Central Potto, Equatorial Guinea (USNM 598479)

Pottos are primates and are more closely related to humans, apes, monkeys, lemurs, lorises and tarsiers than any other living nonhuman primate group. The Smithsonian Institution’s Division of Mammals ( houses many pottos in its scientific collections. 

This specimen, USNM 598479 (, is a female central potto (Perodicticus potto edwardsi) from Equatorial Guinea. This individual was collected in 1967 by Clyde Jones near Eyamoyong in Rio Muni Province. This individual had a total length of 370 mm, a tail length of 56 mm, a hind tarsus length of 68 mm, and an ear notch length of 22 mm. This specimen weighed 938.6 grams.

This is a CT scan of the mandible of USNM 598479. 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.
