5	->''"No! It's... it's a '''Calvinosaurus!''' Named after the renowned archeologist who discovered it, the huge Calvinosaur can eat an ultrasaur in a single bite!"''
6	-->-- '''Calvin''', ''ComicStrip/CalvinAndHobbes''

8	Many works are set in prehistory. However, some works just do a few episodes in prehistory, while mostly in other eras. When this happens, they usually have a prehistoric animal be an ancestor of the characters in the show.
9
10	However, most writers [[SmallTaxonomyPools only know a few types of dinosaur]]. When they don't think they can pass off any of them as the ancestor of their character, they tend to use either "Xsaurus", "Xdactyl", "[[TRexpy X. rex]]", "[[RaptorAttack Xraptor]]", "Xdon" or similar naming schemes to quickly create a new species of dinosaur, filling in the template with any word that seems relevant to the beast in question or just looks cool. "Saber-toothed X", "Woolly X", "Cave X", and [[DireBeast "Dire X"]] are also used in a similar manner, usually by sticking the descriptors in front of any given species of modern mammal to create an ice age-themed version of its species. May also sometimes occur in modern-day set dramas involving mutated animals.
11
12	FunnyAnimal characters are usually neanderthals (or what fiction tends to think neanderthals were like) unless they are antagonists.
13
14	Note that this includes both {{portmanteau}}s or {{mix and match critter}}s of a modern-day animal and a prehistoric animal. May intersect with ArtisticLicensePaleontology. Related to DireBeast and PrehistoricAnimalAnalogue and its subtrope TRexpy.

21	* ''ComicBook/AtomicRobo'':
22	** In one of the Free Comic Book Day issues, Dr. Dinosaur manages to make a cyborg ''Tyrannosaurus'' that he dubs a "Futuresaurus Rex".
23	** In a later FCBD issue, he makes a killer "Omnisaur" -- half ''Triceratops'', half ''Ankylosaurus'', [[TooManyHalves and half]] ''Stegosaurus''.
24	--->'''Robo:''' Aren't those herbivores?\
25	''[{{Beat}}]''\
26	'''Dr. Dinosaur:''' ''[to Omnisaur]'' [-You were supposed to tell me everything!-]
27	** Dr. Dinosaur himself claims to be a dromaeosaur and the sole survivor of an ancient dinosaur civilization, but thanks to his numerous anatomical inaccuracies, Robo is convinced he’s just someone’s [[EscapedFromTheLab escaped genetic experiment]], invoking this in-universe.
28	* ''ComicStrip/DennisTheMenaceUK'': At least one strip features a caveman version of Dennis, accompanied by a sabre-toothed Gnasher.
29	%%* ''ComicBook/DisneyMouseAndDuckComics'': Many of these pop out in Duck and Mouse Comics.
30	* ''ComicBook/GarfieldHis9Lives'': The "Cave Cat" segment shows Garfield as a saber-toothed housecat and Odie as a giant green saber-toothed dogsaurus.
31	* "Valley of the Dildosaurs", a 1975 NSFW comic parodying dinosaur movies (mainly "Valley of the Dinosaurs"), even goes on a lampshading tangent: "Yes, we [[ArtisticLicense know]] that Hornysaurus and Vibratodon never lived at the same time!"
32	[[/folder]]
33
34	[[folder:Comic Strips]]
35	* ''ComicStrip/CalvinAndHobbes'': One strip has Calvin pretending to be a TRexpy called a Calvinosaur that's big enough to eat an "ultrasaur" [[note]]At the time the comic was written, ''Ultrosauros'' was believed to be the largest dinosaur of all time. It was later determined that "Ultrasauros" was actually a chimera made from bones of ''Brachiosaurus'' and ''Supersaurus'' that had been discovered in the same quarry and mistaken for being from a single animal.[[/note]] in one bite. Another story arc had Calvin apparently discovering the bones of an unknown dinosaur and naming it the Calvinosaur (which sort of resembled [[Franchise/SuperMarioBros Birdo]] with a rhino horn), until he was informed by his mother that the "bones" he had discovered was just litter someone had buried.
