History ArtisticLicensePaleontology / WesternAnimation

** Another episode had a ''Film/JurassicPark''-styled ''Velociraptor''.

* The ''WesternAnimation/TeenTitansGo'' episode "Open Door Policy" is very much guilty of this. Not only are the ''Tyrannosaurus'' and ''Velociraptor'' copied off from ''Film/JurassicPark'', ''Triceratops'' looks like one of those "Chinasaurs" complete with sharp teeth, ''Brontosaurus'' also has sharp teeth and is clearly based on a painting by Charles R. Knight (dragging tail, hump-back, stubby limbs, box-shaped head, etc.), and the "Pterodactyl" is a toothy ''Pteranodon'' without pycnofibres. Sergey's Krasovskiy's paintings of ''Abrosaurus'', ''Torvosaurus'', and ''Deltadromeus'' were used (if not stolen) to represent ''Brontosaurus'', ''Tyrannosaurus'', and ''Velociraptor'' respectively.

* ''WesternAnimation/MightyMax'', with its paranormal story lines, had to oblige us with a dinosaur themed episode. An EvilutionaryBiologist used a [[EvolutionaryLevels de-evolution]] machine to turn lizards into dinosaurs. Despite lizards and dinosaurs having some similar features, these two groups are not all that closely related, never mind being descended from each other. Interestingly enough, the de-evolving beam was used on sapient chicken ([[InsistentTerminology "Fowl, actually."]]) Virgil. Even though Virgil should have become a theropod dinosaur, he becomes a pterosaur instead. Pterosaurs are not true dinosaurs, nor are they the ancestors of birds. That said, the after-show [[AndKnowingIsHalfTheBattle educational]] segment did correctly teach that birds are descended from dinosaurs.

This gets even weirder when the after-show segment correctly teaches that birds are descended from dinosaurs.

** ''Zuniceratops'' with a nose horn and being the earliest ceratopsian (''its lack of one'' is the only difference a layman could find between it and a chasmosaurine ceratopsid, and if you're discussing a taxon as obscure as ''Zuniceratops'', there's no excuse for you to not know ''Psittacosaurus'' at the very least).

* The ''WesternAnimation/PeppaPig'' episode "Potato City" has this in-universe. When the kids visit the dinosaur exhibit in Potato City, Edmund Elephant points out that the dinosaurs they have living together didn't actually live in the same era. The kids also get the attendant of the dinosaur exhibit to admit that the only reason they have a dinosaur exhibit at ''Potato'' City is because everything's better with dinosaurs.

** The episode also had a bit of AnachronismStew with ''Parasaurolophus'', ''Maiasaura'', and ''Pteranodon'' existing 67 million years ago, when these are three reptiles that disappeared about 5 million years before then, and ''Pteranodon'' was portrayed as living inland. ''Edmontosaurus'' (or ''Anatosaurus''/“''Anatotitan''”, depending on who you ask) would have been a better substitute for ''Maiasaura'' and ''Parasaurolophus''[[note]]unless undocumented reports of ''Parasaurolophus'' remains in Hell Creek turn out to be true, although lambeosaurines otherwise seem to have disappeared from North America before the end of the Cretaceous. Even then, ''Hypacrosaurus'' would be less an anachronistic choice if the writers needed a crested hadrosaur, since it’s known to have lived only 68 million years ago.[[/note]], and ''Quetzalcoatlus'' would be a more accurate fill-in for ''Pteranodon''. At least this episode decided to stick with late Cretaceous dinosaurs. Similarly, the Cretaceous Alberta scene in the game is mostly based on the Two Medicine Formation but features ''Triceratops'' and ''Ornithomimus'' from the slightly younger Hell Creek Formation.

* ''WesternAnimation/MiraculousLadybug'' runs into a brief instance of this in one episode where a ''Tyrannosaurus'' is shown licking Bunnyx's face in a photograph. Theropod dinosaurs such as ''Tyrannosaurus'' are nowadays believed to have flat tongues similar to those of crocodiles, and would actually be incapable of extending them outside the mouth.

** Also in the song, a sauropod is shown chomping on a ''T-Rex'', while another is correctly shown eating leaves of a tall tree.

