SudamericaSudamerica is a genus of mammals from the extinct suborder of Gondwanatheria, that lived in Patagonia, South America during the Paleocene, just after the 'Age of Dinosaurs'. Similar to Gondwanatherium, this genus had high-crowned teeth, which are very useful for grass-eating animals. Since there is no evidence of grass in South America until later, they must also have been effective for other food stuffs. Classification The type specimen of Sudamerica ameghinoi was discovered in Punta Peligro, Argentina in deposits dating to the lower Paleocene period. In 1999, a near complete lower jaw (dentary) was found. The genus and species were named by Svillszo-Yan and R. Pascual in 1984. The genus is also known by the synonym Sudamericana. The position of gondwanatherians within Mammalia is not yet clear. References - Malcolm C. McKenna and Susan K. Bell. (1997) Classification of Mammals Above the Species Level.
