Gibbon (USNM 545009)

USNM 545009

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 545009 (, is a female hoolock gibbon (Bunopithecus hoolock) named “Barbara”. This individual was born in 1944 and died the same day she was collected in 1982.  The total length is 460 mm, the hind tarsus length is 145 mm, and the ear notch length is 40 mm.

This is a CT scan of the mandible of USNM 545009. 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.
