USNM 477331

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 ( houses many Old World monkeys in its scientific collections. 

This specimen, USNM 477331 (, is a male olive colobus monkey (Procolobus verus) from Cote d’Ivoire. This individual was collected in 1969 by L. W. Robbins near Kahin. This individual weighed 10 lbs, had a total length of 1068 mm, a tail length of 603 mm, a hind tarsus length of 135 mm, and an ear notch length of 29 mm.

This is a CT scan of the mandible of USNM 477331. 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 (, 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.