* ''WesternAnimation/TheMagicSchoolBus'' episode "The Busasaurus" at least ''tried'' to avert this trope based on [[ScienceMarchesOn the paleontological knowledge when it was made]]. The Frizz took the class [[TimeTravel back in time]] 67 million years (Late Cretaceous Period) specifically to correct Carlos (and the audience) on several pop-cultural misconceptions, the biggest of which was that all dinosaurs were predators. Of about a dozen different species they encounter in the episode, exactly ''three'' were carnivorous. The LicensedGame loosely based on the episode, ''The Magic School Bus Explores in the Age of the Dinosaurs'', was similarly studious. However, [[ScienceMarchesOn Science Marched On]]:
** ''Troodon'' and ''Ornithomimus'' were more likely omnivores rather than straight carnivores as depicted. The latter is particularly egregious, as suggestions that ornithomimids habitually ate plants are OlderThanTelevision.
** And, again, featherless coelurosaurs (it's debatable whether tyrannosaurids were feathered, but there's ''no'' question that troodontids and ornithomimids had them).
** The episode also had a bit of AnachronismStew with ''Parasaurolophus'', ''Maiasaura'', and ''Pteranodon'' existing 67 million years ago, when these are three reptiles that disappeared about 5 million years before then, and ''Pteranodon'' was portrayed as living inland.

