Mammalogy Collection

About the Collection

Dr. Wilmot Thornton started the ASU Collection of Mammals in the mid-1960s. Dr. Mark D. Engstrom, now curator at the Royal Ontario Museum, served as curator from 1982-88. In that time, the collection moved to its current location in Room 109 of the Cavness Science Building.

Major expansions of the collection occurred during Dr. Engstrom’s tenure as curator. In 1988, Dr. Robert C. Dowler assumed the duties of curator and remains in that position today. Under his direction, the collection has reached more than 17,000 specimens.

The Collection of Mammals is accredited by the American Society of Mammalogists, Systematic Collections Committee. Almost half of the collection is of species from Texas. However, significant holdings are also represented from Mexico (3,600 specimens), Guyana (200) and the Galapagos Islands, seaward of Ecuador (300).

Recent field studies in Sulawesi, Indonesia and several U.S. states, including Arizona, New Mexico, Montana and Oregon, have added specimens to the collection.


Data for specimens in the Collection of Mammals is entered in a searchable database. Selected information from the database is searchable through our web interface. Although every effort is made to ensure the accuracy of catalogue information, researchers should verify information before use or publication. For additional information not provided through the searchable web interface, or if you have questions, please contact the curator.
