Explore the origin, evolution, and lives of dinosaurs in an interactive session live from the Smithsonian'€™s National Museum of Natural History. Students will participate in challenges and demonstrations as Smithsonian Curator of Dinosauria Matthew Carrano leads them through exhibits of the Triassic, Jurassic, and Cretaceous periods. Who were the first dinosaurs? What were dinosaur habitats like? How did they live, and why did they go extinct? Where are dinosaurs today? And how do paleontologists learn about these amazing ancient animals? Find out answers to these questions and many more as the Smithsonian dinosaur hall comes to visit you.
