A friendly looking dinosaur stands by while prospective riders on the Primeval Whirl roller coaster at Disney's Kingdom check to be sure they meet the minimum height requirement. I like the cute signage they use in and around the Dino-Rama section of the park.

Primeval Whirl is a spinning wild mouse coaster made by Reverchon. This coaster opened in March 2002 and has a total track length of just under 1400 feet. This 1 minute and 30 second ride produces up to 2.5 Gs, mostly due to the random spinning nature of the ride. It's never quite the same ride twice!
