The Dinoroarus Experience

Dinoroarus is a seasonal exhibit. It will continue at the Zoo while the Zoo reimagines and redevelops the approximately 3-acre area into a new, permanent family and children's area, which will continue the Zoo's mission of connecting families and children with animals.

This engaging attraction for all ages features 14 different groupings of animatronic and stationary dinosaurs — colorful, prehistoric creatures that move realistically, some roaring and spitting or placidly munching on the lush vegetation. The dinosaurs and other ancient species representing a vast span of geological time include: a euoplocephalus (yoo-plow-seh-fuh-luhs), a life-size triceratops (tri-SERR-uh-tops), 12-foot-tall tyrannosaurus rex (tie-RAN-oh-SORE-us REX), giant stork-like quetzalcoatlus (ket-zel-KWAT-lus), an 18-foot-tall brachiosaurus (brack-ee-oh-SORE-us), nest of duck-billed parasaurolophus babies (PAR-ah-saw-RAH-lo-fuss) and many more. Plus, observe a staged fossil dig site and learn all about fossils.

New features of this exhibit include a never-before seen dinosaur euoplocephalus, the Dino Play playground, the Dino Dig with multiple digging opportunities, an animal space with North American river otters, and more!

Other live animals to meet include fish, moon jellies, sea stars, urchins, sponges, coral and anemones.
