Basic Giant Beaver Info
There were two known species of giant
beaver: Castoroides ohioensis and Castoroides
leiseyorum. While leiseyorum has only been found in Florida,
ohioensis roamed much of North America. With a length of nearly ten
feet and a weight of about 250 lbs, the giant beaver was one of the largest
rodents to live (few rodents were larger).
The giant
beaver would have had a narrower tail and thicker incisors than its modern day
relative and may have been less aquatic. There is no clear evidence
pointing toward giant beaver lodges.
There are
several Native American stories about giant beavers, however, it is not clear
whether these stories relate to Castoroides or not.
