Indeed, not only are the remains of Pachycrocuta found in the cave, but the type of damage seen on the Homo erectus bones (and other fossils) is consistent with what is observed in modern hyena dens. Limb bones, for instance, are scarce and represented mainly by shafts; the ends were broken or gnawed off. Thus postcranial remains are rare because the giant hyenas obliterated them, tearing apart the carcasses and cracking the bones, and some of the bones were even swallowed (as shown by rare acid-etched fragments also bearing tooth marks).
Given the destructive power of these hyenas it might be expected that the Homo erectus skulls would be cracked into splinters, too, but there is very little meat on a hominin head. The main fleshy parts of a head are the jaw muscles, tongue, and the brain, the latter organ being something hyenas relish. Given what is known about the way modern hyenas eat and the damage to the Homo erectus skulls, then, Boaz and colleagues were able to reconstruct what might have happened to the poor hominins.

homo erectus couldn't make it on the asian mainland because of hyena/tiger predation and fled to the islands for safety

practically the same dna
american lions were bigger than the others because they weren't pack hunters
pleistocene tiger was also a giant, but much isn't known about them.
cat genetics are relatively unchanged for 16 million years
