: This giant beaver skull measures 8 x 6.5 x 3.5 inches (20.32 x 16.51 x 8.89 cm) and was discovered in buried peat at housing development near Northern Lights Shopping Center (Franklin County) in 1957. It is carbon dated at 11,480 years before present (plus or minus 160 years). This specimen clearly shows the animal's large incisors, which could grow to be 2-3 times as large as the incisors of a modern North American beaver. 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. When mature, this extinct animal from the Pleistocene (Ice Age) was nearly as large as a modern black bear. View on Ohio Memory.
