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 inner bark, twigs, shoots, and leaves of such trees are also an important part of the beaver's diet. [59] The trees are cut down using their strong incisor teeth. Their front paws are used for digging and carrying and placing materials. The sound of running water dictates when and where a beaver builds its dam.
Dam construction begins in late summer or early fall, and they repair them whenever needed. Beavers can cut down trees up to 15 cm (5.9 in) wide in less than 50 minutes. Thicker trees, at 25 cm (9.8 in) wide or more, may not fall for hours. [56] When chewing down a tree, beavers switch between biting with the left and right side of the mouth.

The Eurasian beaver (Castor fiber) or European beaver is a species of beaver widespread across Eurasia, with a rapidly increasing population of at least 1.5 million in 2020. The Eurasian beaver was hunted to near-extinction for both its fur and castoreum , with only about 1,200 beavers in eight relict populations from France to Mongolia in the ...
The name likely comes from Native American or Colonial traditions.
Skull of a beaver. Castoridae is a family of rodents that contains the two living species of beavers and their fossil relatives. A formerly diverse group, only a single genus is extant today, Castor. Two other genera of "giant beavers", Castoroides and Trogontherium, became extinct in the Late Pleistocene.
Deer put on extra fat in the fall and grow a winter coat with long guard hairs for insulation. They also eat a high-fiber diet in the winter, which primarily consists of twigs and bark on trees ...
