodocid-like one, and Tyrannosaurus has non-pronated hands. On the other hand, Pteranodon is too big and is shown living inland and at the end of the Cretaceous, the hadrosaurs have visible fingers, and pterosaurs were referred to as dinosaurs in a book.
  • Dinosaurology (a 2013 installment in Dugald Steer's Dragonology series) attempted to subvert this trope, with the inaccuracies that may pop up being Hand Waved in that the book is meant to be the translated copy of a traveler's journal.
  • Referenced in an Encyclopedia Brown story. The con artist Wilford Wiggins claims to have discovered caveman drawings in an old cave. He almost becomes rich and famous for the "discovery", but Encyclopedia notices a drawing of a caveman fighting a dinosaur. He points out the dinosaurs went extinct long before the age of man, and Wilford's con is exposed.
  • Averted in The Dinosaur Lords when it comes to names confusion and biology. The many dinosaurs from different eras co-existing are explained by the fact that Paradise is likely an artificially-colonised world, and the premise of the story - medieval knights on dinosaurs - is just pure Rule of Cool.

    Live-Action TV 
  • Destination Truth, the 'flying dinosaur' episode. Lets see, they identify the creature from the descriptions as a pterodactyl, yet never, not ONCE say its a flying reptile, not a flying dinosaur. The closest thing to a flying 'dinosaur' are the birds, NOT the pterosaurs, which are a completely separate taxon.
  • Super Sentai and Power Rangers mostly fall into the Stock Dinosaurs trap and include creatures that technically aren't dinosaurs; of the three dinosaur-based series all three include pterosaurs, Zyuranger/Mighty Morphin' has two mammals (a mammoth and a sabertooth tiger) and a Not Zilla, Abaranger/Dino Thunder has a dimetrodon, and Kyoryuger/Dino Charge has a plesiosaur. Go-Onger/RPM also has a set of dino mecha with a mammoth.
    • The three Sentai series and Dino Charge also tend to show all the dinosaur species existing together regardless of the fact that they were eras apart; though at least in Abaranger's case this coexistence is explicitly an Alternate Dimension where they survived the extinction event(s).
    • Zyuranger/Mighty Morphin' depicts the Tyrannosaurus mech as dragging its tail, though that might have more to do with it being the only individual Guardian Beast/Zord with a suit actor.
    • Outside of the dinosaur-themed series, the time-travel themed Power Rangers Time Force has a trip to prehistoric times where the Rangers both get chased by a Tyrannosaurus and find a painting of a time-tossed zord. They also have Cretaceous fauna in the Jurassic period (the only dinosaur that should be there is the Stegosaurus).
    • Ironically, the Zords from Abaranger/Dino Thunder were more scientifically accurate in design than the dinosaurs in Jurassic Park III, even though the latter was far more expensive than the former to make and came out only 3 years earlier. Well, except for the Raptor Riders, of course. They did not, however, use correct names for some of them: a Tupuxuara pterosaur was called "Top Galer" in Abaranger and "Drago zord" in Dino Thunder. The latter also referred to a Styracosaurus as the "Mezodon" zord.
    • Kyoryuger/Dino Charge seems to be pretty far behind. While the Tyrannosaur doesn't drag his tail, almost every bipedal dinosaur has scaly skin and pronated hands. The Tyranno even has three fingers on each hand! And while the T. rex is feathered in Kyoryuger, Dino Charge has been known to forget that detail in its original footage; and neither show includes feathers on the Velociraptor. Dino Charge adds another inaccuracy by identifying the Brachiosaur as a "Titanosaur" (likely as a Mythology Gag to Mighty Morphin''s Brachiosaur, Titanus, but still).
      • Kyoryuger also makes the mistake of showing a Spinosaurus as a completely land-based creature, though in the show's defense, the major pile of evidence towards it being partially if not completely water-based didn't drop until shortly after the show ended.
  • The Dinosaurs sitcom had an... unusual take on this concept. The writers consciously did no research in order to get in more jokes. As such, we have things like Allosaurus and Tyrannosaurus living together, carnivorous Triceratops (although the theory that they may have been omnivorous is getting more currency, of late), and cavemen (and mammoths and mastodons were mentioned). They also live in 60,000,000 B.C., 5 million years after the dinosaurs should have become extinct (oddly enough, the last episode of the series features them going extinct). They are living in houses complete with refrigerators and eight-track tape players, so we really can't fault them.
  • Lost Tapes has several of its monsters portrayed as Prehistoric Animals. None of them make sense. Goofs includes a surviving Azhdarchid Pterosaur behaving as a modern (albeit giant) Shrike; a people-eating Elasmosaur and a Megalania living in rainforest.
  • The Little Howard's Big Question episode "Could The Dinosaurs Ever Come Back" is a carnival of this. To list a few; a T. rex is shown with three fingers, as well as implying that all dinosaurs lived at the same time (using stock footage from Walking With Dinosaurs) and mentioning "Brontosaurus" like it's still a valid genus.
  • Doctor Who is guilty of a number of egregious examples of this, even more so when you remember that it is aimed primarily at children, arguably the most dino-savvy demographic on the planet. Its most notable flub is its creation of the "Silurians", a race of humanoid-reptilian beings who coexisted with the dinosaurs, despite the fact the Silurian Period (called the "Silurian Era") ended about 200 million years before the dinosaurs evolved, a span of time that tests the limits of the Rule of Cool to breaking point. A later serial attempted to correct this by saying they should properly be called "Eocenes", which is certainly better, but no more right, as the Eocene began about 10 million years after the dinosaurs went extinct. A third attempt to give them a name decided on Homo reptilia, which inadvertently placed them in the same genus as us.
    • One of the main plotlines of the Silurians' oddly-named debut serial relies on humans experiencing "primal fear" when faced with the reptilian monster of the day, even going so far as to regress to a caveman mentality and start painting on walls. But by the time the higher monkeys had split off and begun expansion, the age of the reptiles was long gone.
    • In a rather strange case of Science Marches On, the original introduction of the Silurians occurred in 1970, before evidence from the Moon landings had disproven the idea that the Moon was a captured body from another part of the Solar System. As such, the arrival of the Moon is used as a plot point, as the Silurians went into hibernation to escape it, thinking it was about to collide and destroy them, only to be left sleeping when it didn't happen. Rather ironically, within a decade the idea that the Age of Dinosaurs had been ended by an impactor from space was gaining ground, enough for a later Who serial, Earthshock, to use it as part of its plot.
    • But this is topped by another Third Doctor story: Invasion of the Dinosaurs. Somewhere, a Palaeontologist is Committing Suicide by Placing his Head between Two Convergent Tectonic Plates.
    • "Dinosaurs on a Spaceship" had Ptero Soarers, juvenile Tyrannosaurus that look like the adults and typical pop culture raptors.
  • One episode of 24-Hour Restaurant Battle had a caveman-themed restaurant called The Cave-In. Every single food item was dinosaur-themed, even things like ribs and burgers that could have been named after any animal at all (like, say, mammoths).
  • In the BBC show My Pet Dinosaur, they speculated on human's relationships with dinosaurs had the meteor not hit. Ignoring the likelihood of humans even existing in that scenario, they had sauropods that barked, walked on two legs, and were the size of small cats. They also had a Protoceratops as the equivalent of pigs and chickens, even though ''Protoceratops'' went extinct ''before'' the meteor, and chickens-or at least chicken-like birds-already existed in the late Cretaceous. They also had human-shaped dinosaurs, even though the structure of a dinosaur couldn't have supported that. Also, they had scaly maniraptors. I thought this was speculation, not Looney Tunes.
    • To be fair, they did address the issue of humans coexisting with dinosaurs. According to the cited experts, there is no evidence that any dinosaur ever occupied the arboreal niche of our primate ancestors, leaving it open for them to exploit. Whether this is actually true is up for debate.
  • Primeval doesn't have accurate creature models, but the creators have acknowledged that they do their research - they just decide to deliberately exaggerate things for dramatic effect.
  • Lampshaded in an eighth season episode of The Office (US). While talking about the many unpleasant aspects of living in Florida, Robert California remarks, "Alligators are dinosaurs, Dwight. You know that, right?" Dwight, visibly torn between correcting his boss and letting the inaccuracy slide, quietly answers, "Mmm... it's complicated."
  • Two episodes of Disney Channel's Jessie seem to perpetrate the lizardlike Velociraptor subtrope.
  • Dino Dan is guilty of this:
    • Bipedal, scaly pterosaurs that carry things with their feet and only eat fish (yes, even the Quetzalcoatlus).
    • Not only are the deinonychosaurs not feathered enough, they don't even have the right kind of feathers (real deinonychosaurs had actual feathers, not protofeathers).
    • Mispronunciations of several dinosaur names (Euoplocephalus is pronounced with a hard "C" instead of a soft "C", and Compsognathus is pronounced with an "Ä" sound instead of an "Ā" sound).
    • Pronated hands on the theropods.
    • Elephantine forelimbs on the sauropodomorphs and ornithischians.
    • A Deinonychus skeleton seen in one episode is identified as Dromaeosaurus.
    • Dan translates Corythosaurus as "helmet head" in one episode (it actually means "helmet reptile"; "helmet head" would be "Corythocephale").
    • When discussing Brachiosaurus in one episode, Dan incorrectly identifies an illustration of Apatosaurus as that genus (the book he was reading did actually have a Brachiosaurus illustration).
    • The generic Triassic dinosaurs seen in one episode look like small lizards.
    • Cursorial eudromaeosaurs that hunt in packs (exactly how much they cooperated while hunting is debatable, but it almost certainly wasn't to the same degree as living canids).
    • One episode had a juvenile Tyrannosaurus that looked like a scaled down adult. Juvenile T. rexes were actually slightly more lightly built than adults.
    • Sauropod nostrils in the wrong position.
    • Other assorted anatomical errors (the tail of Brachiosaurus is too long, the skull of Spinosaurus is too tubular, etc).
  • Timecop: Ian Pascoe claims to have witnessed a Megalodon shark rip the throat out of a Tyrannosaurus rex. These animals lived over 47 million years apart, assuming he didn't somehow (?) bring them together.

  • According to the song "Walking in Your Footsteps" by The Police, the mighty Brontosaurus walked the Earth 50 million years ago. In reality, the most recent Brontosaurus remains are nearly 150 million years old, and the extinction of the dinosaurs occurred 66 million years ago.
  • Iron Maiden's "Quest for Fire" mostly retells the story of the eponymous movie... except for the (hilariously overblown) opening line "In a time when dinosaurs walked the earth..." It should be noted that this was probably the band being funny, as they are history buffs and would know about things like this.
  • Danny Saucedo's song "Dinosaur Bones" from the album Drawings of Dinosaurs includes a line about pterodactyls flying in "the Pleistocene sky." By the time of the Pleistocene epoch, pterosaurs had been extinct for nearly 64 million years.