36	* ''ComicStrip/{{Garfield}}'': The title panel of [[https://garfield.com/comic/1989/04/02 this]] strip has Odie as a Dogasaurus.
37	[[/folder]]
38
39	%%[[folder:Films -- Animated]]
40	%%* ''WesternAnimation/MonstersVsAliens'': Insectosaurus.
41	%%[[/folder]]
42
43	[[folder:Films -- Live-Action]]
44	* ''Film/SixtyFive'': The film is filled almost entirely of these, partly by virtue of the main characters being HumanAliens with no concept of dinosaurs (meaning none are given names). There are creatures resembling scaly raptors, a featherless ''Oviraptor''-like theropod, but with [[ToothyBird numerous sharp teeth]], some sort of small bipedal ankylosaur bearing a distinct but [[AccidentallyCorrectZoology almost certainly coincidental]] resemblance to ''Jakapil'', emaciated quadruped reptiles (identified in the soundtrack as ''Lagosuchus'', despite not being dinosaurs and [[AnachronisticAnimal living nowhere near the Late Cretaceous]]) and a gigantic four-legged predator resembling some sort of primitive archosaur, but even bigger than a ''Tyrannosaurus''. The only identifiable animals are two ''Tyrannosaurus''.
45	* ''Film/TheBeastFromTwentyThousandFathoms'': The ''Rhedosaurus'' is a massive carnivorous dinosaur that moves around on four legs and has no trouble hanging out at the bottom of the ocean.
46	* ''Film/TheGiantBehemoth'': The eponymous behemoth is called a ''Paleosaurus''. It has the quadrupedal stance and long neck of a sauropod, sharp teeth and claws of a theropod, and crocodile-like scaly skin.
47	%%* ''Film/{{Dinocroc}}'':
48	* ''Franchise/{{Godzilla}}'': The films use this trope as a frequent explanation for its {{Kaiju}}, HandWaving their enormous size and apparently supernatural abilities by saying that they simply aren't on the fossil record and thus anything goes.
49	** Godzilla himself is sometimes described as a dinosaur called a "Godzillasaurus" that mutated and grew to massive size due to exposure to radiation in the 1950s, but other times, like in the original film and the Film/MonsterVerse continuity, it's made clear that he was ''always'' that big.
50	** Anguirus somewhat resembles an ''Ankylosaurus'' but far, far larger. His head horns are similar to those of ceratopsians as well.
51	** Rodan is either a colossal and very fictional relative of the ''Pteranodon'' or another atomic mutation depending on the continuity, much like Godzilla. In the ''Film/MonsterVerse'' setting, he's stated to be an ancient superspecies hailing from the ''Permian'' period, meaning he isn't even a pterosaur at all, but something similar and far older predating the entire pterosaur order by millions of years!
52	** Baragon is a quadrupedal dinosaur that can burrow through the ground like a mole and [[DinosaursAreDragons breathe fire]]. Although he's a fraction of Godzilla's size he's still much larger than any real dinosaur. Strangely, he's got a pair of mammalian-like ears, which has led some fans to consider him a synapsid instead.
53	** Gorosaurus is essentially a Kaiju-sized ''Tyrannosaurus'' with no special abilities. [[BadassNormal He can use his prehensile tail and powerful legs to deliver a nasty kangaroo kick, however]]. Some official sources claim he is a descendant of ''Allosaurus''.
