John Hammond's narration claims that the Brachiosaurus was the "only true Jurassic native" of Jurassic Park. This is not true: Stegosaurus, which also appears in the game, was another Jurassic dinosaur, as well as Dilophosaurus and Compsognathus from the movies. He is also mistaken in labeling it the oldest dinosaur in the Park. Dilophosaurus lived tens of millions of years earlier.
