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 ...

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] Materials from the late-surviving A. africanum in Africa have suggested that A. africanum died out during the early Gelasian. [3]
Bear habitats are generally forests, though some species can be found in grassland and savana regions, and the polar bear lives in arctic and aquatic habitats. Most bears are 1.2–2 m (4–7 ft) long, plus a 3–20 cm (1–8 in) tail, though the polar bear is 2.2–2.44 m (7–8 ft) long, and some subspecies of brown bear can be up to 2.8 m (9 ...
