How Fossils Explain the Rise of Dinosaurs with Dr. Hans Sues

Meet Dr. Hans Sues, a paleontologist at the National Museum of Natural History. While you may be familiar with the asteroid strike 66 million years ago that ended the dinosaur reign, have you ever wondered what started it? Find out more about the mass extinction event 200 million years ago that opened the door for dinosaurs to dominate life on land. Join Hans Sues in exploring what else lived in the Triassic landscape and how the dinosaurs rose to prominence. Examine the fossil evidence that dinosaurs might not have diversified so much were it not for the cataclysmic event that ended the Triassic.
