In the attraction, guests board vehicles called Time Rovers and are taken on a turbulent journey through the Cretaceous period, featuring prehistoric scenes populated with audio-animatronic dinosaurs. Originally named Countdown to Extinction, the ride's name was later changed to DINOSAUR to promote the Disney animated film of the same name, even though the attraction has never contained any explicit references to the film. However, the two dinosaurs most prominently featured in the ride have always been an Iguanodon and Carnotaurus, which were both featured prominently in the film. Scenes from the movie also appear in the pre-show, to help the guests identify the Iguanodon as the film's protagonist, Aladar.
