Sudamerica

Description

Sudamerica, literally "South America" in Spanish, is a genus of mammal from the extinct suborder Gondwanatheria that lived in Patagonia, Argentina (Salamanca Formation) and Antarctica (La Meseta Formation) from the Middle Paleocene (Peligran), just after the end of the "Age of Dinosaurs", to the Early Eocene (Casamayoran).
