Primeval Whirl is a steel-spinning roller coaster at Disney's Animal Kingdom at the Walt Disney World Resort in Orlando, Florida. The ride is an "off the shelf" spinning roller coaster purchased from Reverchon Industries. The ride is part of Chester and Hester's Dino-Rama, which is itself part of Dinoland USA. It is a roller coaster in the "Mild But Wild Thrills" category of Disney Parks. It has cars that spin in circles while travelling the tracks, permitting the ride experience to vary greatly each time it is ridden. It usually seats up to 4 riders.
The ride is lightly themed, with decorations related to time travel and to the meteor which is believed to have caused the extinction of dinosaurs (Cretaceous-Teritary extinction event). This gives the coaster a storyline very similar to that of the nearby dark ride, DINOSAUR.
Fastpass is available for the ride.
