Langur, Nepal (USNM 290066)

USNM 290066

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 290066 (, is a male Tarai gray langur (Semnopithecus schistaceus hector) from Nepal. This individual was collected by S. D. Ripley in 1949 near Chatra in East Nepal. This individual had a total body length of 1169 mm and a tail length of 905mm. The hind tarsus length measured 195 mm and the ear notch length measured 50 mm.

This is a CT scan of the mandible of USNM 290066. 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.
