: This giant beaver specimen measures 11 x 7 x 5 inches (27.94 x 17.78 x 12.7 cm) and was found 8 feet below ground while a landowner was digging a pond near Russells Point, Logan County, Ohio, 1951. The giant beaver (Castoroides ohioensis) first became known to science from a specimen found while digging the Ohio Canal near Nashport, Ohio (northwest of Zanesville). Its scientific name reflects its similarity to the modern beaver (Castor canadensis) and the state where it was discovered. Castoroides was a massive rodent, and when mature, this extinct animal from the Pleistocene (Ice Age) was nearly as large as a modern black bear. Another prominent feature of the giant beaver was large incisors (front teeth), which could grow to be 2-3 times as large as the incisors of a modern North American beaver. View on Ohio Memory.
