If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| O. P. Hay 1908 | Skull resembling that of Baena, but with the temporal region less extensively rooft over, the squamosals not coming into contact with the parietals. Jugals excluded from the rims of the orbits. Triturating surfaces of the maxillae transversely broad and concave. Choanae opening between the orbits, and at nearly one-third the distance from the snout to the occipital condyle. Shell unknown. | |
| E. S. Gaffney 1972 | Eubaenine with expanded triturating surface, smoothly convex, no high tomial ridge, development ofincipient secondary palate by medial extension of triturating surfaces; preorbital skull length long compared with that of Plesiobaena; cheek emargination not reaching lower level of orbit; lateral constriction of maxillae forming distinct "snout"; skull roof overlying CRISTA SUPRAOCCIPITALIS ending in blunt point; jugal prevented from exposure in orbital margin by meeting of maxilla and postorbital; fronto-parietal suture curved. | |
| Y. Rollot et al. 2018 | a member of Baenidae based on the presence of a wedge-shaped skull and a well-developed pterygoid-basioccipital contact |
