Considering living predators ( non-prehistoric ), which carnivorous animals are the greatest bone-crushers? How do they compare with each other?
Based solely on my own thoughts, not science as I've not yet researched, my thoughts are ( 1 ) hyena ( 2 ) canine ( 3 ) bear ( 4 ) big cat. I have no idea where some of the reptiles might fit in.

Komodo dragons have a relatively weak bite. Bears have stronger has than big cats overall because they are larger.

They only manage to kill buffalos because of their venomous bite and even then they must wait a few days. As for bears, they might have stronger bites than big cats at the molars and the way they bite is similar to that of dogs. |

I'm unsure where a mustelid like a wolverine might fit in?

www.sciencedirect.com/science/article/pii/S207815201630027X Ussuri brown bear: In the first place a bear eats meat from croup and proximal parts of hindlegs of an animal, as well as internal organs. The bear does not touch the contents of the stomach and intestines of the ungulate. Then the bear eats meat from other parts of the body; after finishing with the meat it eats the skin, distal parts of limbs, head and small bones. It eats soft antlers of ungulates completely and bites off tips of hard antlers. In the valley of Serebryanka River in April 1983 V.A. Palkin found a female red deer killed and covered by a bear; the predator has only eaten the embryo from the red deer (from the archive of the Sikhote-Alin Nature Reserve). Usually a bear leaves behind partially consumed limb bones of large animals, upper and lower jaws, and parts of the spinal bone; sometimes pelvic bones, shoulder bones and ribs. With a shortage of feed (in winter and early spring) bear consumes carcasses to a greater extent. A bear that has not fallen into winter sleep fully utilizes animals, including all the bones (Kostoglod, 1976). The smaller the animal eaten by the bear, the better it is utilized. For example, a brown bear ate a musk deer in summer, leaving behind only the lower jaw, two cuspid teeth of the upper jaw and a few small fragments of shattered limb bones. Usually the bones that a bear eats are not digested and remain intact. In two places in the Sikhote-Alin Nature Reserve we found excrement of a brown bear containing homogeneous white mass with minor inclusions of wool of ungulates. They were dated to the end of March. Chemical analysis of the samples showed that these were digested bone remains, with domination of calcium oxide (31.2%) and phosphorus (21.6%). These substances could be formed in the intestines of the animal in an alkaline medium by restoring the phosphate salts formed in turn by dissociation of bone substance in the acidic environment of the stomach. Dissolution of the bones of mammals in the stomach is possible only when a bear is feeding on bones exclusively, without other food components (e.g., meat) diluting the stomach acid. This is possible when a bear finds bone remains after it leaves its lair, when the lack of feed forces it to be omnivorous. This assumption is confirmed by the fact that one of the above samples was found close to an almost bare wild boar skeleton that was eaten by a bear. It is also possible that the bones were eaten by bears not in spring, but before hibernation in lair, and the conversion of bone substance was occurring during the winter.

What bear species consume bones? None that i know of. I'm not sure whether Hyena's even consume bones do they? |

www.sabisabi.com/wildfacts/osteophagia/ OSTEOPHAGIA (EATING OF BONES) AND OTHER PHAGIAS The most well-known bone eaters are hyenas. With their powerful jaws, hyenas are able to crush through bone, which is then digested in their incredibly strong stomach acids. The crushing power of their jaws comes from huge jaw muscles which attach to a ridge that runs along the top of the hyenas’ skull.

We found the carcass of a deer and put the remains in front of the camera to see what would come. All that was left when the remains were placed here were three legs. It took about a week before anyone visited. Then, we got a visit from the mama bear and her cub. They stayed for about five minutes, crunching some of the bones and eating the marrow. The next day, there was a visit by the big male bear and a female who is hanging out with him. I hope this means there will be newborn cubs next year!
Although the diet of the black bear is 90% vegetarian, they do eat meat when they can get it. Carcasses are easy to scavenge, so bears will investigate them.

So, thus far, we know that both the American black bear ( Reply #12 ) and the brown bear ( Reply #6 ) occasionally feed on bones.

Neither have I.Polar bears eat mainly blubber after they have slice open the thick hide of their victims. |
