I did a lot of calculations taking excellent data on the ShaggyGods-Forum into account; here is a summary of Alaska Peninsula brown bear skull data:
Alaska Peninsula Brown Bear (per Miller & Sellers, 1992)
Greatest Skull Length: 425.56mm for males (n=16) Zygomatic Width: 241.12mm for males (n=16) Greatest Skull Length/Zygomatic Width-Ratio: ~1.765 for males
Alaska Peninsula Brown Bear (per Glenn, 1980)
Greatest Skull Length: 420.54mm for males (n=44); 384.97mm for females (n=134) Zygomatic Width: 258.82mm for males (n=44); 225.4mm for females (n=134) Greatest Skull Length/Zygomatic Width-Ratio: ~1.625 for males; ~1.708 for females

Reply #209: I am surprised to read the skull measurements of the Himalayan brown bear which ( according to the scant information we have ) should be perhaps the smallest of all living brown bears.

prehistoricict.blogspot.com/2011/11/strongest-terrestrial-mammal-bite-ever.html SATURDAY, 5 NOVEMBER 2011 - The Strongest Terrestrial Mammal Bite Ever. Wroe suggests that Agriotherium had a far stronger skull and bite force, as it fed upon a wider variety of prey to get at the nutritious red meat. In contrast, the polar bear possessed the weakest bite force and skull strength out of all of the specimens. Wroe believes that this contrast is because Agriotherium was adapted to feed upon meat, whereas the polar bear has a diet of soft blubbery seals, eating the energy-rich fat as opposed to the tough muscle.

The polar bear still has the best slicing bite which can cut through thick hide of beluga whales and walruses.

The greatest average skull length for cheetahs should be around 163-203mm according to paleontologist Abinav pradhan

Agriotherium africanum: Skull measures 20" long, 12" wide, 15" high - How does this compare with Arctodus simus? Arctodus simus: 521 millimeters is equal to 20.51 inches long. Not so much difference.

I would love to see a comparison of Ursus ingressus and Arctodus simus. ( I suppose that Ursus arctos priscus - the Steppe bear would be roughly the size of Ursus ingressus ). Anything on the skull of the Steppe bear?

Anything on the skull of the Steppe bear? Yeah, here is a chart i had found, they have less length than the record prehistoric bears that we have:

No scores given because they only gave the length of the skulls, not the width. But the longest one was 477 mm, far away from the prehistoric record bears.

477 millimeters is equal to 18.78 inches. This gives me the impression that the "huge" Pleistocene brown bears of Europe are just hype. This is the size of a large Kodiak or polar bear living today.

Anyhow, only 5 specimens were in that chart, so its a very small sample. There might be larger Pleistocene European brown bear skulls.

Or perhaps some massive bones with skulls missing or in bad condition.
