Proboscis Monkey, Indonesia (USNM 198277)

USNM 198277

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 198277 (, is a female proboscis monkey (Nasalis larvatus) from Indonesia. This individual was collected by H. C. Raven in 1913 near Sungai Baai River on the island of Borneo.

This is a CT scan of the mandible of USNM 198277. 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.
