13 Staggering Scientific Inaccuracies in the Jurassic Park Franchise

January 17, 2022

Jurassic Park is responsible for many ‘90’s kids’ obsession with dinosaurs. However, it also perpetuates a number of scientific inaccuracies which eventually frustrate those same dino kids.

13

Spinosaurus Was A Pescatarian CRACKED.COM Jurassic Park III featured a Spinosaurus, a large carnivorous dino with a sail on its back, that killed a T. Rex.

Rex. — Source

T. Rexes

T. Rex Wasn't Quick On His Feet CRACKED.COM When Jurassic Park was created in 1993, there was a common misconception among paleontologists that a T. Rex could run up to 40 mph.

Dilophosaurus Couldn't Spit Venom VS CRACKED.COM In one of Jurassic Park's most iconic scenes, a Dilophosaurus assails a nefarious character by spitting venom at him, leading to his demise. Unfortunately, there is zero fossil evidence to support this spit superpower OR the multi-colored neck fan it uses in the movie to stun its victim. However, Dilophosauruses had a ridge of feathers down the back of its head. — Source

Pterosaurs Couldn't Carry People CRACKED.COM In Jurassic World, Pterosaurs - a flying reptile, NOT a dinosaur - abduct and fly away with unsuspecting humans. However, it is unlikely that Pterosaurs would have been able to pick up and carry people heavier than their body weight while maintaining flight. Additionally, the Pterosaurs are portrayed flying like smaller birds when, in reality, they would more closely resemble larger birds, which require a running start or use air currents to start their flight. — Source

Mosasaur Is Too Damn Big CRACKED COM In Jurassic World, a Mosasaur-a swimming reptile, NOT a dinosaur-was portrayed in a sea-world like atmosphere, consuming a great white shark. HOWEVER, the prehistoric aquatic reptile in Jurassic World is twice the size of the largest Mosasaur fossil. However, the movie did get one aspect of the Mosasaur's anatomy right: it showed the Mosasaur's palatal teeth, a second set of chompers, similar to snakes and lizards, to hold their prey. — Source

Triceratops Wouldn't Have Gotten Sick CRACKED.COM Early in Jurassic Park, the group takes a detour to tend to a sick Triceratops who may have swallowed poisonous plants growing near the small stones, or gastroliths, they swallowed to crush and mash food in their stomachs. However, Triceratops had square and blocky teeth and, based on studies of the jaws and muscles surrounding their skulls, could likely chew his own food and likely had no use for gastroliths. — Source

4

Dinos Had Feathers CRACKED.COM When Jurassic Park came out in 1993, scientists didn't know that dinosaurs had feathers. Thus, when they began producing the second Jurassic Park movie, they couldn't give dinos feathers because it would create a consistency problem. However, it is now widely believed in the paleontological community that, just like all mammals have some hair, all dinosaurs had feathers. — Source

Velociraptors Were Real-Life Dino Nuggets GRACKED.COM Velociraptor Deinonychus Utah Rapto Unlike Spielberg's 6-foot-tall Velociraptors, the sickle-clawed Velociraptor was actually closer to the size of chickens.

T. Rex Could See For Miles & Miles RASSI CRACKED.COM In Jurassic Park, when T. Rex escaped from his cage, Dr. Alan Grant told everyone to be completely still because the T. Rex's vision was based on movement. If Jurassic Park had been real, this misconception would've gotten everyone killed.
