Although true beavers never had horns on their heads, fossils have shown that beavers did exist around the time the Ice Age films take place. However there is a significant difference between the beavers in the films and the beavers that lived during the ice age.
Horned gophers are the smallest known horned mammals and the only known rodents ever to have had horns. They are also one of only two known horned fossorial mammals, the other being Peltephilus, an extinct species of armadillo. They were native to what is now the Great Plains of North America, most concentrated in Nebraska.
Our relationship with North America’s largest rodent is so complex that we can no longer classify beavers as simply as Horace T. Martin did in Castorologia, an 1892 zoological monograph written when beavers hovered on the brink of extinction.
But this giant species became extinct with the end of the Ice Age while its smaller cousin was able to live on to this day. And now scientists know why: This giant beaver simply didn’t chuck wood like its smaller counterpart.
Was there a prehistoric beaver?
The oldest giant beaver fossils (of Castoroides leiseyorum from Florida, U.S.A.) are 1.4 million years old. In Canada, fossils of Castoroides ohioensis—probably from the last interglacial age (about 130 000 years ago)—were found in Toronto, Ontario, and in the Old Crow Basin of Yukon.

What did beavers evolve?
However, some scientists believe the giant beaver evolved from an ancient beaver called Dipoides, which is known to have been a wood cutter. Comparison with fossils of both Dipoides and the modern beaver suggest that the giant beaver was semi-aquatic and may have been a dam-builder with a tendency to cut wood.
When did the giant beaver go extinct?

How did the giant beaver go extinct?
