Step into the world of prehistoric predators and plant eaters where you're the paleontologist. Over a dozen full size dinosaurs roam Edward St. John Hall—home to Dinosaur Mysteries. Walk under, over, and through a landscape filled with dig pits, a field lab, excavation sites, and other areas of discovery.

Meet T. rex and Astrodon—just two of the huge residents in the massive, open hall. Full size skeletons and casts of fossilized remains are on display and everything is hands-on. Touch a triceratops skull. Grab a brush and work side by side with other dinosaur hunters. Pick up a set of calipers and measure the length of dinosaur leg bones. Stand in a footprint in the dinosaur trackway. Sit in a nest of dinosaur eggs. Listen for the roar of a lumbering giant.

Live animals including amphibians and lizards help explain the connection between past and present. And find out why scientists think birds and dinosaurs are linked through the passage of time.
