Kid Decode: Fossil names can shuffle around like museum chairs.
4. It Was a Brontothere
Brontotheres were extinct odd-toed hoofed mammals related to the broad group that includes horses, rhinos, and tapirs.

Brontotheres were herbivores, probably browsing on leaves and soft plant foods in Eocene habitats.
Kid Decode: The thunder beast powered itself with plants, not prey.
7. It Lived in North America
Brontotherium-style fossils are associated with Late Eocene North American deposits.
Kid Decode: Ancient North America had forests, plains, and very large horned browsers.

Big brontotheres such as Megacerops were among the largest land mammals of their time in North America.
Kid Decode: Imagine a rhino-shaped tank browsing quietly through the Eocene.
9. Baby Brontotheriums Were Young
Baby Brontotheriums can be called young or calves, though scientists do not use a special baby name for them.
Kid Decode: A small calf-like young would have had a lot of growing into thunder to do.
10. Brontotheres Went Extinct at the End of the Eocene
Large brontotheres disappeared near the end of the Eocene as climates cooled and habitats changed.
Kid Decode: The thunder beasts rumbled out before the Oligocene fully took over.
The Weirdest Brontotherium Fact
Brontotherium is one of those prehistoric names kids love, but scientists often use Megacerops for many of the same famous thunder beast fossils.
