dermosupraoccipital
the superficial, paired dermal bone covering the supraoccipital with which it may fuse. In many Teleostei it is a hinge for the skull articulation with the circumorbital ring. Siluridae have a posterior toothed process that secures the nuchal disc. Also called parietooccipital, postparietal or dermal supraoccipital
