Castoroides (Latin: "beaver" (castor), "like" (oides) [2]), or the giant beaver, is an extinct genus of enormous, bear-sized beavers that lived in North America during the Pleistocene. Two species are currently recognized, C. dilophidus in the Southeastern United States and C. ohioensis in most of North America.
The earliest castorids belong to the genus Agnotocastor, known from the late Eocene and Oligocene of North America and Asia. [2] Other early castorids included genera such as Steneofiber , from the Oligocene and Miocene of Europe, the earliest member of the subfamily Castorinae, which contains castorids closely related to living beavers.
