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 598519 (,is a male Gabon talapoin (Miopithecus ogouensis) from Equatorial Guinea. This individual was collected in 1967 by Clyde Jones in Yabo near Rio Benito of Rio Muni Province. This individual had a total length of 705 mm, a tail length of 394 mm, a hind tarsus length of 97 mm, and an ear notch length of 24 mm. This specimen weighed 694.6 grams.

This is a CT scan of the mandible of USNM 598519. 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.
