su·tur·al bones

[TA]
small irregular bones found along the sutures of the cranium, particularly related to the parietal bone.

wormian bones

A subset of the small intrasutural bones that lie between the cranial sutures formed by the bones of the skull vault, which are formed due to additional ossification centres in or near sutures. They are regarded as normal variants and may have a genetic component. They have been linked to rapid cranial expansion as they appear in great number in hydrocephalic skulls. They are commonly found in the lambdoid suture and fontanelles but also occur in the coronal, squamosal and sagittal sutures.
