John Hunter, Associate Professor in the Department of Evolution, Ecology and Organismal Biology at the Ohio State Newark campus, discusses his research in the evolution, paleoecology, and biogeography of mammals and dinosaurs. He talks about his recently published research on duck-billed dinosaurs, where he studied roughly 75 to 80 million year old fossils found in Montana. Hunter also explains his focus on teeth within his research, elaborating on the unique and beneficial properties of teeth to paleontologists and what they can show us about how different animals lived and evolved.
