If dinosaurs didn't actually look like how we perceive and looked completely different, then the jurassic Park movies would look very dumb. amirite?

They're just guessing when it comes to colouring, but there's a lot of evidence of what kind of skin they had, their general appearance, etc.

Yeaaaaaaaaa
