Brontotherium By Brady Brontotheriums
were known as the "Thunder Beasts." They roamed the western
half of North America during the last
ice age.
They mainly inhabited
such areas as California (Death Valley), Nevada, as well as
North and
South Dakota. Brontotheriums also lived in Asia. They lived
approximately 32 million years ago. Brontotheriums are commonly mistaken
with the modern day rhinoceros. Rhinoceroses have spikes on their
heads, Brontotheriums did not. But the two large animals are related to
each other. Scientists think
that the monstrous beasts became extinct because their environment
changed and no longer provided the food that they ate. They were not
"smart" enough to change their diet so they quickly left the
earth. They were used to eating plants but when the land dried, those
plants often died fast. "Thunder Beasts" were about 8 feet tall and 15 feet long. Males had larger tusk-like horns than the females.
