He combined the rhinos with the Glires, a group now consisting of the lagomorphs and rodents. Mathurin Jacques Brisson (1723–1806) first separated the tapirs and hippos in 1762 with the introduction of the concept le tapir. He also separated the rhinos from the rodents, but did not combine the three families now known as the odd-toed ungulates.
Brontotheriidae is a family of extinct mammals belonging to the order Perissodactyla, the order that includes horses, rhinoceroses, and tapirs.Superficially, they looked rather like rhinos with some developing bony nose horns, and were some of the earliest mammals to have evolved large body sizes of several tonnes.
Perissodactyls range in size from the 1.8 m (6 ft) long Baird's tapir to the 4 m (13 ft) long white rhinoceros. Over 50 million domesticated donkeys and 58 million horses are used in farming worldwide, while four species of perissodactyl have potentially fewer than 200 members remaining.

However, the existence of the kabomani tapir as a distinct species has been widely disputed, and recent genetic evidence further suggests that it ...
