The calvaria is comprised of the upper frontal, temporal, parietal and occipital bones. As such, the calvaria is bone. Since there is no calvaria which is not bone, the adjective “bony” is superfluous. Just say “The calvaria is intact.”

The skull is the skeleton of the head excluding the mandible. It is composed of the cranium and face.  The cranium is the portion of the skull that encases the brain.
