Theropods in general

• Animals Not to Scale: Many are depicted as far larger or smaller than they would have been in real life. In the case of being too small, this is sometimes been justified by the individuals as not fully grown.
• Artistic License – Paleontology: As per usual of the franchise artistic liberties are taken:
  • All of the theropods possess palates and tongues that are too mammalian in musculature. Given that they are closer related to lepidosaurs than mammals their oral tissue should instead resemble them.
  • Every theropod until Dominion was portrayed to have pronated wrists (wrists that can rotate) and arms held in front, when all theropods were incapable of this.
  • Many are depicted with the wrong anatomy, skin textures, or type of integument for the species they are based on.
• Carnivores Are Mean: Downplayed. Many of the theropods are meat-eaters that are only aggressive when they are hungry, being territorial, protecting their young, or are simply pissed by the presence of certain individuals.
• Informed Species: Quite a few animals have appearances that make them look like close relatives rather than the animals they are referred to as.
• Lightning Bruiser: Several of them are capable of keeping pace with or out speeding moving vehicles while taking absurd amounts of punishment that should kill them.
• Made of Iron: Many are shown to be capable of withstanding multiple injuries that should be lethal.
• Prehistoric Monster: Several of them are depicted as hyper-intelligent murderous monsters rather than animals. Sometimes, it's justified as many of their caretakers want their carnivores to be hyper-aggressive for entertainment or military purposes.
• Super-Persistent Predator: All of the carnivorous dinosaurs and even the Therizinosaurus are depicted relentlessly chasing down humans and other dinosaurs despite encountering distractions, barriers, or injuries that should slow them down at best.

Coelurosauria

Maniraptoriformes

Gallimimus

Gallimimus

Appearances: Jurassic Park | The Lost World: Jurassic Park | Jurassic World | The Evolution Of Claire | Jurassic World: Fallen Kingdom | Jurassic World: Camp Cretaceous | Jurassic World Dominion

"Gallimimus doesn't have a single tooth in its entire mouth."

— Jurassic World website

An ornithomimid or ostrich-like dinosaur bred for Jurassic Park and kept on both Isla Nublar and Sorna before they both fell. The species would later be brought back for Jurassic World with babies found in the Gentle Giants Petting Zoo and the adults in Gallimimus Valley. After the fall of the park and the island's volcano began erupting, many of them were captured and released into California.

---

• Accidental Hero: The Gallimimus flock may have unintentionally saved Grant and the kids who were standing out in the open when they forced the three to take cover behind a tree trunk to avoid being trampled moments before the park's Tyrannosaurus rex comes bursting through the tree line.
• Adaptation Dye-Job: The juveniles in Jurassic Park had horizontal stripes, whilst the juveniles in Jurassic World had a coloration identical to the adults.
• Adaptational Early Appearance: They appear in the first Jurassic Park film despite not being in the first book. They do show up in the second.
• Adaptational Species Change: The stampede scene involved Hadrosaurus in the book.
• Animal Stampede: Flocks of Gallimimus are almost always involved in the films' stampede scenes.
• Artistic License – Paleontology:
  • Being an ornithomimid, it should be covered in feathers and also has to possess wings and rectrices.
  • The lack of feathers in the film version notwithstanding, the LEGO version is just a generic theropod that looks nothing like a Gallimimus. Especially jarring considering the LEGO Jurassic World version greatly resembles the Gallimimus in the films. A later set, however, features a new Gallimimus figure that looks more like the film version.
  • A lot of Jurassic Park video games and novels labeled Gallimimus as herbivores. Gallimimus, along with other ornithomimids, are believed to have eaten small animals, insects, and eggs in addition to plants (though it's thought that plants would indeed have made up the bulk of their diet). The Jurassic World website, however, corrected them as being omnivores.
  • The Gallimimus in Camp Cretaceous are jarringly depicted with flat molars, something that was not even present in the films.
• The Bus Came Back: Gallimimus are absent in Jurassic Park III before making their return in Jurassic World, 18 years since their previous appearance in The Lost World: Jurassic Park.
• Continuity Nod: Their cameo in Jurassic World was filmed in the same area as the Gallimimus scene from the original film.
• Crippling Overspecialization: They're among the fastest animals in the park, but have no other way to defend themselves if they're attacked by larger, fiercer dinosaurs.
• Fragile Speedster: One of the fastest dinosaurs in the park, but beyond that have no real defenses against predators. As the first film shows, any predator that can go after them is usually capable of easily killing them.
• Funny Background Event: One of the first trailers for Jurassic World: Fallen Kingdom showing the stampede from the eruption has one not look where it's going and bump into an Allosaurus, much to the predator's annoyance. However, this is changed in the actual film to the ‘'Allosaurus'' snapping at it.
• Herbivores Are Friendly: Inverted. They are omnivorous, but their aggression level is listed as low. Their main tour location is a safari wherein people can ride alongside flocks of them as they run, and children are allowed to hold and pet the baby ones in the petting zoo.
• Informed Species: Downplayed. Its shorter body and skull shape make it look more like fellow ornithomimid Struthiomimus. The real Gallimimus had a longer skull and body.
• Long Neck: Though not exactly on the same level as Therizinosaurus and sauropods.
• Oh, Crap!: An interesting double-example; they invoke this reaction in Tim when they start "flocking [his] way"...and then it's implied that the reason they're flocking is that they themselves are having an Oh, Crap! moment being stalked by the T. rex.
• Red Shirt: One of them became breakfast for the T. rex.
• Ridiculously Cute Critter: The babies are tiny and adorable.
• Toothy Bird: A really weird and confusing example. The ones in the films have small teeth if you look closely, and the official website shows a picture of a toothed Gallimimus. And yet the website also claims that Gallimimus "doesn't have a single tooth in its mouth". So which is it? However, it's most likely the "teeth" on the film version are actually teeth-like tomia found in waterfowl.

Oviraptor

Oviraptor

Appearances: Jurassic World Dominion

A small, feathered maniraptor that appears in a Cretaceous flashback, raiding the nest of an unknown dinosaur. In the present, it was cloned for animal fights in the Amber Clave Market.

---

• Anachronistic Animal: The prologue of Dominion shows Oviraptor living 65 million years ago, even though the genus became extinct 70 million years ago.
• Animals Not to Scale: Averted. The Oviraptor in the Amber Clave Market is the same size as its real life counterpart, barely reaching the legs of adult humans. But thanks to paleomedia commonly using the emu-sized Citipati to represent Oviraptor (specifically the crest) and the fact that Oviraptor is depicted as a rival to Velociraptor, many viewers see the maniraptor as too tiny.
• Artistic License – Paleontology: It's a fairly accurate portrayal for the most part, but it has pronated wrists, is covered in hair-like feathers rather than contour feathers, and lacks the wings and rectrices the real animal had. Judging by related oviraptorids, its tail is likely too long as well (though to be fair, the tail of Oviraptor itself isn't preserved).
• Canon Immigrant: Oviraptor has appeared in several Jurassic Park games before debuting in Dominion.
• Cocky Rooster: An extended scene shows an Oviraptor being aggressive and tries to attack a Lystrosaurus in the Amber Clave Market like a rooster in a cockfight, only for the Lystrosaurus to swiftly decapitate the Oviraptor with a single bite.
• Evil Egg Eater: Subverted. It's shown to eat the eggs in a dinosaur nest, rather than brooding over its eggs like in the fossil records. But it lacks many stereotypes associated with an egg-stealing Oviraptor like snatching the egg with its claws or running from an angry mother. Instead, it behaves just like how a bird would behave if it stumbles upon an unattended nest full of nutritious eggs.
• Feathered Fiend:
  • Subverted since feeding on the eggs of other dinosaurs is part of its natural behavior.
  • Played straighter in an extended scene where one is actively shown fighting a Lystrosaurus in the Amber Clave Market before the latter decapitates it with a single bite.
• Informed Species: It has the tall-crested appearance more like its relative Citipati, which is atypical of media depictions of Oviraptor. But at least its size matches the real Oviraptor.
• Off with His Head!: The one in the Amber Clave Market gets decapitated by the Lystrosaurus it's supposed to be fighting.
• Shown Their Work: Minus the wings and rectrices, it's cloaked in a full coat of feathers, which we know to have been the case for oviraptorosaurs in Real Life. Its behavior and movements are very birdlike, particularly when it pins an egg with its foot and cracks the shell by pecking at it. The deleted scene where it fights the Lystrosaurus shows it is accurately sized, around the size of a real-life Velociraptor, rather than being the size of a man as in most portrayals.
• Stock Animal Diet: The name Oviraptor means "Egg Thief". Guess what we see it eating? Notably, it's been all but confirmed in Real Life that the holotype specimen of Oviraptor was a parent brooding the eggs it was preserved with, but of course, that doesn't rule out eggs as an occasional dietary supplement either.

Therizinosaurus

Therizinosaurus

Appearances: Jurassic World Dominion

A large, herbivorous, long-necked feathered theropod with long and huge claws cloned by Biosyn.

