The human skull consists of 22 bones—eight cranial bones and fourteen facial skeleton bones.
Flat bones classically include some of the bones of your skull, face, rib cage, shoulder, and pelvis. It's important to note that many of these bones aren't truly flat and have a curve to them so the name 'flat bone' is a bit of a misnomer.
The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, hip bone (coxal bone), sternum, ribs, and scapulae.