    Newspaper Comics 
  • An early series of FoxTrot comic strips had Jason filming a dinosaur movie, with his pet iguana Quincy as the dinosaur. He called the film "Iguanadon Terror", even though Quincy looked nothing like an actual Iguanodon (Jason was aiming for something like a Dimetrodon, though when asking if Quincy could pass for a dinosaur he was told that Quincy only looked like an iguana with a fan taped to its back).
    • A later strip had Jason doing a claymation movie called "Mesozoic Park"; he pointed out that Jurassic Park was mostly about dinosaurs from the Cretaceous period.
    • In another strip, he was seen writing a letter explaining the brontosaur/apatosaur controversy to a cookie manufacturer that used the former term in the "Fun Facts" of their dinosaur cookie boxes. He then immediately tries to blackmail them into sending him free cookies.
    • Another strip perpetrated the giant Liopleurodon meme started by Walking with Dinosaurs.
    • Played for Laughs in one Sunday strip, where Jason claims Pachycephalosaurus might have hypnotized its predators because its head was so similar to Talosians (despite the fact Talosians have a very large brain whereas pachycephalosaurs are famous for having thick skull roofs which is where they got their name from) and that dinosaurs went extinct because of time-travelling big-game hunters.
  • Bill Watterson, the author of Calvin and Hobbes, admits that his earliest strips involving dinosaurs were pretty embarrassing. After doing some research, and getting as excited about dinosaurs as Calvin, his drawings of dinosaurs became more and more accurate and realistic (as an aside, tellingly, most fantasy sequences in Calvin and Hobbes are drawn in a more realistic way than Calvin's day-to-day life). If you have a collection of Calvin and Hobbes anthologies, note that by around 1994, it's obvious that Watterson invested in a Gregory S. Paul book for anatomy and in a set of "Jurassic Park" action figures for posing and staging. One strip involved such realistic dromaeosaurids that they would scare small children. It didn't help that Calvin was talking about them eating small children. The little freak!
    • Shortly after that strip, Jurassic Park came out, and Watterson stopped putting dinosaurs in the strip for a time so that they wouldn't be negatively compared to the CGI.
    • Watterson doesn't let accuracy get in the way of Rule of Cool. Say it with me: ''TYRANNOSAURS IN F-14s!''
      Calvin: "This is so cool!"
      Hobbes: "This is so stupid."
    • Despite Calvin normally having a callous disregard for scientific accuracy, this trope is amusingly subverted and lampshaded when Calvin and his parents visit a natural history museum. Calvin's mom asks him (in that typical way that moms do when they're trying to encourage their kids to talk about something they like) to tell her about the Stegosaurus statue outside. Calvin goes into a long (and scientifically accurate) explanation of the most likely habits and characteristics of Stegosaurs, until his mom tries to humor him further by asking if the T. rex and the Stegosaurus used to fight each other, leading to this outburst:
      Calvin: Of course not, Mom! The Stegosaurus lived millions of years before the T. rex! Jeez, try not to embarrass me when we go inside, okay?
    • An in-universe case of artistic license occurs when Calvin has an Imagine Spot of himself discovering the fossil of a new theropod, the Calvinosaur. It's as big in comparison to a T. rex as a T. rex is to a human being. The sort of monster any kid would love to give his name to.
  • B.C., perhaps one of the most egregious examples of a newspaper comic that has both dinosaurs and humans. Incidentally, though the creator, Johnny Hart, was a self-proclaimed Christian fundamentalist, the scientific shortcomings seem to be less because of his beliefs and more for Anachronism Stew Played for Laughsnote .
    • After Hart's death in 2007, the strip started to feature dromaeosaurids, which are as usual featherless and no different than the ones in Jurassic Park. One strip did, however, point out how birdlike it was in an amusing way.
  • Alley Oop, starting in 1932, with his pet, Dinny. Before Television!
  • The Far Side had many strips that showed or implied dinosaurs and cavemen living at the same time. However, the strip describing the "thagomizer" has been endorsed by actual paleontologists for giving a name to a certain part of stegosaur anatomy, even though it implied that said part posed a danger to primitive hominids. Gary Larson has said that he is well aware of the anachronism and while part of him justifies the cartoons on the Rule of Funny, part of him feels very guilty about using this trope, especially given the high regard in which he is generally held by the scientific community.
  • One Beetle Bailey strip implies that life has existed on land for only five million years.
  • Dilbert features Bob the Dinosaur, who interacts with modern humans rather than cavemen. At least one strip has implied that he woke up after hibernating for millions of years.

  • Invoked to the hilt in Gottlieb's Caveman, where the player maneuvers the caveman to hunt brontosaurs and pterodactyls while avoiding the Tyrannosaurus rex.
  • Unsurprisingly, The Flintstones doesn't take "artistic license" with paleontology as much as it recklessly abandons it.

  • Karl Pilkington from The Ricky Gervais Show often makes mistakes when it comes to pre-historic life (as he does with everything else), referring to how they lived with dinosaurs and other "facts" he picked up from fictional works. Ricky repeatedly tells him he's wrong and that he's either picked this up from The Flintstones or 10,000 BC and mistaking it as fact.

    Tabletop Games 
  • Prior editions of Dungeons & Dragons handle the various species of dinosaur better than it does mythology, even pointing out the differences between the Velociraptor and the Deinonychus. They still list Pteranodon and Elasmosaurus under the same catchall of "dinosaurs", though; in the Fourth Edition, however, they are renamed Behemoths. Plus still allowing the Quetzalcoatlus and Elasmosaurus to swallow humans whole (note: not only could they probably never do that without dislodging their entire lower beak, but a Quetzalcoatlus with a human in its gut would probably be too heavy to fly).
    • They honestly go in a lot of different directions with this, depending on the edition. At one time, dinosaurs were classified as Beasts (a different creature type from Animals, in much the same way that humans are Humanoids and most invertebrates are Vermin).
  • Genius: The Transgression features a Bardo based on discredited theories of the Hollow World, which seems to be filled with every paleontological mistake ever made, such as brontosaurs (no, not apatosaurs, brontosaurs), the old Victorian notion of what an iguanodon looked like, and Piltdown Men.
  • There is this very obscure, very low-quality board game sold in Hungary that goes by the name Küzdelem a dinoszauruszok földjén (Battle in the Realm of the Dinosaurs). Has only a handful of pictures, all of which contain horrible depictions of Stock Dinosaurs — one Brachiosaurus with a backwards knee, and one with shorter forelegs than back legs, standing as erect as a human; toothed, bat-winged Pteranodons with the bat fingers sprouting from the back of the wings; and gigantic, scaly Velociraptors with Therizinosaurus-like claws. In short, it is the board game equivalent of "Chinasaurs" (see lower).
  • Yu-Gi-Oh! Trading Card Game has a "Dinosaur" type as one of its monster types: the type is mostly made up of the popular dinosaurs listed above, and unfortunately includes a mammoth. An undead mammoth. Fortunately, later, non-zombie Mammoth monsters (such as Big-Tusked Mammoth) are more correctly listed as Beast-Type. They also thankfully averted the "nekkid Raptor" trope with Black Veloci. A lot of the earlier dinos, though, were the classic "nekkid" version (but see also Dinosaurs Are Dragons). The older cards were victims of Science Marches On as noted above; those cards were first released before the feathers thing had been discovered.
  • While we're on the subject of dinosaurs being given powers and placed on trading cards, Dinosaur King.
  • In Dinosaurs Attack!, herbivorous dinosaurs like Parasaurolophus and Stegosaurus eat people frequently and messily, plesiosaurs have bendy necks instead of the stiff ones they had in real life, and trilobites are described as "flesh-eating worms" (real trilobites were not worms and even the predatory ones could not harm something as large as a human). This is in part intentional parody, though, since the 50's movies the cards spoof made similar mistakes.

