Orangutan, Sumatra (USNM 143594)

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 143594 (http://collections.nmnh.si.edu/search/mammals/?irn=7251579), is a male orangutan from the island of Sumatra, Indonesia (Pongo abelii). It was collected by W.L. Abbott in 1906 and weighed 120 lbs with a head to body length of 890 mm. The flash model of this orangutan radius is scaled to 50% in order to fit inside the viewer.

This is a CT scan of the right radius of USNM 143594. 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.
