Indochinese Black Langur, Vietnam (USNM 240489)

USNM 240489

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 type specimen, USNM 240489 (, is a female Indochinese black langur (Trachypithecus ebenus) from Vietnam. This specimen was collected by F. R. Wulsin in 1924. In 1995, D. Brandon-Jones designated this individual the type specimen Semnopithecus auratus ebenus.

This is a CT scan of the cranium of USNM 240489. 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 relatives, the apes, available in 3D for education and research.
