9/3/2023 0 Comments Short faced bear![]() 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 largest bear on record in modern times was a 2,200-pound (998-kilogram) polar bear shot in Alaska in the 19th century. 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). Alaska Fish and Wildlife News.There's a new titleholder for the biggest, baddest bear ever found.Ī 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. Journal of Vertebrate Paleontology 30 (1): 262–275. Demythologizing Arctodus simus, the ‘short-faced’ long-legged and predaceous bear that never was. Bol Univ Nac Aut Mex Inst Geol 101:193-321 ![]() Journal of Vertebrate Paleontology 19(1):169-186 Biostratigraphy of Blancan and Irvingtonian mammals in the Fish Creek-Vallecito Creek section, southern California, and a review of the Blancan-Irvingtonian boundary. Canadian Journal of Earth Sciences 30(5):1007-1013, collected by A.V. Arctodus simus from the Alaskan Arctic Slope. Kurten said that Arctodus was “…by far the most powerful predator in the Pleistocene fauna of North America”. ↑ In 1967 Bjorn Kurten of the University of Helsinki wrote a paper, Pleistocene Bears of North America.Another theory is that it let faster predators make the kill, then bullied them off the carcass. One theory is that the short-faced bear was an active predator, attacking bison directly. When it was standing on its hind (back) legs, the bear was 8–10 feet (2.4–3.0 m) tall. This suggested that the bear was probably bigger than scientists had thought. The original bones are in Chicago's Field Museum of Natural History.Ī recent study estimated the weight of six short-faced bear specimens. It is famous because it was the biggest most-nearly complete skeleton of a giant short-faced bear ever found in America. This animal might have been the largest carnivorous land mammal that ever lived in North America.Īrchaeologists have found only one giant short-faced bear skeleton, in Indiana. The oldest short-faced bear fossils are from the Santa Fe River 1 paleontological sites in Gilchrist County, Florida.Īrchaeologists first found fossils of the short-faced bear in the Potter Creek Cave in Shasta County, California. However, it lived mostly in southern areas, from northern Texas to New Jersey in the east Aguascalientes, Mexico to the southwest and with large concentrations in Florida. The short-faced bear lived in many parts of North America, ranging from Alaska to Mississippi. It became extinct about 11,600 years ago. ![]() Īrctodus simus first appeared during the middle Pleistocene in North America, about 800,000 years ago. At that time, Arctodus simus may have been one of the largest mammals that lived on land and ate meat. The short-faced bear or bulldog bear ( Arctodus) is an extinct genus of bear endemic to North America during the Pleistocene era about 1.8 million years ago (mya) to 11,000 years ago.