  • The DinoRiders franchise had dinosaurs from virtually everywhere, plus the obligatory pterosaurs and Dimetrodon. A spinoff line of prehistoric mammals provided another example of this trope, with an entelodont (giant pig-thing) alongside a giant ground sloth, saber-toothed cat, and wooly mammoth. Then again, this is a series that concerns the exploits of aliens waging war on prehistoric Earth with the help — voluntary in the case of the good guys, not so much in the case of the bad guys — of the animals. Rule of Cool heals many a wound.
  • Playschool had a toy line called Definitely Dinosaurs. It featured fully articulated prehistoric creatures, and was meant to be educational... so what are the cavepeople doing there?
    • At least the packaging pointed it out and said it was just for fun. The real question is why the cavemen were all so outlandishly stocky.
  • Tyco's ImagiNext line does the same thing, though it has no pretensions of being educational. Bonus no-prize for the Carnivores Are Mean storyline.
  • Fisher-Price has a line called Imaginext Dinosaurs which is various dinosaur toys (IE: Tyrannosaurus rex, Triceratops, Brontosaurus (sic) along with some commonly-used non-dinosaurs (IE: Sabre-Toothed Tigers, Woolly Mammoths, Dimetrodons, Pteranodons, etc.)...Oh, and cavemen. Considering it's meant to be a science fiction-fantasy-action line of toys for kids, it's somewhat forgivable. However, the real outrage is that one of the toys (which is supposed to be a Dilophosaurus, including the cliched Jurassic Park-inspired frill...which it NEVER had) is called a "Frilled Raptor". Can you hear your inner paleontologist sobbing now?
  • And then, there's Topps' insane Dinosaurs Attack!! trading card series. It's probably a lot easier just to say this: any question as to whether or not they were pointedly invoking the Dinosaurs Are Dragons trope were gone the minute it turned out that the (all carnivorous and homicidal regardless of species) dinosaurs were sent by Dinosaur Satan. In addition, this is one incredibly violent series of cards — rivaling even Topps' own "Mars Attacks" in terms of sheer mayhem. The whole set generally appears to be aiming for Refuge in Audacity writ large.
  • Much of the dinosaurs found in Dollar Stores are guilty of this trope. Case in point, at least one Dollar Store has toys for sale that include a Ceratosaurus labelled as an Oviraptor and a Dimetrodon labelled as Spinosaurus.
    • And there exists one such "Chinasaur" package that depicts a T. rex eating a huge lump of grass... maybe it was hay, but in either case, it was not flesh-colored. The toy makers must have been living in a cave their whole lives.
    • Gary Gygax created a handful of the iconic monsters of Dungeons & Dragons when he bought a bag of toys to use as miniatures which could only have been called "dinosaurs" euphemistically, despite this being what the bag was labelled as. The rust monster was inspired by what looked like a cross between a flea and a lobster with a propeller on its tail. Only a handful of the rest were anything close to dinosaur-shaped. For reference, the Bulette is probably the most dinosaur-like of the monsters that share this origin.
  • In general, most toys would be more accurately conveyed in the term "Prehistoric long dead things in colorful poses," but that would not please many parents.
  • Check out this tiny "Carnotaurus" from a German toy series, called Predators. The only research the sculptor made most likely stopped at "carnivorous dinosaur with horns". Quite strange, considering the series has models of other, much more obscure and yet better sculpted animals. Though it also has a Sauropod calling itself a Lystrosaurus, a naked raptor, and a Theropod labeled "Megatherium". The linked blog offers a variety of similarly exquisitely bad Chinasaurs.
  • There exist several lines of cheaply made Transformers-ish figures, all of which turn into dinosaurs, following the same general pattern: back legs become arms, the legs are formed from the belly, the tail splits in two to become shoulder-cannon mounts, and the head ends up on their chest (or in some cases lower, which lead to TF fans dubbing some of these toys "Dinocock Prime"). There is one figure called Deinonychus-Bot, however the actual toy turns into a harmless and cute-looking basal ornithopod/iguanodont! For some reason, this makes the toy all the more badass.
  • LEGO's Dino line of sets feature standard, JP-styled critters, including a scaly, kangaroo-handed raptor. The figures are still leagues better than the ones from ''Adventurers'' or ''Dino 2010/Dino Attack'', though.
    • Ever since biomechanical dinosaur cyborgs got introduced to LEGO's BIONICLE canon, fans have eagerly waited for one to appear in an illustrated form of media. The graphic novel Legends of Bara Magna finally depicted one, but it was a one-panel wonder of a stereotype Flintstones-styled tail-dragging "Brontosaurus" with what looked like miniature lamp-posts sticking out of its cyber-head. But then it kicks in: this is an aversion, since Bionicle animals have never looked realistic.
  • The Playmobil dinosaur line largely averts this: the Pteranodon has a toothless beak, most of the theropods have non-pronated hands, the spinosaurid is larger than the tyrannosaurid, etc. The only real caveat is the lack of feathers on the deinonychosaur.note 
    • The Pteranodon does have one major error, though: Digitigrade feet used for perching in trees. Pteranodon had plantigrade feet and lived mostly on the ground when it wasn't flying. At least the resulting visuals are impressive.
  • There's a set of models called "Prehistoric Digs". The advertising copy for them in the catalog says, "Discover a hidden 3D dinosaur skeleton! Then assemble the scattered bones to reveal your very own 10" museum quality reproduction of a 70 million year old 3D dinosaur skeleton. Specify T-Rex, Triceratops, Stegosaurus, or Mammoth."
  • Jurassic Park's Chaos Effect line of toys relied entirely on the Rule of Cool with its insane Mix-and-Match Critters. This is a pretty abstract concept to begin with, though there were instances where you had to wonder how these mutants came to look the way they do, considering what species they're composed of. Velocirapteryx, for example, is said to be a Velociraptor combined with an Archaeopteryx, yet the figure features an elongated pterosaur-finger for a wing, which neither of these had, and said finger serves as an attachment point for the wing feathers, when these really grew out of their second fingers. Also, since Velociraptor and Archaeopteryx were nearly identical-looking dinosaurs anyway, if we did mix them together, the differences between the base dinos and the resulting mutant would hardly be all that apparent (it would be like mixing together a wolf and a jackal). However, as far as the feathers go, there's a fair bit of Science Marches On taking place, because it was only discovered later on that Velociraptor itself was feathered, which makes the figure Hilarious in Hindsight.
    • In the regular toy line, Tanystropheus is portrayed as able to constrict its victims with its long neck like a python. Real Tanystropheus couldn't do this - their necks were relatively stiff, and scientists believe that they mostly ate small prey like fish.
  • In Transformers's Power Core Combiners line, the Dinobot Grimstone is misidentified on his box as a Triceratops, whereas he's really a Styracosaurus. Eh, easy mistake to make, especially since he has a stylized, robotic dino-mode. But worse, his Dimetrodon-drone is said to be a Spinosaurus on the same package!
  • The Dino Valley lineup of Chap Mei Toys is the embodiment of this trope. It has scaly raptors and pterosaurs, Pteranodon with a beak full of teeth and an additional Tapejara-esque crest, a bizarre cross between an Ornithocheirus and a rhamphorhynchid labled as Pterodactylus, an Ornitholestes (referred to as "Dragonosaurus" in some packaging) with a crest on its snout and raptor-like footclaws, a featherless egg-stealing Oviraptor, double-crested spinosaurids, a frilled Dilophosaurus with a sail and only two toes, bendy-necked plesiosaurs, a Carnotaurus with a small nose horn and tyrannosaurid-like arms, and a Brachiosaurus with a diplodocid-like body.
  • while Rebor dinosaur figures have been praised for their incredible detail they haven’t done well when it comes to accuracy. two egregious examples are their Yutyrannus figure, a dinosaur famous for having feathering barely having any on their figure and there baby Velocitaptornote  triplets which had absolutely no feathering on them and suffering from shrink wrapping.

    Video Games 
  • Averted in Jetpack Brontosaurus. As the game acknowledges, the title character is an Apatosaurus. Brontosaurus is just his name. It also takes pains to use the Order name Pterosaurs in the introduction, some of which were contemporary with the Apatosaurus, rather than a specific genus that might not have been. All other weirdness can be written off to it taking place in a surreal dream world. Then again, it's made by the same people as Raptor Safari, below, which similarly delights in being much, much more scientifically accurate than such a blatantly ridiculous game needs to be.
  • The "naked Velociraptors" subtrope is happily averted in FlashBang's Off-Road Velociraptor Safari, of all places. Bonus points for the Perpetual Molt effects.
    • As to not be unfairly complimentary, those aren't Velociraptor. They look like excessively gaudy Utahraptor.
  • Yoshi, anyone? Super Mario World featured Dinosaur Land, which was inhabited by Yoshis (who are variously referred to as dinosaurs and dragons, depending who you talk to). So within the whole Mario canon, we have dinosaurs who live among humans, fly or spit fire, swallow other creatures amphibian-style and turn them into eggs, which they then use as missile weapons! And later on they had a limited form of speech.
    • Dinosaur Land isn't entirely filled with dinosaurs, but has quite a few. Reznors are chibi Triceratops... that breath fire. Rex isn't based on a Tyrannosaurus Rex like the name would suggest, but rather a purple celtic dragon. That doesn't breath fire.
  • World of Warcraft:
    • In the Barrens and Durotar, there are the most stereotypical predatory dinosaurs in the world, though given slight makeovers. Raptors (the dinos, not the bird) are even the racial mount of trolls. To be fair, if there are dragons, yetis, green-skinned shamanistic weird people, and giant blue satyrs with tentacles growing out of their faces, there may as well be dinosaurs.
    • Un'Goro Crater is a zone devoted to a mashing-together of various popular dinosaurs and other prehistoric animals. Their versions of pterosaurs, raptors, stegosaurs, dimetrodons, and T-Rex-like creatures all hang out within a few city blocks of each other. Along with gorillas. It, along with Sholazar Basin, is really an homage to Land of the Lost (all that's missing are the Sleestaks), and probably any other movie/show that has a hidden valley of dinosaurs. With a dash of Nintendo thrown in.
    • Animal and vegetable fossils are a subset of the Archaeology skill, and include a rare pet and mount that are both magically reanimated fossilized raptors, implying that Azeroth's raptors have been around for a very long time. (Probably long enough to evolve off their feathers, pick up the carnotaur-esque horns, and gain the sentience the game keeps pointing out.) There's even a nod to feathery raptors with the Feathered Raptor Arm item, though it's promptly lampshaded in the item's own description as just-as-likely belonging to one of Azeroth's hojillion other magical abominations. Also mentioned are the possibility of still-living giant trilobites, and while the entry on the nautilus shell says all the shelled squids in the world are extinct, there's two very large examples hanging out in Vashj'ir.
    • Brought Up to Eleven with the Pandaren Isle of Giants, in which all sorts of monstrously large dinosaur-esque creatures are put in groups wandering about on the island. The island itself is a blatant Shout-Out to the Jurassic Park movies, there is even a camp site outright named so.
  • At one point during the director's commentary for The Deadly Tower Of Monsters, said director says he got complaints about the inaccuracies of a meat eating sauropod, which he refers to a s a stegosaurus. And then there were the fire-breathing pterodactyls.
  • Guild Wars has dinosaurs on the Tarnished Coast in Eye of the North. The Tyrannus and Raptors are relatively accurate, the Ceratodon somewhat less so (it's an armored ceratopsian with one horn on its forehead and two more on its shoulders). Hard to tell what the Ferothrax and Angorodon are supposed to be, though...
  • One of the recurring enemies in Final Fantasy VIII is a red T-Rexaur (Tyrannosaurus rex). Odds are that many first-time players got offed by one during their first hour of playing by accidentally wandering into the forest area in the Balamb Garden training center.
    • On the other hand, all monsters in the game are actually from the moon, so a red dinosaur is really the least its problems.
  • The far past of Chrono Trigger features an ongoing war between mammals and dinosaurs, the latter being led by the Reptites. The dinosaurs and Reptites eventually became extinct during the ice age caused by the fall of Lavos to Earth.
  • Played with in Fossil Fighters, a mons game which has you digging up fossils and reanimating the dinosaurs within. The "vivosaurs" are explicitly different from dinosaurs and have different traits and names than real dinosaurs do (it's explained that's a process of the revivification device) but there is a section that lets you see what creatures they were based upon. There's even a smilodon, properly called a smilodon by the game.
  • Mostly averted with Paraworld, which has a few minor issues that are mostly explained away with Rule of Cool or lampshaded by the protagonists (All dinosaurs living at the same time, ice age mammals being counted as dinosaurs, and extremely oversized Triceratops and Tyrannosaurus [Although even then, they are referred to as Tyrannosaur Titan and Triceratops Titan and more realistically sized versions can be seen roaming the maps; the third Titan is a Seismosaur that is only about half again as big as a real one]).
  • Dino Run, considering the premise of the game, for starters, involves the "instantaneous extinction" trope. And the raptors supposedly find shelter and escape said apocalypse and go on to live for an indefinite amount of time.
  • In Star Fox Adventures, there's an item called a Dinosaur Horn. It's associated exclusively with the Snowhorn, a tribe of wooly mammoths.
  • Worlds of Ultima game Savage Empire points out in the manual that humans and dinosaurs lived millions of years apart... While you encounter both in the game. There are also human tribes from different parts of the world from different times. A major element of the plot is to find out why and how these were all brought together into one valley.
  • The Tekken character Alex is a predatory dinosaur living alongside humans in the 20th Century. However, he was genetically engineered from fossils by scientists, partially averting this trope as Alex is more Genetic Abomination than Dinosaur.
  • The Dino Crisis series likes to play Art Major Biology with the dinosaurs it features.
  • Justified in Live A Live. Pogo's chapter, set in prehistory, has a Tyrannosaurus Rex as its final boss. This is the only dinosaur in the entire chapter, and it is worshipped as a god by the Kuu tribe, who offer it human sacrifices. It's also the current manifestation of the demon king Odio.
  • This is played straight with the mammoths of The Elder Scrolls V: Skyrim, though it is largely for the Rule of Cool. Averted by the Sabre Cats, which are surprisingly accurate to sabertooth cats in the genus Smilodon.
  • Played for Laughs in Zoo Tycoon 2, in which Stokesosaurus wears glasses when painting. Not that the game didn't have plenty other examples, however (the likely herbivorous oviraptorosaur Protarchaeopteryx was portrayed as a generic carnivorous coelurosaur, to name one of the better examples).
  • Happily averted (anatomically at least) in the Japanese Xbox game Dinosaur Hunting, which even includes feathered maniraptorans and a T. rex with a feather crest. Unfortunately the theropods still have pronated hands, Dilophosaurus has a frillnote  and spits venom, the plesiosaur necks are flexible, and some of the animals are enlarged for dramatic effect (not counting the albinos and mutants).
    • There's also an Accidentally Accurate example with Spinosaurus, which has proportionally short hind legs.
  • Animal Crossing does a weird take. The museum exhibit plaque for the Stegosaurus states that the animal in question is from the Late Cretaceous, when Blathers (correctly) describes it as living in the Jurassic.
    • And then there's the Seismosaurus, which is now considered to be a dubious genus. New Leaf, however, fixes this and renames it Diplodocus.
    • In City Folk, Blathers claims Apatosaurus lived in lakes and swamps because of its size and weight, an idea that was disproven in the 1960s.
    • In New Leaf, the exhibit plaque for the Pteranodon describes it as the ancestor of modern birds, when Pteranodon wasn't even a dinosaur to begin with. But that's pretty much the only major blunder in the museum fossil descriptions.
  • Pokémon tends to avert this with the information given to their fossil Pokémon. The designs can be forgiven due to Rule of Cool.
  • Surprisingly averted in the third game of the Tak and the Power of Juju franchise, which had a hairless mammoth in a desert environment.
  • With the reveal of one of the newest Bird Wyverns, Monster Hunter manages to play with this trope. Pre-Monster Hunter Xnote  all of the Theropod Bird Wyverns are essentially, super-powered raptors, similar to the Jurassic Park raptors in appearance. With the introduction of the Maccau and Great Maccau, the aversion happens. While still absolutely massive compared to real-life raptors, they're sporting a notable bright green feathered coat (except on their face/neck, lower arms/legs, underbelly and tail).
    • But their hands still are paw-like (as with the raptors in Jurassic Park), while real raptors weren't even able to twist their hands like that.
  • Far Cry Primal:
    • Though the game is supposedly set in Europe 12,000 years ago, a lot of the often stock Prehistoric fauna would rather feel at home in North America (sabertooth cat Smilodon, direwolf, Californian tapir, jaguar, bald eagle) or Asia (crocodile, yak, langur monkey, brown rat, wild chicken).
    • Bigger Is Better too. In-game sabertooths and wooly mammoths are twice the size they were in real life.
    • A promo claims that in 10,000 BC, humanity was on the brink of extinction. This wasn't even close, unless you judge the numbers then by the current ones sustained by civilization. Human numbers actually boomed after the end of the last ice age, for obvious reasons.
    • The "behind the scenes" featurette also makes the common mistaken claim that prehistoric people dropped dead at 30.
    • The game also makes the usual mistakes of portraying sabertooths as fast and cave bears as carnivores.
  • Jurassic Marsh in Plants vs. Zombies 2: It's About Time is a huge offender on this. The dinosaurs shown are Velociraptor (no feathers, much bigger than a zombie), Stegosaurus (has a long neck, isn't meant to exist in the same time period as Velociraptor) and Pteranodon (Toothy Bird, carrying zombies off with its feet).
  • In Mass Effect 2 (set in late 22nd century CE), The Illusive Man describes a certain 37 million year old artifact as from the time when mammals were taking their first steps on Earth. Sorry TIM, but mammals first evolved somewhere between 167 million BCE and 225 million BCE (not too long after dinosaurs).
  • ARK: Survival Evolved relinquishes almost (key word being almost) all accuracy in favor of being as cool and convenient as possible. Examples include:
    • The giant millipede Arthropleura is shown as a ferocious carnivore with acidic blood, despite the fact that it probably ate plant matter, with no evidence of the acidic blood.
    • The Compsognathus and Utahraptor have only some feathers on their neck or arms; and are nekkid otherwise. The Troodon and Therizinosaurus are slightly better off, but only have pennaceous feathers on their arms, with only downy fuzz on the rest of the body. The former also has a venomous bite.
    • The Dilophosaurus is pretty much a carbon-copy of Jurassic Park's. Interestingly enough, the Titanoboa also has a venomous bite and frills, despite being a CONSTRICTOR SNAKE.
    • The Pteranodon have teeth and a deformed wing structure, and are capable of carrying a fully-grown human. Also, both sexes are depicted looking exactly the same, when the females are smaller and lack the large crest.
  • The upcoming game Saurian deliberately attempts to avert this, with extensive research, input by numerous paleontologists, and an actual dinosaur on their production team for reference (an emu) to make certain their recreation of the Hell Creek Formation during the Latest Cretaceous is as accurate as possible, containing only species that were for certain present in that region during that time.

