The Kodiak bear, on the other hand, commonly reaches sizes of 300 to 600 kg (660 to 1,320 lb), and has even been known to exceed weights of 680 kg (1,500 lb). The bear’s skull measured 27 6/16, making it the largest grizzly taken by a hunter ever recorded. That bear was killed in 2004 by Dennis Dunn and was also taken in Unalakleet, Alaska. Ya know I got to get that straight. The world-record skull was found by a hiker in 1976, and is just 7/16ths of an inch larger. An Alaska man has found his way into the record books for bagging the biggest grizzly bear ever, a beast that stood nearly nine feet tall. He’s still a record he’s just not the world record. The bear was just over one thousand six hundred pounds It stood 12′ 6″ high at the shoulder, 14′ to the top of his head. That bear was killed in 2004 by Dennis Dunn and was also taken in Unalakleet, Alaska. It's the largest grizzly bear ever recorded in the world. A grizzly bear is one of the largest North American land predators and will always tip the scales more than even a large male black bear could. There's a new titleholder for biggest bear ever found—an ancient South American giant short-faced bear that weighed up to 3,500 pounds. The bear beat the previous World Record grizzly score of 26 3/16 by almost a full inch. The world-record skull was found by a hiker in 1976, and is just 7/16ths of an inch larger. In relation to the world record he wound up only being short by 2 inches and uh 2/16ths of an inch which put him at the rank of 145 out of the 347 of the largest, worlds largest bears ever taken. Despite this large variation in size, the diet and lifestyle of the Kodiak bear does not differ greatly from that of other brown bears.
