Which suture marks the boundary between the Parietal bone and Temporal bone?

Explanation:
The boundary between the parietal and temporal bones is marked by the squamous suture. This suture runs along the side of the skull, where the flat edge of the temporal bone meets the parietal bone. The name “squamous” reflects these flat, scale-like edges that come together there. Sutures are fibrous joints that knit the skull bones and are named for the bones they separate: the coronal suture sits between the frontal and parietal bones; the sagittal suture lies between the two parietal bones; the lambdoid suture lies between the parietal bones and the occipital bone.
