In many fishes the skull is almost wholly cartilaginous but in the higher vertebrates it is more or less completely ossified, several bones are developed in the face, and the cranium is made up, wholly or partially, of bony plates arranged in three segments, the frontal, parietal, and occipital, and usually closely united in the adult.
Origin: OE. Skulle, sculle, scolle; akin to Scot. Skull, skoll, a bowl, Sw. Skalle skull, skal a shell, and E. Scale; cf. G. Hirnschale, Dan. Hierneskal. Cf. Scale of a balance.
