theundertaker45: I see bro, you are right. That must be a monster Ingressus specimen.

King Kodiak Yes, they are much longer but remember that those belong to short-faced bears with extremely long forelimbs. If you'd compare a cave bear and a short-faced bear of similar weight, the short-faced bear will definitely have the longer limbs. The largest cave bear humerus that Christiansen and Harris included in their sample measured ~459mm and procuded weight estimations of up to 774kg. If I apply isometric scaling to the Ingressus bone based on the Spelaeus weight estimation, it may have ranged up to 1043kg which would put it in the league of 1000kg+ bears. If this hold true: Result of your conversion:1043 kilograms is equal to 2,299.42 pounds (avoirdupois). This would make Ursus ( spelaeus ) ingressus the "king of bears".

Well not just yet brobear, remember we have an Angustidens specimen estimated at 1111 kg (2449 lbs), and a Simus specimen estimated at 1256 kg (2769 lbs).

Rounded off ( as these are estimations ): Ingressus: 2,300 lbs / Angustidens: 2,450 lbs / Simus: 2,750 lbs. You're right Kodiak; we can't beat those giant short-faced bears.

What we can say now, is that Ingressus has joined the realm of the largest species, right up there with the short faced bears.

I hope that more material on Ingressus will be discovered; I mean we have material of females exceeding male Spelaeus males kn size, that's astonishing. We have the largest bear skull of all time. So for now I have made my choice on who to consider the "King of all Bears".

The short faced bears might had longer humerus, but of course, based on the study that Undertaker posted, we know the second largest cave bear, Spelaeus, had more humerus stoutness than Simus:
1. Cave Bear (Ursus Spelaeus) - 34.4%
6. Arctodus Simus - 31.8%

i thought this thread was for prehistoric bear size, but i guess not. i'll post it in the Steppe brown bear thread.

Not a problem. I'm very interested on how the Steppe bear measures up to the biggest cave bears.

Here we have 2 skeletons of male cave bears standing up. The first is 280cm tall and the second is 260cm tall according to the authors. Actually, i have never seen a cave bear skeleton reaching 3 meters high. So 1,69m at the shoulder is far too big dear brobear. How do you calculate the value of 1,69m at the shoulder? A shoulder height of 1,3 or 1,4 meter is more realistic and it's already very impressive. Keep in mind that the largest cats were about 1,2 meter at the shoulder and less robust than the cave bear. They were quite impressive though with only 1,2 meter for large prehistoric lions. Anyway, these bears are very big, at least 500kg or a bit more if they are well fed.

The largest cave bear species (Ursus spelaeus and Ursus ingressus) were bigger and heavier than today's Kodiak bear which averages for a fully grown male (9 years+) - 1077.3 pounds with a record size of 1600+ pounds.

I tend to agree with you on that point. But what we have? 1. Cave bears (Ursus ingressus) have proven to have larger skulls than Kodiak bears, it is a fact. 2. The real problem is that we lack data about humeral (or femoral) measurements concerning large kodiak bears so it is difficult to really compare them. 3. They have not the same proportions. The back of Kodiak bears is very high (see Bart the bear 2), whereas the back of cave bears was very low (see your profile picture, i have this figurine ). Your image presents a kodiak bear which is 133cm at the shoulder. I suspect that some kodiak bears are a bit taller at the shoulder (see Bart the bear 1 and 2). Anyway, a cave bear which is 145cm at the shoulder is enormous, but i would like to know how " 145cm" has been calculated.
