Orangutan, Sumatra (USNM 143593)

USNM 143593

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 143593 (http://collections.mnh.si.edu/search/mammals/?irn=7251578), is an adult male orangutan from the island of Sumatra, Indonesia (Pongo abelii) that was collected by W.L. Abbott at Aru Bay on January 23rd, 1906. This adult male weighed 160 lbs with a head to body length of 965 mm. While standing, the male measured 1400 mm tall.

This is a CT scan of the mandible of USNM 145393. 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.
