The Face of Anhanguera

No other pterosaurologists reconstruct the face of Anhanguera this way.

Here the nasal (bright green) and jugal (light blue) continue forward toward the rostral tip, laminated to the large (deep green) maxilla. Not much else to say other than all these laminated bones on the rostrum can be seen in taxa as far back as Scaphognathus, its ancestor.

The primary naris (small oval in front of antorbital fenestra and above the jugal curl) is apparently underlain with bone, so it’s there and it’s not. The secondary naris, closer to the tooth-bearing portion of the premaxilla is tiny, easy to overlook, but still attended by the jugal and nasal, as in Scaphognathus.

Something to look for in this and all related taxa.
