American grizzly bears used to live among smilodons, dire wolves, giant short faced bears (Arctodus sinus) etc.

To be honest, its hard to say which one is more aggressive. Both are brown bears, and both are very aggressive. Both interact with other predators. Horribilis does not interact with tigers or leopards. So in my opinion, i would have to agree with Americanus, i would say that Horribilis is a bit more aggressive, but barely.

I see there features of the grizzly bear and the Ussuri brown bear are a bit different. The Ussuri brown bear in that picture looks a bit like a more compact version of the South American giant short faced bear.

The American inland grizzly bear is now my favourite brown bear subspecies after the Tibetan blue bear.

Quote: The skulls from Lasiotus and horribilis have basically the same score, at least the largest ones from Boone and Crockett. True; perhaps we could say ( realistically ) that they are the same size and pretty-much the same bear. I have no doubts that a mature male American grizzly would displace a tiger from his kill. www.redorbit.com/education/reference_library/animal_kingdom/mammalia/1112523651/ussuri-brown-bear-ursus-arctos-lasiotus/The Ussuri brown bear, sometimes called the black grizzly, can be found in many regions including the Korean Peninsula, Kunashiri Islands, northeastern China, Sakhalin, and the Shantar Islands, among other places. It is a subspecies of the brown bear. The Usurri brown bear is thought to be an ancestor of the North American brown bear, and may have traveled to its current locations from Alaska 13,000 years ago.

Compare: Just a question: Am I the only one to notice the Ussuri brown bear has a shorter muzzle than the American Inland grizzly bear?

The more I see a picture of the Ussuri brown bear/ Russian grizzly, the more I see it has difference in features from the American Inland grizzly bear.

As we all here at the Domain understand, these sizes given by GuateGojira are meaningless. I wish that we has someone here who can do comparison pictures. The Ussuri brown bear male averages roughly 600 pounds and the N. American grizzly roughly 500 pounds. The Amur tiger about 400 pounds.

The grizzly between 1975 to 1985 in the chart seems to be the weight of a barren ground grizzly bear.

The grizzly between 1975 to 1985 in the chart seems to be the weight of a barren ground grizzly bear. I learned that when you read in any animal book and see a number written as the "average weight" of a grizzly - forget you ever read it. There is no such animal as the average grizzly. When Park Rangers weigh bears, they take measurements and weights of animals randomly darted for the research. They do not undertake the time-consuming task of seeking out the big dominant males. Any bear ranging from 4 to 5 years old, which is sexually mature, is added into their averages as adult bears. Yet, a male grizzly is not truly a full-grown bear until he is about 10 years old. Younger bears spend their lives hiding from these mature monarch's of the wilderness. Adding the weights of those younger bears is no different than if, in a study of the weight of the average man, 11 and 12 year old boys are included in the study. Another factor is the season. In the spring months, grizzly bears are at their lightest weight due to their long winter sleep. In the autumn, bears are extra-heavy due to fattening up for their winter sleep. So, the right time to weigh a grizzly is during the summer months. Another factor is environment and food availability. Grizzlies that live in remote desert-like environments where foodstuffs is scarse are much smaller than their brothers who live near the coast and feast on salmon. Grizzly bears of such desolate locations normally weigh within the 300 pound range while coastal brown bears can weigh from 800 to well above 1,000 pounds.

Still these barren ground grizzlies which weigh 300 pounds are the most aggressive of their kind.
