The Giant Short-Faced Bear
Arctodus simus
The Fastest Running Bear That Ever Lived
Also called the bulldog bear, the giant short-faced bear (Arctodus simus) was undoubtedly the fastest running bear that ever lived. Rangier and longer legged than any bear today, it was about five feet at the shoulders when walking and stood as tall as 12 feet on its hind legs. Unlike pigeon-toed modern bears, its toes pointed straight forward, enabling it to walk with a fast, purposeful gait.
It probably could run over 40 miles per hour despite weighing over 1500 pounds.
On 4 feet, he was 5½ to 6 feet at the shoulders.
With the front legs straight, the skeleton is 66 inches to the top of the shoulder blades (the big shield-shaped shoulder bones). If short-faced bears had a hump of muscle on the shoulders, he could have been as much as 6 feet at the shoulders.
On 2 legs, he stood 11 to 12 feet tall.
From the crown to the hip joint and down to the heel is 134 inches. That’s 11 feet, 2 inches standing up looking at you or peering down through a basketball hoop. He could look up and bite a branch 12 feet high.
He could reach up 14½ to 15 feet.
He could reach 2 ½ to 3 feet higher with a paw than he could reach with his mouth. This skeleton measures 72 inches from the center of the shoulder blade to the tips of the toes (adding 2 inches for the missing claws). Subtracting 42 inches from the center of the shoulder blade to the tip of the nose, this bear could reach 30 inches above his up-stretched nose—to at least 14½ feet. If he rotated his shoulder upward a few inches, he could reach even higher. Ice Age campers had to hang their food higher than campers do today.