---

• Accidental Hero: It’s extremely territorial behaviour comes in handy when it joins the fray just in time to distract the Giganotosaurus before it could kill the protagonists or finish off an unconscious Rexy.
• Absurdly Sharp Claws: It has huge claws which are so sharp that it can perfectly impale the armoured Giganotosaurus on all six of its fingers just from the T. rex pushing the Giganotosaurus into its outstretched claws. There's also Audible Sharpness as this happens.
• Artistic License – Biology: As a large herbivore, the Therizinosaurus really shouldn't have cat-like slit eyes (which are normally only found in carnivorous animals that hunt low to the ground and in dim light like small cats, foxes, vipers, or crocodiles), other than to make it look more frightening and intimidating, despite being a plant-eater.
• Artistic License – Paleontology: Appears to have dewclaws. Real therizinosaurs had all four toes on the ground to better distribute their weight, highly unusual for theropods. Given its position within Maniraptora it should possess wing and tail feathers and have a body covered in a sparse coat of feathers rather than only having a thick coat of them on the back. It also has a more horizontal posture instead of a more vertical one it would have had in life, unique among theropods, and its potbelly^note which results from gastralia making it appear to have a potbellied profile. is less pronounced than it should be (therizinosaurs, being herbivores, required a much larger gut than carnivorous theropods in order to process tougher to digest vegetation). On the whole, its depiction looks more like a Gigantoraptor or at least an overgrown Falcarius than how an actual Therizinosaurus is thought to have appeared. Additionally, examinations of its claws indicate that the real animal only used them for display, being surprisingly fragile for their size, but this wasn't examined in depth until after produxtion had finished for the film.
• Canon Immigrant: Therizinosaurus has appeared in several Jurassic Park games before debuting in Dominion.
• Chekhov's Gunman: Appears in a short scene menacing Claire after she parachutes into the Biosyn dinosaur sanctuary, but it quickly loses interest and wanders off. It reappears at the very end when it unintentionally saves the protagonists by drawing the Giganotosaurus's attention, and then kills it, albeit mostly accidentally.
• Creepily Long Arms: The arms of the Therizinosaurus are among the longest of any living creature, and they are equipped with awe-inspiring claws.
• Early-Bird Cameo: Therizinosaurus DNA is used in the creation of the Indominus rex and the Indoraptor.
• Establishing Character Moment: It's first introduced menacing Claire after she crashed into its territory, only to lose interest when it sees a deer nearby. It swiftly kills said deer to get an easier spot to feed on some berries, before chasing after Claire when she escapes her seat, only leaving when something else distracts it. The scene establishes that the Therizinosaurus is a Xenophobic Herbivore and just how powerful it can be.
• Feathered Fiend: It is by far the largest feathered animal in the franchise, and probably the most aggressive herbivore ever portrayed.
• Fingore: It loses a chunk of one of the finger-talons on its left arm when the Giganotosaurus chomps down on it during their fight.
• Hair-Trigger Temper: It's extremely territorial to the point that it will kill a deer just for being in the way. When it sees the Giganotosaurus, it immediately attacks despite the Giga being the largest land predator in the sanctuary.
• Handicapped Badass: Its milky left eye and difficulty seeing Claire when she gets underwater imply it's partially blind, or at the very least has poor vision. Doesn't stop it from being in the top three most dangerous animals in Biosyn Valley or being the one that actually kills the resident alpha predator in the climax.
• Herbivores Are Friendly: Strongly averted. While the Therizinosaurus is one of the few purely herbivorous theropods, it is one of the most aggressive and territorial animals in the franchise. It casually kills a deer for no other grievance than standing in front of it then stalks and menaces Claire Dearing. Later on, it is very easily provoked into joining the fray between the Giganotosaurus and the Tyrannosaurus and as a result becomes the first and only herbivore in the franchise to kill a large carnivore.
• Humanlike Foot Anatomy: Inverted; it is depicted with typical theropod feet when the real animal was most likely plantigrade.
• Lean and Mean: It's the tallest and lankiest theropod featured in Dominion and it has a nasty territorial temper.
• Long Neck: Along with fellow Asian giant theropods Deinocheirus and Gigantoraptor, it has the longest neck of any known theropod. Judging by related therizinosaurs, the neck of the real animal may have been even longer than in the film.
• Mood Whiplash: It goes from fatally swatting aside a deer to peacefully nibbling on berries to stalking Claire through the forest.
• Predecessor Villain: Of sorts. Its species' genes went into the creation of the Indominus rex and the Indoraptor.
• Shown Their Work: Besides being a herbivore, it is depicted with a bird-like beak and plumage on its body. Its claws, while capable of slashing, are also quite effective as stabbing weapons, as per recent research.
• Single Specimen Species: It is the only known cloned member of it’s kind in the franchise.
• Summon Bigger Fish: Or rather summoning comparable-sized fish. Kayla provokes it into joining the battle against the Giganotosaurus to buy time so the group can escape.
• Tiny-Headed Behemoth: The small head of the Therizinosaurus rests high above its large body on top of its long neck.
• What Happened to the Mouse?: It disappears from the film after the Giganotosaurus dies, but as it is last seen roaring at Rexy and we later see Rexy alive and well, either they parted ways without incident or they fought with Rexy emerging the victor. Probably the former, since Rexy doesn't have any tell-tale scars on her.
• Wolverine Claws: The defining features of the species, and these claws are ENORMOUS, which shows that Therizinosaurus is not an example of Herbivores Are Friendly. The Giganotosaurus winds up impaled on them after Rexy throws it into them.
• Xenophobic Herbivore: It will attack anything that gets in its territory. The fact that it's seen feeding from a shrub and doesn't consume any of the animals it kills clearly mark it as this rather than Ascended to Carnivorism.

Dromaeosauridae

Dromaeosaurs in general

• Animals Not to Scale: Portrayed as large enough to look a grown human in the face. The real animals were all shorter than the human waist. Amusingly, the dromaeosaurs themselves are proportionally the same size as each other as they are in real life.
• Artistic License – Paleontology: They are all oversized, featherless^note except for the Pyroraptor, have feet that are oversized with huge pads, their sickle claws are too small, lack syndactyly in their hands, have skulls that abruptly end after the eye, scaly lizard-like faces, eyes too far forward in the socket, and possess reptilian slit pupils^note with the exception of the Sorna Velociraptors (real dromaeosaurs almost certainly had rounded pupils, owing to their close relationship to birds). The Jurassic World variants also have their teeth extending past the eye socket.
• Ax-Crazy: Tend to be depicted as savage beasts that will not waste an opportunity to brutalize their prey before killing them. They're also prone to acting on berserker tendencies whenever they spot something they can kill.
• Hellish Pupils: Practically a staple of this franchise's raptors.
• Informed Species: All of them look nothing like the species on which they are supposedly based.
• Lightning Bruiser: Fast enough to keep up with moving vehicles, while also being far stronger and more durable than they should be. Able to take a large amount of punishment and pain before they are killed.
• Prehistoric Monster: Consistently depicted as murderous monsters rather than animals, and their hyperintelligence makes them feel like psychopathic humans in dinosaur skin.
• Raptor Attack: They all look nothing like their real-life counterparts, being scaly^note except for the Pyroraptor, disproportionately larger than their real-life counterparts, and far smarter and more vicious than what they would have been in real life.

Atrociraptor

See Ghost, Panthera, Red, and Tiger

Pyroraptor

Pyroraptor

Appearances: Jurassic World Dominion

A semi-aquatic, feathered dromaeosaurid cloned by Biosyn.

---

• Animals Not to Scale: Standard with dromaeosaurs in the franchise at this point, it's much bigger than the real animal, which was even smaller than Velociraptor.
• Artistic License – Biology: Despite being semi-aquatic with its webbed feet indicating its status, the Pyroraptor lacks several features of semi-aquatic birds, such as the streamlined and waterproof feathers seen in cormorants and penguins. Likewise, its exposed head, legs, and stomach would lose heat quickly in a freezing environment, especially when in freezing waters.
• Artistic License – Paleontology:
  • Compared to the likes of Blue and the Atrociraptor it's fairly accurate, but still leaves some things to be desired. Its head, underbelly and legs are completely featherless when the entire body should have been covered in feathers, the pennaceous wing feathers attach to the wrist instead of the second digit on the hand, the head and hands are covered in scales and featherless, and its feet are webbed.
  • The Pyroraptor is portrayed as a semi-aquatic animal that readily swims in freezing water. While the real animal may have taken to island hopping and was likely to swim and maybe dive from time to time, the speed and way it swims is far less plausible; at best it would have been a mediocre swimmer.
• Breaking Old Trends: The first dromaeosaurid in the films to be depicted with feathers, thus subverting the franchise's deeply rooted history of Raptor Attack.
• Canon Immigrant: Pyroraptor has appeared in several Jurassic Park games before debuting in Dominion.
• Feathered Fiend: Complete with wings!
• Informed Species: In reality, Pyroraptor is very poorly known, so any reconstructions of the species have to be an amalgamation of generic dromaeosaur features, including this one. This version does not even retain the small size of the actual animal, so the only thing linking it to Pyroraptor specifically is its name.
• Ironic Name: Despite its name meaning "fire thief", it is an avid swimmer and is first shown in a cold area.
• I Work Alone: Unlike the other raptors in the franchise who are organized in packs and prefer to hunt with other individuals, the Pyroraptor seems to be a completely solitary hunter.
• Plot-Irrelevant Villain: It is a very aggressive hunter that does little to nothing to hinder Owen and Kayla’s progress.
• Raptor Attack: Downplayed in that it's the first reasonably accurate depiction of a dromaeosaurid in the franchise (design-wise at least), but it still sports a naked face, legs, and hands (with the wing feathers attaching to the wrong finger).
• Red Is Violent: The main coloration of its plumage is red and it is hostile towards Owen and Kayla.
• Shown Their Work: It is the first feathered dromaeosaur in the franchise (potentially explained by Ramsay mentioning that Biosyn's dinosaurs are "unaltered" animals that were made without using the DNA splicing that InGen had to rely on 30 years ago) and even has wings.
• Single Specimen Species: It is the only known cloned member of it’s kind in the franchise.
• Underground Monkey: A feathered, aquatic version of the raptors we're familiar with.

Velociraptor

See Velociraptor

Tyrannosauroidea

Moros intrepidus

Moros intrepidus

Appearances: Jurassic World Dominion

An early tyrannosaur theropod that appears in the flashback set in the Cretaceous Period, living around the Giganotosaurus and scavenging off its success. In the present, it was cloned by Biosyn for their sanctuary.

---

• Anachronistic Animal: The prologue of Dominion shows Moros living 65 million years ago, even though the genus became extinct 30 million years prior.
• Animals Not to Scale: The Moros featured in Dominion is much smaller than the real animal, being chicken-sized while the real animal was at least human-sized.
• Big Guy, Little Guy: It has a symbiotic relationship with the Giganotosaurus by behaving like a cleaner bird. The Moros gets a free meal by scavenging the meat stuck between the carnosaur's teeth.
• Canon Foreigner: Dominion is the official debut of Moros in the franchise.
• Feathered Fiend: While it may scavenge on scraps and morsels in the jaws of larger animals at times, it is just as willing to hunt live prey such as rodents. Subverted when a Moros is shown playing with a little girl near the end of Dominion without any sign of aggression.
• Killer Rabbit: While it certainly looks like a Goofy Feathered Dinosaur and you'd be forgiven to think that its a baby T rex. at first, it's also shown to be more than capable of taking down small prey. In the film, it is shown killing a mouse with ease.

