Scientific classification

Gondwanatheria is an extinct group of mammals that lived during the Upper Cretaceous to the Miocene. They lived in the Southern Hemisphere continents which had been part of the supercontinent Gondwana.[1]

These mammals are known only from isolated teeth and a few lower jaws. Because of these fragmentary remains, their relationships are unclear. Later finds have improved our knowledge of them.[2] It was thought previously that climate changes at the Eocene–Oligocene boundary had caused their extinction.[3]

Fossils have come from South America, India and Antarctica, where gondwanatherids lived in the lush forests which once covered much of the world.
