Langur, Indonesia (USNM 121654)

USNM 121654

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 121654 (http://collections.mnh.si.edu/search/mammals/?irn=7245536), is a female pig-tailed langur (Simias concolor) from the island of Sumatra, Indonesia. This individual was collected by William Abbott near the Sumatera Barat Province in the Mentawai Islands.

This is a CT scan of the cranium of USNM 121654. 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.
