Gibbon (USNM 542282)
Gibbons are apes and one of our closest living relatives. The Smithsonian Institution’s Division of Mammals (http://vertebrates.si.edu/mammals/) houses many gibbons in its scientific collections.
This specimen, USNM 542282 (http://collections.mnh.si.edu/search/mammals/?irn=7409949), is a male black crested gibbon (Nomascus concolor). This individual was donated to the collection by the Smithsonian National Zoo in 1971. This male weighed 11 lbs with a total length of 500 mm. The hind tarsus length was 153 mm while the ear notch length was 34 mm. The individual was about 9 years old at death.
This is a CT scan of the mandible of USNM 542282. 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.
