Weeks Lecture, presented by Darin Croft, Case Western

South America as a whole has an excellent fossil record of Cenozoic mammals. This has formed the basis for a good general understanding of major patterns of mammal evolution on the continent over the past 65 million years. Nevertheless, most of what is known about Paleogene and early Neogene mammals comes from a limited area in southern Argentina. As a result, a primary goal of many paleomammalogists working in South America is to broaden geographic and temporal sampling during this interval.
