Orangutan, Borneo (USNM 145301)

Orangutans are great apes and one of our closest living relatives. The Smithsonian Institution’s Division of Mammals ( houses many orangutans in its scientific collections.

This specimen, USNM 145301, is a male orangutan from the island of Borneo, Indonesia (Pongo pygmaeus).  It was collected by W.L. Abbott in 1907 near the Samandong River. The male weighed 200 lbs and measuring 1410 mm in total length. The hind tarsus length measured at 355 mm with a head to body length of 957 mm.

This is a CT scan of the cranium of USNM 145301. 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 (  

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.
