Red Howler Monkey (USNM 281667)
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 281667 (http://collections.nmnh.si.edu/search/mammals/?irn=7297240), is a female red howler monkey (Alouatta seniculus seniculus) from Colombia. This individual was collected by Hershkovitz in 1942 near El Salado, Cesar. This specimen measured a total length of 1,116 mm, a tail length of 643 mm, a hind tarsus length of 146 mm, and an ear notch length of 36 mm.
This is a CT scan of the mandible of USNM 281667. 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.
