The first rhino ancestors appeared on Earth during an epoch known as the Eocene, along with a number of other mammal species. Earth’s climate at the start of the Eocene was very warm, with temperatures at the poles and the equator not being significantly different, and little or no ice to be found. By the end of the epoch, however, ice sheets and glaciers had returned.
