Species: Arctodus simus - short-faced bear
Body weight for Arctodus simus: Much variation in body mass estimates in literature (due in part to extreme sexual dimorphism in these bears and lack of large numbers of Arctodus to measure); new estimates of 388 kg (855 lb) (female?) to around 1,000 kg (2,205 lb) (male?)
Shoulder height for A. simus: 1.6 m (5.25 ft)
Tail length: vestigial
|Distribution & Status||Behavior & Ecology|
Status: Extinct by 10,000 years ago
Locomotion: Pacing gait with long legs; feet face forwards so doesn't waddle or walk "pigeon-toed" like other bears.
Social Groups: presumed solitary except female with cubs
Diet: As an adaptable omnivore, ate plants, scavenged carcasses and may have killed prey too.
Predators: none known on this giant bear
|Reproduction & Development||Species Highlights|
Birthing: Females occupied dens
|Feature Facts: Arctodus is variously described as a hyper carnivore, a specialized scavenger, and an omnivore. A new comprehensive, comparative study of 411 individuals of 57 species of living bears, dogs, cats and hyaenas and fossil Arctodus (Figueirido et al 2010) favors an omnivorous lifestyle, similar to that of Alaskan Brown Bears today.|
