Sudamericidae is a family of gondwanathere mammals that lived during the late Cretaceous to Miocene.Its members include Lavanify and Vintana from the Cretaceous of Madagascar, Bharattherium (=Dakshina) from the Cretaceous of India, Gondwanatherium from the Cretaceous of Argentina, Sudamerica from the Paleocene of Argentina, and unnamed forms from the Eocene of Antarctica (closely related to Sudamerica) and Cretaceous of Tanzania. More recently, Patagonia, a mammal from the Colhuehuapian stage of the Miocene of southern South America, has been suggested to be a sudamericid.

Vintana is one of the most complete gondwanathere remains, and offers an insight to the anatomy and habits of sudamericids as a whole. It possesses massive lateral flanges in its skull, and bears massive olphactory bulbs. At a size of 20 pounds, it is one of the largest Mesozoic mammals known.
