Massive Mammal

It's amazing how much bigger mammals were 14 million years ago, when human society was but a far off twinkle in the universe's eye. Meet the Indricotherium, a monster from the Miocene period. At 25 ft. tall and 26 ft. long, this ancestor of the rhinoceros was the largest land mammal in history.

Once these guys roamed the temperate forests of Asia, eating leaves like crazy to support their 10-20 ton frame.

It is named after the mythical Russian Indrik, a fantastical beast that lives on a magical mountain and is king of all the animals. Good that an herbivore got a shot at that job once, I say.
