The Vertebrate Paleobiology collections concentrate on Southwestern Pleistocene fossils, primarily from New Mexican cave faunas, although small numbers of other fossils are held. This catalogue includes specimens for which the UTEP Biodiversity Collections (UTEP-BC) acts as repository, both permanent and temporary. The UTEP-BC currently is repository for large numbers of specimens from lands of the Bureau of Land Management and sites under the jurisdiction of the Department of Defense. The primary focus is upon late Pleistocene Southwestern faunas, although there are some Holocene archaeological holdings and some Tertiary material as well. This emphasis primarily reflects the research interests of the curator, Arthur H. Harris, who has maintained and added to the collections since their initial organization in 1965.
