Do humans have a Squamosal bone?

What is the Squamosal suture?
Abstract. The squamosal suture is one of the lateral minor skull sutures, separating the parietal and squamous temporal bones. While the phenotypic appearances and sequelae of synostosis of the major cranial vault sutures are well documented, little is reported concerning synostosis of the squamosal suture (SQS).
What is a Dentary bone?
: either of a pair of membrane bones of the lower jaw of most vertebrates, in lower forms being restricted to the distal area but in recent higher mammals forming the body of the mandible.
What is Pterygoid bone?
The pterygoid bone is a flat and thin lamina, united to the medial side of the pterygoid process of the sphenoid bone, and to the perpendicular lamina of the palatine bone. In Men and glires, it constitutes the internal wing of the pterygoid process and merges much more to the other parts in Carnivorous and Glires.

a petty gangster or ruffian. The squamosal is attached dorsoventrally to the posterior part of the parietal and to the lateral part of the prootic. The squamosal is small, its anterior arm slender and pointed. The quadrate and squamosal form the suspensorium by which the lower jaw is connected with the cranium.
