USNM 598534

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 598534 (, is a female Gabon talapoin (Miopithecus ogouensis) from Equatorial Guinea. This individual was collected in 1968 by Clyde Jones near Achimelang in Rio Muni Province. This individual had a total length of 570 mm, a tail length of 270 mm, a hind tarsus length of 92 mm, and an ear notch length of 20 mm. This specimen weighed 936.8 grams.

This is a CT scan of the cranium of USNM 598534. 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.
