context_page_description: Harrington's mountain goat was a species of North American caprine that resided in the Southwest of the continent during the Pleistocene epoch. A relative of the modern mountain goat, which is the only existing species in the genus Oreamnos, O. harringtoni became extinct around 11,000 B.C.
context_section_description: Harrington's mountain goat was first described in the 1930s by paleontologist Chester Stock. Stock based his initial description on finds of skull fragments and metapodial bones from Smith Creek Cave in the Great Basin of Nevada. In 1937 he authored a Bulletin of the Southern California Academy of Science article titled "A new mountain goat from the Quaternary of Smith Creek Cave, Nevada". Later finds in Mexico, Colorado, Nevada, Utah, New Mexico, and the Grand Canyon have included intact skulls, metapodials, keratinous horn sheaths, dung, hair, muscle and ligament.
