Most of the paleo-inaccuracies (if not all) in the Jurassic Park franchise can be blamed on one key factor: Frog DNA.
How can the dinosaurs change sex? Frog DNA.
Why could some dinosaurs roar? Frog DNA.
Why do all the theropods have "broken" wrists? Frog DNA.
Why do all the dinosaurs have some level of shrink-wrapping? Frog DNA.
Why was the dilophosaurus below its actual height? Frog DNA.
Why did dinosaurs like Gallimimus, Atrociraptor, and Velociraptor not have feathers? Frog DNA.
Why was the Tyrannosaurus' bite force so weak compared to its real life counterpart? Frog DNA.
Why did the Ankylosaurus lose to the Indominus Rex when it was strong enough to handle its own? Frog DNA.
Why did the JP tyrannosaurus have bad eyesight? Well in the book, its supposed to be frog DNA. In the movie, its exposition given by Dr. Grant.
Why did carnivorous dinosaurs around the height of T. rex hunt smaller prey even though gigantism should have prevented that? Frog DNA. Remember, frogs eat bugs which are much smaller than them.
Why does Baryonyx look nothing like its fossilized skeleton suggests? Frog DNA and possible crocodilian DNA.
Why were the Pteranodons so aggressive and featherless? Frog DNA.
Why is the JW & Rebirth Mosasaurus much bigger than it should be? I'm assuming Frog DNA. It is considered its own species.
Why was the JP3 Spinosaurus hyper-aggressive and very different compared to how it should be according to paleontology? Frog DNA, additional gene modifications, and because Dr. Wu and the other JP scientists didn't realize what the actual spinosaurus looked like, so the previous more paleo-accurate clones they made were discarded to Isla godknowswhere.
Why could dilophosaurus spit venom? Frog DNA...somehow. According to the Masrani Global website, Yellow-banded Poison Dart Frogs were the most compatible with Dilophosaurus DNA. So Frog DNA yes, but somehow that gave it the ability to shoot venom, and have frills.
How come Atrociraptor shares a similar height to Velociraptor Antirrhopus (aka Deinonychus)?...not Frog DNA but Isla Sorna Velociraptor DNA (I'm assuming the Tiger Stripes from TLW due to their aggression) which has frog DNA. Yeah these are hybrid raptors according to dinotracker.com. Although that is debatable considering BioSyn's dinosaurs are supposedly pure. But that would explain why they sound like raptors in Chaos Theory.
How come Pyroraptor exhibits traits of winter predators even though it likely didn't live in those conditions in the first place? I have no idea...BioSyn made these guys. Penguin DNA I assume?
But things such as the velociraptors being tall, smart, pack hunters, are attributes from deinonychus. And Velociraptor is deinonychus, or at least it is in the books. Long story short, Velociraptor antirrhopus is the full species name for the book version of the raptors, not Velociraptor mongoliensis. This is because in the book universe, deinonychus is considered velociraptor, and not its own genus. Thank you, Michael Crichton for making Velociraptors 10x more confusing than needed to be. I don't think Deinonychus was that intelligent and they only formed packs sometimes to take down larger prey
Other than that issue, most dinosaurs in Jurassic Park have some level of difference compared to their real life counterpart. Hope this helps some people who get upset everytime a dinosaur, flying reptile, or other prehistoric creature is shown with inaccurate details in this franchise. And please note that several types of frogs may have been used in the creation of these dinosaurs. Just because Dilophosaurus had DNA that was most compatible with that of a poison dart frog's doesn't mean the Reed Frog (the african frog that Dr. Grant theorized the JP scientists were using) wasn't used in dilophosaurus' modified genome.
