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 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 ...
By far the largest bear species discovered, estimated to stand around 4.0 m (13 ft) and weighing 1,600 kg (3,500 lb), they are genetically closer to the spectacled bear (Tremarctos ornatus), than to Arctodus of North America, implying the two extinct forms evolved large size in a convergent manner.

Price first spotted the bear in 2018, and said it was “smaller then and has almost doubled in size since originally spotted.” “At that point he was already walking around by himself and was ...
The average skull size of Kodiak bears that were killed by hunters in the first five years of the 21st century was 63.8 cm (25.1 in) for boars, and 55.4 cm (21.8 in) for sows. [ 18 ] Also, an individual named Teddy, which portrayed a killer bear in the movie Grizzly , stood 3.4 metres (11 ft) tall on its hind legs and was the largest bear in ...
Arctodus is an extinct genus of short-faced bear that inhabited North America during the Pleistocene (~2.5 Mya until 12,800 years ago). There are two recognized species: the lesser short-faced bear (Arctodus pristinus) and the giant short-faced bear (Arctodus simus).
Original - The polar bear (Ursus maritimus) is a bear native to the Arctic. Polar bears are the world's largest land carnivores, with most adult males weighing 300–600 kg (660–1320 lb); the adult female (pictured) are about half the size of males. A semi-aquatic marine mammal, the polar bear has adapted for life on a combination of land ...