Tarbosaurus

Tarbosaurus

Appearances: Jurassic World: Camp Cretaceous (Hidden Adventure)

A large tyrannosaur from late-Cretaceous Mongolia and a very close relative of Tyrannosaurus. At least one female was cloned on Isla Nublar and was present on the island in between the second and third seasons of Camp Cretaceous.

---

• Accidental Hero: She accidentally saved Darius by grabbing a Monolophosaurus and killing the smaller predator before it could attack him.
• Animals Not to Scale: Downplayed. The real animal was a large theropod but still slightly smaller than Tyrannosaurus. This one is as big as Rexy, who is huge even for a T. rex.
• Artistic License – Paleontology: The Tarbosaurus is basically a reskinned T. rex covered in croc-like osteoderms when it was in reality far leaner possessing a slimmer skull (ironically it actually appears to be slightly stockier than Rexy if you look closely, whereas the inverse would've been the case in Real Life). Being a tyrannosaurid there is evidence they lacked osteoderms instead being covered in small scales and possibly some light fluff.
• Canon Immigrant: It makes its debut in the Camp Cretaceous interactive special Hidden Adventure after not appearing in any of the films or other canon media.
• Divergent Character Evolution: The spikes down its back were invented for the show, but served to make it distinct from a Tyrannosaurus – which it otherwise very closely resembles.
• Filler Villain: The main recurring antagonist of the "Hidden Adventure" interactive episode that takes place between seasons 2 and 3, but given that she was never mentioned again afterward, she apparently didn’t make much of an impression on the campers even compared to Toro or the Baryonyx trio (especially once the Scorpios rex showed up).
• Informed Flaw: Darius (correctly ) described Tarbosaurus as being smaller than Tyrannosaurus, but when we see her actually measure up against Rexy they seem to be almost exactly the same size.
• Monster Is a Mommy: Introduced with a large clutch of eggs. Whether she's reproducing asexually or there's a second Tarbo is unknown.
• Multiple Endings: As she exclusively appears in the Hidden Adventure CYOA episode, her ultimate fate can be giving up on chasing the campers after they climb into the bunker, fighting and defeating Toro before retreating or being killed in a fight with Rexy. Considering she's never seen after this episode, it's likely that the latter was her canonical fate.
• Red and Black and Evil All Over: Well, maybe not "Evil", but it is a dangerous antagonistic predator with a distinct red-black hide.
• Remember the New Guy?: Tarbosaurus is not mentioned at all on the list of dinosaurs displayed at Jurassic World.
• Schrödinger's Cast: Due to Tarbosaurus making its first and only appearance in Hidden Adventure an interactive special which has multiple endIngs, some where it survives and others where it doesn’t. Its final canonical fate is up in the air.
• Shown Their Work: The Tarbosaurus is presented using her sense of smell as the main way she tracks the campers. It's been theorized that their sense of smell would be relatively more important to them than their vision as they had lesser binocular vision compared to Tyrannosaurus. She also seemingly has even smaller arms than Rexy which is also accurate, even if they are incorrectly pronated.
• Single Specimen Species: She is the only known cloned member of her kind in the franchise. It’s unclear if she laid her eggs asexually, if any of her eggs survived or if there were others on Isla Nublar or not.
• Spikes of Villainy: Has a few rows of short spikes running along its back.
• Super-Persistent Predator: She pursues the campers relentlessly throughout Hidden Adventure, a task for which her acute sense of smell comes in handy. It's implied that at least part of the reason for her relentlessness is having mistakenly assumed that Darius stole her eggs, due to having the scent of her nest on him for a while.
• Terrifying Tyrannosaur: Perhaps an even better example than most T. rexes in the franchise as she's only ever portrayed in an antagonistic light, although not on the same level as the hybrid theropods.
• Underground Monkey: Looks and acts essentially identical to the T. rex but with a row of osteoderms along her back (which are a speculative feature invented specifically to better distinguish her from her more famous cousin).
• What Happened to the Mouse?: It is unknown if any survived the events of Jurassic World: Fallen Kingdom.

Tyrannosaurus

Compsognathidae

Compsognathus

Compsognathus

"It gives me the creeps, like it's not scared."

Appearances: The Lost World: Jurassic Park | Jurassic Park III | Jurassic World: Fallen Kingdom | Jurassic World: Battle at Big Rock | Jurassic World: Camp Cretaceous | Jurassic World Dominion

A tiny dinosaur that travels in packs. The species was originally bred for Jurassic Park and kept on Isla Sorna and were later kept in Jurassic World. Many were captured and released into California after Nublar's volcano erupted.

---

• Adaptation Species Change: They were Procompsognathus in the books (and yes, there is a difference).
• Artistic License – Paleontology: A paleontologist in-universe identifies them as Compsognathus triassicus, but that's incorrect. It should be Compsognathus longipes, while the species name belongs to Procompsognathus (despite the similarity of their genus names, the two are not closely related). Also, there's no evidence to suggest they were the vicious pack hunters depicted in the films.
• Badass Adorable: Yes, these little guys are deadly too.
• The Bus Came Back: Compsognathus are absent in Jurassic World before making their return in Jurassic World: Fallen Kingdom, 17 years since their previous appearance in Jurassic Park III.
• Death by a Thousand Cuts: Encountering sheer numbers of them often leads to this.
• Demoted to Extra: Briefly appear in Jurassic Park 3, Fallen Kingdom, Battle at Big Rock, and Dominion, but do not have any major scenes.
• The Dog Bites Back: It is unwise to bully these small dinosaurs as they can retaliate in larger numbers, turning the hunter into the hunted, as Dieter finds out the hard way.
• The Dreaded: A mild case in Jurassic Park III. Just hearing a group of them chirping outside the tanker he and Grant are sheltering in is enough to get an Oh, Crap! reaction out of Eric and he immediately starts making sure that they can't get inside.
• Explosive Breeder: Implied—the Dino Tracker website explains that this is why they are one of the hardest species for the DPW to safely contain.
• Hero Killer: They come very close to being this in Jurassic World: Camp Cretaceous, preparing to make a meal out of Blue when she's trapped underneath an ACU vehicle and unable to escape or defend herself from them.
• Historical Badass Upgrade: The real-life Compsognathus was likely a solitary insect eater. Interestingly, though, the real-life Compsognathus was likely the apex predator of its territory.
• Historical Villain Upgrade: The real-life Compsognathus is believed to have been completely harmless to larger creatures. As already stated, they were likely the top predators of their biomes.
• Informed Attribute: In Jurassic World: Camp Cretaceous, they're said to have a venomous bite. Not only is this a nod to their novel counterparts, Procompsognathus—and yes it's a different species, no they aren't closely related—it explains how they were able to calmly stalk and eventually take down and consume prey the size of Dieter Stark. The viral marketing website for Jurassic World: Dominion also implies that the Compy is an Explosive Breeder as attempts to control their populations via trapping them have failed.
• Killer Rabbit: Tiny and adorable, but horrifically deadly.
• Non-Malicious Monster:
  • For instance, their attack on the little girl in the opening scene was mostly because she offered one of them food. Anyone who follows the rules of the wilderness will know why that's a bad idea...
  • And they attack Dieter just because he invaded their territory. They see him as a threat at first, since he'd shocked one of them on at least two occasions. And when he didn't leave their territory fast enough and went down, they weren't going to let all of that fresh meat go to waste.
• Remember the New Guy?: Compsognathus wasn't included on the list of dinosaurs featured in Jurassic World, but appears on Isla Nublar in Fallen Kingdom. Jurassic World: Camp Cretaceous establishes that they were present at the time of the first film.
• Ridiculously Cute Critter: Their small size and curious chirps almost make them cute, until they start killing people.
• Super-Persistent Predator: They're persistent when they choose their prey. Dieter Stark learns that the hard way when a pack of Compies swarm over him and start biting. Even when he manages to get them off of his body (and even strangle a few of them), the Compies don't retreat that far. They continue following Dieter until he collapses from exhaustion, too weak to fend off the next round of vicious (and this time, fatal) little bites. Again, it's implied that they may be venomous, which would explain why they're so confidently patient.
• Toxic Dinosaur: Not explicitly stated in the films but according to Jurassic World: Camp Cretaceous, the Compies have venomous bites, just like the Procompsognathus in the books. This would explain their calm demeanor when stalking Dieter Stark through the woods since they manage to get a few bites on him before being driven off. In Season 5, they kill Lana Molina by biting her legs to paralyze her before swarming en masse.
• What Happened to the Mouse?: Many Compsognathus were kept within the Amber Clave Market, but it's unknown what happened to them or the other prehistoric wildlife once the market fell into chaos.
• Zerg Rush: They kill larger, stronger animals with superior numbers and unrelenting attack rushes.

Non-Coelurosaurs

Allosauria

Allosaurus

Allosaurus

Appearances: Jurassic World: Fallen Kingdom | Jurassic World: Battle at Big Rock | Jurassic World Dominion

A large carnivorous dinosaur with brow horns and three-fingered hands. The species was initially bred for Jurassic World and lived there long after the park collapsed. Many were captured and released into the wilds of California once the island's volcano erupted.

