The posterior portion of the premaxillae, including the premaxillary sac fossae and the transverse premaxillary crests, is poorly preserved. The remaining fragments and the underlying maxillae allow a general description of the area: the premaxillary sac fossa is strongly tilted, anteromedially facing (seen on the right side), and the curvature continues on the ascending process of the bone, so that the roughly rectilinear transverse premaxillary crest is anterolaterally directed (

At a level posterior to the end of the premaxillary crest, the lateral margin of the maxilla strongly elevates to form an elongated longitudinal crest, more acute and higher on the right side, with a maximum height just before the antorbital notch. The posterior part of the crest, lowering on the preorbital process, is excavated by a dorsal infraorbital foramen (with a double exit on the right side), and a posteriorly directed foramen is present at the base of the inner slope of the crest, along the suture with the premaxilla. A wide valley separates the maxillary crest from the rostral longitudinal crest of the premaxilla, anterolaterally directed from the prenarial basin.</paragraph>

before the apex of the rostrum. The latter is formed only of the premaxilla, laterally hollowed by a deep sulcus anteriorly following a foramen located at the apex of the maxilla. The lateral margin of the maxilla is less dense and more eroded than the premaxilla; instead of an alveolar groove, there is a shallow depression with an irregular surface, lacking alveoli.
