White-Thighed Surili, Indonesia (USNM 123149)

USNM 123149

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 type specimen, USNM 123149 (http://collections.nmnh.si.edu/search/mammals/?irn=7246085), is a female white-thighed surili (Presbytis siamensis cana) from Indonesia. This specimen was collected by William Abbott  in 1903 near the Kateman River on the island of Sumatra. This individual weighed 14 lbs and was designated the type specimen of Presbytis catemana by M. W. Lyon in 1908.

This is a CT scan of the mandible of USNM 123149. 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.
