The polar bear is the largest living species of bear and land carnivore, though some brown bear subspecies like the Kodiak bear can rival it in size. [ 31 ] [ 32 ] Males are generally 200–250 cm (6.6–8.2 ft) long with a weight of 300–800 kg (660–1,760 lb).
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 ...
Individual bears vary in size seasonally, weighing the least in spring due to lack of foraging during hibernation, and the most in late fall, after a period of hyperphagia to put on additional weight to prepare for hibernation. [38] [39] Brown bear skeleton. Brown bears generally weigh 80 to 600 kg (180 to 1,320 lb), with males outweighing ...
Polar bear feeding on a seal on an ice floe north of Svalbard, Norway. It is the most carnivorous species. The sloth bear is not as specialized as polar bears and the panda, has lost several front teeth usually seen in bears, and developed a long, suctioning tongue to feed on the ants, termites, and other burrowing insects
English: Three polar bears approach the starboard bow of the Los Angeles-class fast attack submarine USS Honolulu while surfaced 280 miles from the North Pole. Sighted by a lookout from the bridge (sail) of the submarine, the bears investigated the boat for almost 2 hours before leaving.
Arctotherium ("bear beast") is an extinct genus of the Pleistocene short-faced bears endemic to Central and South America. [1] Arctotherium migrated from North America to South America during the Great American Interchange, following the formation of the Isthmus of Panama during the late Pliocene.
Dog paw. The paw of the dog has a digitigrade orientation. The vertical columnar orientation of the proximal bones of the limbs, which articulate with distal foot structures that are arranged in quasi-vertical columnar orientation, is well-aligned to transmit loadings during weight-bearing contact of the skeleton with the ground.
Agriotherium is an extinct genus of bears whose fossils are found in Miocene through Pleistocene-aged strata of North America, Eurasia, and Africa.This long-lived genus persisted from at least ~11.6–2.5 Mya. [2]
