Brontotherium, also called the Megacerops, is a giant hoofed mammal similar to a rhinoceros. It stands at nearly 8 feet tall!

Brontotherium means 'Thunder Beast.' The name certainly suits the gigantic armored herbivore!

Though it resembles a massive rhinoceros with two nose horns, Brontotherium is actually more closely related to horses!

The horns of males Brontotherium are larger than those of the female. This is because Brontotherium duel for their mates!
