Even better than that, this movie ADVANCED our best understanding of dinosaurs at the time. They were blowing out a budget bigger than anything Hollywood had ever seen, and along with employing almost the last hurrah of incredible physical FX, they had a bank of those newfangled digital SFX computers. Nobody’d ever really created convincing dinosaurs in a movie before. It’d all been stop-motion animation, and even when the models were exquisitely crafted, you could just tell there was something OFF about them. Spielberg wanted THE BEST DINOSAURS EVER, and he figured on using the cutting edge of digital modeling and animation technology to build them for him.
So they got hold of some of the best paleontologists they could find and said, “We want you guys to take this tech that your labs could pretty much never afford and use it to build us the most realistic, accurate dinosaur models the world has ever seen.”
The paleontologists knew an opportunity when it bit them in the ass. They plugged in everything they knew about dinosaurs, all the skeletons and their best guesses about soft tissue and all that. And when they’d created those dinosaur models, they had the computer start moving them as they realistically would with anatomy like that. One guy took a look at those walking t-rexes and velociraptors (really utahraptors, but whatevs, fam), and he said, “Wait a minute, I’ve seen movement like that before.”
He called up film of a chicken walking. Everyone in the room said, “Holy shit.”
Prior to 1989, the idea that birds were descended from dinosaurs existed–we knew about archaeopteryx, we knew there was some minor connection there–but the idea that DINOSAURS LIVE IN THE MODERN WORLD AND THEY ARE CALLED BIRDS was not pre-eminent. Jurassic Park changed our scientific understanding of dinosaurs.