    Web Comics 
  • There's another "Raptor" who looks like he's just walked off the set of Jurassic Park in the Webcomic The Adventures of Dr. McNinja. However, given that the story that introduces Yoshi also includes Raptor-riding banditos, a conspiracy involving Ronald McDonald and MySpace, and a man whose incredible abdominal muscles have somehow transformed into a built-in jetpack (and the eponymous character, the only physician in a long line of legendary Irish Ninjas whose office is in the middle of a haunted forest and whose secretary is a gorilla), once again, the MST3K Mantra is in full effect.
    • The "birdasaurus" in a later plot line, lampshaded with the mouseover "I hope my completely made up out of my mind with no reference whatsoever way of drawing the birdosaurus doesn't upset any of you junior paleontologists."
    • Apparently the author still gets regular emails complaining about this, as he defensively mentions in a Note From Ed in this comic.
    • Taken to absurd extremes with the horrorsaurus, a wingless, flying, tentacled monstrosity with four eyes. That one may have been artificially created by the other dinosaurs though.
  • Dinosaur Comics has a T. rex, a Dromiceiomimus, and a Utahraptor, grossly out of scale. The fact that they're talking is a good sign that it's not supposed to be exactly realistic. There's also the house, car, and woman getting stepped on to indicate something's not right with the timing. It often lampshades the concept, as well:
    T-Rex: Guess what I got last night? A dog! Did you know that dogs and dinosaurs co-existed?
    Dromiceiomimus: Yes, I accepted it without questioning!
    • Lampshaded and more or less (anachronism aside) averted in the guest comic by Aaron Diaz. And then it is deliberately double subverted...
    • It's actually possible to avert this by typing "&butiwouldratherbereading=somethingmorehistoricallyaccurate" after the comic of your choice. (Or at least avert to a greater degree. Pennaceous feathers on T. rex is unlikely, but at least they have feathers.) Here's an example.
  • xkcd has Jurassic Park-style Velociraptors, which the author found traumatizing upon seeing said film.
  • 8-Bit Theater does a brilliant Lampshade Hanging in this strip. Also counts as a Crowning Moment of Awesome (and Funny).
  • Karate Bears finds dinosaurs sometimes. like here they also supposedly once coexisted with dinosaurs
  • Played for laughs in The Order of the Stick when Roy is confused by the appearance of a Brontasaurus, when he knows it's a mixup of parts from different animals. His host points out he didn't have a problem with the hippogriffs.

    Web Original 
  • The Tyrannosaur Chronicles: Mostly averted. Lampshaded by Layla Oviraptor, who mentions that Desdemona Deinonychus and Larry the Tyrannosaur shaved off their feathers so they could star in Jurassic Park.
  • This article. It makes tons of mistakes with animal relationships (claiming that Gastornis is close to kiwis and ostriches when it's really closer to ducks, and Hyaenodon close to raccoons when it's equally close to all carnivorans), confuses the "classic" saber-toothed felids with the saber-toothed sparassodont ("marsupial", in the article's words) Thylacosmilus, serves up an unhealthy serving of Anachronism Stew (Gastornis and Andrewsarchus actually died out long before the Pleistocene), makes unwarranted assumptions about ancestor-descendant relationships, and implies that dinosaurs are cold blooded.
    • Their video about the cassowary not only suggests that pterosaurs are dinosaurs...but it goes on to suggest that pterosaurs evolved into birds. About the only similarity between pterosaurs and birds is the fact that both groups can fly.
    • This one is better, though it implies tyrannosauroids to be carnosaurs (universally rejected since The '90s).
    • The article "5 Weird Directions Human Evolution Could Have Taken" treats the existence of "the Boskop Man" as a fact, which in reality it most likely isn't.
    • In addition to implying the basal archosauromorph Sharovipteryx to be a dinosaur, this article uses a highly fanciful reconstruction of the taxon taken from an extremely unreliable source.
  • Several paleontologists have satirized the sensationalist nature of typical dinosaur documentaries on their blogs as well.
    • This April Fools' joke on Tetrapod Zoology sets out to "prove" that old-school dinosaurs are correct after all, and contains a number of jabs at some infamous fringe groups.
  • Lampshaded during the loading screen of an older LEGO game, Dino Quest, based on the Dinosaurs toy-line, which has Dr. Kilroy commenting on the inaccuracies of the game and spouting well-researched paleontology trivia. But even he gets one thing wrong: flowering plants were around in the Cretaceous.
  • Lampshaded in Welcome to Night Vale. Cecil initially refers to Pteranodon as dinosaurs. Later (after being re-identified as pterodactyls) Cecil is informed that Pteranodon and pterodactyls are not in fact dinosaurs.
    • Doubly subverted in a much later episode. Lauren, like Cecil, refers to Pteranodon as dinosaurs. Kevin immediately informs her that Pteranodon are not dinosaurs. They're arachnids.
  • The Brainpop minigame "Life Preservers" explicitly states that birds are dinosaurs but are dinosaurs themselves. This makes absolutely no sense; even though birds can fly and are the only dinosaurs alive today, there's no objective reason to consider birds special compared to other dinosaurs in this regard. You'd think an educational website would know better.
  • "Meet the Pseudosaurs" parodies this trope all over. A God-Mode Sue T. rex, bendy-necked sea serpent-like Plesiosaurus, deadly featherless Raptor, vicious bird-footed "Pterodactyl", Killer Rabbit Compsognathus and "spitting" Dilophosaurus are all included.
  • Parodied in asdfmovie, where a sauropod keeps calling itself a Stegosaurus.
  • Palaeo Fail was made in order to mock occurrences of these all over the internet.

