Orangutan, Borneo (USNM 142169)
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 142169 (http://collections.mnh.si.edu/search/mammals/?irn=7250995), is a female orangutan (Pongo pygmaeus) from the island of Borneo, Indonesia. This individual was collected by W.L. Abbott on June 18th, 1905 near Sungai Suma. The female weighed 70 lbs with a hind tarsus length of 1065 mm. The head to body length is 720 mm long.
This is a CT scan of the cranium of USNM 142169. 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).
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.
