Gibbon, Laos (USNM 240493)

USNM 240493

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 240493 (, is a juvenile male northern white-cheeked gibbon (Nomascus leucogenys) from Laos.  It was collected in 1924 by F. R. Wulsin in Phongsaly Province.

This is a CT scan of the mandible of USNM 240493. 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.