---

• Animals Not to Scale: The adult in Jurassic World: Battle at Big Rock is positively enormous, in some shots appearing even larger than the Indominus. The real animal probably capped out at a bit over 30 feet long at maximum, a good deal smaller than Tyrannosaurus, and most specimens were much smaller. Downplayed in Jurassic World Dominion, where it still appears oversized but not outlandishly so (being similar in scale to its relative Saurophaganax, which may or may not be the same animal as Allosaurus).
• Artistic License – Paleontology: It is depicted with crocodilian skin and osteoderms on its back, something which is purely speculative for large theropods.
• Ascended Extra: While the species has barely any screen time in its debut film, an adult is featured as the main antagonist of Jurassic World: Battle at Big Rock.
• Canon Immigrant: Before Fallen Kingdom, Allosaurus's only appearances in the franchise were the video games and toylines.
• Early-Bird Cameo: In Jurassic World, Allosaurus is one of the animals featured in the Innovation Center's Holoscape.
• Funny Background Event:
  • In Fallen Kingdom, one angrily lunges at a Gallimimus for bumping into it during the stampede. In the actual film, however, this gets changed into the Allosaurus attempting to eat the Gallimimus, which doesn't do anything to provoke it.
  • In Dominion, one Allosaurus set loose in the Amber Clave Market is seen enjoying itself a nice human caught on fire from a barbecue.
• Know When to Fold 'Em: The one that shows up in Battle at Big Rock wisely decides to let the baby Nasutoceratops go free after both of its parents show up. It also decides to retreat after receiving two crossbow arrows to the face.
• Out of Focus: Doesn't get to do much in Fallen Kingdom compared to its fellow theropods. While the other carnivores are each given at least one scene where they attack the humans, the Allosaurus is only really remembered for getting taken out by volcanic rock and then being the second dinosaur sold in the auction. It doesn't even get a promotional render, unlike the other new dinosaurs. However, Allosaurus eventually does gain more focus in Battle at Big Rock and Dominion.
• Recurring Extra: The Allosaurus never gets a major scene of its own, but is featured quite noticeably during the stampede scenes. A few can be seen fleeing as Mount Sibo erupts and after Maisie sets all the dinos free. All of these change when Allosaurus receives larger roles in Battle at Big Rock and Dominion.
• Remember the New Guy?: Allosaurus wasn't included on the list of dinosaurs featured in Jurassic World. Granted, it does show up on the Holoscape.
• Shown Their Work: In Battle at Big Rock, the adult Allosaurus is shown to have non-pronated wrists, a first for the franchise. Furthermore, it is based on specimens from the new species A. jimmadseni and manages to be a fairly accurate representation of it.
• Super-Persistent Predator: In a first for the franchise, Averted - during the events of Battle at Big Rock, it initially focuses on attacking the baby Nasutoceratops, but backs off after the baby's father shows up. And while it does try to eat the humans, it runs off after being hit with a piece of metal, hosed down with a fire extinguisher, and taking two crossbow bolts to the face.
• What Happened to the Mouse?: An adult and a juvenile Allosaurus were kept within the Amber Clave Market, the juvenile is first seen battling a juvenile Baryonyx but is not seen again afterward while the Baryonyx is, leaving it ambiguous to whether it was killed in the fight. The adult on the other hand was released into the streets of the Malta, and was last seen rampaging through the city.
• Your Size May Vary: The size of the individual in Battle at Big Rock is notably inconsistent. While it's always far larger than the real animal, it ranges from just slightly bigger than Saurophaganax to appearing even larger than Indominus rex depending on the shot.

Giganotosaurus

Giganotosaurus

Appearances: Jurassic World Dominion

An enormous carcharodontosaurid theropod that appears in a flashback set in the Cretaceous Period, in which it is challenged by a Tyrannosaurus. The genes of this animal were later used in the Indominus rex and the Indoraptor. A cloned specimen is present in Biosyn's compound.

---

• Anachronistic Animal: In the prologue of Dominion, it's portrayed as living 65 million years ago, at the very end of the Late Cretaceous. However, Giganotosaurus is only known from strata 100 to 96 million years old, at the beginning of the Late Cretaceous, more than 30 million years earlier.
• Animals Not to Scale: Zig-Zagged. Side-by-Side comparisons◊ shows it to be larger than the current best-known specimen by at least half a meter and marginally taller than the Tyrannosaurus, who is already an above-average specimen of her species. However, statements by the director and merchandise give a mass of 11 tons and put it as the biggest theropod in the franchise. Even bigger than the ''Indominus rex''. The real Giganotosaurus was roughly the same size as Tyrannosaurus; exactly which of the two averaged as larger is difficult to tell^note The absolute biggest Tyrannosaurus specimens are larger than the largest known Giganotosaurus, but there are far more Tyrannosaurus specimens known and even more of the mature adult T. rex are smaller than the giant carnosaur. When comparing averages, the difference is too close to call. Tyrannosaurus was still taller, but Giganotosaurus was longer. The film size is above the maximum potential range expected for the genus, but not by much. Subverted with the one in the prologue, which is more in scale with the real animal.
• Artistic License – Paleontology: It is covered in crocodilian skin and scutes that form a dorsal sail and a tail fin, none of which the real animal had. Its teeth are also too crocodilian being quite broad and randomly arranged rather than thin, serrated and in neat rows.
• Badass Normal: Being a "pure" clone made entirely for scientific study, it lacks the military-focused genetic engineering augmentations that Indominus and Indoraptor had, such as enhanced intelligence or bulletproof skin. However, its sheer natural size and strength is so great it can manhandle the T.rex handily, just like its precursor did millions of years ago in the past.
• Behemoth Battle: Battles the prehistoric Tyrannosaurus in the Cretaceous flashback after being approached and threatened. Biosyn's Giga fights Rexy twice, the latter fight also involving the Therizinosaurus.
• Big Guy, Little Guy: It has a lowkey symbiosis with the Moros that cleans its teeth. The Giganotosaurus knowingly holds its mouth open to let its compatriot access its teeth so it is a knowing partnership akin to one some birds and crocodiles enjoy. The Biosyn animal seems to retain this trait, as it is seen resting with a Moros calmly walking within a few feet of its jaws.
• Canon Immigrant: Giganotosaurus has appeared in several Jurassic Park games before debuting in Dominion.
• Contrasting Sequel Antagonist: The Giga differs pretty strongly from the preceding post-Lost World big theropods. It is a normal animal with normal motivations, rather than being hyper-intelligent or sociopathic. It also only hunts the humans when they are immediately in front of it and abandons them as soon as it sees the situation wasn't worth it. Upon first encountering the humans, it doesn't charge in an attack on sight but spends time investigating and looking them over like a realistic carnivore confronted an unfamiliar prey for the first time. Its second encounter with them is entirely due to the chip in its brain compelling it to enter the compound, and it is far more interested in tackling its one direct competitor Rexy than chasing some random humans.
• Covered in Scars: Biosyn's Giganotosaurus has numerous scars across its body, with one of the most distinctive being a long strip of missing flesh along its right jaw.
• Dinosaurs Are Dragons: Parodied. During its first encounter with the human characters, Ian manages to distract it by waving around one of the burning locusts on a piece of rebar before thrusting it into the Giganotosaurus's mouth. The dino's resulting roars of pain briefly give the appearance of breathing fire before it can be dislodged. With iguana-like spines and scutes, it also does have a vaguely more dragon-like look than most other theropods.
• The Dreaded: Even the briefest mentioning of the Giganotosaurus is laced with nervousness. Any time it shows up, everyone is terrified, with Alan's describing it as "the biggest carnivore the world has ever seen" containing palpable fear.
• Early-Bird Cameo: An artistic render of a Giganotosaurus is seen on a wall of one of Jurassic World's Main Street stores. Also, its DNA is used in the creation of the Indominus rex and the Indoraptor.
• Enemy Rising Behind: The Giganotosaurus pulls this before bursting through the reinforced glass window right after Owen tells the other main characters that they are safe inside the Biosyn research outpost.
• Final Boss: While not the primary antagonist, it is the final adversary the heroes have to escape from following Dodgson's demise.
• Fluffy the Terrible: The Giganotosaurus was nicknamed by Colin Trevorrow as “Zeb” after the zebra-like stripes on its body.
• Good Lips, Evil Jaws: The crocodile-like maw lacking lips makes it look more monstrous contrasted with the Tyrannosaurus, with its genetic successors like the Indominus rex having the same condition. Somewhat inverted seeing as it was ironically the Tyrannosaurus that was the aggressor in this case, with the Giganotosaurus inoffensively relaxing in the sun when it was challenged. The modern-day animal plays it straighter, portrayed as a terrifying superpredator that has a distinctive elongated scar along its upper jaw.
• Impaled with Extreme Prejudice: Dies when caught between Rexy and the Therizinosaurus; it briefly turns its focus away from the Tyrannosaurus, who capitalizes and puts her full weight behind a throw that shoves the Giga straight onto the claws of the Therizinosaurus.
• Informed Attribute: Marketing for the film, particularly interviews with Colin Trevorrow, played up the Giga as an Axe-Crazy Expy of the Joker, of all characters. It was sold as a chaotic force of nature that just wanted to see the world burn. This turned out to be little more than an attempt to drum up hype, as in the film itself the Giga is no more vicious or insane than preceding big bads. In fact, it may even be less so, seeing as it acts less "psychotic" than the Spinosaurus, Indominus or Indoraptor. The only way it seems more threatening or "evil" than them is that it is in direct opposition to Rexy, the anti-heroic face of the franchise.
• Informed Species: Downplayed, but viewers could be forgiven to mistake it for an Acrocanthosaurus or a buffed-up Concavenator on account of its large, stylized dorsal hump and more crocodilian features such as the Spikes of Villainy adorning its head, as well as lacking the pointed chin and tall skull known from the actual animal (instead having a more pointed, triangular skull and jaw).
• Lightning Bruiser: Capable of moving surprisingly fast and agile enough to keep pace with the smaller and lighter Therizinosaurus and Rexy, whilst being strong enough to shrug off most of the blows either can dish out to it. Having a gout of flame go off in its mouth causes no lasting damage and only gives it a moments' pause. It's also one of the most powerful animals in the franchise, overpowering Rexy twice rather handily and only dying to a lucky hit.
• Misplaced Wildlife: In the prologue of Dominion, it's portrayed coexisting and fighting with Tyrannosaurus rex, despite the fact the two were separated not only by about 30 million years but lived in different hemispheres. T. rex is only known from North America, while Giganotosaurus lived in South America (its name even translating to "giant southern lizard"), and the two continents were separated by the ocean during the Cretaceous.
• Mix-and-Match Critters: Borrows some anatomical traits from fellow carcharodontosaurid Acrocanthosaurus (namely the dorsal hump and thicker tail), likely to make it appear that much more distinctive from the Tyrannosaurus.
• Never Smile at a Crocodile: Though not to the extent of the ''Spinosaurus'', its lipless jaws and extensive osteoderms add something of a crocodilian flavor to its appearance. It's even shown with a smaller dinosaur (the Moros) cleaning its teeth, much like the familiar image of a bird picking food out of a crocodile's teeth.
• Non-Malicious Monster: Despite being promoted as an Ax-Crazy beserker, the Giganotosaurus is this at worst. It's first shown peacefully sleeping, it bullies the Tyrannosaurus away from a carcass after just a brief scuffle, and only attacks the human characters once in the film. Even then, it seems to attack them rather casually, with more curiosity than aggression... until Malcolm scorches its mouth with a burning spear, at which point it understandably gets much angrier.
• Plot-Irrelevant Villain: Is much less involved with the overall plot than previous major predators such as the T. rex pair, the original raptor pack, the Spinosaurus, or the Indominus and Indoraptor. Instead of pursuing the main characters for much of the film, it only attacks them once in the third act, and also shows up in the finale for a final battle with the T. rex (it wasn't even pursuing the heroes; they just happened to show up just as it was about to throw down with Rexy).
• Predators Are Mean: Subverted. It pays no mind to the Moros scavenging off scraps stuck to its teeth and ignoring a nearby Iguanodon. The only reason it winds up fighting and killing the Tyrannosaurus was that the latter approached and was aggressive towards it. Played straighter with the cloned animal, which acts in a typical fashion for a Jurassic carnivore, but more in line with a Tyrannosaurus than the Spinosaurus or hybrids.
• Predecessor Villain: Of sorts. Its species' genes went into the creation of the Indominus rex and the Indoraptor. Fitting the trope, it's larger and more powerful than either.
• Prehistoric Monster: Subverted. It's played up as the biggest and most dangerous predator in the world, with interviews comparing it to The Joker of all things, but it only viciously attacks our protagonists after being driven mad by the fire caused by the locusts. It actually leaves the humans alone after getting tased and shot at one too many times.
• The Rival: Establishes itself as the dominant predator of the Biosyn Valley, which naturally compels it to compete with Rexy once she's captured and transported to Italy. The film places a lot of emphasis on the two eventually coming to blows over who will be the top carnivore.
• Shown Their Work: While not a flawless portrayal (see above), it's still one of the more accurate depictions of the animal in fiction as of late. It has non-pronated hands, an extended dorsum, and a shorter, deeper skull with extensive keratin ridges, which it uses as a battering ram true of carcharodontosaurids. The one in the prologue is also roughly the same size as Tyrannosaurus, as opposed to towering over it. Interviews by Colin Trevorrow reveal the underlying skeleton used to create the design is quite accurate, with the Spikes of Villainy all being soft tissue to play within the realms of the unknown for artistic freedom.
• Single Specimen Species: It is the only known cloned member of it’s kind in the franchise. After it was killed by the T. rex and Therizinosaurus it has presumably fallen back into extinction.
• Spikes of Villainy: Sports a row of iguana-like spines down its back and is played as the threatening antagonist against the familiar Tyrannosaurus. Subverted as it is just a natural creature competing with another apex predator for territory and not a manic monster like the Indominus rex or the Indoraptor.
• Strong Family Resemblance: On a taxonomic family level, its hand and skull shape coupled with sporting display spines down its back closely resemble the Allosaurus. Owen briefly mistakes it for the Allosaurus he was familiar with back in Jurassic World, with Kayla correcting him. It also bears a passing resemblance to the Indominus rex, which had some of its genetic material used in it.
• Use Your Head: It uses its head as a battering ram against an attacking Tyrannosaurus. This is Truth in Television for carcharodontosaurids.

