Collection Catalogs

Catalogs of select portions of the Academy's Anthropology collection have been produced over the years. Southwestern Indian pottery and jewelry, Coptic textiles, and Polynesian tapa cloth have all been featured.

Anthropology Research Projects

The Dikika Research Project (DRP) is a multidisciplinary endeavor that seeks to address key evolutionary questions pertaining to various aspects of the paleobiology of early hominins (early human ancestors) – as well as their culture and environments over the past ca. 4.0 million years.

Anthropology Collections

Our permanent research collection consists of more than 16,000 objects, most of which are ethnographic. Current strengths include holdings from the U.S. Southwest and the Pacific Islands, and basketry from California. Our searchable online database features the entire Anthropology collection, including digital images for every piece.

Hominin Cast Collection

The Department of Anthropology houses a collection of hominin fossil and comparative casts that are available for reference by visiting researchers and students.
