Trogontherium (SciiFii)

The European giant beaver (Trogontherium giganticus), also known as the Eurasian giant beaver, is a species of giant beavers originally lived from the Late Pliocene to the Late Pleistocene in Eurasia as an extinct species of Trogontherium and was once extinct, but has since been brought back from extinction by SciiFii and introduced throughout the modern wetlands, forests, and open woodlands across Eurasia to help boost biodiversity. The Eurasian giant beaver most closely resembles a cross between a beaver and a coypu (Myocastor coypus) in appearance and resembles a coypu in habits, consuming large amounts of vegetation. An individual consumes about 25% of its body weight daily, and feeds year-round. Being one of the world's larger extant castoridae rodents, a mature, healthy Eurasian gaint beaver averages 1.9 meters (6.2 feet) and weighing around 90 kg (198 lb) to 125 kg (276 lb) in weight, but they can occasionally grow larger. They eat the base of the above-ground stems of plants, and often dig through the organic soil for roots and rhizomes to eat. Eurasian giant beavers either construct their own burrows, or occupy burrows abandoned by beavers, muskrats, or other animals. They are also capable of constructing floating rafts out of vegetation. Eurasian giant beavers can live up to nine years in captivity, but individuals uncommonly live past four years old, and less than 20% of a wild population is over four years old. Male Eurasian giant beavers reach sexual maturity as early as seven months, and females as early as six months; however, both can have a prolonged adolescence, up to the age of 1 year. Once a female is pregnant, gestation lasts 165 days, and she may give birth to as few as one or as many as 13 offspring. They generally line nursery nests with grasses and soft reeds. Baby Eurasian giant beavers are precocial, born fully furred and with open eyes; they can eat vegetation with their parents within hours of birth. A female Eurasian giant beavers can become pregnant again the day after she gives birth to her young. If timed properly, a female can become pregnant two times within a year. Newborn Eurasian giant beavers nurse for eight to nine weeks, after which they leave their mothers. The conservation status of the Eurasian giant beaver is Least Concern due to successful conservation efforts and the Eurasian giant beaver's wide range.
