Gibbon, Indonesia (USNM 143570)

USNM 143570

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

This specimen, USNM 143570 (, is a female Sumatran Lar gibbon (Hylobates lar vestitus) from the island of Sumatra, Indonesia. This individual was collected by William Abbott in 1905 at Aru Bay. The specimen weighed 11.75 lbs and a head to body length of 460 mm.

This is a CT scan of the cranium of USNM 143570. 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 (, 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.
