: This partial skull of an adult Ice Age giant beaver measures 10.75 x 6 x 4.5 inches (28.4 x 16.3 x 11.0 cm) and was found seven feet below ground in a swampy area of Williams County, Ohio, that was being excavated for a farm pond. 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 Late Tertiary (3 million years before present) through the Pleistocene Era (10,000 years before present) was nearly as large as a modern black bear.