    Western Animation 
  • The Magic School Bus episode "The Busasaurus" carefully averted this trope based on the paleontological knowledge when it was made. The Frizz took the class back in time 67 million years (Late Cretaceous Period) specifically to correct Carlos (and the audience) on several pop-cultural misconceptions, the biggest of which was that all dinosaurs were predators. Of about a dozen different species they encounter in the episode, exactly three were carnivorous. The Licensed Game loosely based on the episode, The Magic School Bus Explores in the Age of the Dinosaurs, was similarly studious. However, Science Marched On:
    • Troodon and Ornithomimus were more likely omnivores rather than straight carnivores as depicted.
    • Tyrannosaurus as the largest theropod may have also marched on: Carcharodontosaurus, Giganotosaurus and Spinosaurus were potentially larger.
    • And, again, featherless coelurosaurs.
    • The episode also had a bit of Anachronism Stew with Parasaurolophus, Maiasaura, and Pteranodon existing 67 million years ago, when these are three reptiles that disappeared about 5 million years before then, and Pteranodon was portrayed as living inland. Edmontosaurus (or Anatosaurus, depending on who you ask) would have been a better substitute for Maiasaura and Parasaurolophus, and Quetzalcoatlus would be a more accurate fill-in for Pteranodon. At least this episode decided to stick with late Cretaceous dinosaurs.
    • Commendably, their token sauropod is the late Cretaceous American species Alamosaurus instead of any Jurassic stock sauropods. Too bad its teeth are completely wrong.
    • Basal synapsids were identified as reptiles in the Licensed Game.
    • The mini-game "Dino Madness" has birds as non-dinosaurs but still described as dinosaur descendants. Strangely enough, Wanda addresses the idea that birds are dinosaurs in the classroom area of the game. Not to mention Archaeopteryx is identified as a dinosaur.
    • In what may also count as another Science Marches On example, the game uses the name "Rioarribasaurus", which is a name used for the Ghost Ranch coelophysoid material before it was redesignated as the lectotype of Coelophysis itself.
    • The game does make a few errors, however, such as claiming plesiosaurs and ichthyosaurs being the only types of marine reptiles and featuring what appears to be a snake in the Jurassic Period (advanced snakes did not evolve until the Cretaceous).
  • Dinosaucers used Apatosaurus/Brontosaurus confusion as a Running Gag. When told that "Brontosaurus" was an incorrect designation and that Apatosaurus was the correct one, Bronto Thunder would immediately reply "That's a girl's name!"
    • Dimetro is kind of an oddball here. Dimetrodonts are most definitely not dinosaurs. They are pelycosaurs, the ancestors of the therapsids, who were in turn the ancestors of mammals (in short, Dimetro is a closer relative of the Secret Scouts than he is to any of the Dinosaucers). However, given Dimetro's appearance, it's very possible that the producers had Dimetrodon confused with Spinosaurus. Old illustrations of Spinosaurus show an animal that could easily be confused for a bipedal Dimetrodon (the only good specimen of Spinosaurus was destroyed during World War II — really). Indeed, Dimetro's head resembles the head Spinosaurus was drawn with in the 1980s, long before Spinosaurus' relative Baryonyx was discovered and turned out to have a head that does not look like that of any other large theropod at all. Take a look at this old illustration from the time (there's even a direct comparison to Dimetrodon) for an example. Oddly, the show's broad definition of "dinosaur" would actually prove a boon decades later, as one of their number was an Archaeopteryx, which is now classified as a dinosaur.
  • But in the darkest depths lurks Dino Squad. It's the tale of a pair of (nekkid) Velociraptors who hide from the (instantaneous Kill 'em All style) extinction in a cave. And they live in that cave for well over sixty million years. (Yeah...) Finally, they emerge into the modern world with psychic powers, including the convenient ability to pass as humans. The bad 'raptor becomes a Corrupt Corporate Executive who wishes to use some kind of chemical to "return the animals of the world to the creatures they once were: DINOSAURS!" The good 'raptor poses as a teacher, and in this position, she is able to mentor the ragtag bunch of teenagers who are affected by the bad 'raptor's chemicals, allowing them to transform into the usual dinosaur suspects. For his first experiment, the bad 'raptor uses the stuff to "revert" a shark into what everyone on the show insists on calling a "Mutated Megalodon" — except that it's a Tylosaur, an ocean-going lizard. If you know that neither of these animals are dinosaurs, that neither lizards nor sharks have anything to do with the dinosaur family tree at all and are both far, far more primitive families of animals, and that — you know — sharks aren't frikkin' lizards, give yourself a round of applause. You're smarter than the people paid to write this.
    • The show also stated that Spinosaurus' super power was super speed. Good luck estimating the top speed of a taxon known only from vertebrae and parts of the skull. And now considering 2014 discoveries of Spinosaurus, super speed is certainly out of the question.
    • The Styracosaurus in the show is depicted as having having two brow horns that are larger and longer than the nasal horn, when in reality, it should be reversed. What's worse is that the official website accurately states that the brow horns should be smaller. Of course, the official site made its own mistakes, such as stating that Tyrannosaurus dragged its tail along the ground like a kangaroo (and yet, the show got its posture right).
    • In one episode, Veloci attempts to infect the clouds with primordial ooze so it woud rain down on everything and infect everything, from plants to animals to insects, and how they would all become dinosaurs. Yes, even the plants. And this is coming from a guy who came from the Cretaceous and is a dinosaur himself.
  • Transformers: Beast Wars is okay in terms of accuracy. Megatron, Terrorsaur, and Dinobot turn into a Tyrannosaurus rex, a Ptero Soarer, and some kind of Velociraptor or Utahraptor respectively, but they get their alt modes by scanning fossils rather than living creatures. Then again, all three were found around an area filled with lava and volcanic rock, which would normally destroy fossils.
    • Magmatron from the Japanese Beast Wars series is a multi-component transformer who consists of a Giganotosaurus, a Quetzalcoatlus, and an Elasmosaurus. The Beast Wars Sourcebook, which adapts the characters for American continuity, apparently didn't get the memo, as they say the three have "only loose connections to actual reptilian lifeforms." To be fair to the sourcebook, the models really do only resemble the aforementioned animals loosely: the Giga model is a generic-as-it-gets theropod, the Plesio has an incredibly bendy neck (though this can be forgiven, as it's needed for the transformation) and a lizardlike head with incorrect eye-placement, whereas the Quetz looks like a scaly vulture with a huge, serrated beak.
    • Speaking of Magmatron, the series contains an assortment of dinosaurs as alternate modes for the various villain characters. Most of them were excellent in terms of accuracy, at least for their time... save for Hardhead, who was a remold of Beast Wars Dinobot and was a Pachycephalosaurus with a jaw full of razor sharp teeth and the toe talons of a Velociraptor. Pachys were herbivores, or omnivores at best.
      • The original raptor mold wasn't without its problems either. Besides looking like a JP raptor, it had six digits on its back feet, creating Dinobot's trademark double-thumbs. It should only have had four. When an upgraded version of the figure was released for the Classics/Universe toyline, it looked a lot closer to the character's cartoon depiction. But it still suffered from inaccuracies: it had a bent tail, pronated hands and scaly skin (in 2008!), in a line that was meant to recreate old characters in updated alternate modes. But at least the new toy did away with the original's spinning shield gimmick, a feature that required the figure to have an elongated button sticking out of its cloaca that you had to push in repeatedly. Yuck.
    • Transformers G1 had the Dinobots as how the dinosaurs were popularly thought of at the time: Grimlock was tripod-stanced, Sludge had a swan neck and dragged his tail, Snarl was extremely hunchbacked. Fortunately the Dinobots were much more realistically done in Transformers Animated, Grimlock especially.
    • G1 also had the two-parter titled Dinobot Island, where they met horrible depictions of living prehistoric animals. Tail-dragging, Godzilla-sized Theropods, a pterosaur (looking a lot like the relatively small Dimorphodon) lifting Spike up to her nest (filled with eggs bigger then the mother), a bendy-necked plesiosaur (also being able to pick up Spike). And it was written by Donald F. Glut, renowned paleo-expert! Though considering he hated working on the cartoon, it is not unreasonable to assume that he did make himself cry while writing it.
  • The Jimmy Neutron series was guilty of this in several episodes.
    • The pilot movie had Cindy giving a presentation on a raptor-like dinosaur, using a model skeleton as a visual aide... and she refers to it as a plesiosaurus, which, to make matters worse, wasn't even a dinosaur. Somewhat subverted when Jimmy calls her out on it, but he manages to uphold the trope by claiming that the dinosaur was in fact a Megalosaurus, which it looked absolutely nothing like.
    • Then there's "200 million years ago" = "the late Cretaceous era" ... and all of the issues THAT brings up. In the same episode, there are Pteranodon that use their feet like talons, plus the giant Pteranodon eggs. A later aired TV special corrects this and puts the late Cretaceous 75 million years ago. However, they still featured a T. rex, which did not evolve until 7 million years later.
    • Another episode had a Jurassic Park-styled Velociraptor.
  • Played painfully straight in the Stanley Direct-to-Video movie Stanley's Dinosaur Round-Up. After jumping into the Great Big Book of Everything, Stanley encounters a herd of Brachiosaurus, which soon run off, scared by a three-fingered kangaroo-stance Tyrannosaurus rex that appears to be bigger than the brachiosaurids. Brachiosaurids did not travel in large herds (they would have stripped large areas of their foliage too quickly), they went extinct about 70 million years before tyrannosaurids evolved,note  they couldn't run nearly as fast as they did in the show, tyrannosaurs held their bodies horizontal to the ground, had two fingers per hand and were considerably smaller than Brachiosaurus. Stanley is usually intended to be educational.
  • Dinosaur Train on PBS Kids tends to avert this by having Dr. Scott the paleontologist come in and explain what scientists believe (and an un-named, party-pooper character step in and complain about one of the most fantastical moments in the episode like "Point of fact. Dinosaurs did NOT give music concerts."). That's not to say, however, that it's completely immune to some very odd mistakes (ectothermic pterosaurs, anyone?).
  • One episode of Chip 'n Dale Rescue Rangers show that some dinosaurs from the Late Jurassic Period actually came from outer space and are really small and intelligent but Earth's food made them grew big and stupid.
    • Even though he's an alien, Steggy's anatomy is completely wrong for a Stegosaurus: he has a dragging tail, a low-slung body, stubby limbs, grasping paws with four claws on each, an alligator belly, plates that look like half circles, a long serpentine neck, and a lizard-like head with lips. Stegosaurus had elevated tails, graceful frames like an elephant, long sturdy legs, hoofed feet that were completely incapable of grabbing, two claws on each forefeet note , chainmail-like skin (according to a layer of small bones found underneath the neck), pentagonal plates, short yet mobile necks, and horse-like heads with a beak.
      • Not to mention Steggy can also run fast and casually ROLL OVER ON HIS SIDE. Even a layman knows these are impossible for a stegosaur.
      • On the other hand, he is depicted as being able to stand on his hind legs. The problem is that he can walk on them most of the time.
      • Pretty much all the dinosaurs in the episode are anatomically inaccurate. In fact, they look no different than the swamp-dwelling, slender-limbed, tail-dragging dinosaurs from portrayals in the early 1900s (like this for example).
    • The episode also went with the "dinosaur eggs are gigantic" myth (although the "egg" featured was really a spaceship).
  • Phineas and Ferb tend to run headlong into this trope whenever their daily shenanigans bring them in contact with dinosaurs. For example, the episode where the boys (and Candace) travel back in time, they encounter sauropods wading in swamps (an idea that has been disproven since the fifties) and has a Tyrannosaurus rex with three fingers. They say they went back over three hundred million years. Three hundred million years, huh?
    Phineas: Hey T. rex, aren't you a little young to be hanging around in the Carboniferous?
    • This trope is played straight again in the episode "Lizard Whisperer", where the boys' American chameleon (which is a whole other trope in and of itself) is enlarged to gigantic sizes, and the boys call it a dinosaur. This one, however, is lampshaded.
    • A third instance of this trope occurs when Perry the Platypus fights Doofenshmirtz in Hawaii over the "Devolvinator". When the Devolvinator's beam hits Perry and Doofenshmirtz, Perry devolves into, among other things, an Ichthyornis and a Triceratops. What? Platypodes aren't even remotely close to either of these extinct organisms. Don't the creators even listen to their own song, he's a semi-aquatic mammal of action.
      • Given how Doofenshmirtz's evolutionary stages weren't exactly accurate either and got a giant ear in one of them ("Okay, this I don't even get."), it might have been Played for Laughs. Also probably justified as "Brain Drain" suggests that Doofenshmirtz himself doesn't know what evolution actually is, only that it is "something to do with monkeys".
    • Fortunately, the creators decided not to add dinosaurs in an episode that is set in the Stone Age and has the main cast as cavemen.
    • Averted in "Boyfriend from 27,000 BC", which showed frozen prehistoric animals representing the time periods they're from (Stegosaurus for Jurassic, Pteranodon for Cretaceous, a mammoth for Pleistocene, and a neanderthal for Paleolithic).
  • Dino Riders operates on the Rule of Cool, and so features several strange elements. All flying reptiles are able to carry humans on their backs with no problem (this is notably impossible, especially for Pteranodon), and both Pteranodon and Quetzalcoatlus are the same size. The heroes and villains fight over a Brontosaurus (which is also dubbed as the biggest dinosaur) and not an Apatosaurus. In the toys, virtually all of the ceratopsians are identical in size (and Kentrosaurus was as large as Stegosaurus). Despite this explicitly taking place on Earth, all the dinosaurs are shown living in the same time period (i.e. Cretaceous, Jurassic and Triassic creatures all existing simultaneously). And then the Ice Age mammals and cavemen start showing up.
  • Mighty Max, with its paranormal story lines, had to oblige us with a dinosaur themed episode. An Evilutionary Biologist used a de-evolution machine to turn lizards into dinosaurs. Despite lizards and dinosaurs having some similar features, these two groups are not all that closely related, never mind being descended from each other. Interestingly enough, the de-evolving beam was used on sapient chicken ("Fowl, actually.") Virgil. Even though Virgil should have become a theropod dinosaur, he becomes a pterosaur instead. Pterosaurs are not true dinosaurs, nor are they the ancestors of birds.
  • The New Adventures of Superman episode "Prehistoric Pterodactyls". Did you know that pterodactyls (actually depicted as impossibly large Pteranodons) can catch fighter jets in their mouths, survive direct hits from missiles and naval gunfire, go one-on-one with Superman and survive in space? According to this episode they can!
  • According to the Jonny Quest TOS episode "Turu The Terrible", pteranodons are much larger than human beings, can fly while carry a human being in their talons, and survive multiple direct hits by bazooka rounds.
  • In the Johnny Test episode "Johnny BC", the sister's teacher makes them look for a fossil from precambrian times, so the sisters go back to caveman times for a 3-toed sloth fossil to plant where they were looking. Too bad precambrian times ended 540 million years before cavemen appeared.
  • The Batman Beyond two-parter "Curse of the Kobra" involves the KOBRA organisation's attempts to gene-splice themselves into a dinosaur-human hybrid race that will rule the world. Their plans include detonating a nuclear warhead in a dormant volcano, with the resulting eruptions raising the global temperature. Why? Because everyone knows dinosaurs are cold-blooded, and can't survive let alone function in less than tropical climates. The spliced Big Bad even weakens and collapses as soon as his climate-controlled environment is breached.
  • Gertie the Dinosaur one of the earliest cartoons ever made features Gertie alongside a mammoth. She also eats far more material than her body could hold such as a tree twice her size and drinking A LAKE which scenes are there mostly for Rule of Funny.
  • Strangely averted in the DuckTales episode "Marking Time", when Scrooge literally travels back to One Million B.C. to find a land in which caveducks coexisted with dinosaurs. That seems bad, until you remember that dinosaurs did coexist with several types of modern-style birds, including ducks. That in turn implies that the Duck Universe takes place in the Paleocene, which would make sense, since that was a time dominated by six-foot birds.
  • I'm A Dinosaur. Holy sweet mother of John H. Ostrom, I'm A Dinosaur. For a cartoon that tries to be educational, it fails pretty spectacularly at being such. For instance:
    • Brachiosaurids with long, diplodocid-like tails (yeah, have fun with that).
    • Boatloads of Anachronism Stew & Misplaced Wildlife (for instance, the Late Jurassic Compsognathus in the Early Cretaceous and the African Jobaria in South America).
    • Sinosauropteryx with the largest theropod tail (the creature itself was turkey-sized, making this impossible, although this is true if it's proportionate length).
    • Giganotosaurus note  as the largest theropod (Spinosaurus was known to be larger for some time then).
    • Dilophosaurus as the largest Jurassic theropod (ironically, the show features Allosaurus and did an episode on the considerably larger Torvosaurus).
      • They probably meant the largest Early Jurassic theropod, and Dilophosaurus did rival Cryolophosaurus and the ichnotaxon Eubrontes for that title.
    • Abelisaurid hands proportioned liked those of typical theropods. They were ridiculously tiny, without elbows or knuckles.
    • Saltopus as a dinosaur (generally considered a more primitive dinosauromorph since the Turn of the Millennium).
    • An "Ultrasauros" character (it had been sunk into Supersaurus for some time then).
    • Egg-laying plesiosaurs (live-birthing plesiosaurs were still a pretty recent discovery then, but they still should've known better).
    • Three-fingered tyrannosaurids (any competent paleontologist could tell you this is wrong).
    • Deinonychosaurian Megaraptor (disproved in 2003, well before the series' 2009 pilot).
    • Inaccurately feathered maniraptorans (do we really need to review this?)
    • The implication that theropods were the only bipedal dinosaurs (primitive members of all dinosaur groups could walk bipedally, and the most advanced ornithopods retained this feature to an extent).
    • Zuniceratops with a nose horn and being the earliest ceratopsian (its lack of one is the only difference a layman could find between it and a chasmosaurine ceratopsid, and if you're discussing a taxon as obscure as Zuniceratops, there's no excuse for you to not know Psittacosaurus at the very least).
    • Blatant mispronunciations of multiple names, such as Sinornithoidesnote , Sinosauropteryxnote  and Carcharodontosaurusnote .
    • Feathered, bipedal pterosaurs that perch in trees and have 2 small fingers.
    • Bavarisaurus as a small feathered theropod dinosaur (it was a lizard).
    • Sauropods, hadrosaurs, ceratopsians, and thyreophoreans with the wrong hands.
    • Velociraptor with an Allosaurus-like skull.
      • Similarly, Allosaurus and Giganotosaurus have skulls shaped like those of large tyrannosauroids than actual carnosaurs.
    • Smilodon with a long, Panthera-like tail.
    • Stegosaurus with a toothed beak and 8 plates arranged in pairs.
    • Herrerasaurus described as being the size of an elephant. The only herrerasaur that big was the putative "Aliwalia", which appears to be a sauropod relative anyway.
  • The eponymous Denver the Last Dinosaur doesn't seem to belong to any known species.
  • The Nick Jr show Bubble Guppies did an episode on dinosaurs....thing is they included Pterosaurus and Marine Reptiles as dinosaurs. This is supposed to be educational. To be fair, they did go out of their way to use Apatosaurus instead of "Brontosaurus".
  • The Animated Adaptation of the Belgian action-adventure comic series Bob Morane had an episode dealing with Time Travel. Naturally, all of the creatures the characters meet are Jurassic Park-inspired, down to the frilled Dilophosaurus, which is also misplaced in time to the Late Cretaceous (actually lived in the Early Jurassic, almost 150 million years earlier), but at least they got its size right. The episode also has stampeding "raptors", and mountain-sized dino skeletons that the heroes use as bridges to cross a quicksand swamp]].
  • An episode of The Little Mermaid TV series either didn't care or just figured "We already have a mermaid using a magic trident, screw it" (so brace yourself) when everyone takes a trip to the Arctic (the mermaid equivalent of Aspen apparently) where Ariel sees the "poor frozen dinosaurs" and decides to thaw them out with good ol' King Triton's trident. It starts off all well and good with the land-based herbivores peacefully cavorting with Ariel UNDERWATER before the mean ol' T. rex starts chasing them... UNDERWATER. Without needing to come up for air. In the ARCTIC WATER. Everything is set right again with the dinosaurs' previously frozen home melting and restored back to its former glory like just another day in the life for Atlanteans on vacation though the audience will either be confused from this trope enough to fail any tests in school, angry at the severe logical fails (because cartoons about mermaid princesses and magic tridents are "so" logical) or just laughing at the sheer audacity of a mermaid being hunted by a T. rex.
  • According to one episode of I Am Weasel, the earth was flat during the Mesozoic and that dinosaurs died because they laughed at I. R. Baboon's red butt and fell off the flat earth. Given the show's setting, this is none too unusual.
    • And then there's the caveman-themed episode (dinosaurs included).
  • The Flintstones: Dinosaurs are shown coexisting with humans: mammals that existed up through the Cretaceous were small and rodent-like. That hardly matters.
  • Arthur
    • The title card for the episode "Sue Ellen & The Brainasaurus" misspells "-saurus" as "-saurous".
    • The episode "In My Africa" mentions dinosaur bones found in Angola… accompanied by a photograph of a mosasaur skull.
  • In the Rugrats episode "Reptar 2010", the main characters watch a Reptar movie that claims dinosaurs ruled the earth fifty thousand years ago. FIFTY THOUSAND.
    • Possibly justified since Reptar is a Godzilla expy, a franchise that isn't exactly known for scientific accuracy. The real clincher was an episode where the protagonists visit a museum and learn that T. rex is from the Jurassic. They're at least 80 million years off.
  • Having been made in 1979, the pilot episode of the French Edutainment cartoon Il était une fois... l'Homme (Once Upon a Time... Man) gets a free pass in most respects, but it's still odd how the animation shows birds descending from non-dinosaurian thecodonts and yet the narrator insists later on that they've (along with crocodiles) also evolved from dinosaurs.
  • The caveman episode of Goof Troop. Perhaps the biggest offender is that what looks like an outdated representation of a carnivorous theropod was referred to as a Brontosaurus. Interestingly, while the creature in question was shown eating meat, Goofy points out that Brontosaurus were herbivores.
  • The "Scary Monsters" episode of Timothy Goes to School perpetrates old, debunked claims like carnosaurian-looking Velociraptor and pterosaurs that hang upside-down like bats (although some things, like sauropod nostrils being on top of the skull, are actually Science Marches On).
    • Not to mention that Megazostrodon is called a dinosaur (it was a primitive mammaliaform), and the model shown looks nothing like the real animal.
  • The Fairly Oddparents often depicts Tyrannosaurus rex with a kangaroo-stance. Strangely, they got it right in the opening of Abra-Catastrophe with Wanda's T. rex form.
    • Not to mention there's scaly, bat-winged pterosaurs and sauropods with crocodilian belly-scales. A more recent episode had dinosaurs living with cavemen in 50,000 BC.
    • Given the nature of the show, however, these inaccuracies hardly seem out of place.
  • Lampshaded in an episode of Ed, Edd 'n' Eddy which involved one of the Eds' scams as taking the kids back in time to the Triassic Period, and they use Triceratops and Tyrannosaurus as the fake dinosaurs to terrorize the kids. Double D found this amusing, since these dinosaurs were actually from the Cretaceous.
  • This occurs in Dingo Pictures' "Dinosaur Adventure" because of laziness and a desire to reuse animation from one of the studio's previous movies. The main character and his parents are clearly members of different species, herbivores can become carnivores, and animals from the Age of Mammals coexist with dinosaurs.

