|---|---|---|
| E. S. Gaffney et al. 2006 | A bothremydid pleurodire of the tribe Taphrosphyini with these unique characters among Taphrosphyini: preorbital region very short with extremely narrow dorsal process of maxilla; wide figure 8-shaped apertura narium externa lying above a premaxilla that slopes posterodorsally to anteroventrally; frontal small and widely separated from orbital margin; broad prefrontal-parietal contact; large quadrate extending anteriorly to cover half of cheek; labial ridge of maxilla deeper than in other Taphrosphyini except Rhothonemys; quadratojugal widely separated from jugal, as in Rhothonemys; anterolaterally facing trough developed on pterygoid, parietal, and quadrate extending anterodorsally from foramen nervi trigemini ventrolaterally to condylus mandibularis. Other differentiating characters are: squamosal with vertical flange in contrast to Azabbaremys; palate dorsally arched, in contrast to Taphrosphys and Labrostochelys; sulcus eustachii with dorsal process, in contrast to Azabbaremys and Labrostochelys; foramen posterius canalis carotici interni formed by pterygoid and quadrate; postorbital lacks medial process and postorbital wall open, in contrast to Arenila and Nigeremys; condylus mandibularis anterior to condylus occipitalis; fossa pterygoidea absent. |
