Palaeocastor (SciiFii)

The burrowing beaver (Palaeocastor americanum) is a species of beaver that originally lived in the North American Badlands during the late Oligocene period to early Miocene as an extinct species of Palaeocastor and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern open woodlands, grasslands, shrublands, scrublands, and badlands across North America to help boost biodiversity. The burrowing beaver is much smaller than most beavers, growing to be about the size of the black-tailed prairie dog (Cynomys ludovicianus). Unlike most beavers, the burrowing beaver, as its name suggests, is predominantly a burrowing animal instead of an aquatic animal. The burrowing beaver lives in family groups like other beavers and employes a K reproductive strategy instead of the normal r-strategy of most rodents. This is where the parent animals actually invest a greater amount of time and effort into just razing a small number of young which will accompany their parents until they are almost fully grown.‭ The burrowing beaver is a herbivorous animal that primarily feeds on various grasses, seeds, roots, tubers, bulbs, and crops. The burrowing beaver is known to make uniquely-shaped burrows known as "Devil's corkscrews", which are often tree-sized, screw-like underground formation. The basic form of the burrow is an elongated spiral of hardened earth material that inserts into the soil as deep as 3 metres (9.8 ft). The burrowing beavers excavate their burrows with their incisors, not their claws. The burrowing beavers make these burrows to maintain a more consistent temperature and humidity level. The conservation status of the burrowing beaver is Least Concern due to successful conservation efforts, the burrowing beaver's wide range and its tolerance to many of the human activities.
