White-Nosed Monkey, Ghana (USNM 435021)

Old World monkeys are primates and are more closely related to humans and apes than any other living nonhuman primate group. The Smithsonian Institution’s Division of Mammals (http://vertebrates.si.edu/mammals/) houses many Old World monkeys in its scientific collections. 

This specimen, USNM 435021 (http://collections.mnh.si.edu/search/mammals/?irn=7332445), is a male white-nosed monkey (Cercopithecus petaurista) from Ghana. This individual was collected in 1968 by C. J. Geest near Efeipo Krom in the Western Region. This individual had a total length of 1,080 mm, a tail length of 623 mm, a hind tarsus length of 128 mm, and an ear notch length of 32 mm.

This is a CT scan of the mandible of USNM 435021. These three-dimensional scans are made publicly available through the generous support of the Smithsonian 2.0 Fund, provided from the annual gifts of the Smithsonian National Board to the Secretary to use at his discretion (http://smithsonian20.si.edu/fund.html), and the Smithsonian Collections Care and Preservation Fund.

The main goal of this joint initiative between the Human Origins Program and the Division of Mammals is to make the NMNH's scientific collections of our closest living nonhuman primate relatives available in 3D for education and research.