Ceratosauria

Carnotaurus

Carnotaurus

Appearances: Jurassic World: Fallen Kingdom | Jurassic World: Camp Cretaceous | Jurassic World Dominion

An abelisaur known for its large brow horns and nigh-vestigial limbs. They were bred and kept for Jurassic World and survived the events after the park's fall. Several were captured and released into California once the island's volcano erupted.

---

• Adaptational Late Appearance: They appeared in the second novel, but not the second film that loosely adapted it. It wouldn't be until the fifth film that Carnotaurus showed up.
• Adaptational Mundanity: In its appearance in The Lost World (1995), Carnotaurus were depicted with super-advanced camouflaging abilities on par with a Predator's cloaking device, allowing them to become nearly invisible in the blink of an eye. This version lacks that ability, which was never considered likely for any animal to possibly possess, even at the time.
• Adaptational Wimp: In The Lost World (1995), the Carnotaurus were regarded as The Dreaded and were very skilled hunters thanks to their ability to camouflage, to the point even the Tyrannosaurus and Velociraptors would steer clear of their path. Here, not only does it fail to get a single kill, but it's also on the receiving end of one of the biggest Curb Stomp Battles in Jurassic Park history. That, and it doesn't possess the camouflaging abilities of its book counterparts.
• Always a Bigger Fish: On the receiving end of this, at the jaws of the Tyrannosaurus.
• Animals Not to Scale: Slightly bigger and taller than the real-life animal, which is notable when you compare them in scenes next to Rexy, who is large even for a Tyrannosaurus. Played straight with the black scarred Carnotaurus seen at the end of Fallen Kingdom. Compared to the real animal, it's about 3/4 of the size of Rexy and in Dominion is a comparable size to the adult Allosaurus.
• Artistic License – Paleontology: While fairly good by Jurassic World standards, it's a bit oversized and its arms are too long and well-built. The real animal had absurdly stumpy, vestigial arms that didn't even have elbows or palms, and may not even have had claws. It is also depicted with rows of spiky osteoderms on its back when the real animal had no dermal armor. At the time of Fallen Kingdom it was thought to instead have large conical feature scales arranged in rows^note at the time of Dominion it is known that feature scales of Carnotaurus were arranged in a shotgun pattern.
• Butt-Monkey: Quite possibly suffers the most ass-kicking in a single Jurassic Park film. Fails to kill a Sinoceratops, gets attacked by the T. rex, and later doesn't even get to eat the main villain; the kill is abruptly taken by the T. rex, with the Carnotaurus only getting a leg. And then Rexy smacks that out of its mouth and drives it offscreen. And then in the next film, it constantly gets kill-stolen by an Allosaurus. Carnotaurus can't catch a damn break.
• Canon Immigrant: Carnotaurus was featured in the novel version of The Lost World (1995), making this the genus' second appearance in any official Jurassic Park canon. Granted, this version doesn't appear to have the chameleon-like camouflaging ability of the novel counterpart. It also appeared in the "soft canon" book Jurassic Park Adventures - Prey.
• Covered with Scars: One of the Carnotaurus in Lockwood Estate has a heavily scarred face and a broken left horn.
• Curb-Stomp Battle: Gets taken down with minimal effort by Rexy.
• Early-Bird Cameo: Carnotaurus DNA is used in the creation of the Indominus rex and the Indoraptor.
• Fan Nickname: The primarily black animal from Fallen Kingdom and Dominion has a colour scheme that bears a striking resemblance to Kenner's 'Demon Carnotaurus ' action figure from the original Jurassic Park toy line. This has unsurprisingly led many in the fandom to nickname it Demon.
• Neck Snap: The Carnotaurus Rexy takes down is killed from a broken neck when, as she's retreating from the eruption, she steps on its neck. You can see its tail flailing for a moment before going limp.
• Remember the New Guy?: Carnotaurus wasn't included on the list of dinosaurs featured in Jurassic World, although it is listed as one of the DNA contributors for the Indominus rex, so they may have been kept separate. Jurassic World: Camp Cretaceous establishes that they were present at the time of the first Jurassic World, but had been removed from public view at some point.
• Shown Their Work: Unlike Disney's version, this one is sized and proportioned more like the real animal, albeit a bit oversized. As far as Jurassic Park dinos go, it's relatively accurate aside from the wrongly-pointing wrists, clawed hands, and slightly misshapen skull.
• Skewed Priorities: During the island's demise, one of them is more concerned with finding a meal than reaching safety from the volcanic eruption.
• Super-Persistent Predator: Despite the threat of imminent death by the volcano, the Carnotaurus chooses to waste time by fighting a Sinoceratops and then trying to make an easy meal of some humans, something which ultimately nets its defeat by Rexy the Tyrannosaurus.
• Villain Decay: Although the Carnotaurus isn't villainous and is simply a carnivorous animal, it is introduced as a terrifying threat to the main characters in Jurassic World: Fallen Kingdom, but is quickly turned into a Butt-Monkey on the receiving end of several Curb-Stomp Battles with other dinosaurs, especially Rexy.
• What Could Have Been: It was originally scripted to make its film debut in Jurassic Park III but was switched out for Ceratosaurus(see below).
• What Happened to the Mouse?: An adult and a juvenile Carnotaurus were kept within the Amber Clave Market; the juvenile is last mauling Rainn Delacourt, while the adult on the was released into the streets of the Malta and was last seen rampaging through the city.

Ceratosaurus

Ceratosaurus

Appearances: Jurassic Park III | Jurassic World: Camp Cretaceous

A medium-sized carnivore with a horn on its nose and a row of osteoderms running from its head to its tail. The species was originally bred and released illegally on Isla Sorna after the events of The Lost World: Jurassic Park, and were later held in Jurassic World.

