Bears of the Pleistocene

About #206: very impressive skeleton (the first one especially) ! But, by seeing the skull we don' t realize it's a "short faced" bear. When I compare with other bears' skulls the difference doesn't seem to be blatant. 

However at the #196, we really see that it's a short faced bear ! That's astonishing. Reply

Short-faced bear skulls are normally shorter from front-to-back, with the same dimensions in other areas of the skull as other bears. Reply

Incredible the size of the largest Cave Bear Skull it is huge, I did not expect such a huge skull I expected that the largest ones were a little over 50 cm long. Reply

Also, this species of Cave bear (Ursus ingressus) was more carnivorous and aggressive than the previous one (Ursus spelaeus) we known.

Maybe this could be the longest skull for the entire bear family, which exceeded that of Arctotherium angustidens. Reply

Post # 134 with information of prehistoricfauna.com says that the dimensions of Ursus ingressus are length - 2,3 m, height - 125 сm, weight - 100-300 kg.

I think those dimensions are wrong if you compare the dimensions with such a huge Skull 57,14 cm long, it was a huge Bear for sure at least 900 kg. 

It would be great to know its estimated size and weight. Reply

I think it is the huge variety of the size for this Cave bear species.

The largest specimen was likely over a ton, and I would like to know the largest skull for Arctotherium angustidens. Reply

The skull of the Cave bear is much more vaulted. Reply

OK; I'm just trying to absorb all of this.
Ursus ingressus - length 2.3 m ( 7 feet 7 inches ) long and 300 kg ( 661 pounds ) - grizzly size.
 
Ursus ingressus skull length 57.14 cm ( 22.5 inches ).
Alaskan brown bear - 19 and 13/16 inches.
Polar bear - 18 and a half inches long. 
 
900 kg ( 1,984 pounds ) sounds right to me. Reply

It would be interesting to see a comparison between the largest specimens of Actotherium angustidens and Ursus ingressus. Reply

I agree GrizzlyClaws. That would be awesome! Reply

What exactly would we like in the comparison? Bone to bone comparisons? Reply
