The Etruscan bear was an Ursidae widespread in Europe in the lower Pleistocene, believed in the past to be the basis of the group of European and American brown bears. The specimens from the early Pleistocene were small in size and rather similar to the modern Tibetan bear, which weighs up to 200 kg. On the contrary, the specimens that lived at the end of the lower Pleistocene reached the size of a current brown bear. It was an opportunistic species, which colonized a great variety of environments, although it was probably adapted for woodland environments. In fact, its diet was omnivorous and included a variety of plants and animals, including fish. The Etruscan bear became extinct at the end of the lower Pleistocene, when it was replaced by the ancestors of the modern brown bear, coming from Asia.
