Macaque, Taiwan (USNM 296795)

USNM 296795

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 296795 (, is a male Formosan rock macaque (Macaca cyclopis) from Taiwan. This individual was collected by R. M. Dasch in 1953 near Kao-Hsiung (Takao). This individual had a total body length of 880 mm and a tail length of 390 mm. The hind tarsus length measured 340 mm and the ear notch length measured 31 mm.

This is a CT scan of the cranium of USNM 296795. 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.
