Explore the fascinating aftermath of the Cretaceous-Paleogene extinction event in this 55-minute lecture from the Royal Tyrrell Museum Speaker Series. Delve into how the K/Pg extinction wiped out the dinosaurs and paved the way for mammalian dominance. Examine the evidence for extraterrestrial impact and Deccan volcanism as potential causes of the mass extinction. Investigate the Hell Creek Study System and its importance in understanding the K-Pg boundary. Analyze fossil records and geological data to trace the ecological diversification of mammals following the extinction event. Compare endangered species today to the ecological disturbances of the late Cretaceous period. Discover the methodological approaches used to study dental complexity across the K-Pg boundary and its implications for understanding mammalian evolution. Gain insights into the winners and losers of this pivotal moment in Earth's history, presented by Greg Wilson from the University of Washington, Seattle.