    Real Life: Creationism 
  • Several Creation Museums exist throughout the United States, containing exhibits that depict what their creators claim is a strictly literal Biblical account of the origins of the world.
    • Dinosaur Adventure Land in Florida had several exhibits illustrating how, as the Earth is only 6,100+ /- years old "according to the Bible," not only did humans and dinosaurs coexist; but humans (set up by God as having dominion over other animals) must have domesticated them - AND rode them like horses!
    • The AiG Creation Museum is a lot more careful with this issue. They merely state that man and dinosaur lived in peace before Adam's fall and that after the Flood, dinosaurs went extinct at different rates, pointing out how 1) a postdiluvian world would have rapid climate change due to rapid alteration of the geological landscape by being buried under a mile and a half of water, 2) the term "dinosaur" didn't exist until 1841 and 3) the line between what was considered a mere reptile by ancients and what was considered a "dragon" varied widely by ancient culture. As for the whole "domesticated them like horses" part, they are careful not to make that claim explicitly.
  • About every paleontology-related item here. Some that stand out:
    • Some scientists found a hadrosaur skeleton with preserved, scaly skin, and garfish and turtles nearby. Thus, as that site says, he wasn't a bird ancestor, and must have died in the great flood. First of all, hadrosaurs WEREN'T bird ancestors. If it's because they both have beaks, that's like saying octopi and squids were bird ancestors! Secondly, a minor flood could have mixed up the fossils, or it slumped over dead in a lake or river.
    • There are gaps in the fossil record. Here are examples, with the link referring to a fossil that proves it false: fish and amphibians, amphibians and reptiles, reptiles and birds, reptiles and mammals (note that mammals did not descend from actual reptiles, but basal synapsids), and land mammals and whales.
  • Dinosaurs living alongside humans is also featured in this sarcastic Teach the Controversy T-shirt.
    Real Life: Pseudoscience 