---

• Adaptational Species Change: From the screenplay and in junior novelizations for the third film, where it was a Carnotaurus.
• All There in the Manual: According to promotional material for Jurassic World and Jurassic World: Fallen Kingdom, it was illegally created in secret by a splinter group of Masrani Global, then fed and experimented on in captivity for nine months. When the laboratory was abandoned, it was released into the wild.
• Amazing Technicolor Wildlife: Some individuals have a bright red head and a yellow body with black striping.
• Animals Not to Scale: Downplayed. It's slightly bigger than a real Ceratosaurus.
• Animal Reaction Shot: Has a rather hilarious Oh, Crap! look on its face after smelling some Spino poop.
• Anti-Climax: When it appears, we're led to believe it'll attack the human protagonists, but once it smells the Spinosaurus dung on its territory, it simply leaves the scene quietly, and probably didn't even notice Grant and his team.
• Artistic License – Paleontology: Pronated forelimbs aside, this Cerato also lacks the real animal's rather prominent brow horns and has a much more robust skull and body.
• Ascended Extra: Gets a single scene where it does next to nothing in its Jurassic Park III as its introduction, but in Jurassic World: Camp Cretaceous it gets five major scenes, two of which involve them hunting the campers.
• Aside Glance: As mentioned on Animal Reaction Shot above, the look on its face just screams "No way I'm sticking around here" after smelling the Spinosaurus excrement.
• The Bus Came Back: Much like the Spinosaurus, this species had not been seen since Jurassic Park III but shows up 20 years later in Camp Cretaceous.
• Canon Foreigner: Its role was originally destined for Carnotaurus, which first appeared in the novel version of The Lost World: Jurassic Park, but was ultimately replaced by Ceratosaurus. Carnotaurus itself would later make its cinematic debut in the franchise in Jurassic World: Fallen Kingdom.
• Oh, Crap!: The look on its face after smelling Spino poop says it all. Yep, that's right—this dinosaur had an Oh, Crap! moment from a literal pile of crap.
• Pale Females, Dark Males: Implied. Camp Cretaceous features Ceratosaurus with two different colors. One is colored the same as the animal from Isla Sorna, the other is a uniform grey color. These are likely a male and a female, respectively.
• Predators Are Mean: Subverted. When hungry, they're as aggressive as any of the other carnivores, but we also see that in other circumstances they're relatively calm. Kenji and Darius cross paths with one that was on its way to a watering hole who, while curious, paid them no mind and was tolerant of drinking alongside the boys as well as many herbivores.
• Prehistoric Monster: While it does have a rather monstrous design, it is notably enough one of few creatures in the franchise to avert this trope. Even its design is in some ways (size aside) toned down from the real animal, which had an extra pair of smaller horns over its eyes and more prominent osteoderms.
• Screw This, I'm Outta Here: After smelling the Spinosaurus dung nearby the riverbank, it calmly leaves the scene while uttering a long, moaning growl.
• Shown Their Work: Its appearance in the third film having it skulking along a riverbank for something to eat is in line with how paleontologists think the real animal lived and prowled for its food during the late Jurassic.
• What Happened to the Mouse?: It's unknown if any of the Nublar population survived the events of Jurassic World: Fallen Kingdom, although it can be assumed the population on Sorna is fine if the one on Mantah Corp Island is any indication and may have been relocated to the Biosyn sanctuary in Jurassic World Dominion among the other Sorna dinosaurs. ^note It was initially assumed that a list on the Dinosaur Protection Group website listed extinct dinosaurs, but it was later confirmed that the animals listed were simply "treated with cruelty"
  • It’s unclear what happened to the individual on Mantah Corp Island as it was last seen tranquilized by a BRAD-X.
• The Worf Effect: In Season 3 of Jurassic World: Camp Cretaceous, one Ceratosaurus is killed by Scorpios rex to demonstrate the hybrid's ferocity and power. The one in the third film possibly counts as a non-lethal version, since it's shown to be afraid of the Spinosaurus just from smelling it.

Spinosauridae

Spinosaurs in general

• Never Smile at a Crocodile: They have crocodile-like heads and sometimes linger near a water source.
• Savage Spinosaurs: They are far more aggressive than their real-life counterparts.

Baryonyx

Baryonyx

Appearances: Jurassic World: Fallen Kingdom | Jurassic World: Camp Cretaceous | Jurassic World Dominion

A spinosaur known for the enlarged claw on its finger. They were bred for both Jurassic Park and Jurassic World, being kept in the Cretaceous Cruise for the latter park until it collapsed. Many were captured and released into the wilds of California once the island's volcano erupted.

---

• Adaptation Personality Change: The official website listed its aggression index as "medium", yet the one in Jurassic World: Fallen Kingdom is ridiculously vicious, chasing Claire and Franklin in a building and not giving up even after getting lava dripped on its face.
• Alas, Poor Villain: The one that goes after Claire and Franklin ends up getting trapped in a room that is rapidly filling with lava.
• Ambiguous Situation: The trio of Baryonyx that appear in Jurassic World: Camp Cretaceous is shown to form a close bond with one another and hunt together, but the one in Jurassic World: Fallen Kingdom is encountered by itself. It is unknown if the pack is a unique situation or if something happened to this individual's pack.
• Art Evolution: The Baryonyx in the films looks radically different◊ from its appearance in the promotional art◊, which was much more colorful and accurate-looking in comparison. Camp Cretaceous introduced individuals with green and red colorations.
• Artistic License – Paleontology: The skull is broader than it should be, it's missing the crest between the eyes, the arms and neck are too small, and the teeth are wrong. It also has rows of crocodile-like scutes down its back, which are purely speculative. For reference here is what Baryonyx should look like.
• Canon Immigrant: Baryonyx has appeared in several Jurassic Park games and toylines before debuting in Fallen Kingdom.
• Dinosaurs Are Dragons: Invokes a bit of this trope, whether or not intentionally. It's slightly draconic-looking, especially when compared to the real thing, and its introduction has it surrounded by lava.
• The Dog Bites Back: A juvenile Baryonyx has been abused by people in the Amber Clave Market, being chained up and given a prosthetic arm to replace the one lost in a fight. Naturally, when it breaks free, it goes after Rainn Delacourt, one of the poachers working for the Amber Clave Market.
• Early-Bird Cameo:
  • Baryonyx first appeared on the park map of the first film.
  • Billy Brennan mentioned Baryonyx when he attempted to identify the Spinosaurus in Jurassic Park III.^note Baryonyx was originally conceived as the primary antagonist of the third film before Spinosaurus replaced it.
  • In Jurassic World, Baryonyx is one of the animals featured in the Innovation Center's Holoscape.
• Made of Iron: One sticks its head THROUGH MAGMA (more than once) to snap at some humans and is unscathed.
• Mama Bear: In the Jurassic World: Blue VR prequel, a mother Baryonyx defends her nest from both Blue and Rexy, even trying to charge the larger predator. It goes about as well as you'd expect.
• Never Smile at a Crocodile: Not exactly a crocodile, but has a head like one. As well as crocodilian-like dorsal armor.
• Savage Spinosaurs: The smaller cousin of the Spinosaurus, but no less dangerous. Even a juvenile Baryonyx is a force to be reckoned with, as Rainn Delacourt discovers the hard way.
• Super-Persistent Predator: One decides to attack some humans, despite being in a building that's caught on fire. It continues trying to eat them even after it's splashed in the face with molten lava multiple times. Must be a character trait of spinosaurids in general.
• Uniformity Exception: A juvenile Baryonyx kept within the Amber Clave Market is easily identifiable from the rest of its species due to its prosthetic arm and its status as the only juvenile individual seen in the films.
• What Happened to the Mouse?: A juvenile Baryonyx was kept within the Amber Clave Market. This individual is last seen mauling Rainn Delacourt, and the fate of it and the other animals within the market is left open.

Spinosaurus

Spinosaurus

"Obviously a super-predator."

Appearances: Jurassic Park III | Jurassic World: Camp Cretaceous

Billy: That's a Tyrannosaurus.

Grant: I don't think so. It sounds bigger.

A super-predator that InGen secretly cloned on Isla Sorna. One individual, which may or may not have been the same one, was captured by Mantah Corp and moved to their island for their fighting ring.

