Castoroides ohioensis, or Giant Beaver, is an extinct species of enormous beavers that lived in North America during the Pleistocene. C. leiseyorum and its northern sister species, Castoroides ohioensis were the largest beavers to ever exist. Prehistoric giant beavers were much larger than modern beavers. Their average length was approximately 1.9 m (6.2 ft), and they could grow as large as 2.2 m (7.2 ft). The weight of the giant beaver could vary from 90 kg (198 lb) to 125 kg (276 lb). This makes it the largest known rodent in North America during the Pleistocene and the largest known beaver.
