The Castoroides or The Giant Beaver is a prehistoric beaver, When the giant beaver roamed over North America, other animals steered clear. As big as a bear, this plant eater had buck teeth like its modern cousins, though they were long and curved, and they made nasty weapons. The giant beaver didn't build dams and underwater dens with secret entrances because it didn't need to hide from predators. Few could tackle its bulky body or avoid the beaver's bite. They are found in North America They Lived in The Ice Age, They Are Borned in 1838
Castoroides species were much larger than modern beavers. Their average length was approximately 1.9 m (6.2 ft), and they could grow as large as 2.2 m (7.2 ft). The weight of the giant beaver could vary from 90 kg (198 lb) to 125 kg (276 lb). This makes it the largest known rodent in North America during the Pleistocene and the largest known beaver.[3] Recent analyses suggest that they weighed less, closer to 77 kg (170 lb), but this is disputable.
The hind feet of the giant beaver were much larger than in modern beavers, while the hind legs were shorter. The tail was longer and may not have been paddle-shaped as in modern beavers. It can only be assumed that its feet were webbed as in modern species. The skull structure of the giant beaver suggests that it participated in extended underwater activity, thanks to the ability to take more oxygen into its lungs.
One of the defining characteristics of the giant beaver was their incisor teeth, which differed in size and shape from those of modern beavers. Modern beavers have incisors with smooth enamel, while the teeth of the giant beaver had a striated, textured enamel surface. Their teeth were also much larger, up to 15 cm (6 in) long.
