Northern Bearded Saki, Venezuela (USNM 406593)

USNM 406593

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

This specimen, USNM 406593 (, is a female northern bearded saki (Chiropotes satanas chiropotes) from Venezuela. This individual was collected in 1967 through the Smithsonian Venezuelan Project near San Juan in the Amazonas Province. This specimen weighed 2.3 kg, measured a total length of 780 mm, a tail length of 410 mm, a hind tarsus length of 120 mm, and an ear notch length of 29 mm.

This is a CT scan of the cranium of USNM 406593. 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.
