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).
The shape of the claw differs between the bear species: black bear claws are strong and curved, which allows them to claw at tree bark; grizzly bear claws are long and straight, ideal for digging, and can be up to 15 cm (6 in) long; [59] [60] polar bear claws are thick and sharp for holding the slippery skins of seals.

This attack occurred about 24 kilometres away from the May 4, 2021, attack that killed David ...
Brown bear size, most often measured in body mass, is highly variable and is correlated to extent of food access. Therefore, bears whose range in areas with access to openings, cover, and moisture or water are on average larger, whereas those bears that range into enclosed forested areas or arid, sparsely vegetated regions, both of which tend to be suboptimal foraging habitat for brown bears ...
