Behind the dentary was a moderately large mandibular fenestra. The dentary projects somewhat posteriorly, forming the edge of the external mandibular fenestra. A foramen called the preantorbital fenestra opened into this recess at the front bend. The lacrimal process constitutes the rostral margin of the reduced antorbital fenestra. The postorbital in side view is excluded from the supratemporal fenestra. There was a large rostral mandibular fenestra and a small, rounded caudal fenestra behind it. The lower jaw has a large external mandibular fenestra. In archosauriforms, the jugal even re-encloses the lower temporal fenestra. The maxilla has a short depression around the lower front of the antorbital fenestra. The mandibular fenestra, a sidewards-facing opening in the lower jaw, was elongated and comparatively small. The main body of the maxilla has no depression around the antorbital fenestra. The external mandibular fenestra, present in prosauropods and some basal sauropods, is entirely closed. This hole is known as a lateral temporal fenestra. One of these is a large triangular antorbital fenestra in the side of the snout. Behind the eye socket a large triangular infratemporal fenestra is present.
