Dental Microwear Lab

The Dental Microwear Laboratory in the Department of Anthropology at Georgia State University is curated by Dr. Frank L’Engle Williams. The Dental Microwear Laboratory houses a unique collection of dental impressions (n = 375), including specimens referred to fossil Parapapio, Papio, Theropithecus, Gorgopithecus, Dinopithecus, Cercopithecoides and Australopithecus as well as modern primate comparative material from Papio, Theropithecus, Colobus, Procolobus, Alouatta, Cebus, Pongo, Pan and Gorilla. The Dental Microwear Laboratory hosts two stereomicroscopes each equipped with an external movable light source and an ocular reticle to sample the occlusal surface for evidence of use-wear scars. A digital library of occlusal surfaces and statistical tools are also available to researchers and students to address the biochronology and paleoecology of Plio-Pleistocene southern Africa and Eurasia.

Dr. Williams received additional training in dental microwear using white-light confocal microscopy and Scale-Sensitive Fractal Analysis at the Department of Anthropology, University of Arkansas. A number of publications, presentations and theses have arisen from work in the Dental Microwear Lab.
