Fossil Primates and Paleoecology

Research

In 1988 a peculiar skeleton was brought to me while serving as Collection Manager of Fossil Mammals at the American Museum of Natural History in New York. Since my academic training was in physical anthropology, I recognized this 49 million year old specimen to be one of the most complete fossil primates ever found in North America. This skeleton lead me to change my masters thesis from an analysis of the Folsom Bison Quarry to a description of the facial skeleton of the Eocene primate Notharctus. I have I have conducted an ongoing field research project in the Bridger Basin of southwestern Wyoming since1991. During that period I have discovered and prepared more Eocene primate skeletons than any other person alive. In the process of looking for these ancient lemurs, I have become familiar with the entire Bridgerian fauna from tiny ground-nesting bees to huge extinct crocodiles. In recent years I have had the privilege of collecting many such specimens for the Burke Museum paleontology collection.
