Giant Beaver (Castoroides ohioensis) Incisor   Save
Ohio History Connection
Description: This prehistoric giant beaver incisor (front tooth) was found while digging a drainage ditch in Clark County, some time prior to February 18, 1947. It is 8.75 inches (22.3 cm) long and 1 inch (2.5 cm) in diameter. The incisors of an Ice Age giant beaver 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 Era (Ice Age) was nearly as large as a modern black bear. View on Ohio Memory.