54	** Likewise, Titanosaurus is a massive semi-aquatic dinosaur that resembles a ''Spinosaurus,'' with large sails on his back and a long, crocodile-like snout. There is an actual dinosaur called ''Titanosaurus'' that bears no relation. [[labelnote:note]]HilariousInHindsight upon the discovery that the real ''Spinosaurus'' actually was a semiaquatic dinosaur and possessed a tail fin somewhat similar to Titanosaurus.[[/labelnote]]
55	* ''Film/JurassicWorld'' sees the park shift from reviving known dinosaurs to engineering one of their own, called ''Indominus rex''. Claire explains to Owen that they chose the name to [[NamesToRunAwayFromReallyFast sound scary]] and be easy to remember, as complex names weren't popular with the public. In earlier drafts of the script, she was going to be called ''Diabolus rex''. A ''Stegoceratops'' (''Stegosaur''/''Triceratops'' hybrid) was also going to be in the movie, but was scrapped so that the ''I. rex'' would be the only specially engineered beast, though that didn't stop [[MerchandiseDriven toys of it from being made]]. ''Film/JurassicWorldFallenKingdom'' then takes the ''Indominus'' template and applies it to a RaptorAttack, creating the ''Indoraptor''.
56	* ''Film/KingKong2005'': Given that this adaptation of the 1933 classic has taken paleontology and evolution into account, all of the inhabitants of Skull Island with the exception of human natives are fictional animals with appearances based on their real-life prehistoric counterparts. Their names (not spoken in the movie but [[AllThereInTheManual explained in the supplementary books]]) invoke this trope, such as ''[[TRexpy Vastatosaurus rex]]'', ''[[RaptorAttack Venatosaurus]]'' and ''[[TemperCeratops Ferrucutus]]'', though the [[GentleGiantSauropod token sauropod]] is called simply ''Brontosaurus''[[note]]a genus that, at the time of the production of the movie, was thought to be invalid due to being synonymous to ''Apatosaurus''; [[ScienceMarchesOn in 2015, 10 years after the movie's release, it became a valid name again]][[/note]].
57	* ''Film/ASoundOfThunder'': The film has baboonasaurs, flying batasaurs and the claim that lions are somehow descended from allosaurs.
58	* At the beginning of ''Film/YorTheHunterFromTheFuture'', the title character kills an unnamed dinosaur that looks like a [[MixAndMatchCritters mashup]] of all the best bits of ''Triceratops'' and ''Stegosaurus''. What it's doing in the future is anyone's guess.
59	[[/folder]]
60
61	[[folder:Literature]]
62	* ''Literature/AfterManAZoologyOfTheFuture'': Has saber-toothed weasels and monkeyraptors.
63	%%* ''Dodosaurs: Dinosaurs That Didn't Make It'': Similar puns fill up the book.
64	* ''Literature/GeronimoStilton'': Particularly painful puns (especially if you know Greek and/or Latin) pepper the pages of the ''Cavemice'' books. Notable examples include ''Autosaurus'' (which would mean "self reptile"), a type of dinosaur that's used as a car equivalent, and ''Octosaurus'' ("eight lizard"), which isn't even a dinosaur at all, but a [[TentacledTerror giant octopus]].
65	* ''Literature/GravityFallsJournal3'': In the section based on "The Land Before Swine", Dipper describes Soos as discovering an unknown, vaguely spinosaurus-like dinosaur, and naming it "Raddawgceratops".
66	* ''Literature/ManAfterManAnAnthropologyOfTheFuture'' has saber-toothed humans and ground slothmen.
67	* ''Science Made Stupid'', a parody of children's science books, has a ''Puppisaurus'' in a sidebar about mammal-like reptiles (the group did exist, albeit as a group of animals increasingly closely related to true mammals, but it didn't include a ''Puppisaurus'').
68	[[/folder]]
69
70	[[folder:Live-Action TV]]
71	* ''Series/{{Primeval}}'' usually features real prehistoric animals, like ''Spinosaurus'', ''Pteranodon'', or ''Giganotosaurus'', but occasionally mixes in speculative, made-up ones (as well as made-up creatures from the future). A notable dinosaur example is the Tree Creeper, an arboreal theropod resembling a cross between [[RaptorAttack a featherless dromaeosaur]] and a primate, with a knuckle-walking stance and prehensile tail.
