Indricothere

Indricothere (Paraceratherium transouralicum) was a huge herbivore. Their closest living relatives are the rhinos. They look like huge slim hippos. Indricothere means "indrik beast" an indrik is a mythical Russian beast with a single horn, a bit like a unicorn. Indricotheres don't have horns, though. And, they were land mammals.

They ate upper branches in trees. They were so huge. Large males were 7 metres. They weighed 15 tons, and the females weighed 12 tons. Indricotheres lived in the Oligocene period with the hyaenodon. They didn't have that many enemies, since they were so big.
