The discovery of new bones from a large land mammal that lived about 48 million years ago has led scientists to identify a new branch of mammals closely related to modern horses, rhinos, and tapirs.

This family of large mammals, Anthracobunidae, is only known from India and Pakistan and was commonly considered to be ancestors of modern elephants and sea cows. Geographically, this was a puzzling idea, because elephants and their relatives were groups that were known from Africa, not Asia. These new fossils indicate that anthracobunids are related to the tiny tapirs that are well known from the Pakistani rocks, and that perissodactyls probably originated in Asia.
