Dr. Sharon Weaver, the curator at the Mammoth Site at Hot Springs, South Dakota, returns to the show to discuss megafauna with Jay.

Sharon holds a B.S. in Geology from South Dakota School of Mines and Technology, an M.S. in Geosciences from East Tennessee State University, and a Ph.D. in Biology from the University of Florida. Her Ph.D. dissertation was presented on 3D comparisons of the humerus, radius and ulna of modern carnivorans to early Miocene carnivorans. In the last couple of years, she has become more involved with cave paleontology and caving in general, leading to further research and education opportunities at The Mammoth Site.
