Ursus arctos īrown bears originated in Eurasia and traveled to North America approximately 50,000 years ago, spreading into the contiguous United States about 13,000 years ago. There are two morphological forms of Ursus arctos: the grizzly and the coastal brown bears, but these morphological forms do not have distinct mtDNA lineages. Evolution and genetics Phylogenetics Ĭlassification has been revised along genetic lines. The modern spelling supposes the former meaning even so, naturalist George Ord formally classified it in 1815 as U. Meriwether Lewis and William Clark first described it as grisley, which could be interpreted as either " grizzly" (i.e., "grizzled"-that is, with grey-tipped or silver-tipped hair) or " grisly" ("fear-inspiring", now usually "gruesome").
5.2.4 Grizzlies and various small predatorsĬlassification Meaning of "grizzly".lasiotus), inhabiting Russia, Northern China, Japan, and Korea, is sometimes referred to as the "black grizzly", although it is no more closely related to North American brown bears than other subspecies of the brown bear around the world. On average, grizzly bears near the coast tend to be larger while inland grizzlies tend to be smaller. nelsoni†), and Ungava-Labrador grizzly (formerly U. californicus†), Mexican grizzly (formerly U. gyas)-as well as the extinct California grizzly ( U. middendorffi) and the peninsular grizzly ( U. These include two living populations-the Kodiak bear ( U. In addition to the mainland grizzly ( Ursus arctos horribilis), other morphological forms of brown bear in North America are sometimes identified as grizzly bears. A 500 pound grizzly vs a 500 pound gorilla would probably be a lot closer, though I would still go with the bear's superior weapons and armor.The grizzly bear ( Ursus arctos horribilis), also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America. While a gorilla would be a physical match for just about anything their own size, a "maxed" grizzly is much bigger, and coupled with their claws and pelts, that's the difference. While they are immensely strong, they possess no claws, and their pelt/skin is not terribly tough.
Gorillas max out around 6 feet tall and 500 pounds. Gorillas are pretty big and bad ass, but nowhere near a grizzly. They carry five 3-inch razors built into each hand, are very strong, quite intelligent, and can be quick in short bursts.

Their pelts are incredibly tough (they can shrug off many small-caliber guns), and they have thick skin and a layer of fat under that, so you have to hit them pretty hard/deep to even come close to anything vital.

Grizzlies are frickin huge, up to 10 feet tall and 1,500 pounds for a full grown male. You could definitely make a case for some of the giant herbivores like hippos or elephants because of sheer size, or a crocodile (up to 20 feet long and 2,400 pounds!), but those aren't quite the same kind of "brawler" that we're supposing a bear or gorilla might be.
Grizzly bears are just about the most dangerous land animal around (I'm going to lump polar bears in together with grizzlies).