At least this episode decided to stick with late Cretaceous dinosaurs. Similarly, the Cretaceous Alberta scene in the game is mostly based on the Two Medicine Formation but features ''Triceratops'' and ''Ornithomimus'' from the slightly younger Hell Creek Formation.
** The ''Alamosaurus'' has flat mammal-like molars instead of the more accurate peg-shaped teeth, and they look more like generic diplodocids.
** The call of ''Parasaurolophus'' was portrayed sounding like a high-pitched dolphin cry. Recent research via digital technology suggests [[https://www.youtube.com/watch?v=d-tRFuMdQkA this wasn't the case]].
** Basal synapsids were identified as reptiles in the LicensedGame.
** The mini-game "Dino Madness" has birds as non-dinosaurs but still described as dinosaur descendants. Strangely enough, Wanda addresses the idea that birds are dinosaurs in the classroom area of the game. Plus ''Archaeopteryx'' is [[ShownTheirWork identified as a dinosaur]].
** In what may also count as another ScienceMarchesOn example, the game uses the name "''Rioarribasaurus''", a suggested alternate name for ''Coelophysis'' that has been officially suppressed.
** In the game, the bus turns into a “rhamphorhynchoid” (long-tailed) pterosaur to travel to the Cretaceous, but these pterosaurs mostly died out in the Jurassic (anurognathids, the only Cretaceous “rhamphorhynchoids”, actually had short tails and look nothing like the game’s pterosaur).
** The game does make a few errors, however, such as claiming plesiosaurs and ichthyosaurs being the only types of marine reptiles (which gets particularly jarring when the game uses an animated StockFootage from ''Series/TheDinosaurs'' featuring a mosasaur and has it referred to as a ''Kronosaurus'') and featuring what appears to be a legless snake in the Jurassic period (although it could be a caecilian).
* ''WesternAnimation/{{Dinosaucers}}'' used ''Apatosaurus/Brontosaurus'' confusion as a RunningGag. When told that "''Brontosaurus''" was an incorrect designation and that ''Apatosaurus'' was the correct one, Bronto Thunder would immediately reply "That's a girl's name!" (he had a girlfriend back on his home planet named Apattysaurus). Dimetro is kind of an oddball here. Sphenacodontids like ''Dimetrodon'' are most definitely not dinosaurs. They are pelycosaurs, the ancestors of the therapsids, who were in turn the ancestors of mammals (in short, Dimetro is a closer relative of the Secret Scouts than he is to any of the Dinosaucers). However, given Dimetro's appearance, it's very possible that the producers had ''Dimetrodon'' confused with ''Spinosaurus''. Old illustrations of ''Spinosaurus'' show an animal that could easily be confused for a bipedal ''Dimetrodon'' (the only good specimen of ''Spinosaurus'' was destroyed during UsefulNotes/WorldWarII -- really). Indeed, Dimetro's head resembles the head ''Spinosaurus'' was drawn with in the 1980s, long before ''Spinosaurus''' relative ''Baryonyx'' was discovered and turned out to have a head that does not look like that of any other large theropod at all. Take a look at [[http://www.flickr.com/photos/babbletrish/5561152515/in/photostream/ this old illustration]] from the time (there's even a direct comparison to ''Dimetrodon'') for an example. Oddly, the show's broad definition of "dinosaur" would actually prove a boon decades later, as one of their number was an ''Archaeopteryx'', which is now classified as a dinosaur.
* ''WesternAnimation/DinoSquad'':
** For his first experiment, Victor Veloci uses his deevolution chemical, which reverts ordinary animals into dinosaurs, to "[[EvolutionaryLevels revert]]" a shark into a "Mutated Megalodon"--except that it's actually a mosasaur, an ocean-going lizard that sharks did not evolve from, and neither of these animals are dinosaurs anyway.
** The show also stated that ''Spinosaurus''' super power was SuperSpeed. Given 2014 discoveries of ''Spinosaurus'', its legs had high bone density, which was useful for buoyancy, but not much for speed.
** The ''Styracosaurus'' in the show is depicted as having having two brow horns that are larger and longer than the nasal horn, when in reality, it should be reversed. The official website accurately states that the brow horns should be smaller--though the site made its own mistakes, such as stating that ''Tyrannosaurus'' dragged its tail along the ground like a kangaroo (which the show itself got right).
** In one episode, Veloci attempts to infect the clouds with primordial ooze so it woud rain down on everything and revert them into dinosaurs--even plants, which are in a different kingdom entirely.
* ''Franchise/{{Transformers}}: WesternAnimation/BeastWars'':
** Generally, the show's okay in terms of accuracy. Megatron, Terrorsaur, and Dinobot turn into a ''Tyrannosaurus rex'', a pterosaur, and some kind of dromaeosaur (likely ''Velociraptor'' or ''Utahraptor'') respectively, but they get their alt modes by scanning fossils rather than living creatures. Then again, all three were found around an area filled with lava and volcanic rock, which would normally destroy fossils.
** Magmatron from the Japanese ''Beast Wars'' series is a multi-component transformer who consists of a ''Giganotosaurus'', a ''Quetzalcoatlus'', and an ''Elasmosaurus.'' The ''Beast Wars Sourcebook'', which adapts the characters for American continuity, apparently didn't get the memo, as they say the three have "only loose connections to actual reptilian lifeforms." To be fair to the sourcebook, the models really do only resemble the aforementioned animals loosely: the ''Giga'' model is a generic-as-it-gets theropod, the ''Plesio'' has an incredibly bendy neck (though this can be forgiven, as it's needed for the transformation) and a lizardlike head with incorrect eye-placement, whereas the ''Quetz'' looks like a scaly vulture with a huge, serrated beak.
** Speaking of Magmatron, the series contains an assortment of dinosaurs as alternate modes for the various villain characters. Most of them were excellent in terms of accuracy, at least for their time... save for [[http://tfwiki.net/w2/images2/1/17/BWNtoy-Hardhead.jpg Hardhead]], who was a remold of Beast Wars Dinobot and was a ''Pachycephalosaurus'' with a ''jaw full of razor sharp teeth'' and the toe talons of a ''Velociraptor.'' Pachys were ''herbivores'', or omnivores at best.
*** The original raptor mold wasn't without its problems either. Besides looking like a JP raptor, it had ''six'' digits on its back feet, creating Dinobot's trademark double-thumbs. It should only have had four. When an upgraded version of the figure was released for the ''Classics/Universe'' toyline, it looked a lot closer to the character's cartoon depiction. But it still suffered from inaccuracies: it had a bent tail, pronated hands and scaly skin (in ''2008''!), in a line that was meant to recreate old characters in updated alternate modes. But at least the new toy did away with the original's spinning shield gimmick, a feature that required the figure to have an elongated button sticking out of its cloaca that you had to push in repeatedly. ''Yuck.''
** [[Franchise/TransformersGeneration1 Transformers G1]] had the Dinobots as how the dinosaurs were popularly thought of at the time: Grimlock was tripod-stanced, Sludge had a swan neck and dragged his tail, Snarl was extremely hunchbacked. Fortunately the Dinobots were much more realistically done in WesternAnimation/TransformersAnimated, Grimlock especially.
** G1 also had the two-parter titled ''Dinobot Island'', where they met horrible depictions of living prehistoric animals. Tail-dragging, Franchise/{{Godzilla}}-sized Theropods, a pterosaur (looking a lot like the relatively small ''Dimorphodon'') lifting Spike up to her nest (filled with eggs ''bigger then the mother''), a bendy-necked plesiosaur (also being able to pick up Spike). And it was written by Donald F. Glut, renowned paleo-expert! Though considering [[CreatorBacklash he hated working on the cartoon]], it is not unreasonable to assume that he ''did'' make himself cry while writing it.
* The ''[[WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius Jimmy Neutron]]'' series was guilty of this in several episodes.