  • The "Paleolithic" Diet, which claims to be the healthiest diet due to supposedly being based on what our ancestors ate during the bloody ice ages. The problems inherent within this claim are numerous:
    • Human diet was incredibly varied even then. Depending on the climate, early man would eat either nothing but fruit and possibly fish, or nothing but meat and the occasional root.
    • The plan makes the false assumption that modern humans are genetically identical to their stone-age ancestors, ignoring modern evolutionary theory. The prevalence of lactose tolerance among African, European, and West- and South-Asian adults; lactose tolerance is only useful if you've domesticated the cow—currently believed to have happened around 7000 BC—and herd them in a big way (which East Asians as a rule did not do, preferring to use them as beasts of burden).note  The human digestive system was remarkably more tolerant of microbes than ours are today. Remember, the cleanest thing those guys would eat from was their bare hands. If we would try that today, a great deal of us would get a nasty case of food poisoning.
    • From the linked website, every single recipe involves some sort of minute preparation (spices, minced vegetables, olive oil) that would have resulted in the death of any paleolithic human if they'd tried to dedicate their free time to acquiring it all. Look at all those vegetables. The recipes depend on having a steady variety of plant and fruit products (and their variety of nutrients) which far exceeds the range available to any prehistoric human, and many fruits and vegetables we eat today are only viable as meals because extensive farming resulted in their growing to five times their original size. Somewhere around a quarter of those recipes involve tomatoes, which until their domestication were native only to South America (which had a human population of 0 until the tail end of the Paleolithic).
    • Perhaps most importantly, what paleolithic people ate is in no way necessarily the ideal healthy diet for either humans in general or, more importantly, modern people who spend much of their time at keyboards and in chairs rather than hunting, fishing, and gathering from dawn to dusk.
    • Never mind that that food today is nothing like food that was available tens of thousands of years ago. There was no agriculture yet and therefore food plants did not provide many things modern humans would recognize as food.
  • This interpretation of an ichthyosaur bonebed. Instead of a bunch of ichthyosaurs dying from, you know, some plausible cause, according to this idea the ichthyosaurs were killed by a speculative giant squid that we have no evidence ever existed. What's more, it claims that the "giant squid" used the bones of the ichthyosaurs to create a self portrait.
  • In April 2012 the idea that large dinosaurs were aquatic resurfaced and gained immense attention from the press. Except whoever came up with this didn't give any actual reasoning and the few he implies don't have a leg to stand on.note 
  • David Peters' bizarre interpretations of pterosaur fossils, their life appearance, behavior and evolution. The modus operandi of Peters, an artist with no science background beyond illustrating some dinosaur books in the 1980s and 1990s, consists of scanning photographs of pterosaur fossils, applying Photoshop filters and tracing whatever "structures" emerge. Thanks to this, he claims to have found evidence that pterosaurs were bipedal and viviparous; had countless non-aerodinamic skin crests and wattles, and long, thin tails with tuffs at the end; and were actually not archosaurs but descendants of Triassic lizard-like reptile Longisquama (coincidentally a favorite "bird ancestor" of the BAND crowd). Peters gained special infamy in 2004, when two Chinese paleontologists published their study of a Jeholopterus' egg with a near-term embryo in its interior, the first conclusive evidence that pterosaurs laid eggs. Because this run against Peters' life-birth 'hypothesis' (based on the image of four pterosaur embryos inside their mother that nobody but him could see, obtained by applying photoshop filters just a few months before), Peters rushed to publish an article in the Prehistoric Times commercial magazine where he described the Jeholopterus egg as an adult anurognathid pterosaur that died while eating the content of a dinosaur egg, and even had the gall of naming this new "species" Avgodectes pseudembryon ("False embryo egg-biter"). Needless to say, this taxon name is invalid.
    • Additionally, pretty much every source he provides on his website links to something he himself wrote, unless he wants to refute something, of course.
    • He's also so prolific that a layman doing research online could easily fail to realize that his isn't the default view; this one man has basically drowned out the entire field with sheer volume.
    • Perhaps the most bizarre thing about Peters' "research" is the fact that he seems wholly ignorant to peer review. As in, he seems to not even know what it is; everytime he comes up with a new "finding", it seems to fall into the pattern of him posting it on his blog, expecting it to be instantly accepted as scientific fact and then being baffled as to why it isn't.
    • It gets worse. Peters' grasp of phylogenetics is nowhere near as firm as he likes to think it is. In particular, it appears he doesn't quite understand how to read phylogenetic tree diagrams. This has the result of him misinterpreting scientific literature and coming to mindboggling conclusions; he thinks that mainstream paleontology regards phytosaurs as the closest relatives to, if not the direct ancestors of, pterosaurs. Oy vey.
  • Pseudoscientist Danny Vendramini's infamous interpretation of neanderthals. According to him...
    • The reason we reconstruct neanderthals as looking like humans is due to anthropomorphic bias instead of, you know, neanderthals being a species (possibly even subspecies) of human, and thus would probably look extremely similar.
    • Neanderthal skulls are more similar to chimpanzee skulls than to human skulls. The illustration featured clearly shows that the neanderthal skull is out of line with the chimp's head. For one thing, the neanderthal's spine is coming out of the bottom of the skull instead of the back like with chimps, indicating an upright-walking creature.
    • Since neanderthals evolved in cold climates (Europe during the ice age), they should have a full body covering of fur. This ignores that there is evidence that neanderthals made clothing, and while they may have had more body hair than modern humans, there is no reason for them to have a shaggy coat.
    • Since there is little to no nutritious plant food in the area, they would be full-on predators. Even though we have plenty of evidence neanderthals ate plants as well as meat.
    • Since they (supposedly) hunted at night, they should have glowing red eyes with slit cat-like pupils. Never mind the fact that no primate alive today has slit pupils. (Not even nocturnal ones like owl monkeys and tarsiers.)
    • They were much larger than a human, and six times stronger than them. (Inconsistent with the usual evidence showing they were short and stocky compared to us.)
    • Since there is evidence that cro-magnons and neanderthals interbred, this means that neanderthals not only hunted humans for food, but also liked to rape them as well. Why would something so drastically different from a human in appearance want to bang them this much?
    • There was a period of 50,000 years in which neanderthals committed unspeakable acts of terror against cro-magnons. Scary humanoids in movies and stories are a result of an innate fear of neanderthals due to this event. Examples he gives in the above video include Darth Maul, Gollum, T-800, King Kong, and xenomorphs. Lets remember that NONE of these characters (especially the last one) resemble either the pseudoscientific or the actual neanderthals.
    • Humans' extinction of neanderthals is a brave and heroic act that saved our species from going extinct from these savage beasts. (It's more likely we were the ones terrorizing them.
    • All in all, Vendramini's hypothesis seems to be more based around Rule of Cool and Rule of Scary than actual scientific evidence. While he gives an explanation for the shaggy coat and cat-like eyes, he never explains the dark skin (Wouldn't lighter skin make more sense for a cold-dwelling beast? Also, we have evidence that neanderthals carry genes for both light skin and red hair.) or the flat, gorilla-like nose. (Evidence points to neanderthals having larger noses than modern humans, to help them breath better in the cold.) And in every single picture, his neanderthals are always snarling as if to show off what scary monsters they were.
  • In 2013, a small skeleton was found in a construction site in Corire, a town in Peru. The mayor promptly introduced it to the press as "Toñito", a "fossil fetus" of Velociraptor (a Northern Hemisphere dinosaur) and announced the construction of a museum devoted to its exhibition. The news got immediate scorn from paleontology enthusiasts in the Spanish speaking internet, because it was obvious that the skeleton was not fossilized and actually belonged to an adult mammal (it was later identified as an opossum).
  • Similar to the above; in mid-2016, a strange mummified animal (most likely a frozen mustelid) was discovered in a Jurassic-aged Siberian diamond mine. Rather than guessing the obvious-that the mammal had crawled into the mine and died there-the miners immediately assumed that it was a new species of dinosaur, and a few news agencies actually went along with their ideas! The stupid thing is that the animal was so well preserved that it retained all its mammalian features, meaning that no one should have mistook it for anything other than what it actually was.

