Emerson Dinoroarus

March 15-June 16, 2024

Dinoroarus is open for a limited engagement!

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. Guests of all ages will learn about what scientists can gather from fossils, theories of the dinosaurs' mass extinction and ways we all can support wildlife today!

Activities for all ages!

There is a massive area with new and old digging opportunities, including the Dino Dig, an exciting magnetic Dino Wall where guests can build dinosaurs and more engaging educational activities.

Modern-Day Dinos

Each animal has a story to tell about what they have in common with animals living at the time of dinosaurs. Meet animals that lived alongside dinosaurs, like moon jellies, fish, sea stars, urchins, sponges, coral and anemones.

Other Zoo animals to see include domesticated guinea fowl, a North American river otter.

Learning about dinosaurs is kind of like ‘CSI,’ using really old evidence. Paleontologists ask questions about why certain dinosaurs moved to different places and why their food supplies or habitats were threatened. Those are same questions Zoo conservationists ask today in trying to save animals from extinction.

The Future of Dinoroarus

Emerson 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.
