According to an article, it seems the giant polar bear averages 1.2 tonnes.
I thought I remember reading this weight figure earlier but I forget the specifics. If you have follow up information to forward I would be interested to see it. This ties in with brotherbear's earlier question, in a way, since large modern brownies or polar bear can approach a tonne, then if we are talking about a very large form of early polar bear or brown/polar bear mix; I could see that bear weighing over a tonne.
No, the next longest ulna belongs to an Ursus maritimus specimen in the Zoological Institute of the University of Uppsala. Its total length is 428 mm, considerably less than the specimen you are referring to.

An interesting question, I'll have to try and find the answers.
Related to this: "One of the ulna's belonging to the Arctotherium angustidens specimen was intact-and 570 mm long. That bear was huge."
"... the largest Arctodus simus ulna yet found was 591 mm long."
See "THE LARGEST KNOWN BEAR, ARCTOTHERIUM ANGUSTIDENS, FROM THE EARLY PLEISTOCENE PAMPEAN REGION OF ARGENTINA: WITH A DISCUSSION OF SIZE AND DIET TRENDS IN BEARS", published in Journal of Paleontology, 85(1), 2011, p. 69–75.

What is the source of your Camera20130123182659.jpg? I would like the read the rest of the article.
The explanation for Table 4 may be a bit confusing. Only the first specimen is from Langebaanweg. Ursus arctos (CFM 63802) is from Mother Goose Lake, Alaska, USA. It is a coastal brown bear (Ursus arctos gyas).