    Real Life: Science 

  • Sometimes paleontologists make other paleontologists cry. One of the biggest debates between paleontologists recently was Jack Horner versus practically the rest of paleontology over whether or not Tyrannosaurus rex (and all other large theropods) were predators or scavengers. Horner was on the scavenger side, and uses arguments such as: The size of the animals is more conducive to scavenging (scare smaller animals from kills); their legs were designed for walking instead of running, and being so large any form of moving fast would endanger them by off-balancing their bodies; they can only use their mouths for attacking, which is dangerous; For T. rex specifically, the large olfactory lobe of the brain (meaning excellent smell) and the small size of the forelimbs (which prevented T. rex from holding prey with them), and the thick armor-piercing teeth and bone-crushing jaws (for breaking apart bones to get the marrow inside). The rest of paleontologynote  counters with:
    • As prey size increases, generally so does predator size. Every prey species has at least one predator that can take it down (at least at some point in its life).
    • The structure of the tyrannosaurid hindleg is similar to that of the ornithomimids, which were clearly cursorial.
    • Even if they couldn't run, the large theropods would have still had a brisk walking speed, and their prey wasn't designed for speed either, favoring either keen senses, armor and weapons, or herding for protection.
    • Many animals today use only their mouths to attack.
    • Tyrannosaurus also had binocular vision, a primary predatory adaptation. Many predators also use smell to track prey. The forelimbs of T. rex are also very heavily built with numerous strong muscle attachments, and they're designed to twist and pivot, which shows they could easily withstand the forces of struggling prey. As for the teeth and jaws, again modern predators show that bone-breaking isn't a scavenger-only tactic (hyenas, the master bone-breakers, hunt more than they scavenge; breaking bones allows them to extract more food from a kill).
    • Healed tyrannosaur bite marks have been found on Edmontosaurus and Triceratops bones. Since dead things don't heal, they must have escaped the tyrannosaur, showing that it actually hunted.
    • Finally, the only true vertebrate scavengers are buzzards, vultures and condors - creatures that can cover vast amounts of territory with a minimal amount of energy expenditure. No animal the size of Tyrannosaurus could live as an exclusive scavenger, as it would use too much energy searching for carrion. Tyrannosaurus also was the only large carnivore alive at its time and location, so if it wasn't killing large prey nothing was. And most predators are also scavengers. They'll take whatever food is on hand, which is a must for creatures that don't have a reliable and easy food source the way herbivores do.
    • Horner has acknowledged that Tyrannosaurus was an "opportunistic predator" (which is what everyone else thinks to begin with) in the only scientific paper he ever wrote on this subject. (Although he did popularize the scavenger hypothesis in books and TV shows.)
    • Note that the debate also runs on a False Dichotomy: scavenging OR predation. In practice, most carnivores like lions, hyenas and jackals do a bit of both.
  • The BAND (Birds Are Not Dinosaurs) crowd, who also go by several variants such as ABSURD (Anything But A Small Unidentified Running Dinosaur [is the ancestor of birds]), MANIAC (Maniraptors Are Not In Actuality Coelurosaurs) & RABID (Raptors Are Birds In Disguise), a group of so-called professionals (mostly physiologists & ornithologists who know more about modern birds than about extinct theropods) who cling to the idea that birds aren't dinosaurs as though it were their religion, even though such a "debate" should have ended more than twenty years ago. They're infamous for publishing papers making highly unsupported and unscientific excuses for why birds can't be dinosaurs (supposedly getting other BANDits to get them past peer review). Indeed, going by many of their arguments, nothing could evolve into birds and evolution shouldn't occur. (Note that the BANDits are not creationists.)

    The unfortunate side effect of this is that even though they're little more than laughing stock among the mainstream paleontological community, their vocality means that they often get coverage by journalists and creationists who don't know any better, misleading the general public that there is still a "debate" about whether birds are dinosaurs. In fact, in recent years most of them have no longer been able to deny the ever-growing evidence that birds are closely related to deinonychosaurs and oviraptorosaurs, and have changed their arguments from birds not being dinosaurs to all maniraptors not being dinosaurs (hence, MANIAC & RABID). Even David Peters (see below) is disgusted by them. There's also the fact that their claims about non-avian dinosaurs are occasionally somewhat at odds with our current knowledge about them. As Brian Switek, commenting on Alan Feduccia's book The Origin and Evolution of Birds, put it: "anything relating to dinosaurs being smart, active, or dynamic is discounted, Feduccia's model of dinosaurs more resembling the swamp-dwelling lizards thought up by early 20th century scientists (i.e. hadrosaurs are referred to as being primarily aquatic)". At least one BANDit supporter suggests birds evolved from pterosaurs (which is an old idea that was abandoned in the 1800s). They also resort to ad hominem and No True Scotsman arguments. A lot. Even individuals (usually laymen rather than scientists) who accept that birds came from dinosaurs tend to claim that "that doesn't mean that birds are dinosaurs"… evidently unaware of the fact that according to cladistics, that's exactly what it means. For comparison, it's for the same reason that humans are still apes—you never outgrow your ancestry.
  • American paleontologist Gregory Scott Paul often synonymizes dinosaurs that aren't especially closely related or are otherwise clearly distinct. His arguments come down to "these creatures seem similar" rather than any detailed similarities, much to the chagrin of other paleontologists.
    • On the flip side, renowned pterosaur expert Mark Witton has cast doubt on the reclassification of Pteranodon sternbergi to Geosternbergia sternbergi. He notes that while the two animals are different enough to be classed as separate species, they do not appear different enough to be separated on the genus level as well.
  • Every paleontologist makes at least one other paleontologist cry. Debates still rage about results, methods and data used, validity of the science, pet theories... and honestly, that helps keep research going. So, in a way, this trope isn't all bad.
  • Paleontology isn't that hot of a field all across the world, and in some countries, school textbooks are still written according to decade-old and thoroughly outdated scientific literature, simply because there aren't any recent publications in a given language that they could use as reference. Things like Brontosaurus still pop up from time to time in modern Biology books.
    • There exists a textbook still in use (in the USA, probably the most paleontologically-advanced country) that not only has featherless maniraptorans, but pronated hands abound, there's at least one tripod-stance Tyrannosaurus, the implication that birds may not be dinosaurs, and a Coelophysis with so wrong proportions, it is best labeled as a caricature.
  • In 2014, one scientist suggested that stegosaur plates, ceratopsian frills, hadrosaur crests and similar accessories evolved to deter parasitic deinonychosaurs from "riding" them (several living predators, such as wolverines and eagles, also "ride" their prey). The same author suggested that feathers evolved so that deinonychosaurs could jump from large prey and that some dinosaurs, such as stegosaurs, were driven to extinction by these predators. There are several big problems with this theory:
    • It's unlikely that small-to-medium deinonychosaurs attacked such large prey; it's equivalent to a lone jackal attacking an elephant.
    • Living animals that are "ridden" by predators do fine without plates, frills and whatnot. And most of those that do have unusual headgear and such are not specialized for using those structures to dislodge attackers.
    • The first dinosaurs to develop actual bird-style feathers were herbivores (or omnivores that fed on plants and small animals) that would have no need to interact with such formidable beasts.
    • It is ecologically unsustainable for predators and parasites to hunt their prey into extinction (the majority of cases that this has happened have been caused by invasive species), as that would be counterintuitive to their own survival.
    • Some of the suggested analogies in the publication (e.g.: eagles and wolverines) are not parasites.
  • Miller's "bulldog Smilodon" of the 1960s, an alternative reconstruction of saber-toothed cats. It disregarded most cat-like "soft" features, arguing that sabertooths separated from other cats too early to have them; gave them a short, retracted nose, based on the short length of the nasal bones, and a longer, more posterior opening mouth similar to a dog, claiming that it was necessary to produce the gape required to use the sabers. It was never popular, but it was mentioned as a possibility in the literature for three decades before someone decided to re-examine the evidence and write a rebuttal. It found that 1) many of the contested cat-like features are also present in viverrids, who branched out before sabertooths did, therefore sabertooths most likely had them; 2) Smilodon's nasals are no shorter than big cat nasals, who have short nasals yet long cartilage structures in their noses; 3) not only are living big cats capable of gaping as much as Miller though Smilodon needed to, but 4) the opening of the mouth in dogs is not actually more posterior than in cats. The mouth is longer in dogs because the snout before it is.
  • Bruhathkayosaurus. Despite what many internet lists of largest dinosaurs ever would lead you to believe, the first (and only) published article on Bruhathkayosaurus doesn't identify it as a sauropod, but a theropod, and doesn't offer any estimation of its size. The ideas that it was a titanosaur and possibly the largest dinosaur ever are unpublished second-guesses by other paleontologists based on the measures claimed by Yadagiri and Ayyasami in the original article, which has rather crude drawings and few text and photographs. Judging by these photographs, some doubt that the measures are correct, that all fossil bones belong to the same animal, or even that they are animal bones at all: the purported tibia has been at times identified as a piece of petrified wood. In any case the fossils can't be examined again because they were not fully extracted in time from the rock bed and were washed away during a moonsoon flood and lost. Even if Bruhathkayosaurus was real, it would also be the perfect example of how not to study a fossil.
