Squamous suture (separates the temporal bone from the parietal bone), Coronal suture (separates the frontal bone from the parietal bone), Sagittal suture (separates the parietal bones) and the Lamboid suture (separates the occipital bone from the parietal bone)
The person is from ages 32-50 when the lambdoidal and sagittal sutures are fused but the coronal sutures are not fused.
Coronal Suture
Parietal bone
The sutures, synarthrotic joints, for the zygomatic bones are between the temporal process of the zygomatic bone and the zygomatic process of the temporal bone, which forms the zygomatic arch.
The sagittal suture separates the top of skull into two (sagitt- means twin), and the coronal suture is in the location that you might find a crown (corona).
Metopic, or frontal, suture - Separates the frontal bone into two halves. Sagittal suture - Separates the two parietal bones. Coronal suture - Separates the frontal bone from the parietal bone Lambdoid suture - Separates the posterior edge of the of the parietal bone form the occipital bone. Squamosal suture - Superior border of the squamous part of the temporal bone. It articulates with the greater wing of the sphenoid; superiorly, it articulates with the parietal bone and posteriorly and inferiorly it articulates with the occipital bone The parietal bones touch all four major sutures (coronal, sagittal, squamous and lambdoid).

coronal sutures
Examples of sutures as joints are found in the bone that make up the cranium which covers the brain. There are 22 bones that form the cranium. There are 11 sutures. The joint is slightly moveable and that gives some flexibility to the cranium. This type of joint is called a synarthrosis.
The parietal bone and occipital bone are connected by the lambdoid suturethe occipital, parietal and temporal bonesWikipedia says: The lambdoid suture (or lambdoidal suture) is a dense, fibrous connective tissue joint on the posterior aspect of the skull that connects the parietal and temporal bones with the occipital bone.The Lambdiod suture connects the occipital bone to the parietal bones and the mastoid part of the temporal bone.The lambdoid suture joins the occipital bone to the parietal bones.occipital and parietal bonesLambdoid suture(s): separates the parietal bones and the occipital bone; it arches across the back of the skull ending bilateral where the parietal and occipital bones meets the temporal bone.occipital and parietal bone
Tissues that are ligaments. These hold bones together at joints called sutures.