* The ''WesternAnimation/{{Stanley}}'' DirectToVideo movie ''Stanley's Dinosaur Round-Up'': After jumping into the GreatBigBookOfEverything, Stanley encounters a herd of ''Brachiosaurus'', which soon run off, scared by a three-fingered kangaroo-stance ''Tyrannosaurus rex'' that appears to be bigger than the brachiosaurids. Brachiosaurids did ''not'' travel in large herds (they would have stripped large areas of their foliage too quickly), [[AnachronismStew they went extinct about 70 million years before tyrannosaurids evolved]],[[note]] Primitive tyrannosauroids did live along ''Brachiosaurus'', but they were essentially harmless to anything larger than a lamb.[[/note]] they couldn't run ''nearly'' as fast as they did in the show, tyrannosaurs held their bodies horizontal to the ground, had ''two'' fingers per hand and were considerably smaller than ''Brachiosaurus''.
* ''WesternAnimation/DinosaurTrain'' on Creator/PBSKids tends to avert this by having Dr. Scott the paleontologist (portrayed by actual paleontologist Scott Sampson) come in and explain what scientists believe (and an un-named, party-pooper character step in and complain about one of the most fantastical moments in the episode like "Point of fact. Dinosaurs did NOT give music concerts."). That's not to say, however, that it's completely immune to some very odd mistakes (scaly, bipedal and ectothermic pterosaurs, hadrosaurs that only walk on two legs, maniraptorans that either aren't feathered enough or completely featherless and so on).

* ''WesternAnimation/PhineasAndFerb'' tend to run headlong into this trope whenever their daily shenanigans bring them in contact with dinosaurs.
** The episode where the boys ([[MyFriendsAndZoidberg and Candace]]) travel back in time, they encounter sauropods wading in swamps (an idea that has been disproven since the fifties) and has a ''Tyrannosaurus rex'' with ''[[ArtisticLicenseBiology three fingers]]''. They say they went back over three hundred million years. [[http://en.wikipedia.org/wiki/Carboniferous Three hundred million years, huh?]]
--> '''Phineas''': Hey ''[[UsefulNotes/TyrannosaurusRex T. rex]]'', aren't you a little young to be hanging around in the Carboniferous?
--> '''Tyrannosaurus rex''': Why, yes, [[RunningGag yes I am]].
** This trope is played straight again in the episode "Lizard Whisperer", where the boys' American chameleon ([[SomewhereAHerpetologistIsCrying which is a whole other trope in and of itself]]) is enlarged to gigantic sizes, and the boys call it a dinosaur. This one, however, is {{lampshade|Hanging}}d.
** [[RuleOfThree A third instance of this trope]] occurs when Perry the Platypus fights Doofenshmirtz in Hawaii over the [[EvolutionaryLevels "Devolvinator"]]. When the Devolvinator's beam hits Perry and Doofenshmirtz, Perry [[EvolutionaryLevels devolves]] into, among other things, an ''Ichthyornis'' and a ''Triceratops''. [[BigWhat What?]] Platypodes aren't even remotely close to either of these extinct organisms. Don't the creators even listen to their own song, he's a semi-aquatic ''mammal'' of action. Though given how Doofenshmirtz's evolutionary stages weren't exactly accurate either and got a ''giant ear'' in one of them ("[[LampshadeHanging Okay, this I don't even get]]."), it might have been PlayedForLaughs. Also probably justified as "Brain Drain" suggests that Doofenshmirtz himself doesn't know even what evolution actually is, only that it is "something to do with monkeys".
** Averted in "Boyfriend from 27,000 BC", which showed frozen prehistoric animals representing the time periods and epochs they're from (''Stegosaurus'' for Jurassic, ''Pteranodon'' for Cretaceous, a mammoth for Pleistocene, and a neanderthal for Paleolithic).

