Futureproof with Jonathan McCrea
The K-T boundary, a layer of debris, ash, and soot in the Earth’s sediment and about the thickness of a notebook - marks the dividing line between the Cretaceous and Paleogene periods. This line may not look like much to you or I, but to paleontologists it could contain the answers to some of the most burning questions surrounding one of the most significant events in the history of life on Earth - the day the dinosaurs died. Dr. David A. Burnham - paleontologist from University of Kansas, Natural History Museum, and Biodiversity Institute joins Jonathan to discuss the wealth of incredibly preserved fossils discovered at a site in North Dakota, and how they can tell us just what it would have been like the day the asteroid which wiped out the dinosaurs struck Earth.
