To put it into perspective, if Arctotherium stood on its hind legs, it could right hook a giraffe in the face. Addendum: at the 2040 kilogram upper estimate, Arcotherium also outweighs a bull giraffe by a small margin, and outweighs a white rhino to boot.

And the giraffe would still kick it once and break half the bones in its body Giraffes are terrifying animals

oh wow yeah that's some good perspective, thanks 0_0

[@troygillis6801]

@@kitchengun1175 a bear that big, probably only 1 bone per kick. Your point still stands of course tho. Girraffes can take a WALLOP to the head and sway their necks to absorb huge damage if needed, I doubt a right hook from anything would be enough to put a giraffe down, save a wrecking ball. Only way that bear is getting it's prey without taking way too much damage is if it tackles it's back from behind, which would probably break it's back with a 3,600 lb bear. If not, it could break the neck with a bite from the same angle. But head on? That bear is gonna die, either during the fight itself or from injuries afterwards.

[@TheLordHighNoob]

@@troygillis6801My guardians have worked in African Game Lodges my entire life, and I've spent thousands of hours in them. I have seen giraffes, and have touched them, and have been licked by them. My living room has a giraffe skull from a bull who died of natural causes. I have some idea of what I'm talking about. Giraffes can kick and do kick with astonishing force. They are megafauna in their own right and getting kicked by one is a death sentence. The impact force would easily decapitate a human - there are some anecdotes of them doing the same to the far more robust lioness. The right hook would not kill a giraffe. They regularly slam their skulls into other giraffes in truly astonishing intra-species combat. It's horrifically brutal to witness in person. However, giraffes are also hunted by lions, and there are prides who specialise in hunting giraffes. Some use truly ingenious tactics like running the giraffe into rocky, unstable terrain, and causing the giraffe to break its legs in the fissures. I still choose Angustidens. Evicting giant ground sloths - who weigh twice that of a bull giraffe, rear nearly as high, and have knives for hands - is an exceptionally impressive feat. Giant ground sloths pummelled rock into caves. That is an impressive punch to survive. Further, Angustidens has an equally impressive punch. They too had significant intra-species combat, and if it's anything like modern bears, it involves a lot of repeated punches to the head and torso from an animal which can lift hundreds of kilos with each arm. Angustidens isn't going to be killed by giraffe's kicks any sooner that it can kill a giraffe.

[@TheLordHighNoob]

@@kitchengun1175As scary as they are, they're also quite skittish. They can run at 60km/h. Why kick you, when they can spot you're a mile away, and then kick the ground till you're a mile and a half away? A giraffe is no where near as scary to me on a game walk as a water buffalo, or an elephant, or - God forbid - a rhino.

Paleoburrows are a crazy concept. Like, imagine digging something that many thousand years ago, and it still exists

[@LordRumshi]

The change in environment is a theory that is expressed as to why all of the large carnivorous mammals went extinct such as the short face bear, smilodon, and dire wolves died out but smaller predators such as gray wolves and grizzlies survived. A belief on how when the likes of woolly mammoths and giant ground sloths disappeared, it made things harder for larger predators to survive as they required larger amounts of meat than gray wolves and grizzlies.

[@ChickensAndGardening]

Yes, in North America anyway, most of the megafauna went extinct towards the end of the last Ice Age (20KYA). This included woolly camels, native horses, glyptodons, mastodons, mammoths, ground sloths, giant beavers. Roughly around the time that humans entered from Asia and started hunting them to extinction.

[@LordRumshi]

@@ChickensAndGardening that has been believed to be another contributing factor of why the likes of the short face bear disappeared towards the end of the last ice age.

Grizzlies ate bigger than most of that extinct list

[@estebancarrasco8086]

Eso lo escuchaste en otro lado de seguro

[@petertaysum8947]

A possible explanation is the north-south axis of the Americas. As the Ice Age ended, fluctuations in the changing climate would have been more dynamic than the Old World (because of its east-west axis). Migration routes of prey animals would be disrupted far quicker than evolution could remedy, and predator populations could not survive. Another factor is the long gestation of Megafauna. Just a few years of poor grazing for the prey, and consequent leaner pickings for the predators, and population decline would soon become exponential. And then them pesky humans show up with their pointy sticks and fire. Imo.

The very highest mass estimates for Arctotherium angustidens are questionable for several reasons; they came from a limb element that had fractured then healed, leading to the bone being much greater in diameter (which is the relevant parameter for gauging weight in land mammals) than it should have been, and the equation used to calculate the mass of the animal was based on obese brown bears in captive setting rather than individuals with a healthy body weight, so that also led to an overestimate.

The iconic short-faced bear (Arctodus simus), also known as the bulldog bear, is a species of bear that originally inhabited North America during the Pleistocene epoch from about 1.8 Mya until 11,000 years ago and was once extinct, but has since been brought back from extinction by what scientists are now duing to bring back the mammoth and has since been reintroduced to the modern forests, open woodlands, and grasslands of North and south America also including alaska and yellowstone to help boost biodiversity. It is one of the most common North American bears and among the most abundant in California. The short-faced bear is often considered to be one of the largest known terrestrial mammalian carnivores that has ever existed, although the Andrewsarchus is much larger. The short-faced bear can weigh about 900 kg (1 short ton) on average, however, the largest male being around 957 kg (2,110 lb) is not uncommon. When walking on all fours, a shiort-faced bear can stand about 5-6 feet (1.5-1.8 m) high at the shoulder, tall enough to look an adult human in the eye. When standing on its back legs, the male short-faced bear can stand up to 12 feet (3.66 m) tall. The short-faced bear is the most carnivorous of all living bears, being able to hunt animals as big as or bigger than itself, making the short-faced bear a brutish predator that overwhelms large mammals with its great physical strength. However, it usually feeds on pigs, peccaries, and other animals smaller than itself, as its limbs, despite being strong, are too gracile for such an attack strategy most of its time. Because its long legs enable it to run at speeds of 50-70 km/h (30-40 mph), it can also hunt by running down herbivores such as wild horses, saiga antelopes, and even prey such as baby mammoths. However, during pursuit of speedy game animals, the bear's sheer physical mass and plantigrade gait is a handicap; brown bears can run at the same speed but quickly tire and cannot keep up a chase for long. The short-faced bear's skeletons do not articulate in a way that would allow for quick turns - an ability required of any predator that survives by chasing down agile prey. It moves in a pacing motion like other living bears, making it built more for endurance than for great speed. The conservation status of the short-faced bear is Least Concern due to successful conservation efforts to bring the animal back and return the the short-faced bear's to there wide natural areas.
