Callithrix Monkey, Gambia (USNM 381445)

USNM 381445

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 381445 (, is a male Callithrix monkey (Chlorocebus sabaeus) from Gambia. This individual was collected in 1966 by R. M. Davis near Toniataba. This individual measured 1,260 mm in total length and 690 mm tail length. The hind tarsus length measured 142 mm long and the ear notch length measured 39 mm long.

This is a CT scan of the cranium of USNM 381445. 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.