---

• Abusive Parent: Since it’s DNA was used in the creation of Angel and Rebel, which means in some ways it could be considered a “parent” to the pair alongside the Sinoceratops on Nublar who provided the other half of their DNA. This doesn’t stop it from trying to kill them on sight the minute they stepped into the desert Biome.
• Accidental Hero: In Jurassic World: Camp Cretaceous, it accidentally rams its head into a ravine at just the right moment to grab the Smilodon when it has pounced at the campers.
• Adaptational Badass: With the discovery of the dinosaur being more adapted to being an aquatic predator and more suited to hunting fish, the Jurassic Park Spinosaurus becomes a retroactive example of this, being what Grant describes as a "superpredator", being able to run at a moderate pace, which is something the real animal likely couldn't have done, and being able to fight and kill a T. rex. Though given InGen's practice of DNA and genome modification and their experimentation on hybrid dinosaurs, it's possible that the Spinosaurus was genetically engineered to be more impressive than the real deal.
• Advancing Boss of Doom: It plays this role in two of the licensed JPIII games on the Game Boy Advance, namely The DNA Factor and Island Attack. The first one is unique in that it is able to switch positions if the Player Character stays at the edge for too long, forcing the screen progression to also change directions. The latter acts more akin to an Advancing Wall of Doom as there's no way to actually combat the Spinosaurus other than running away from it as fast as you could.
• Advertised Extra: It's featured in several promotional materials for Season 4 of Camp Cretaceous, but it doesn't appear until the last four episodes, and plays a somewhat important role in only one of them. It returns in the latter half of Season 5 and ends up being the Final Boss of the series.
• All There in the Manual: According to the promotional material for Jurassic World and Jurassic World: Fallen Kingdom, it's indicated that the Spinosaurus was created in secret by a splinter group of InGen and Masrani Global scientists—presumably the one which Dr. Wu and later Hoskins were involved with—as part of illegal hybridization experiments. This further hints that it was the hybrid that Dr. Wu mentioned as having been left on the island. It was brought over to Isla Nublar along with the other Site B dinosaurs, but is indicated to have died at some point due to it not being on the list of surviving dinosaurs.
  • This is retconned, or at least de-confirmed, by Jurassic World: Camp Cretaceous, which established that the Scorpios rex was the first hybrid dinosaur created, that it was born on Isla Nublar, and that Masrani knew about it. The implication is that the Spinosaurus was experimented on in some measure, but not in the same way the hybrids were, which likely explains its hatred of humans. Season 4 would later bring back a Spinosaurus highly implied to be the same individual alongside other animals from Isla Sorna, leaving any of the information even more dubious.
• Always a Bigger Fish: It kills the Tyrannosaurus rex after it starts to pursue the heroes.
  • In "Camp Cretaceous", it grabs and kills the Smilodon just as the latter was pouncing on the cornered campers. And they make a note of its size.
    Sammy: I didn't know they made them that big!
    Darius: You're even bigger than I thought!
• Ambiguous Gender: Its gender is never revealed in the original film. Although Alan does refer to the Spinosaurus as “He” there is room for error as he also referred to the Tyrannosaurus as “He” in Jurassic Park despite being aware all of the dinosaurs were bred female. Averted in Camp Cretaceous, where the Mantah Corp animal (strongly hinted to be the same individual) is explicitly referred to by several characters including Darius as a male.
• Animals Not to Scale: The 44-feet long monster in the third film is actually shorter in length than the real animal! And ironically taller than the real animal, according to 2014 studies. The length part might be justified if this animal is not yet fully grown, as it is currently unknown how long it was on Isla Sorna before the events of Jurassic Park III.
• Artistic License – Paleontology: It lacks the crest between the eyes instead having two prominent brow crests like an Allosaurus. In The DNA Factor, the Spinosaurus can actually use its sail as a thrusting weapon, nevermind the fact that the sail itself is composed of relatively fragile bones and would break upon direct hard contact, let alone being used as a weapon.
• Attack of the 50-Foot Whatever: In Jurassic Park III: The DNA Factor, the Spinosaurus that appears as the Final Boss is FAR larger than the one in the movie, being too big for the screen to even display its full body. The only other dinosaur in the game with this distinction is the Brachiosaurus.
• Ax-Crazy: Its depiction in Jurassic Park III makes it out to be an uber-aggressive monster that doesn't give up in pursuit of its prey and it has a tendency to roar often and cause more destruction than necessary, showing that the Spinosaurus is violently temperamental.
• Back for the Finale: In Jurassic Park III: Island Attack, the Spinosaurus briefly appears at the start of the game, where the player is told how to dash to escape it in a short chase. In the final level where all the bosses are fought again, it returns as the final obstacle after the other bosses are defeated.
• Battle Amongst the Flames:
  • Averted in the third film; when Alan Grant sets the petroleum of the boat ablaze, the Spinosaurus becomes intimidated and retreats from the waters.
  • Played straight in the arcade tie-in game by Konami as the Spinosaurus remains despite the flames being ignited in the background, setting up a climactic backdrop for the game's Final Boss.
• Big Bad: In the third film; it's the biggest carnivore on the island and the most threatening creature the team faces.
  • In Season 5 of Camp Cretaceous, Mantah Corp brings it Back for the Finale as the Final Boss of the series.
• Bookends: More of an example in a video game, namely Island Attack; Spinosaurus is one of the first and'' the last dinosaur encountered by Alan Grant, and both encounters have the spinosaur charging towards Grant, who has to escape the dinosaur. Incidentally, the first chase serves as an introduction to the running mechanic and the second serves to challenge the player's skill in running.
• Breakout Villain: The most memorable thing Jurassic Park III did was to put Spinosaurus on the map. Since then, Spinosaurus either appears or is mentioned in most works of the franchise and is usually depicted as a star or heavily recurring dinosaur in video games.
• The Bus Came Back: After its debut Jurassic Park III, the Spinosaurus—implied to be the same one as the specimen on Isla Sorna—made a return as one of the dinosaurs in possession of Mantah Corp 20 years later in Camp Cretaceous Season 4.
• Contrasting Sequel Antagonist:
  • To the Tyrannosauruses from the previous two films. The Tyrannosauruses were antagonizing the heroes based on territorial reasons and ended up being Accidental Heroes, while the Spinosaurus hunts the main cast out of revenge after being wounded. The Tyrannosauruses in both Jurassic Park and The Lost World are first encountered in the rain, while the first appearance of the Spinosaurus is in the day and its final confrontation is in the rain.
  • Also to the Velociraptors in the first film. Both are unnaturally aggressive dinosaurs who target and stalk the human characters for a long duration as well as being avoided by said humans due to the sheer threat they represent. That said, the raptors were defined by their intelligence and being excellent pack hunters while the Spinosaurus compensates by being a massive predator and being unnaturally powerful for its species.
• The Croc Is Ticking: Paul Kirby's satellite phone is still ringing in its belly... somehow.
• Death Glare: When it finds the group right after Alan and Eric reunite with Amanda, Paul, and Billy, the Spinosaurus is standing right there glaring at them.
• Decomposite Character: Forms this with Rexy from the original film for the adult T. rex in the original Jurassic Park novel, as it takes on that Rex's role of intentionally hunting Grant & co. across an island, a trait that was left out of the film Rexy.
• Disproportionate Retribution: Understandably, it would be miffed from having its hide scuffed by a plane, but going far out of its way to ensure that every human associated with the event ends up dead is surely a bit excessive. Later side material suggests its real reasons are because of unethical experiments it was subjected to by humans.
• The Dreaded: The survivors of Isla Sorna and the campers of Camp Cretaceous are doing everything they can to avoid this giant monster that has the power to kill a Tyrannosaurus rex.
• Early-Bird Cameo: Spinosaurus first appeared in Jurassic Park as a toy in the Gallimimus Gift Shop.
• Final Boss: Being the new big predatory dinosaur, Spinosaurus would obviously be in tie-in video games of Jurassic Park III, filling in the role of the final boss in most of them.
  • It's the last dinosaur fought by the player in The DNA Factor. It serves as an Advancing Boss of Doom who could only be damaged by throwing bombs at its face. Also, it could use its sail as a weapon.
  • In Island Attack, it makes its reappearance at the end of "The Harbour". While it plays out the same way it does in the first level, the chase here is more intense as it makes up for several parts of the level, not to mention there are hazards that have to be jumped as well as debris the spinosaur throws at Grant.
  • The arcade games by Konami have the Spinosaurus appear a couple of times, even as the first boss. It persists until the end where it's the last dinosaur fought.
  • Dino Defender has the player hounded by a Spinosaurus throughout the last level, eventually reaching its way to the visitor center where the player has to bring down a large skeleton display to finally incapacitate the Spinosaurus and beat the game.
  • Spinosaurus is the last dinosaur encountered (and obtained) by the player in Dinosaur Battles Of course, the final boss is the Prime Spinosaurus who is clearly meant to be the toughest dinosaur fought by the player.
• Freudian Excuse: Fallen Kingdom supplementary material reveals that, in addition to possibly being bred as a bioweapon, it was subjected to torturous experiments on the black site where it was born, which would explain its hatred of humans.
• Giant Swimmer: It can hunt the group in the water as well as on land. Nowadays this is considered its main hunting method.
• Historical Badass Upgrade: The real Spinosaurus, despite being huge and powerful, preferred to eat fish over red meat (but would have eaten both, if it got the chance). Here, it's depicted as the ultimate superpredator who eats T. rexes for breakfast. It could have killed a T. rex, but on land, it was just as likely to be killed.
• Historical Villain Upgrade: Jeez, did they make this thing into a monster! Much like the raptors in the previous two films, it comes off less like an animal acting on instinct and more like a bloodthirsty serial killer. Supplemental material for Fallen Kingdom gives it an Freudian Excuse for its specific hostility towards humans.
• Improbable Use of a Weapon: One of the tie-in video games to the third film, The DNA Factor shows Spinosaurus being able to use its sail to thrust its prey upwards. This shouldn't even make sense as the dinosaur's sail is made of fragile bones, were meant for supporting the animal's spine, and would easily break it the makes contact with something via brute force.
• Irony: In Camp Cretaceous, this malicious monster's DNA is combined with a Sinoceratops' DNA to make the cutest, most friendly baby dinosaurs to date in the franchise.
• It's Personal: The Spinosaurus hunts the humans across Isla Sorna in revenge for hurting it when they hit it with their plane after Cooper fired upon it several times. Looking closely, one can see the propeller gashes left on its hip and back. It may also be hunting them as revenge for being subjected to torturous experiments.
• The Juggernaut: In Jurassic Park III: Island Attack, the Spinosaurus acts as an Advancing Wall of Doom as the player is given no way of harming it, so the most that can be done is to run away from it.
• Karma Houdini Warranty: It flees at the end of the final confrontation after getting burned. As revealed on the Dinosaur Protection Group's website, it was eventually moved to Isla Nublar where it went extinct once more. Possibly subverted, if the Spinosaurus in the fourth season of Camp Cretaceous is this same individual.
• Killed Offscreen: According to the Dinosaur Protection Group's website, Spinosaurus is listed as a species that has gone extinct again, meaning that this one is most likely dead and was possibly the skeleton mounted in Jurassic World. However, a Spinosaurus appears in the fourth season of Camp Cretaceous, with Kash implying that it's the same specimen.
• Know When to Fold 'Em: It decides to flee from the fire that Alan Grant created with his flare gun and knows that it does not stand a chance against two T. rexes.
• Lightning Bruiser: The Spinosaurus is huge, powerful, fast, and can take a lot of punishments without slowing down.
• Misplaced Wildlife: The Spinosaurus is intentionally left in a desert by Mantah Corp, even though the Jurassic Park species is more adapted for jungles and the real animal is semiaquatic.
• Never Smile at a Crocodile: It has the aquatic nature and the jaws of a crocodile.
• Non-Malicious Monster: Averted to a degree. This thing will prioritize hunting the main characters and will go out of its way to target humans, but only if said humans had already provoked it. Otherwise it tends to act like most large predators. Supplemental materials for Fallen Kingdom give it a Freudian Excuse for this, explaining that it suffered torturous experiments at the hands of humans to explain this and the third film's cast had incited its rage by firing upon it and accidentally hitting it with an airplane.
• Prehistoric Monster: It doesn't so much act like an instinctual animal as opposed to menacing the humans apparently out of malice. The same humans who shredded part of its hide with an airplane's propellers.
• Red Is Violent: It has a very distinctive shade of red on its snout and sail and it is one of the most aggressive and violent dinosaurs shown in the series.
• Roaring Rampage of Revenge: According to William H. Macy, the Spinosaurus was chasing the humans because it's pissed that Nash struck it with a plane. To be fair to it, if you'd just had a plane smash into you, wouldn't you be a bit angry?
• Savage Spinosaurs: The Trope Maker. This Spinosaurus is nasty, aggressive, murderous, sadistic, and inspired future depictions of spinosaurs as savage beasts.
• Shark Fin of Doom: The sail of the Spinosaurus juts out of the water surface like a shark's fin when it is submerged.
• Shown Their Work: Jurassic Park III cemented Spinosaurus's crocodile-like head in the public mind, finally putting the "sail-backed carnosaur" portrait to rest. Whilst outdated now due to discoveries of the genus' limbs and tail post-dating the film, the portrayal in the third movie was considered quite accurate for the time regarding Spinosaurus.
• Single Specimen Species: It is the only known cloned member of it’s kind in the franchise.
• Stealthy Colossus: This thing is enormous, and just as much a predator as the T. rex, and is just as capable of being sneaky despite its size. It gets the drop on Alan's group when they reunite, and there's no hint that it was coming or right there until the phone inside its belly started ringing.
• Super-Persistent Predator: To the point that this particular Spinosaurus used to be the page image. Previous dinosaur antagonists usually had plot-based reasons for following their human quarry, or only encountered them by coincidence. The Spinosaurus on the other hand hunts and stalks the group throughout the third film, following them for far longer than it reasonably should, although it's implied that it's hunting them as revenge for accidentally injuring it with the plane propellers. It does avert this trope once when it's just taken down the T. rex.
• Uncertain Doom: After being defeated by Big Eatie, it’s last seen being pursued by the Eaties into the jungles of Mantah Corp Island, wether they finished it off or it is now exiled to another part of the island is left uncertain as it is not mentioned again afterwards.
• Villain Team-Up: In the final season of Camp Cretaceous, it teams up with the surviving dino Big Bads of previous seasons (Toro the Carnotaurus and Limbo the Baryonyx) for a final showdown with the campers, due to mind control chips inserted into them by Mantah Corp.
• The Worf Effect: Infamously gives this to the Tyrannosaurus rex, offing it in less than a minute and establishing itself as the new ferocious predator on the block. It gets on the receiving end of this in the Grand Finale of Camp Cretaceous, where it gets defeated and driven away by Big Eatie.
• Would Hurt a Child: Being a hyper-aggressive predator, kids and teens are not off the menu regarding what the Spinosaurus can catch. It chases after Eric and his rescue party in the third film and persistently hunts the Campers during the fourth season of Camp Cretaceous. It also shows no hesitation in trying to kill and eat Angel and Rebel.

