What is "sudamerica"

Sudamerica, literally " South America" in Spanish, is a genus of mammal from the extinct suborder Gondwanatheria that lived in Patagonia, South America during the Paleocene, just after the end of the " Age of Dinosaurs".

Similar to Gondwanatherium, this genus had high-crowned teeth, which are very useful for eating grasses. Since there is no evidence of grass in South America until later, they must also have been effective for other types of food.
