Howler Monkey, Panama (USNM 290699)

USNM 290699

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 ( houses many New World monkeys in its scientific collections. 

This specimen, USNM 290699 (, is a male Azuero howler monkey (Alouatta coibensis trabeata) from Panama. This individual was collected in 1950 by H. C. Clark near the Azuero Peninsula, located in the Herrera Province.

This is a CT scan of the mandible of USNM 290699. 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 (, 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.
