First let's appreciate it. Making a science fiction movie using advanced techniques in 1993 really needs some guts. Making a science fiction movie on dinosaurs in 1993 which would also be the first of it's kind needs bigger guts. But having guts is partially acting stupid. The Jurassic Park precisely did that and gave a chance to the internet to kick some ass. So ahead of the series' newest installment, here are the best of the factual mistakes from it's older parts about it's very subject - the dinos.
The Spinosaurus and the T-Rex in Jurassic Park are shown without throat curves and are given back plates instead, which is contradictory to the reality, and quite funny.
In the conversation between Billy and Grant, the Suchomimus is said to be smaller than the Baronyx which is actually false because the Suchomimus was larger than the Baronyx.
Actually the Velociraptor used to claw it's victim in the neck. Also it could not eviscerate it's victim as the movie depicts.
In reality Velociraptor fossils have been found only in Asia. Montana is not even remotely associated to Velociraptors.
The Pterandons could never pick up people with it's feet because it was practically impossible for the dinosaur.
Its like they're suggesting the Pteranodon's relation to a bird which is sheer shit. The Pteranodon could never land like that on a damn branch.
Pteranodons never had teeth and in fact, the name itself means, wing without teeth.
There is no evidence for the fact that the Dilophosaurus could do such a thing to paralyze it's victims.
In the embryo freezing chamber, Tyrannosaurus rex is spelled as Tyranosaurus rex whereas Stegosaurus is spelled as Stegasaurus.
When Grant asks doctor Wu what species he is holding, she says it's a Velociraptor when actually, Velociraptor is a genus and not a species.
