Orangutan, Borneo (USNM 153821)

Orangutans are great apes and one of our closest living relatives. The Smithsonian Institution’s Division of Mammals (http://vertebrates.si.edu/mammals/) houses many orangutans in its scientific collections.

This specimen, USNM 153821 (http://collections.mnh.si.edu/search/mammals/?irn=7255015), is a female young adult orangutan from the island of Borneo, Indonesia (Pongo pygmaeus).  It was collected by W.L. Abbott in 1908 near the Kendawangan River in Upper Parui. The female weighed 76 lbs with a head to body length of 740 mm. The hind tarsus length measured at 270 mm.

This is a CT scan of the mandible of USNM 153821. 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.
