actually, i do believe the giant heads are more like selfmade replica to scrare of superior predators, the rotten skull of diablos on plum daimyo should be fossilised if it were to be a ancient species thus it shoudlnt rot at all.

" All the other crabs have huge skulls and there is a giant zamtrios skull in the frozen seaway, a laoshan one in polar sea and a a bit more odd looking skeletons like the weird kelbi/kirin one in forest and hills"

uhm.. there is a lao skeleton on polar sea? also a giant zamtrios skull? i always took it for a unknown monster skull.
