Vertebrate Paleontology, Mammalian Biogeography, and Systematics

Timothy Gaudin, Ph.D.



Research Interests:

My primary research interests are in the systematics and morphological evolution of edentate mammals (including anteaters, sloths, armadillos, pangolins and related fossil forms). In addition, I am interested in the biodiversity and biogeography of living mammals in southeastern Tennessee. I am also working on a long-term project involving the recovery and analysis of Late Pleistocene vertebrate faunas from Lookout Mountain, TN, in order to better understand the historical biodiversity, biogeography, and paleoecology of southeastern Tennessee vertebrates.

Sample Grants/Projects

National Science Foundation RUI grant, Division of Environmental Biology, Systematic Biology program. Project: The early evolution of the Pholidota and a reexamination of the monophyly of the cohort Edentata (Mammalia). (2001-2005)
