---|---|---|
Z. Gasparini 2009 | Gallardosaurus differs from other pliosaurids in the following combination of characters: participation of the premaxilla in the antero-medial margin of the naris. Nasal surpassing the anterior level of the orbits and participating widely in the posterior margin of the naris. Prefrontal expanded rostrolaterally. Frontal excluded from the orbital margin. Parietal with expanded anterior margin. Lateral pillar of the postorbital merging with the jugal and squamosal. Presence of a slit-like anterior interpterygoid vacuity. Cultriform process of parasphenoid convex, exposed in palatal view and closing the anterior interpterygoid vacuity. The basisphenoid is 3 ⁄ 4, and the parasphenoid 1 ⁄ 4 inside the posterior interpterygoid vacuity. Pterygoid flanges high. Basioccipital tuber short. Coronoid area high and surangular short. The jaw articulation is low relative to the tooth row. Neural spine of the atlas and axis fused, forming a wide roof posteriorly, and upwardly oriented. |
