"Jurassic Park" was the first game by Sega to be developed using Silicon Graphics computers at the company's new development facility; such computers were previously used to create computer-generated dinosaurs for the film. The 3D models for the game's dinosaurs were created using stop motion photography while a team member was filmed acting out Grant's movements and was then digitized. Many dinosaur models used for the film were sent to the game's development studio so they could also be filmed and digitized while in motion. A $75,000 "Velociraptor" puppet from the film was also used for production of the game. The game features "Artificial Dinosaur Intelligence" that causes the dinosaur enemies to react differently every time a level is played, giving the player a unique experience each time.
