Stephen Chester is a paleontologist primarily dedicated to improving our understanding of primate origins. He studies fossil mammals from the Late Cretaceous to the early Eocene with particular focus on two events that are very significant in mammalian and early primate evolution. The first is the Cretaceous-Paleogene extinction event 66 million years ago, which eliminated the non-avian dinosaurs, and represents the beginning of a major radiation of Paleocene mammals including plesiadapiforms. The second is the Paleocene-Eocene Thermal Maximum 55.8 million years ago, which was a major global warming event that marks the appearance of several modern groups of mammals including euprimates (primates of modern aspect), and is important for understanding the effects of global warming on mammalian evolution. He is currently co-leading annual expeditions focused on mammalian faunal composition across the Cretaceous-Paleogene boundary in the Hell Creek and Fort Union formations of North Dakota and Montana.
