Jurassic Park Dinosaurs In Real Life

I Meme Everything

Ceratosaurus dentisulcatus

The Ceratosaurus in Jurassic Park III was too large, and was missing the two horns above its eyes.

Compsognathus longipes

The Jurassic Park franchise's Compsognathus has the main inaccuracy of a lack of feathers. And to my knowledge, there is no evidence to suggest that they swarmed their prey.

Dakotaraptor steini (IRL)/Velociraptor mongoliensis

The JP Velociraptor has the name of V.mongoliensis, the appearance (aside from the nakedness) of Deinonychus, and the size of Dakotaraptor. It wasn't found in Montana, which is where Alan Grant and Ellie Sattler found a specimen, it was located in Mongolia as the species says. Had the movie come out more recently, they should've just used Dakotaraptor steini. It lived in the Hell Creek formation and was the same size as the movie's raptors.

Gallimimus bullatus

The problem with the Gallimimus is the lack of feathers. Expect to see this inaccuracy in other dinosaurs mentioned in this post.

Giraffatitan brancai (IRL)/Brachiosaurus altithorax (JP)

The Brachiosaurus in the first Jurassic Park is way too large, and it couldn't rear up on its hind legs. The sauropod is basically a Giraffatitan.

Spinosaurus aegyptiacus

Probably the least accurate dinosaur in the franchise, Spinosaurus was very different from its Jurassic Park III counterpart in real life. It couldn't kill a T.rex and shouldn't have even been going after the humans on land. It was an aquatic dinosaur adapted for snaring fish. The shape of the sail was wrong, and its legs were much shorter.

Triceratops horridus

Although one of the most famous dinosaurs of all time (second to the next dinosaur in this topic), the Jurassic Park Triceratops had its inaccuracies. T.horridus was not that large, and it had quills on its hindquarters.

Tyrannosaurus rex

The most famous and iconic prehistoric animal of all time, the Tyrannosaurus rex in the Jurassic Park movies had its inaccuracies, but the real-life animal was even more terrifying. We now know that T.rex had both feathers and scales, so it should've had some form of feathering. In addition, its eyesight was not based on movement; it actually had acute binocular vision, so it should've eaten the humans.

Very interesting, DT.

Something Real

DRACONUS - This is a very compelling topic! I greatly enjoy the fact that you have presented both iterations of the animals you have chosen to display. Thank you ever so much for sharing this with us! :)

Few notes/comments:

I'm not certain how true this is, but I think Ceratosaurus didn't possess a true horn, but another crest.

There is little evidence of Gallimimus "flocking" like a bird.

Compsognathus is portrayed with two fingers instead of three. 

(Also, Trike having quills isn't confirmed nor denied as far as I know.)

I'd give the Spino a bit of a pass (along with the raptors) since quadrupedal Spino and feathered raptors were unknown to science at the time. However, there were still a plethora of inaccuracies in both of them, especially the wrists.

Other than those notes, I agreed with the list.

^It was me critiquing the JP dinosaurs. They were accurate for the time in which the movies were released.