72	* ''Franchise/SuperSentai'' and ''Franchise/PowerRangers'':
73	** In ''Series/PowerRangersTimeForce'', the Quantum Ranger had a dinosaur mecha called the Quantasaurus Rex, or Q-Rex for short. The ''Series/MiraiSentaiTimeranger'' version was simply the V-Rex. ''Series/PowerRangersMegaforce'' would later recycle the Q-Rex name for its dino mecha in homage to the original.
74	** ''Series/BakuryuuSentaiAbaranger'' plays on the Japanese word for dinosaur(s), "kyoryu"; calling their dino-like mecha "bakuryu" ("blastosaurs").
75	** ''Series/PowerRangersDinoThunder'' called its main mecha combination the Thundersaurus Megazord. One episode also had the Rangers' class at a paleontology dig, and when Kira tried to get Dr. O's attention she claimed that she found a "morphasaurus" fossil.
76	** ''Series/KishiryuSentaiRyusoulger'' does a similar wordplay as ''Abaranger'', naming their mecha "kishiryu" ("knightosaurs"). It also involves two made-up species, a "Needlesaurus" (a stegosaurid) and a "Tigersaurus" (a reptilian version of a ''Smilodon'', as opposed to the real-life mammal). When ''Series/PowerRangersDinoFury'' adapted the season, it dispensed with the made-up names and just said these mecha were a Stegosaurus and Saber-Toothed Tiger[[note]]Despite the fact that Smilodon isn't closely related to tigers or any living cat species[[/note]].
77	** ''Dino Fury'' also has Solon, a cyborg dinosaur who identifies her species as Solonosaurus.
78	* ''Series/TerraNova'' is pretty weird about this, featuring real-life dinosaurs like ''Brachiosaurus'', ''Ankylosaurus'', and ''Carnotaurus'' (which were separated by thousands of miles and/or millions of years) alongside made-up dinos like ''Acceraptor'' and ''Ovosaurus''.
79	[[/folder]]
80
81	[[folder:Multiple Media]]
82	* ''Franchise/StarWars'' has the mighty Mythosaur, found on the planet Mandalore. It's a giant kaiju with curling tusks more like an elephant's. In the ''Franchise/StarWarsLegends'' continuity, the Mandalorians hunted them to extinction.
83	[[/folder]]
84
85	[[folder:Tabletop Games]]
86	* ''TabletopGame/DungeonsAndDragons'':
87	** The ''Epic Level Handbook'' describes the prismasaurus, a club-tailed hadrosaur-like dinosaur with a row of rainbow scales running down its back and capable of emitting bursts of magical, rainbow-colored light.
88	** ''TabletopGame/{{Eberron}}'' has a number of made-up dinosaurs to go with the regular dinosaurs found in the setting.
89	* ''TabletopGame/MagicTheGathering'' has several dinosaur cards, of which only a few are real species (a couple of Allosaurs and a Dilophosaur). Made-up species mentioned include Brontodon, Altisaur, Aegisaur, Cacophodon, Monstrosaur, Tuskodon, Dromosaur, Tyrannodon, Fungosaur, Gigantosaurus, Gnathosaur, Aerosaur, Imperiosaur, Vantasaur, Magmasaur, Heliopterus, Pangosaur, Polyraptor, Pyroceratops, Regisaur, Ferocidon, Leosaur, Armasaur, and Badgersaur. (These only account for about half the cards though, many of the rest being more descriptive like "Horncrest", "Sailback", and "Hammerskull"; and there are a whole lot of "[Description] Raptor" cards. "[Description] Ceratops" and "[Description] Pteron" are also used.)
90	* In ''TabletopGame/{{Warhammer}}'', one {{Lizard\|Folk}}men subrace is known simply as "Saurus". Among their [[BeastOfBattle Beasts of Battle]] are such creatures as the Stegadon ("roofed tooth"), the Terradon ("earth tooth", for a toothless flying creature) and the Carnosaur ("meat lizard", a generic name for meat-eating dinosaurs). The Bastiladon, a pseudo-ankylosaur, is actually given a fairly appropriate name meaning "fortress tooth". More explicitly made-up creatures include the spike-covered Razardons and the cave-dwelling, eyeless Troglodons.