* ''WesternAnimation/MightyMax'', with its paranormal story lines, had to oblige us with a dinosaur themed episode. An EvilutionaryBiologist used a [[EvolutionaryLevels de-evolution]] machine to turn lizards into dinosaurs. Despite lizards and dinosaurs having some similar features, these two groups are not all that closely related, never mind being descended from each other. Interestingly enough, the de-evolving beam was used on sapient chicken ([[InsistentTerminology "Fowl, actually."]]) Virgil. Even though Virgil should have become a theropod dinosaur, he becomes a pterosaur instead. Pterosaurs are not true dinosaurs, nor are they the ancestors of birds. This gets even weirder when the after-show segment correctly teaches that birds are descended from dinosaurs.
* ''WesternAnimation/TheNewAdventuresOfSuperman'' episode "Prehistoric Pterodactyls". Did you know that pterodactyls (actually depicted as impossibly large Pteranodons) can catch fighter jets in their mouths, [[ImmuneToBullets survive direct hits from missiles and naval gunfire]], go one-on-one with Superman and survive in space? According to this episode they can!
* According to the ''WesternAnimation/JonnyQuest'' TOS episode "Turu The Terrible", pteranodons are much larger than human beings, can fly while carry a human being in their talons, and can survive multiple direct hits by bazooka rounds.
* In the ''WesternAnimation/JohnnyTest'' episode "Johnny BC", the sister's teacher makes them look for a fossil from precambrian times, so the sisters go back to caveman times for a 3-toed sloth fossil to plant where they were looking. Too bad precambrian times ended 540 million years before cavemen appeared.
* In ''WesternAnimation/JorelsBrother'', dinosaurs are an alien species that lives in another planet; they are able to speak and live mostly like humans, except they have an extremely short attention span. In another episode, it's revealed that the series' entire world is located in the lice of alien dinosaurs. This trope is also parodied in "Shostners Games"; at one point, a song's lyrics mention that humans coexisting with dinosaurs is historically inaccurate... because dinosaurs were never real.
* The ''WesternAnimation/BatmanBeyond'' two-parter "Curse of the Kobra" involves the KOBRA organisation's attempts to gene-splice themselves into a dinosaur-human hybrid race that will rule the world. Their plans include detonating a nuclear warhead in a dormant volcano, with the resulting eruptions raising the global temperature. Why? [[SarcasmMode Because everyone knows dinosaurs are cold-blooded, and can't survive let alone function in less than tropical climates]]. The spliced ''BigBad'' even weakens and collapses as soon as his climate-controlled environment is breached, acting as though he's going to die immediately because his plan was foiled.

* The eponymous ''WesternAnimation/DenverTheLastDinosaur'' doesn't seem to belong to any known species. Apparently he's supposed to be a ''Corythosaurus'', explaining the mohawk-like head crest...but he doesn't look much like a hadrosaur either.
** Made even worse by the reboot series ''WesternAnimation/DenverAndCliff'', where not only does Denver look ''nothing'' like his 80s counterpart save for being green, he also has a very long prehensile tongue and can change his color to camouflage, being a mix between a chameleon and Yoshi.
* The Nick Jr show ''WesternAnimation/BubbleGuppies'' did an episode on dinosaurs....thing is they included Pterosaurus and Marine Reptiles as dinosaurs. This is supposed to be educational. To be fair, they did go out of their way to use ''Apatosaurus'' instead of "Brontosaurus".
* The AnimatedAdaptation of the Belgian action-adventure comic series ''WesternAnimation/BobMorane'' had an episode dealing with TimeTravel. Naturally, all of the creatures the characters meet are ''Jurassic Park''-inspired, down to the frilled ''Dilophosaurus'', which is also [[AnachronismStew misplaced in time to the Late Cretaceous]] (actually lived in the Early Jurassic, almost 150 million years earlier), but at least they got its size right. The episode also has stampeding "raptors", and mountain-sized dino skeletons that the heroes use as bridges to cross a [[QuicksandSucks quicksand swamp]].

