This journey to prehistoric times introduces you to the powerful monsters that once ruled the earth. Through the magic of animatronic technology, DINOSAURS! brings life to the 20-foot-tall Tyrannosaurus rex, the 30-foot-long Iguanodon, the fierce Deinonychus and the fish-hunting Baryonyx. The exhibit is $1 per person with regular zoo admission and free for children under 2. Dinosaurs! is open daily from May 21 through Sept. 13.