91	[[/folder]]
92
93	[[folder:Video Games]]
94	* ''VideoGame/DragonQuest'': Various monsters are modeled and/or named after dinosaurs, and [[DinosaursAreDragons they tend to be classified in the Dragon family]]:
95	** ''VideoGame/DragonQuestII'' has two pterosaurs called the Terrordactyl and Tyrannodactyl.
96	** ''VideoGame/DragonQuestIV'' has another pterosaur family; the earliest variant is simply called a Pteranodon but later versions include the Terrornodon and the ice-breathing Chillanodon. Variants of the Komodo lizard monster also include the Eoraptor and Podokesaurus.
97	** ''VideoGame/DragonQuestV'' introduces a line of Triceratops-turtles, named Tortoceratops, Tyrannoceratops, and Terrorceratops. Further variants appear in ''VideoGame/DragonQuestX'' as Trikaceratops and ''Dragon Quest Walk'' as Sunanosaurus.
98	** ''VideoGame/DragonQuestVI'' includes an axe-wielding dragon monster called a Hackasaurus. One can even join your party. It also has {{Palette Swap}}s called the Axesaurus and Tyrantosaurus, and in ''VideoGame/DragonQuestX'' the Halberdsaurus and Paladinsaurus.
99	** ''VideoGame/DragonQuestMonsters'' has a monster called the Stabosaur, though it would be renamed the Swordgon in later games. Its sequel has a cave dino called the Stalagosaur, which gets a variant in ''VideoGame/DragonQuestOfTheStars'' named the Crevassaurus.
100	** ''VideoGame/DragonQuestVII'' has a sea dragon called the Seasaur. ''VideoGame/DragonQuestVIII'' also has a shark-serpent sea beast with a dino name, but it steals the existing name of Megalodon.
101	** One of the {{Optional Boss}}es in ''VideoGame/DragonQuestIX'' is Tyrannosaurus Wrecks.
102	** ''VideoGame/DragonQuestXI'' has some magic-wielding scholar dragons as monsters; with the earliest version you encounter being called a Professaurus.
103	* ''46 Okunen Monogatari: The Shinkaron'' (the obscure Platform/PC98-exclusive precursor to the way better known SNES game ''VideoGame/EVOSearchForEden'') has the player talking to a musical dinosaur called Sugiyaman (named after the game's composer Koichi Sugiyama). There are also some fictional dinosaur species made up by the creators that lead to speculatuve evolutionary paths (like Gorgon, Reptillian Alien, Goblin, a [[Franchise/DragonBall Shenlong]]-esque Asian Dragon, a Franchise/{{Godzilla}} -esque {{Kaiju}} and others) which often end up as a Main/NonStandardGameOver.
104	** The fictional prehistoric species begin with the second chapter (the Age of Amphibians), with the caption "This character was made specifically for this game and doesn’t exist." appearing ingame. In the level's end you can evolve into a primitive tetrapod and from there can select between 2 branches for the remainder for the game- reptile/dinosaur and synapsid/mammal, with both having possible humanoid options. Around the fifth and penultimate chapter mythical creatures appear, with the above being for the reptile branch (you can also evolve into a Wyvern or an Imp and then become a demon if you align yourself with the BigBad in one of the game's bad MultipleEndings). Gnomes, Orcs, Yetis and Elves belong to the mammal branch instead- some bad endings cause you to evolve into Dwarves, Hobbits, Trolls and Fairies which reference Franchise/TolkiensLegendarium; and if you don't evolve into a Homo sapiens but remain a monkey then you turn into a Franchise/KingKong {{Expy}}. Considering the game combines mysticism with science the plot can feel weird, however the legendary creatures make sense when you find out it's made by the same people who made ''Franchise/DragonQuest''- this gets revealed at one point in the game when you come upon a bunch of [[MascotMook mutated slimes]] and could become one yourself if you make a wrong decision. Listed [[https://community.revolutionarygamesstudio.com/t/evo-thread/1839 here]] for curious players are most of the game's possible evolutions available, both real and made-up.
