This presentation was given by Gerald Dinkins, Curator of Malacology, McClung Museum, and mussel expert, Steven A. Ahlstedt, at the 2010 Freshwater Mollusk Conservation Society workshop, held in St. Louis, Missouri. The purpose of the workshop was to was to provide participants with an overview of the mussel fauna within each ecological region in North America. In conjunction with the presentations, a “hands on” demonstration was given to small groups of attendants to the workshop, of the shells occurring in the Cumberlandian Faunal Region. Each participant was allowed to examine and handle representative shells (all were from the Paul W. Parmalee Malacological Collection at the Frank H. McClung Museum, University of Tennessee, Knoxville), and given a workbook describing in detail each species endemic to this region.
