Langur, Myanmar (USNM 277618)

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 specimen, USNM 277618 (http://collections.mnh.si.edu/search/mammals/?irn=7296158), is a female Shortridge’s langur (Trachypithecus shortridgei) from Myanmar. This individual was collected by Kenneth E. Stager in 1945 near Myitkyina District of Kachin Province. The total length of the individual was 1538 mm, the tail length 950 mm, the hind tarsus length 200 mm, and the ear notch length 34 mm.

This is a CT scan of the cranium of USNM 277618. 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 nonhuman primate relatives available in 3D for education and research.
