So you think you already know which area produces produces the largest polar bears?

Approaching 600 kg, the Foxe Basin cohort are the largest specimens I have come across.

"When fully grown, adult male polar bears in Canada range in weight from 450-550 kg and most adult females weigh between 160-270 kg."
Stirling, Ian, Wendy Calvert, and Dennis Andriashek. 1980. Population ecology studies of the polar bear in the area of southeastern Baffin Island. [Ottawa]: Canadian Wildlife Service.

Are there any recent polar bears at or over 600KG? I haven't gone after polar bear technical reports the way I have for grizzly bears. If mature male polar bears are averaging 500 kg or so I think it's safe to say there are 600 + kg specimens in the mix: " Size and Weight. The polar bear is the largest of the extant bears (DeMaster and Stirling 1981). In Hudson Bay, the mean scale weight of 94 males >5 years of age was 489 kg. The largest bear in that group was a 13-year-old, which weighed 654 kg (Kolenosky et al. 1992). The heaviest bear we have weighed in Alaska was 610 kg, and several animals were heavy enough that we could not raise them with our helicopter or weighing tripod. Some animals too heavy to lift have been estimated to weigh 800 kg (DeMaster and Stirling 1981)." Armstrup, C. Steven. 2003. Polar Bears (Chapter 27) in Wild Mammals of North America. PDF LINK: www.polarbearsinternational.org/sites/default/files/pdf/PolarBearsComprehensive.pdf"Adult males typically measure 200 – 250 cm in length from the tip of the nose to the tip of the tail and weigh 400 – 600 kg, although some individuals may reach about 800 kg." Stirling, Ian. Polar Bear (Ursus Maritimus) in Encyclopedia of Marine Mammals, 2002.

The largest polar bear ever recorded was shot in Kotzebue Sound, Alaska in 1960 weighing a grizzly 1002 kilograms or 2,210 pounds and stood 11 feet 11 1 1/2 inches in height.

11 feet 11 inches = 3.6322 meters
Hello, are you sure that this bear is 3,63 meters in height? Where did you get this value?
Because on a blog we can read:
Does ursus maritimus tyrannus (probably a brown bear ursus arctos) was bigger and taller than the top one?
Thanks.

On the world record polar bear specimen, there was a typo error on my part (thanks for the catch - a correction has been made). Your quote by Wood (1981) is accurate and repeated again in the 1983 Guinness Book of World Records: www.washingtonpost.com/wp-dyn/content/gallery/2010/04/30/GA2010043002072.htmlRE: U.m.tyrannus, the fossil data on this bear which some have argued was a large brown bear is very limited. Now there is speculation explaining Irish polar bear ancestry (as they mated with brown bears).

Ok, thanks for the photos, but i would like to compare measurements of large kodiak bears ulna and UMT's ulna, do you have measurements about large kodiak bears ulna?
But you don't know if UMT is bigger than the giant polar bear on the picture?

But you don't know if UMT is bigger than the giant polar bear on the picture? If you want comprehensive extant bear skeletal/fossil information my suggestion is to explore/examine museum data collections. RE: Kodiak bears, Bart the Bear weighed around 1,500 lbs and stood 9 1/2 feet tall: RE: U.m.tyrranus plus complimentary extant ursid fossil data, visit the following link and go to page 185: books.google.com/books?id=kzWQM4aRNeoC&pg=PA178&dq=bjorn+kurten+the+evolution+of+the+polar+bear&hl=en&ei=Y5mLTsHjJsfn0QGppbnxBA&sa=X&oi=book_result&ct=result&resnum=2&ved=0CDEQ6AEwAQ#v=onepage&q&f=falseLink source: Originally published in 1964, Bjorn Kurten: The evolution of the Polar Bear, Ursus maritimus Phipps. 30 pp; reprinted in On evolution and fossil mammals (1988). I think the fossil data (a single incomplete ulna fossil) is too limited to give any accurate scale for U.m.tyrannus size. RE: the record polar bear, as far as I know all we have in so far as data is the Wood (1981) information.
