Closed for the season. Dinoroarus will reopen in spring 2022.

Dinos & More

This engaging attraction for all ages features 16 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:

  • 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)
  • 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.

Connections to Living Animals Today

Along the tropically planted trail in this land before time, discover the amazing connections between dinosaurs and living animals today. Learn fun and interesting facts about dinosaurs and the information scientists have gained from their fossils, theories on their mass extinction, and practical ways you can help protect animals today from going extinct.

"Dinoroarus gives us a chance to talk about difficult topics like extinction and how some predecessors of dinosaurs, including turtles and crocodiles, are still with us, as well as how some descendants of dinosaurs, like birds, still grace our lives," said Michael Macek, Director, Saint Louis Zoo.

Modern-Day Dinos

Each animal has a story to tell about what they have in common with animals living at the time of dinosaurs. 

Animals to see include:

Later this summer, domesticated guinea fowl will arrive. These birds — modern-day dinosaurs — will freely roam the exhibit area.

"Learning about dinosaurs is kind of like 'CSI,' using really old evidence," said Macek. "Paleontologists ask questions about why certain dinosaurs moved to different places and why their food supplies or habitats were threatened. And those are exactly the kind of questions Zoo conservationists ask today in trying to save animals from extinction."
