A Mix And Match Critter of a modern-day animal, and a prehistoric animal

Name Space:
Page Type:
A lot of works are set in 1 Million B.C.. 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. May also sometimes occur in modern-day set dramas involving mutated animals.

However, most writers 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 and "Xsaurus", "Saber-toothed X", "Xraptor" or "CaveX".

Funny Animal characters are usually neanderthals unless they are antagonists.

Note that this includes both portmanteaus or mix and match critters of a modern-day animal and a prehistoric animal. May intersect with Somewhere, a Paleontologist Is Crying.


Comic Books
  • The "Cave Cat" segment of Garfield: His 9 Lives shows Garfield as a saber-toothed housecat and Odie as a giant green saber-toothed dog.

  • A number of Syfy movies. Case in point: {{Dinocroc.}}
  • Insectosaurus from Monsters vs. Aliens.


Video Games

Web Comics
  • The title panel of this Garfield strip has Odie as a Dogasaurus.

Western Animation
  • The Flintstones sometimes makes vague references to creatures like a "chickensaurus"
  • Scrat from Ice Age is a saber-toothed squirrel. However, he is actually based on a Leptictidium.
  • The Future Is Wild features a saber-toothed wolverine, a caracararaptor, and a turtlesaurus (specifically named a snowstalker, carakiller, and toraton).
  • The Looney Tunes short Prehistoric Porky shows Porky to be descended from a cavepig, while Pre-Hysterical Hare shows Bugs to be descended from a saber-toothed rabbit.
  • The Tom and Jerry short Prehisterics has Tom as a saber-toothed housecat and Jerry as a cavemouse. During the short they encounter a giant saber-toothed rabbit.
  • The SpongeBob SquarePants episode "Ugh" has Spongebob, Patrick, and Squidward as a cavesponge, caveoctopus, and cavestarfish, with Gary as a giant snailsaurus.
  • Dino Squad has many examples. Most of the mutated creatures created by Victor Veloci were mutated mixes of modern day and ancient creatures. Only the Dino Squad were 'perfect' creatures.
  • The Phineas and Ferb episode "The Tri-Stone Area" has Perry as a saber-toothed platypus.
  • The catsaurus and catdactyl on Bling-Bling's Island on Johnny Test.

Real Life
  • In reality, many prehistoric animals seem like this. For example, ceratopsians (rhinosauruses), pterosaurs (batsauruses), ichthyosaurs (dolphinsauruses), ornithomimids (ostrichsauruses), Dinofelis (saber-toothed leopard), etc. Subverted since they aren't ancestors of the similar modern-day creatures.

    • The Sponge Bob Square Pants episode "Ugh" shows caveman versions of SpongeBob, Patrick and Squidward. Gary was a giant snailsaurus, while Mr. Krabs' ancestors were tiny crabs that only say "money" and are eaten as food by the other characters.

    Some shows will depict FunnyAnimals as Neanderthal-like, regardless of what the prehistoric ancestor of the actual animal would look like.

    Image should be the puppisaurus from Science Made Stupid, unfortunately I don't think there are any images from that book floating around...

    Here's your image: quoteright:300: Puppisaurus

    Science Made Stupid was a book that parodied children's science books. The puppisaurus was in a sidebar about mammal-like reptiles (an actual type of creature that, of course, did not really include a puppisaurus). I probably ought to make a page about it.

    I'm pretty sure the ones I added basically fit, even though they're not ancestry ones. Variations, I'd call them. However, if they don't, delete at will.

    Insectosaurus from Monsters Vs Aliens. Along with his massive size, he also has a dinosaur's feet and tail. Not prehistoric, however, but mutated from a nuclear explosion.

    ^ and ^^ The trope is about made-up mixes of modern and prehistoric animals because of the need for an ancestor of the character. I'd call those example played with or inverted.

    • Aerodactyl from Pokemon is a mix of a gargoyle and a pterodactyl.

    ^ I don't think that works. That's just naming his discovery after himself.

    Does Scrat count as an example. He's a saber-toothed squirrel.
  • November 13, 2012
    ^Scrat is on the list.

    The giant dinosaur-like critter called a mythosaur is the national animal of Mandalorians (from the Star Wars Expanded Universe). Their emblem is a mythosaur skull.

    The After Man and Future is Wild examples probably qualify as inversions, as their Whateversaurus creatures are from the distant future rather than the past.

    From Everything's More Prehistoric With Saberteeth YKTTW: Basically says about how sometimes people will put sabre teeth on a character or animal to show that it is prehistoric or looking like it is from a prehistoric time (best example would be Scrat from Ice Age).

    ^^^ Not a hybrid.

    ^^ I originally counted them as inversions, but then the definition was modified to include works set in the present day.

    ^ This seems to be a more general version of that.
