There's a new titleholder for the biggest, baddest bear ever found.
A prehistoric South American giant short-faced bear tipped the scales at up to 3,500 pounds (1,600 kilograms) and towered at least 11 feet (3.4 meters) standing up, according to a new study.
The previous heavyweight was a North American giant short-faced bear -- a related extinct species -- that weighed up to 2,500 pounds (1,134 kilograms). The largest bear on record in modern times was a 2,200-pound (998-kilogram) polar bear shot in Alaska in the 19th century.
The South American giant short-faced bear roamed its namesake continent about 500,000 to 2 million years ago and would have been the largest and most powerful meat-eater on land at the time, scientists say...
The bear skeleton, found in Buenos Aires Province, Argentina, in 1935, was recently reexamined by Schubert and study co-author Leopoldo Soibelzon, a paleontologist from Argentina who specializes in South American fossil bears.
By measuring its almost elephant-size humerus, or upper arm bone, the team was able to calculate the size of the rest of the bear's body, Schubert said.
Their analysis also revealed that the animal was an old male that had endured several serious injuries throughout his life...
In South America, Schubert suspects, a glut in prey and a lack of competition combined to make the bear king of the continent...
In North America, the short-faced bear's increasing size may have offered an advantage -- its sheer heft may have scared off saber-toothed cats and other predators from their kills, the researchers speculate.
And the short-faced bear's reign in North America would have also coincided with an explosion in Ice Age megafauna, such as giant ground sloths, camels, and mammoths -- all potential new food sources.

Probably onions would be better, particularly if cookin’ ‘em up.
Bigfoot ancestor perhaps?
