Primeval Whirl was a steel Wild Mouse roller coaster at Disney's Animal Kingdom at the Walt Disney World Resort. The ride was a spinning roller coaster purchased from Reverchon Industries. The ride was part of Chester and Hester's Dino-Rama, which is itself part of DinoLand U.S.A. It was a roller coaster in the "Mild But Wild Thrills" category. It had cars that spun in circles while traveling on tracks, permitting the ride experience to vary greatly each time it is ridden. The ride featured 13 cars, each seating up to 4 riders. Disney demolished the ride track and a majority of the buildings used for the ride in late 2021.