Dilophosaurus

Dilophosaurus

"...a beautiful but deadly addition...to Jurassic Park."

Appearances: Jurassic Park | Jurassic World (cameo via hologram) | Jurassic World: Camp Cretaceous | Jurassic World Dominion

"One of the earliest carnivores, we now know Dilophosaurus is actually poisonous, spitting its venom at its prey, causing blindness and paralysis, allowing the carnivore to eat at its leisure."

Dilophosaurus was one of the carnivorous dinosaurs bred as an attraction for Jurassic Park. They would later be kept at Jurassic World, with some individuals moved to Mantah Corp Island after the park fell.

---

• Adaptational Wimp: The Dilophosaurus in the book is big enough to lift Nedry off the ground with its jaws, but the film version is much smaller. The one in the first film is a juvenile since the one in the hologram in Jurassic World was as big as a Velociraptor, though it still pales to sizes featured in the novel and in real life.
• All Animals Are Dogs: Nedry assumes this with the Dilophosaurus he encounters, which leads nowhere good. She's a dangerous animal regardless of how cute she initially appears.
• Animals Not to Scale: Subverted. It's depicted in the first film as dog-sized to prevent it from being confused with Velociraptor by the audience, but in reality, the sizes should have been reversed (if anything, the Dilophosaurus should have been considerably bigger than the film's Velociraptor). However, Nedry later states "I thought you were one of your big brothers", indicating it's a juvenile, and some supplementary franchise media have attempted to explain it this way (other times it was said to be an unintentional effect of DNA splicing, but it's inconsistent). The original novel depicts it accurately sized.
• Artistic License – Biology: It having a venomous bite/the ability to spit venom and an extendable neck frill is supposed to illustrate how little fossils alone can tell us about a dinosaur. But these two examples don't work. Venomous snakes (especially spitting cobras) have syringe-like fangs for spitting venom and injecting it into their prey with maximum efficiency, while Dilophosaurus and other theropods had simpler, blade-like teeth used for tearing through flesh. Likewise, frilled lizards actually have various rod-like hyoid bones to help support their extendable frill, and such features have never been found in association with any theropod, plus a frilled lizard's frill is supposed to be a threat display, which would be entirely redundant for a Dilophosaurus, who was the largest dinosaur and the apex predator of Early Jurassic North America, and it already had a display feature in the form of its distinct double crest.
• Artistic License – Paleontology: A big one for the first film that's other mostly accurate (for its time). It's depicted with the ability to spit deadly venom and with a colorful neck frill, but there has never been evidence of any dinosaur in the fossil record having either. It's also much smaller than the real animal was, but it's sometimes been justified as it being a juvenile.
• Bookends: Its introduction sees it killing Dennis Nedry, who was hired by Biosyn to steal dinosaur embryos . In Dominion, one kills Dodgson, the very man who hired Nedry and the current CEO of Biosyn.
• The Bus Came Back: The species returns in Camp Cretaceous after being absent for 28 years, and shows up in Jurassic World: Dominion, marking its first in-person cinematic appearance since the first film in 1993.
• The Cameo: A holographic version of the species makes a plot-relevant cameo in Jurassic World, being projected by Gray to distract one of the raptors.
• Composite Character: The Dilophosaurus fulfill the role of the Tyrannosaurus chicks that killed Dodgson in The Lost World (1995), down to having exactly three dinosaurs that rip him to pieces.
• Cute, but Cacophonic: It starts out as a seemingly curious, playful creature that makes adorable cooing and hooting noises. When it goes into attack mode, it hisses loudly and sounds like an enraged goose standing in the middle of a field of pissed-off rattlesnakes.
• Danger Takes A Back Seat: When Nedry scrambles to get back into his car, the Dilophosaurus he encounters is waiting for him.
• Early-Installment Weirdness: Dilophosaurus is the only dinosaur species that intentionally differs a lot from the real animal in the films in such a drastic way. The only other animal to get changed so much was the Troodon pack in Jurassic Park: The Game and they never appeared onscreen and might not be canon. Book-to-screen adaptations of the Procompsognathus/Compsognathus and Carnotaurus in the later films didn't give either the fantastic abilities they had in the novels, and none of the other dinosaur species in the films have any special abilities (outside of normal inaccuracies) unless they were explicitly genetically modified to have them.
• Game Face: A Dilophosaurus can look pretty unassuming and cute before it opens its frill, bares its teeth, and starts hissing.
• Historical Badass Upgrade: Played with. The frill and Super Spit are fictitious creations of the films, but the one in the first film is also a lot smaller than the real thing (as she's a juvenile).
• Killer Rabbit: There's no doubt the Dilophosaurus is pretty adorable when she first appears... until she opens her frill.
• Poison Is Corrosive: After the Dilophosaurus in the first film blinds Nedry with her venomous spit, a sizzling noise can be heard as Nedry desperately tries to wipe away the black goo, implying that it's burning away Nedry's eyes. Luckily for him, he seems to have gotten it off by the time he realizes the Dilophosaurus has followed him into the car (as his actual eyes don't seem to show any signs of blindness).
• Snakes Are Sinister: While not being a snake itself, its portrayal plays on the creepy aspects of snakes — it has an expandable hood and venomous spit like a cobra, and its warning sound resembles a rattlesnake's rattle.
• Super Spit: It spits thick, black venom that blinds and eventually paralyzes their victims.
• Toxic Dinosaur: The Trope Codifier. The movies give this creature a deadly poisonous spit.
• What Happened to the Mouse?: In Jurassic World. The species is mentioned in Jimmy Fallon's video and he claims that the Gyrospheres can shield people from their venom. This suggests that the species is still on the island, but they aren't listed as park attractions and never appear in person (the aforementioned cameo notwithstanding). It's unknown what happened to them after the first park's downfall, the new park's construction/abandonment, and after Mount Sibo erupted. The reveal of Dilophosaurus packs in Camp Cretaceous Seasons 4 and 5 as well as in Jurassic World Dominion reveals that the species is not extinct.
• A Wolf in Sheep's Clothing: At first, the Dilophosaurus in the first film appears friendly and harmless. Then she suddenly blinds Nedry with her venom and kills him.

Monolophosaurus

Monolophosaurus

Appearances: Jurassic World: Camp Cretaceous

Single-crested carnivorous dinosaurs that were bred for Jurassic World.

---

• Artistic License – Paleontology: Like most of the theropods in the franchise, the Monolophosaurus are shown to have pronated wrists.
• Canon Immigrant: One of the new dinosaur species not seen in any of the films before Camp Cretaceous. Although it has appeared in some of the franchise's video games and toylines.
• Expy: While a real dinosaur, some of its physical characteristics in the series (and the relative obscurity of the species) indicate its appearance may be a roundabout way to include the "real" version of the more famous Dilophosaurus, which was (deliberately) depicted in the original novel and film with inaccurate features, in the franchise.
• From Nobody to Nightmare: Initially let the campers pass by on Segways without much of a reaction. After noticing they went up to the penthouse, they proceed to invade the building en masse via Air-Vent Passageway and terrorize them.
• I Work Alone: According to Darius, they're normally solitary predators. In the show, though, they attack in packs. It's implied they started living in packs to afford some protection from the Scorpios rex.
• Non-Malicious Monster: Before the Scorpios rex changed dinosaur behaviors, the Monolophosaurus lived alone, hunted small prey and carcasses, and was extremely shy and reserved. However, because of Scorpios rex, the Monolophosaurus was forced to hunt in packs, hunt larger prey, and also changed areas. Now they live in groups of up to 9 animals, are more aggressive, and hunt larger prey. After the death of the Scorpios rex, the Monolophosaurus returned to its original behavior.
• Remember the New Guy?: Monolophosaurus is not mentioned at all on the list of dinosaurs displayed at Jurassic World.
• What Happened to the Mouse?: It is unknown if any survived the events of Jurassic World: Fallen Kingdom.
