How short-faced bear eat to sustain massive body size

1 Big front feet could attack giant mammals by pulling them to the ground.

1 Bones are very thin. They are too weak to attract and pull to the ground.

2 Long legs could run fast and catch some fast-running animals

2 fast-running animals could change directions and make sharp turns. However, bears are too heavy to slow down, so they could not catch these animals

3 Bears might be scavenger, and they might eat animals that are already dead

3 Scavengers have marks on their teeth, because dead animals have hard bones. The fact is we have not found any on the bears.