* According to one episode of ''WesternAnimation/IAmWeasel'', the earth was flat during the Mesozoic and that dinosaurs died because they laughed at I. R. Baboon's red butt and fell off the flat earth. And then there's the caveman-themed episode, with dinosaurs included. Given the show's setting, none of these are unusual.
* ''WesternAnimation/TheFlintstones'': Dinosaurs are shown coexisting with humans: mammals that existed up through the Cretaceous were small and rodent-like. That [[MST3KMantra hardly matters]].
* ''WesternAnimation/{{Arthur}}''
** The title card for the episode "Sue Ellen & The Brainasaurus" misspells "-saurus" as "-saurous".
** The episode "In My Africa" mentions dinosaur bones found in Angola. . . accompanied by a photograph of a mosasaur skull.
* In the ''WesternAnimation/{{Rugrats}}'' episode "Reptar 2010", the main characters watch a Reptar movie that claims dinosaurs ruled the earth ''fifty thousand years ago''. Possibly justified since Reptar is a Franchise/{{Godzilla}} expy, a franchise that isn't exactly known for scientific accuracy in the first place. A better example is an episode where the protagonists visit a museum and learn that ''T. rex'' [[AnachronismStew is from the Jurassic]]. They're at least 80 million years off.
** In one chapter book from 2002, "In Search For Reptar", Lou claims dinosaurs didn't have feathers. Although this could be chalked up by him not being up-to-date with modern theories.
* Having been made in 1979, the pilot episode of the French {{Edutainment}} cartoon ''WesternAnimation/IlEtaitUneFois l'Homme'' (''Once Upon a Time... Man'') gets a free pass in most respects, but it's still odd how the animation shows birds descending from non-dinosaurian thecodonts and yet the narrator insists later on that they've (along with crocodiles) also evolved from dinosaurs.
* The caveman episode of ''WesternAnimation/GoofTroop''. Perhaps the biggest offender is that what looks like an outdated representation of a carnivorous theropod was referred to as a ''Brontosaurus''. Interestingly, while the creature in question was shown eating meat, Goofy points out that ''Brontosaurus'' were herbivores. Then again, it was [[BookDumb Pete]] who called the creature a ''Brontosaurus''.
* The "Scary Monsters" episode of ''WesternAnimation/TimothyGoesToSchool'' perpetrates old, debunked claims like carnosaurian-looking ''Velociraptor'' and pterosaurs that hang upside-down like bats (although some things, like sauropod nostrils being on top of the skull, are actually ScienceMarchesOn). ''Megazostrodon'' is called a dinosaur (it was a primitive mammaliaform), and the model shown looks nothing like the real animal.
* ''WesternAnimation/TheFairlyOddparents'' often depicts ''Tyrannosaurus rex'' with a ''kangaroo-stance''. Strangely, they got it right in the opening of ''Abra-Catastrophe'' with Wanda's ''T. rex'' form. There's scaly, bat-winged pterosaurs and sauropods with crocodilian belly-scales, and one episode "Movie Magic" had a ''Triceratops'' with a ''spiked tail''. A more recent episode had dinosaurs living with cavemen in 50,000 BC. Given the nature of the show, however, these inaccuracies hardly seem out of place.
* Lampshaded in an episode of ''WesternAnimation/EdEddNEddy'' which involved one of the Eds' scams as taking the kids back in time to the Triassic period, and they use ''Triceratops'' and ''Tyrannosaurus'' as the fake dinosaurs to terrorize the kids. [[TheSmartGuy Double D]] found this amusing, since these dinosaurs were actually from the Cretaceous.
* This occurs in Creator/DingoPictures' "WesternAnimation/DinosaurAdventure" because of laziness and a desire to reuse animation from one of the studio's previous movies. The main character and his parents are clearly members of different species, herbivores can become carnivores, and animals from the Age of Mammals coexist with dinosaurs.
* The ''WesternAnimation/PeppaPig'' episode "Potato City" has this in-universe. When the kids visit the dinosaur exhibit in Potato City, Edmund Elephant points out that the dinosaurs they have living together didn't actually live in the same era. The kids also get the attendant of the dinosaur exhibit to admit that the only reason they have a dinosaur exhibit at ''Potato'' City is because everything's better with dinosaurs.
* The ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "The Fault in Our Cutie Marks" features a filly with a skull cutie mark, whose parents are initially disturbed until she discovers a dinosaur in her backyard, whereupon they cry in unison, "She's an archaeologist!" Uh, no she's not; she's a palaeontologist. Made especially jarring considering the filly's name is Petunia ''Paleo''.
* The ''WesternAnimation/TeenTitansGo'' episode "Open Door Policy" is very much guilty of this. Not only are the ''Tyrannosaurus'' and ''Velociraptor'' copied off from ''Film/JurassicPark'', ''Triceratops'' looks like one of those "Chinasaurs" complete with sharp teeth, ''Brontosaurus'' also has sharp teeth and is clearly based on a painting by Charles R. Knight (dragging tail, hump-back, stubby limbs, box-shaped head, etc.), and the "Pterodactyl" is a toothy ''Pteranodon'' without pycnofibres. Sergey's Krasovskiy's paintings of ''Abrosaurus'', ''Torvosaurus'', and ''Deltadromeus'' were used (if not stolen) to represent ''Brontosaurus'', ''Tyrannosaurus'', and ''Velociraptor'' respectively.
* ''WesternAnimation/TheSimpsons'': The HollywoodPrehistory setting Homer encounters in "Time and Punishment", the second segment from ''Recap/TheSimpsonsS6E6TreehouseOfHorrorV'', features (in addition to the expected dinosaurs and pterosaurs) pelycosaurs, a ground sloth and what is presumably intended to be a primitive sarcopterygian (lobe-finned fish). Obviously [[AnachronismStew none of these animals lived at the same time]], but [[WillingSuspensionOfDisbelief the Treehouse of Horror episodes aren’t meant to be taken seriously anyway]].
* ''WesternAnimation/FredTheCaveman'' had dinosaurs wandering around a prehistoric world... in which cave-people existed.
* ''WesternAnimation/Primal2019'' takes place in a HollywoodPrehistory setting with [[AllCavemenWereNeanderthals Neanderthal-like cavemen]], inaccurately portrayed dinosaurs (including horned ''Tyrannosaurus rex'', [[TerrorDactyl monstrous pterosaurs]] and [[RaptorAttack large, scaly raptors]]), ice age mammals, [[FrazettaMan savage ape-men]] and downright impossible fantasy creatures like [[BatOutOfHell monster bats]] and a GiantSpider. It's a fantasy story taking place in a primordial world, and any similarity to real prehistory is pure coincidence.
* ''WesternAnimation/XiaolinShowdown'': "Oil in the Family" features a three-fingered, tripodal ''Tyrannosaurus rex''. The same episode reinforces the idea that oil is made from decomposed dinoasaur remains.
* Interdimensional spy Tomoko (Kimiko's sister) from the ''WesternAnimation/XiaolinChronicles'' episode "Tigress Woo" has a size-shifting pterosaur (its species is not identified, but it has a ''Pteranodon'' crest) named Dina which she uses as a mean of transport. As always, it's scaly, bipedal, with bat wings and its name obviously shouts "dinosaur". Justified, for being a magical creature from another dimension.

