[10][16][17] Others point out that nitrogen-15 bone analysis cannot distinguish between hypercarnivores and omnivores that ate a significant amount of animal matter,[18] that the species would have had a varied diet across its range,[19] and that the features of the skull and teeth match modern omnivorous bears and it was probably an omnivore with northern individuals having a similar diet to Alaskan brown bears.[2]. In folklore, giants (from Latin and Ancient Greek: gigas, cognate giga-) are beings of human appearance, but are at times prodigious in size and strength or bear an otherwise notable appearance.

In a recent study, the mass of six A. simus specimens was estimated; one-third of them weighed about 900 kg (1 short ton), the largest 957 kg (2,110 lb), suggesting specimens that big were probably more common than previously thought. Based on this evidence, A. simus was suggested to have been highly carnivorous and as an adult would have required 16 kg (35.3 lb) of flesh per day to survive. As they are solitary animals, you must have one cage for one porcupine. The short-faced bear is an extinct bear genus that inhabited North America during the Pleistocene epoch from about 1.8 Mya until 11,000 years ago.

Because its long legs enabled it to run at speeds of 50–70 km/h (30–40 mph), an alternative hypothesis is that it may have hunted by running down Pleistocene herbivores such as wild horses and saiga antelopes, and even prey such as mammoths, an idea that at one time earned it the name "running bear".

[10] A. simus, according to these arguments, was ill-equipped to be an active predator, leading some to conclude that it was a kleptoparasite,[10] using its enormous size to intimidate smaller predators, such as dire wolves, saber-tooth cats, and American lions, or chase them from their kills and steal their food. The lifespan of wild Indian crested porcupines is unknown, but the oldest known captive individual was a female that lived to be 27.1 years old. [20] However, during pursuit of speedy game animals, the bear's sheer physical mass and plantigrade gait would be a handicap; modern brown bears can run at the same speed but quickly tire and cannot keep up a chase for long.
