MORE INFO Meet Dr. Kirk Johnson, a paleobotanist and Director of the National Museum of Natural History. See how he and other experts joined forces to figure out what happened at the end of the Cretaceous, 66 million years ago. While you may be familiar with the extinction of large dinosaurs, you might not realize that much of the other life on Earth went extinct as well. Join Kirk as he explores the extinction and recovery stories told by fossils found at the Hell Creek Formation in North Dakota. Examine evidence for the causes, the consequences, and the aftermath of the mass extinction for life on Earth.