* ''WesternAnimation/SuperDinosaur'', an AnimatedAdaptation of [[ComicBook/SuperDinosaur the Comic Book of the same name]], renamed the character Terrordactyl (Pterodactyl) into Terroropterx (Archaeopteryx). By the way, the name is the only thing it changed with the character, he wasn't [[AdaptationSpeciesChange changed from a pterodactyl to an archaeopteryx]] to fit the new name.

* ''WesternAnimation/{{Bobobobs}}'' has humans and dinosaurs coexisting during the same time period on Earth.

** The episode also had a bit of AnachronismStew with ''Parasaurolophus'', ''Maiasaura'', and ''Pteranodon'' existing 67 million years ago, when these are three reptiles that disappeared about 5 million years before then, and ''Pteranodon'' was portrayed as living inland. ''Edmontosaurus'' (or ''Anatosaurus''/“''Anatotitan''”, depending on who you ask) would have been a better substitute for ''Maiasaura'' and ''Parasaurolophus''[[note]]unless undocumented reports of ''Parasaurolophus'' remains in Hell Creek turn out to be true, and then ''Hypacrosaurus'' would probably be a more period-appropriate choice if they wanted a crested duckbill.[[/note]], and ''Quetzalcoatlus'' would be a more accurate fill-in for ''Pteranodon''. At least this episode decided to stick with late Cretaceous dinosaurs. Similarly, the Cretaceous Alberta scene in the game is mostly based on the Two Medicine Formation but features ''Triceratops'' and ''Ornithomimus'' from the slightly younger Hell Creek Formation.
