Population statistics

Brontotherium (bronto=thunder, therium=beast) was an ancient mammal. Evolutionists believe it lived during the Eocene and during parts of the Oligocene Epochs, with these being part of the Cenozoic Era. It is one of the more well-known and rather sizeable mammals from the Tertiary Period.[1]


Named after the thunderous footsteps it was thought to produce, the Brontotherium was a large herbivore, totaling at sixteen feet long and eight feet tall. These ten thousand pound quadrupeds may have looked fierce, but they fed mostly on vegetation. They possessed huge, colossal skulls and a powerful, bulky frame.[2]


Brontotherium have a gigantic, Y-shaped horn protruding from their heads. The horn is thought to be made of bone. Probably not used for fighting, the horn was most-likely used for attracting a mate.[3]


Brontotherium lived in scrublands and forests. It is thought that Brontotherium went extinct because its habitat transformed into grasslands to which it could not adapt.[4]


These mammals fed on low-growing shrubs and vegetation. The Brontotherium possessed huge, flat teeth which were used for crushing up vegetation. This helped it in the digestion process.[5]

Evolutionary claims

Evolutionary scientists say that Brontotherium was related to modern rhinoceroses due to the fact that it possesses a nose horn. Both are very bulky creatures, the Brontotherium far surpassing the rhinoceros.[6]
