It's a weird fight, a giant bear vs a giant boar. This is quite simply, the largest bear ever discovered and by default, a contender for the largest carnivorous land mammal ever to live. Arcotherium Is heavier and stronger, Daeodon Is faster and he has a larger mouth to bite. It lived primarily in South America during the Pleistocene epoch, some 2.5 million to 11,000 years ago. One of the amazing things about Andrewsarchus is that it lived at a time when mammals were just beginning to achieve giant sizes—the Eocene epoch, from about 45 to 35 million years ago. A humerus of A. angustidens from Buenos Aires indicates that the big males of this species would have weighed 2.2 tonnes, standing 4,3 meters (14 feet) tall, making it the largest bear and largest carnivorous land â¦ Paleontology student. You don't need to be a rocket scientist (or an evolutionary biologist) to conclude that the jaws of Andrewsarchus were immensely strong; otherwise, there would have been no reason for it to evolve with such an enormous, elongated skull. BrotherBear wrote:There have been giants living on this planet; including gigantic mammalian land-based predators. 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. I vote for the elephant after a very hard fight. Given its tooth structure, the musculature of its jaws, and the fact that its single skull was discovered along the shoreline, some scientists speculate that Andrewsarchus fed mostly on hard-shelled mollusks and turtles. The oldest dated confirmed remains are those of A. angustidens from Buenos Aires, Argentina, dating to the Ensenadanepoch, 1.76 tâ¦ In fact, it was a series of reconstructions patterning its body after the better-known Mesonyx that led some paleontologists to the conclusion that Andrewsarchus was a multiton predator.

Classification: Chordata,â â¬Mammalia,â â¬Artiodactyla. Bob Strauss is a science writer and the author of several books, including "The Big Book of What, How and Why" and "A Field Guide to the Dinosaurs of North America. However, that weight estimate drops dramatically if one considers the possibility of other, less bulky Andrewsarchus body plans.

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. This bear was so massive that scientists believe it regularly weighed between 2â¦ Andrewsarchus is one of the world's most tantalizing prehistoric animals: Its three-foot-long, tooth-studded skull indicates that it was a giant predator, but the fact is that we have no idea what the rest of this mammal's body looked like.

Arctotherium is composed of 5 South American species - of which A. angustidens is the earliest, largest, and apparently most predatory - and is the sister clade of Arctodus; the two are in turn part of the clade Tremarctinae which further includes Tremarctos (spectacled bear and kin) and Plionarctos (Soibelzon and Schubert 2011). Andresarchus has a larger skull than other giants, like Megistotherium and Sarkastodon And a larger skull than Arctotherium. Big males of this species would have weighed more than 1,500 kg (3,307 lb) and standing at least 11 feet (3.4 meters) tall on the hind-limbs. If one naively extrapolates from the size of its skull, it's easy to come to the conclusion that Andrewsarchus was the biggest predatory terrestrial mammal that ever lived. 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.
