Landmark Analysis of Musteloid Carnassials Applied to Taxonomic Identification and Examination of Sexual Dimorphism and Regional Morphotypes
Guy Wilson Cave (GWC) in Sullivan County, Tennessee holds many late Pleistocene mammal fossils. Based on visual morphology, several partial mandibles with lower carnassial from GWC appeared to be musteloids. Geometric morphometrics has been successfully used to identify fragmentary fossils, so a lan...
