Eastern Potto, Democratic Republic of Congo (USNM 537770)
Lorises are primates and are more closely related to humans, apes, Old World monkeys and New World monkeys than any other living nonhuman primate group. The Smithsonian Institution’s Division of Mammals (http://vertebrates.si.edu/mammals/) houses many Lorises in its scientific collections.
This specimen, USNM 537770 (http://collections.mnh.si.edu/search/mammals/?irn=7405438), is a male eastern potto (Perodicticus potto ibeanus) from the Democratic Republic of Congo. This individual was collected in 1979 by C. B. Robbins near Tandala in Equateur Province. This individual weighed 1,050 g, had a total length of 440 mm, a tail length of 80 mm, a hind tarsus length of 75 mm, and an ear notch length of 28 mm.
This is a CT scan of the mandible of USNM 537770. 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.
