The supratemporal fossae are surrounded by bone on all sides, and the parietals, and often also the frontals are united.
These lie below and to the outer side of the supratemporal fossae.
supratemporal, infratemporal, and post-temporal fossae occur, but no interparietal foramen.
In Cynognathus the postorbital is fused with the jugal, and the supratemporal with the squamosal, forming apparently one bone.
The supratemporal arcade is imperfect, while the infratemporal arcade is complete.
Laterally the parietal meets the medial angle of the postorbital and the medial border of the supratemporal.
The supratemporal is thus wedge-shaped and located between the parietal and the postorbital.
The posterior edge of the supratemporal protrudes as a convex border slightly behind the end of the parietal, and measures 3.0 mm.
Medially, the concave margin of the postorbital meets the supratemporal for about 3.5 mm.
Dorsally, the squamosal meets the anterior half of the tabular and the lateral border of the supratemporal.
