Dinosaur is a dark ride EMV attraction at Disney's Animal Kingdom in Walt Disney World, Lake Buena Vista, Florida. The ride features a turbulent journey through the late Cretaceous period, featuring prehistoric scenes populated with dinosaur audio-animatronics. Originally named Countdown to Extinction when the park opened on April 22, 1998, the ride's name was changed to Dinosaur in 2000 to promote the Disney animated feature film of the same name, while it is revealed that the attraction was became part of Dino Institute. 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.
