Ornate Spider Monkey, Panama (USNM 336202)

USNM 336202

New World monkeys are primates and are more closely related to humans, apes and Old World monkeys than any other living nonhuman primate group. The Smithsonian Institution’s Division of Mammals (http://vertebrates.si.edu/mammals/) houses many New World monkeys in its scientific collections.

This specimen, USNM 336202 (http://collections.nmnh.si.edu/search/mammals/?irn=7312674), is a male ornate spider monkey (Ateles geoffroyi ornatus) from Panama. This individual was collected by G.W. Barrett, Sr. in 1963 near Rio Changuinola in Bocas del Toro province. This specimen measured a total length of 1198mm, with a tail length of 710mm, a hind tarsus length of 177mm and an ear notch length of 37mm.

This is a CT scan of the cranium of USNM 336202. 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.
