Largest living perissodactyl (odd-toed ungulate)

The world's largest living perissodactyl (odd-toed ungulate) is the southern white rhinoceros Ceratotherium simum simum. Mostly confined to southern Africa, and with South Africa as its stronghold, it can attain a length of 4.2 m, a shoulder height of 1.85 m, and a weight of 3.6 tonnes. Present-day odd-toed ungulates (hoofed mammals) consist of the rhinoceroses, equids (horses, zebras and asses), and tapirs, but in prehistoric times there were several additional groups, including the bizarre claw-footed chalicotheres, and the enormous titanotheres or thunder beasts.

The largest land mammal ever known to exist was also a rhinoceros, known variously as Paraceratherium, Baluchitherium and Indricotherium, which was hornless and greatly resembled animmense giraffe, due to possessing very long legs and neck. It existed across western Asia and Europe around 35 million years ago. A restoration in the American Museum of Natural History in New York City, USA, measures 5.41 m to the top of the shoulder hump and 11.27 m in total length. The most likely maximum weight of this browser was revised in 1993 to 11–20 tonnes from earlier estimates of 34 tonnes.