105	* ''VideoGame/FossilFighters'' calls its revived dinosaurs-and-other-beasts "Vivosaurs". There are also undead Vivosaur variants, "[[DemBones Boneysaurs]]" and "Zombiesaurs"; as well as made-up species like "[[AnIcePerson Frigisaurus]]", "[[PlayingWithFire Ignosaurus]]", and "[[GreenThumb Saladasaurus]]". In ''Fossil Fighters Frontier'', you're given a genetically engineered dinosaur as your partner that changes forms throughout the game. It starts as a "Nibblesaurus", then becomes a "Munchasaurus" and a "Chompasaurus". Its final form averts this trope, instead going by the name "Crimson Ravager".
106	* ''VideoGame/InazumaEleven'': Big and his mother Rockstar are an unidentified species of giant ''Theropod'' dinosaurs.
107	* ''Franchise/{{Pokemon}}'': The very first family in the Pokédex is a line of dinosaur/plant hybrids named Bulbasaur, Ivysaur, and Venusaur. Aerodactyl is also a cross between a gargoyle or a wyvern and a pterodactyl. Later games add a sabertoothed dinosaur named Haxorus.
108	* ''VideoGame/PrimalCarnage'': Among all the real dinosaur and pterosaur species, the token dromaeosaur is a fictional genus called the ''Novaraptor'', a genetically engineered creation which is nearly identical to the ''Franchise/JurassicPark'' raptors in appearance and ferocity, thereby sidestepping any issues regarding [[RaptorAttack inaccuracy in its design]]. It comes in both a scaly and a feathered variant, although the difference is purely cosmetic.
109	* ''VideoGame/TeenageMutantNinjaTurtlesTurtlesInTime'' has a reference to this in the prehistoric level, called "Prehistoric Turtlesaurus". No actual turtlesaurus appear, but funny enough, you fight [[EvilCounterpart Slash]] (who kind of looks the part) as a boss in the SNES port.
110	* ''VideoGame/WorldOfWarcraft'' has {{expies}} of famous dinosaurs roaming around various LostWorld zones. These include stegodons, pterrordaxes, direhorns, and the mighty [[TRexpy devilsaurs]].
111	* ''VideoGame/XenobladeChroniclesX'': One of the common indigens that roams the planet Mira are sauropod-like Millesaurs.
112	* ''VideoGame/YookaLaylee'' includes a dinosaur character that's a throwback to the days of 64-bit gaming, named Rextro Sixtyfourus.
113	[[/folder]]
114
115	[[folder:Web Original]]
116	* ''WebVideo/HitlerRants'': One video had Gunsche informs Hitler that an asteroid had wiped out the dinosaurs ([[AnachronismStew don't ask how Hitler could be there 65.5 million years ago]]) but Hitler whines that the asteroid didn't kill the ''[[SitcomArchNemesis Fegel-saurus]]''.
117	* The "[[http://knowyourmeme.com/memes/philosoraptor Philosoraptor]]" meme.
118	* Website/ThisVeryWiki has named our collection of dinosaur tropes the TropesaurusIndex.
119	[[/folder]]
120
121	[[folder:Western Animation]]
122	* The Mukhtar, a LizardFolk genie hunter from ''WesternAnimation/AladdinTheSeries'', has a birdlike dinosaur he uses as a mount, whom he simply calls "Saurus".
123	* ''Franchise/Ben10'' has two saurian forms among the aliens he can turn into; he calls them "Humungousaur" and "Astrodactyl", while the actual species are named the Vauxausaurians and Pturbosaurians respectively.
124	* ''Westernanimation/TheCroods'' is all about this, where aside from a sloth, the film has prehistoric fauna of [[AmazingTechnicolorWildlife colorful]] MixAndMatchCritters; the one with most screentime is a "Macawnivore", a sabre-tooth tiger colored like a macaw (nicknamed [[FluffyTheTerrible Chunky]]).
