Bears of the Pleistocene

[brotherbear]

According to a documentary about Arctodus simus, the theory was shot down about him running at race horse speed to catch fast moving prey. His long limbs are thought to be too gracile and would be too fragile considering his great bulk to make any sudden turns as would be needed while pursuing prey animals. In doing so the giant short-faced bear would likely break his own leg. 
Arctodus simus may have been a long distance walker following a keen nose from one carcass to another. His great size alone would have been enough to displace predators from their kills. Like the grizzly, he may have been a part-time hunter and just about a full-time scavenger. As a bear, he was an omnivore but his diet probably leaned more towards meat and less vegetation than a grizzly. 
Of course, this is all theory judged on fossil remains.  Reply
