Ursus Maritimus Tyrannus was a very large fossil subspecies of polar bear, descended from an Arctic population of brown bears. Its name in Latin means Tyrant sea bear. Ranging up to an estimated mass of 1,200 kg (2,600 lb), it was rather larger than any living bear race and was one of the largest mammalian terrestrial carnivores ever to exist, next to the South American short-faced bear. The species is mentioned by Björn Kurtén, who assigned it to a polar bear subspecies, U. m. tyrannus. Its bones have been found in England.
