Dr. Matt Heizler and Dr. Bill Mclntosh host a discussion about the practical aspects of Argon Geochronology.

This is part of the paleontological discussion at the Corral Bluffs planning meeting held on April 1, 2008. The discussion is with Dr. Kirk Johnson, Vice President of Research & Collections and Chief Curator of the Denver Museum of Nature and Science on the paleontological resources and value of the Corral Bluffs area. Dr. Kirk Johnson joined the Museum in 1991 after earning his doctorate in geology and paleobotany from Yale University. He studies fossil plants, terrestrial stratigraphy, geochronology, and dinosaur extinction and has published many popular and scientific articles on topics ranging from fossil plants and modern rainforests to the ecology of whales and walruses. He is best known for his research on fossil plants, which is widely accepted as some of the most convincing support for the theory that an asteroid impact caused the extinction of the dinosaurs. Since 1997, he has supervised the Denver Basin Project, a multidisciplinary NSF-funded effort to understand and interpret the paleontology, geology, and hydrology of the rocks beneath Denver. This work has led to the discovery and analysis of a 64 million-year-old tropical rainforest in Colorado. His research has also taken him to Alaska's Bering Sea, the Brazilian Amazon, the Canadian High Arctic, the rainforests of New Zealand, the Gobi desert, India, China, Patagonia, and the American West. He is presently working on research projects in Patagonia, Manchuria, Wyoming, and Denver. http://www.SaveCorralBluffs.com http://www.dmns.org/main/en/General/Science/ScientificExperts/Biographies/Johnson+Kirk.htm

The genius "rickrocker" appears to believe science isn't good enough to know Earth's age. http://www.youtube.com/comment_servlet?all_comments&v=LdX3BzP08bE
