It's sort of a crappy documentary but boys, Arctodus simus does have one of (if not) the most impressive Bear skull ever (at 21:51), maybe even one of the most impressive Carnivorans skull ever.

Great documentary Verdugo. “This animal was built for power and intimidation” yeah that was some skull, those carnassials were able to crack bones.

I'm guessing the jaw structure has never been compared with that of modern day Hyenas. Think of the jaw of a Hyena but on a larger scale. Bite force must have been off the charts.

The arctodus simus has arguably the strongest jaws among bears despite the being not as heavily built as other bears. Impressive video and picture.

Here we have a spotted Hyena skull below right and a Giant short faced Bear skull below left. Aside from the back teeth being slightly different, both seem to have a broad shorter snout. We're well aware of the vice like jaw and bite force of the Hyena, the short faced Bears jaw length would seem similar in relation to the size of the entire head. Both animals had a relatively short snout and I can't help but wonder if this contributes to higher bite force than other predators with a longer jaw length? Would this also lend itself to the theory that like the Hyena the Short faced Bear could have possibly been predominantly a scavenger? Food for thought

Well i dont know about the snout, (maybe Verdugo can shed some light better), but it has pretty much been established that the short faced bear was mostly a scavenger and a Kleptoparasite. And this is because he had long slender legs that prevented him from catching prey animals. He would had trouble making turns.

Also, very important, at around minute 14, it is stated that when the ice age started, the Saber toothed tiger (Smilodon), among other animals, did not adapt and died out. But some species of bears, like the Panda, adapted and survived. “Only the toughest and most adaptable survive”. Bears are more adaptable than felids.

Map showing locations of reported Arctodus simus localities with arrow pointing to the Florida sites. Some points represent multiple localities and/or specimens. See Methods section for details about plotting the points.

Arctodus simus lifestyle: Killing an adult bison ( questionable ) - Scavenging a dead horse - Feeding on berries.

His distant cousin, Arctotherium has the nick-name hyena bear. Their bite-force of the short-faced bears were monstrous; far greater than that of a grizzly - even at size-parity - and never was a grizzly at size-parity with these giants. Arctodus simus ( tallest of all bears ). Arctotherium angustidens ( heaviest of all bears ).

I think a shortface bear would have no problem in taking down a bison. Even the largest of bison. The only true rival to the shortface bear would be the american lion.

Maybe so, but this bear was not a hunter. However, he could displace any true predator from a bison carcass. The big cats likely avoided the monster, giving him no trouble. However, life for she-bears and juveniles was probably quite hazardous. ( IMO ).

Agree no big cat would dare approach a shortface bear except for she bears and juveniles as you mentioned above. This bear was just too bear for such attacks.

Reply #131 - Above picture: Either a smaller A. simus or some over-sized cats. Perhaps depicted a short-faced she-bear.
