Andrewsarchus (/ Ë æ n d r uË Ë s ÉËr k É s /) is an extinct genus of mammal that lived during the middle Eocene epoch in what is now Inner Mongolia, China.Only one species is usually recognized, A. mongoliensis, known from a single skull of great size discovered in 1923 during the expeditions to central Asia by the American Museum â¦ BrotherBear wrote:There have been giants living on this planet; including gigantic mammalian land-based predators. Size: Total size uncertain due to lack of â¦ We don't, however, know if the type specimen wound up on the beach naturally or by accident, and there's no reason to rule out the possibility that Andrewsarchus was omnivorous, perhaps supplementing its diet with seaweed or beached whales. The Largest Of Them All: Arctotherium Angustidens. It was assigned to Tremarctinae by Krause et al. Order: Carnivora. Este imponente mamífero llegó a medir cuatro metros y medio de altura en posición erguida (y 1,8 metros en cruz), contando además con un peso estimado entre los â¦ Arctotherium - a giant bear - roughly 3000 pounds. During the 1920s, the swashbuckling paleontologist Roy Chapman Andrews, sponsored by the American Museum of Natural History in New York, embarked on a series of well-publicized fossil-hunting expeditions to central Asia (then, as it still is now, one of the most remote regions on Earth). The elephant could gore the bear or grab/manipulate it with its trunk. This is quite simply, the largest bear ever discovered and by default, a contender for the largest carnivorous land mammal ever to live. It lived primarily in South America during the Pleistocene epoch, some 2.5 million to 11,000 years ago. 10. of 20. It's a weird fight, a giant bear vs a giant boar. Family: Ursidae. A typical representative: Arctotherium angustidens Gervais and Ameghino, 1880. The oldest dated confirmed remains are those of A. angustidens from Buenos Aires, Argentina, dating to the Ensenadanepoch, 1.76 tâ¦ A side attack is the best option, but the bear isnt the most agile animal and the elephant is still larger, and combined with its powerful build and thick skin it should prove too durable. Named By: Wagnerâ â¬-â â¬1837. Anyway, quoting "THE LARGEST KNOWN BEAR, ARCTOTHERIUM ANGUSTIDENS, FROM THE EARLY PLEISTOCENE PAMPEAN REGION OF ARGENTINA: WITH A DISCUSSION OF SIZE AND DIET TRENDS IN BEARS" by Soibelzon and Schubert: vs Kansas River, KS, KUVP C-2427, Humerus (mm): Arctotherium â¦ Restoration Drawing Of Augustidens (Author: Robert Bruce Horsfall, PD) Without mincing words, this was the largest bear ever known. Arctotherium angustidens Arctotherium is an extinct genus of South American short-faced bears within Ursidae of the late Pliocene through the end of the Pleistocene. It measured 3.2 meters and weighed 800â900 kg on average although the largest wouldâve easily weighed 1,500+ kg, maybe even up to a ton or more. The only thing found was itâs skull. This bear was so massive that scientists believe it regularly weighed between 2â¦ The only thing keeping Arctotherium from supplanting Andrewsarchus as the biggest terrestrial mammalian predator was its presumed diet of fruits and nuts.

Unfortunately, given the lack of fossil evidence, paleontologists have yet to determine exactly how strong this mammal's bite was, and how it compared with that of the much bigger Tyrannosaurus rex, which lived about 20 million years before. Welcome Guest. The South American giant short-faced bear (Arctotherium angustidens Gervais and Ameghino, 1880) is one of five described Arctotherium species endemic to South America and it is known for being the earliest, largest, and most carnivorous member of the genus.Here we report an extraordinarily large A. angustidens individual â¦ After its discovery, Andrewsarchus ("Andrews' ruler") was named in his honor, though it's unclear whether Andrews bestowed this name himself or left the task to other members of his team.
