Because the Morian Hall of Paleontology is too large to tour in one evening, we are bringing back this popular series that covers the hall section by section with James Washington--now expanded to 6 sessions. All sessions are Wednesday evenings at 6:30 p.m. The Cretaceous Period brought us the most dangerous herbivore of all time, the mighty Triceratops. Learn how our triceratops specimen with mummified skin has helped science proves new information about these three-horned tanks. Our T. rex skeletons all tell a different story that helps piece together what life was like in the Cretaceous.
