Polar bear. The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed. The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb). The species is sexually dimorphic, as ...
Ursus (mammal) Ursus. (mammal) Ursus is a genus in the family Ursidae (bears) that includes the widely distributed brown bear, [3] the polar bear, [4] the American black bear, and the Asian black bear. The name is derived from the Latin ursus, meaning bear. [5][6]
List of ursids. Brown bear (Ursus arctos) Ursidae is a family of mammals in the order Carnivora, which includes the giant panda, brown bear, and polar bear, and many other extant or extinct mammals. A member of this family is called a bear or an ursid. They are widespread across the Americas and Eurasia. Bear habitats are generally forests ...
This genus is probably the direct ancestor to the North American short-faced bears (genus Arctodus), the South American short-faced bears (Arctotherium), and the spectacled bears, Tremarctos, represented by both an extinct North American species (T. floridanus), and the lone surviving representative of the Tremarctinae, the South American ...
The brown bear (Ursus arctos) is a large bear native to Eurasia and North America. It is one of the largest land carnivorans, rivaled in size only by its closest relative, the polar bear, which is much less variable in size and slightly bigger on average. The brown bear is a sexually dimorphic species, as adult males are larger and more ...
Genus: Ursus. Species: U. maritimus × U. arctos. Polar/brown bear hybrid taxidermy specimen on display at Natural History Museum at Tring in Hertfordshire, England. A grizzly-polar-bear-hybrid (also named grolar bear, pizzly bear, zebra bear, [1][2] grizzlar, or nanulak) is a rare ursid hybrid that has occurred both in captivity and in the wild.
The ulna is estimated to have been 48.5 cm (19 in) long when complete- for comparison, modern subadult polar bear ulnae are 36–43 cm (14–17 in) long. [1] The ulna was dated to the early Weichselian of the Late Pleistocene (~70kya). [2] Of the 16 specimens identified as Pleistocene polar bears, this is the only fossil ascribed to this ...
Nanuqsaurus. Nanuqsaurus (meaning "polar bear lizard") is a genus of tyrannosaurine theropod dinosaur known from the Late Cretaceous period (middle Maastrichtian age) Prince Creek Formation of the North Slope of Alaska, having lived roughly 70-68 million years ago. It contains a single species, Nanuqsaurus hoglundi, known only from a partial ...
