In the skull (fig. 83) the postorbital processes of the frontal and jugal almost or quite meet.
In some specimens, such as KU 91716, the stripes are discrete and extend from the postorbital region nearly to the vent.
The zygomatic arch is slender, and postorbital processes are not generally well developed.
Belodon has preorbital vacuities and postorbital vacuities, but the orbit of the eye is never large, as in Pterodactyles.
The postorbital constriction is less, rather than more, than the combined length of the upper premolars.
In Cynognathus the postorbital is fused with the jugal, and the supratemporal with the squamosal, forming apparently one bone.
In lateral view the dorsal outline of the skull of primulina is less concave in the postorbital region.
Laterally the parietal meets the medial angle of the postorbital and the medial border of the supratemporal.
It is drawn out laterally into an antorbital process in front of the eye, and a postorbital process behind it.
Near the anteroventral edge of the squamosal there is a small pit, probably related to a postorbital sensory pore in the skin.

Situated behind the socket of the eye.
