Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| I. Miján et al. 2017 | Beneziphius differs from all other members of the family in the following unique combina- tion of characters: ankylosed thickened premaxillae dorsally roofing the mesorostral groove for most of its length (as in Choneziphius, Messapicetus, Ziphirostrum, and other mem- bers of the “Messapicetus clade” sensu Bianucci et al. 2016); presence of a moderately excavated prenarial basin; presence of a medial gap between premaxillary sac fossae; right pre- maxillary sac fossa barely transversely concave (the three latter characters being major differences with Choneziphius); dorsal surface of the maxillae lateral to the prenarial basin covered by excrescences (as in Choneziphius); premaxil- lary crests on the vertex being anterolaterally directed (as in Ziphiinae sensu Bianucci et al. 2016 and members of the “Messapicetus clade”); nasals being not anteriorly longer than the premaxillary crests (differing from Ziphiinae); and nasals lacking an anteromedial excavation (differing from Hyperoodontinae sensu Bianucci et al. 2016). |
