Chilotherium

Chilotherium

 

a genus of extinct mammals of the family Rhinocerotidae, widespread during the Neogene. Members of the genus Chilotherium were typical representatives of hipparion fauna. They were about 3 m long and stood about 1.5 m high. The body was massive, and the legs were short. The cranium was short. The anterior part of the lower jaw was very wide and had two incisors in the form of small tusks. Horns were absent. The animal inhabited river valleys and lake shores, feeding on plants that it dug out of the soft ground with its incisors. There were about ten species. Remains of Chilotherium have been found in various sites of hipparion fauna in Eurasia; in the USSR remains have been found in Moldavia, the Ukraine, Kazakhstan, and Middle Asia.
