All the biggest skulls are Brown Bear skulls...also significantly heavier and deeper.
The record score for a Polar is 28.5 but 31 for Brown, however the Brown bear skull is much deeper, creating a significantly heavier skull at maximum sizes.

Then close to 2003 it became aggressive toward it and was removed.The pic comparsion with the 2 standing Polar Bear and Brown Bear is also grossly unfair for any comparsion.You can tell by looking at the paw and skull size that the Brown Bear is a quite pitiful specimen. I would doubt its set up for correct comparsion but merely an accident for such because the 2 animals just happen to be in same frame......but even here....with such gross disparity, you can see that the Brown Bear is not outgunned in the build of the shoulder ........quite astonishing given the disparity.The anology of Polar Bear skulls having slightly weaker bites but larger Polar Bears then assuming to have more powerful jaws is also incorrect.For starters Polars do not have larger skulls, with all the biggest record book skulls belonging to Brown Bears, while deeper research into bite pressures realizes 17 to 20 % more power of bite at similar size.This however (as pointed out by Jim Carmichael and highly important) inspite of their teeth being much blunter, with the canines being more conical instead of needle point and Molars compared to carnasial slicing teeth. Thus.....much bigger area of surface contact but still greater bite force of 17 %If you add 17 % to larger potential skull and greater cross sectional area of bite.........Brown Bear have much more powerful jaws.Next Height and girth comparsions.No Polar Bear will ever be 12 metres tall which is well over 12ft. This is eroneous information often found with 60s research. The largest ever Polar Bear of 2200lbs is actually mounted and stands 11.2ft, slightly shorter than the 11.4ft Goliath Brown Bear!As regard Girths.....the greatest known girths have been measured on the Alaskan peninsula and these for Brown Bear. Several of the animals hit 200cm girths and in rare cases considerably more.It is generally agreed that at similar weights, the Brown Bear is a stouter , more robust animal but a much less great tendancy to carrying hip fat when compared to the Polar Bear......and thus.....reduced weight when compared at maximums.My research extends back well over 25 years....and despite Bolds best efforts at staying stuck on error...i really do know what i am talking about..... but i am now tired of defending this Bears assets against the constant onslaught from Brown Bear negative types and the time has come to let go and return to the old site.
