~Yes, Allosaurus had a good sized head, but it was not proportionately large compared to the body like it is in, say, Giganotosaurus. Its not its size that makes it dangerous, but rather the way in which it functions.

~Allosaurus did not have better eyesight than the bear. Still bearing eyes on the sides of its head (and the crests on its face don't help either), it may have even had a bit of a blind spot directly in front of it, and had very poor depth perception, if any at all. Many mammalian predators, on the other had, have developed eyes that face forward, thus giving them superior vision.

~Allosaurus may have actually been able to beat the bear in a race, though of course speed is something hard to gage on extinct animals.

~The polar bear does not have more useable arms than Allosaurus. They are probably stronger, sure, but usability is something else. Bears and carnosaurs both have different functionality and mechanics of the arms, and Allosaurus actually had very large claws on its hands. The arms on either predator would have been formidable weapons.

I meant, in comparison to the bear, the head is bigger. And, I believe the theory that Allosaurus used its mouth like a "hatchet" to slash at prey, as it's jaws were not extremely powerful like Tyrannosaurus ect.

Ok, fault on my behalf, was basing the eyesight thing on Tyrannosaurus. And I think this bear was supposed to be mostly vegetarian, so I also based eyesight on that. But then again, brain could make a difference to eyesight, and the bear certainly has more of that.

I really think that a bear would be faster. Something like Gallimimus could, perhaps, be faster than the bear.

If I remember correctly, the arms of Allosaurus were used for "hanging on", and didn't have the same shoulder joint as Deinonychus and kin, which could both "hang on" AND swivel round it a completely circular motion to slash at prey. A bears forelegs are much bulkier than any Allosaurus's, and, in my opinion, would be much more useful in this situation, where the bear is smaller than the allosaurus when on all fours.
