The squamosal is attached dorsoventrally to the posterior part of the parietal and to the lateral part of the prootic.
The postglenoid and post-tympanic processes of the squamosal are large.
The quadrate and squamosal form the suspensorium by which the lower jaw is connected with the cranium.
The periotic and tympanic are welded together, but not with the squamosal.
The anterior (zygomatic) process of the squamosal is greatly reduced (only about one-third the length of the posterior process).
In no species is the anterior arm of the squamosal in contact with the maxillary.
The exoccipitals also form part of the base to which the squamosal is attached.
In addition the zygomatic ridge of the squamosal decreases in relative size with decrease in actual size of the skull.
The tympanic is united with the periotic but not with the squamosal, and forms a large auditory bulla.
The squamosal is small, its anterior arm slender and pointed.
