Some scientists think the Mountain Beaver is the world's most primitive living rodent, similar in appearance and behavior to animals that lived 60 million years ago.

A bold, solitary stalker of small game, the bobcat's diet consists mainly of mice and rabbits, but it has been known to kill muskrats, mountain beavers, foxes and weasels.

This group includes squirrels of many kinds, Old World dormice, and a strange species called mountain beavers.

The living rodent with the most archaic characters, most like the common ancestor of the Rodentia, is the sewellel or mountain beaver (which is not a true beaver at all) of the northwestern United States.
