Acynodon adriaticus
Taxonomy
Acynodon adriaticus was named by Delfino et al. (2008) [preserved in a lithified, laminated carbonate with crushing but some 3D relief]. Its type specimen is MCSNT 57248, a partial skeleton (complete skull with lower jaws, part of the hyoid apparatus and pectoral girdle, right forelimb, the first 10 vertebrae, some ribs, and several dorsal osteoderm), and it is a compression fossil. Its type locality is Villaggio del Pescatore, which is in a Campanian/Campanian lagoonal/restricted shallow subtidal limestone in the Aurisina Formation of Italy.

|---|---|---|
| M. Delfino et al. 2008 | Acynodon adriaticus differs from A. iberoccitanus and A. lopezi in the following set of characters: absence of interorbital ridge; postorbital bar extremely short and blunt with postorbital and jugal almost touching; presence of a sagittal ridge on the parietal (slightly extending to the interorbital area); dorsal surface of squamosal smooth; frontal and parietal have a concave dorsal surface; rim of the supratemporal fenestra thickened; palatines slender and sagittally grooved; palatopterygoidal suture far from the caudal angle of the suborbital fenestra; medial quadrate condyle hooked; very elongate suborbital fenestra extending anteriorly to the level of the fifth or sixth maxillary alveolus and posteriorly to the level of the largest maxillary alveolus (the penultimate alveolus); maxillary edge downturned and arched the level of the largest maxillary alveolus; posterior molariform teeth smooth, without mesiodistal apical crests horseshoe-like or simply tall. |
