Dinosaur, formerly known as Countdown to Extinction, 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 film of the same name. 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. Ride experience Queue If the ride is busy, then guests will first wind though an outdoor area before entering the first section of the indoor queue. Once inside the first section, guests will see several small exhibits including a display of small fossils, modern animals that can be traced back to the dinosaur ages, and evidence for the several theories of mass extinction. The second section of the indoor queue is an eight-sided room, with the upper parts of the walls displaying some artist renderings of what the age of the dinosaurs might have looked like and some fossils. The lower sections of the walls are a simulation of sedimentary rock that contain fossils. Some sections of the lower walls have windows that display some more fossils. Hanging from the ceiling is a large globe with Pangaea, and a rod connected to the globe with measurements of hundreds of thousands of miles to show how far the theoretical asteroid that impacted with earth to cause mass extinction had to travel. The defining feature of the second room is its centerpiece: a Carnotaurus fossil. In the second room, at regular time intervals, the lights dim, and Bill Nye the Science Guy shares some facts and theories about the age of dinosaurs, using the globe, the paintings, and the fossil to help out with his small lectures. After weaving through the second room, guests then enter one of two pre-show theaters. Preshow Guests enter a small standup theatre and a short movie comes on a projection screen. The first part of the movie is a small presentation by the fictional director of the Dino Institute, Dr. Helen Marsh (played by Phylicia
