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.
Walk among modern-day dinosaurs as domesticated guinea fowl, a bird species, freely roam the exhibit area.
Other live animals to meet include:
- North American river otters
- Tasmanian devils
- Moon jellies
- Sea stars
Each animal has a story to tell about what they have in common with animals living at the time of dinosaurs.
"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."
