Old World monkeys are primates and are more closely related to humans and apes than any other living nonhuman primate group. The Smithsonian Institution’s Division of Mammals (http://vertebrates.si.edu/mammals/) houses many Old World monkeys in its scientific collections.
This specimen, USNM 537776 (http://collections.mnh.si.edu/search/mammals/?irn=7405444), is a female greater spot-nosed monkey (Cercopithecus nictitans nictitans) from the Democratic Republic of Congo. This individual was collect in 1979 by C. B. Robbins near Yalosemba in Equateur Province.
This is a CT scan of the mandible of USNM 537776. 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 nonhuman primate relatives available in 3D for education and research.
