Germain's Langur, Thailand (USNM 236627)

USNM 236627

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 (http://vertebrates.si.edu/mammals/) houses many Old World monkeys in its scientific collections.

This type specimen, USNM 236627 (http://collections.nmnh.si.edu/search/mammals/?irn=7282313), is a female Germain’s langur (Trachypithecus germaini germaini) from Thailand. This specimen was collected by C. B. Kloss in 1916 near Lat Bua Kao, located within Nakhon Ratchasima Province. In 1919, C. B. Kloss designated this individual the type specimen Presbytis cristata koratensis.

This is a CT scan of the mandible of USNM 236627. 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 (http://smithsonian20.si.edu/fund.html), 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.
