Short-faced bear : ウィキペディア英語版 | Short-faced bear
The short-faced bear (''Arctodus spp.'') is an extinct bear that inhabited North America during the Pleistocene epoch from about 1.8 Mya until 11,000 years ago. It was the most common early North American bear and was most abundant in California. There are two recognized species: ''Arctodus pristinus'' and ''Arctodus simus'', with the latter considered one of the largest known terrestrial mammalian carnivores. ==Naming and etymology== The name short-faced bear derives from the shape of their skulls, which appear to have a proportionally short snout compared to other bears; this characteristic is also shared by its extant relative the spectacled bear. However, this apparent shortness is an optical illusion caused by their deep snouts and short nasal regions. The scientific name of the genus, ''Arctodus'', derives from the Greek language and means "bear tooth".