125	* ''WesternAnimation/DinoSquad'' has many examples. Most of the mutated creatures created by Victor Veloci are mutated mixes of modern day and ancient creatures. Only the Dino Squad are considered by him the ''perfect'' dinosaurs.
126	* ''WesternAnimation/EekTheCat'': The "Terrible Thunderlizards" segment often uses this. Like a porcupinosaurus, for example.
127	* ''WesternAnimation/TheFlintstones'' sometimes makes vague references to creatures like a "chickensaurus". Additionally, Dino is apparently called a "snorkasaurus", while Hoppy is a kangaroo-like creature called a "hoppasaurus".
128	* ''WesternAnimation/TheFutureIsWild'' features a saber-toothed wolverine, a caracararaptor, and a turtlesaurus (specifically named a snowstalker, carakiller, and toraton).
129	* ''WesternAnimation/IceAge'': Scrat is a saber-toothed squirrel. He is somewhat inspired by ''Leptictidium'', an actual small, hopping prehistoric mammal with a long snout, but the similarities end there. Since the release of the movie, another prehistoric mammal, ''Cronopio'', was discovered to be even more similar to Scrat.
130	* ''WesternAnimation/JohnnyTest'': The catsaurus and catdactyl on Bling-Bling's Island.
131	* ''WesternAnimation/LooneyTunes'': "Prehistoric Porky" shows Porky to be descended from a cavepig, while "WesternAnimation/PreHystericalHare" shows Bugs to be descended from a saber-toothed rabbit.
132	* ''Franchise/MyLittlePony'':
133	** ''WesternAnimation/MyLittlePonyAndFriends'': In "[[Recap/MyLittlePonyAndFriendsE36WoeIsMe1 Woe Is Me, Part 1]]", Woebegone is introduced fleeing from the latest victim of his misfortune, an alligatorsaur, depicted as a very large, draconic reptile.
134	** ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': The ColdOpening for "[[Recap/MyLittlePonyFriendshipIsMagicS6E9TheFaultInOurCutieMarks The Fault in Our Cutie Marks]]" has a filly named Petunia Paleo, a paleontologist pony [[note]]incorrectly referred to as an archeologist[[/note]], discover the remains of a "spiny-backed ponysaurus", whose bones resemble a regular horse's with a row of spikes running down its head and neck.
135	* ''WesternAnimation/PhineasAndFerb'': "The Tri-Stone Area" has Perry as a saber-toothed platypus.
136	* [[InvokedTrope Invoked]] in ''WesternAnimation/{{Primal\|2019}}'' with [[TheDreaded the Night Feeder]]. Most of the other prehistoric animals in the show are easily identifiable as real species. The fact that the Night Feeder ''isn't'', instead resembling [[MixAndMatchCritters some bizarre mishmash of different dinosaurs]], just serves to make it even more [[AnimalisticAbomination obviously unnatural and frightening]].
137	* ''[[WesternAnimation/TheSnowQueen1995 The Snow Queen's Revenge]]'' features an ice pterodactyl called an "Iceasaurus''.
138	* ''WesternAnimation/SpongeBobSquarePants'':
139	** "[[Recap/SpongeBobSquarePantsS3E14Ugh Ugh]]" has [=SpongeBob=], Patrick, and Squidward as a cavesponge, caveoctopus, and cavestarfish, with Gary as a giant snailsaurus.
140	** ''WesternAnimation/TheSpongeBobMovieSpongeOutOfWater'' has a ''Squidosaurus'', a cross between Squidward and a ''Tyrannosaurus rex''.
141	* ''WesternAnimation/TomAndJerry'': "Prehisterics" has Tom as a saber-toothed housecat and Jerry as a cavemouse. During the short they encounter a giant saber-toothed rabbit.
142	* ''WesternAnimation/TotalDrama'': The mammal variant in "[[Recap/TotalDramaUpTheCreek Up the Creek]]". Boney Island is home to, among other things, "woolly beavers", giant tusked rodents that Chris describes as survivors from the Pleistocene.
