Introduction My research focuses on utilizing fossils to interpret past environments as well as to understand the relationship between mammalian evolution and climate change. To do this, I utilize stable isotopes and tooth wear analyses to determine the diets of extinct mammalian herbivores. These techniques also provide information about the local and regional environments. I am currently applying these methods to the hoofed mammals found in the John Day Fossil Beds in Central Oregon. These fossils range in age from approximately 25 to 7 million years ago.
