Another day, another lie from Hollywood. Inaccuracies in the Jurassic Park movies abound, and the biggest scientific errors glare at you with the intensity of a T.rex staring down two kids trapped in a car. As crazy as it sounds, Steven Spielberg never tackled the film with the intent a National Geographic-worthy film. From the original movies and pre-glam Laura Dern to Bryce Dallas Howard running from a dinosaur in heels (seriously, when will women in movies wear reasonable shoes?), the popular film saga takes plenty of artistic liberties when it comes to even the simplest dinosaur facts. The biggest scientific errors in Jurassic Park sound surprising, until you recall most sci-fi movies employ bad science.
The Jurassic Park series plays the same game, adding traits to dinosaurs that range from bada** (venom spitting) to bizarre (sneezing). But inaccuracies in these films include more than just what Jurassic Park gets wrong about dinosaurs; their "rules" on fossils and genetics unravel faster than strands of DNA encased in amber (yep, even the insects lied in this film). But don't let the Jurassic Park movies's sci-fi lies get you down. The world will always have Chris Pratt's abs... unless those were CGI, too.
Spielberg Basically Created An Entirely New Dinosaur With The Velociraptors
The velociraptor stands as possibly the most famous dinosaur in the Jurassic Park franchise. From terrorizing kids in the classic kitchen scene to becoming Chris Pratt's BFF's in Jurassic World, the raptors go through enough character developments that some executive probably proposed a raptor spin-off called Jurassic Park: Enter the Dino.
Sadly, pretty much all of Spielberg's ideas about the raptor hold little to no scientific ground. Velociraptors grew to be about the size of a turkey, weighing in around 30 pounds. Continuing with the avian themes, the raptors should appear to be more bird-like and sport some feathers. And though they ate meat, they were not ferocious killers. At 30 pounds and the size of a turkey, the raptor would not live up to the agility they display in the films. Their top speed likely clocked in around 40 miles per hour - still fast, but not fast enough to be racing alongside Chris Pratt and his motorcycle.
The T. Rex Could Never Chase You
One new detail in particular makes the T. rex much less terrifying... and makes the Jurassic movies even more ridiculous. According to science, if the T. rex ran as quickly as it does in the movies, it legs would break under its body weight. Not cool, bro, especially since those stubby arms would never break a fall either.
Scientists with nothing better to do used some fancy computer modeling to discover "that true running gaits would probably lead to unacceptably high skeletal loads in T. rex." So, instead of traipsing around at 45 miles an hour, the T. rex likely ran around a speed of five-to-15 miles per hour. You could have escaped!
The Triceratops Poop Was Not Realistic
Before Laura Dern became classy as all hell in Big Little Lies, she dug through Triceratops poop in Jurassic Park. Talk about coming a long way, huh folks?
However, the pile of poop is big, like the size of the dinosaur itself. Despite Ellie Satler's willingness to plunge her arm into poop, a true expert knows this prehistoric feces are a pile of BS. If you want to see what prehistoric poop really looked like, check out some pictures of coprolites (the fancy name for fossilized crap) here. Sadly, no coprolites ever matched the size of dinosaurs.
One of the original producers, however, tells debunkers to "get a life." The guy has a point.
All The Dinos Are Missing A Key Feature: Feathers
A noticeable problem in all of the Jurassic movies would be that none of the dinosaurs are shown with feathers. Recent evidence excavated in Siberia suggests all dinosaurs, not just some, sported feathers. A two-legged dinosaur fossil dating back to 160 million years ago in the Jurassic period indicates that feathers existed in more than just avian-like/winged dinosaurs; it's more likely that feathers existed much longer than previously thought. The fossils turned up in what used to be a lake bed; ash from volcanic eruptions preserved their skeletons as well as their feathers. To be fair, the Siberian fossil turned up two decades after the first film, so this gaffe can slide a little bit.
