Chimpanzees are great apes and one of our closest living relatives. The Smithsonian Institution’s Division of Mammals (http://vertebrates.si.edu/mammals/) houses many chimpanzees in its scientific collections.
This specimen, USNM 481803 (http://collections.mnh.si.edu/search/mammals/?irn=7360749), is a female chimpanzee (Pan troglodytes) from Liberia. This individual was collected by D. A. Schlitter near Tars Town in Grand Gedah Province. The specimen weighed 110 lbs and had a total length of 850 mm. The hind tarsus length measured 250 mm and the ear notch length was 60 mm.
This is a CT scan of the cranium of USNM 481803.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.
