The UMMAA Brown Bag Lecture Series is pleased to present a lecture by Dr. Joseph A.M. Gingerich, associate professor of anthropology at Ohio University, research associate at the Smithsonian Institution National Museum of Natural History, and a National Geographic explorer. Gingerich's lecture, Reconstructing Paleoindian Workspaces, will be held on Thursday, November 30, 12-1 p.m. in Room 2327 in the School of Education Building. He will present a detailed spatial analysis of the 13,000-year-old Shawnee-Minisink site in northeastern Pennsylvania, paying special attention to artifact metrics, microdebitage, and lithic refits to help classify activity areas. Detailed refitting and spatial analyses will offer new models for reconstructing activities at other mobile hunter-gatherer sites. Results of this study also reveal gender specific and domestic workspaces that provide new information on Paleoindian lifeways in the Americas. The Museum's Brown Bag Lecture Series is free and open to the public.
