Join us at the Cleveland Museum of Natural History for the kickoff event in our new lecture series, Science After Hours. In 1973, a young Jim Aronson, of Case Western Reserve University (CWRU), was invited to be the geochronologist for an exploratory project at Hadar, a site in the Afar Triangle of Ethiopia. Dr. Aronson, who had recently developed a system for dating minerals, joined project leaders Dr. Maurice Taieb, of France, and Dr. Donald Johanson, of CWRU and the Cleveland Museum of Natural History. In this talk, Dr. Aronson will take us on a journey to the site of significant fossil discoveries in Ethiopia, including Lucy and more.
