Diagnosis
Reference | Diagnosis | |
---|---|---|
E. S. Gaffney et al. 2002 | A genus of bothremydid pleurodire with small, triangular skull, orbits facing dorsolaterally as in Cearachelys and Kurmademys; skull roof not extensively emarginate as in Kurmademys; jugal widely (rather than narrowly as in Cearachelys) separated from orbital margin by broad contact of postorbital and maxilla, unique among bothremydids; triturating surfaces triangular as in Cearachelys but in contrast to parallel-sided ones as in the Nigeremys Group, not greatly expanded as in Bothremys; deep pit in triturating surface absent; palatine not extensively exposed in triturating surface as in Bothremys Group; maxilla-quadrate contact absent; eustachian tube separated by bone from incisura columellae auris; incisura columellae auris completely enclosed by bone; quadrate-basioccipital contact present as in other Pelomedusoides; quadrate-exoccipital contact present as in other Bothremydidae; supraoccipital- quadrate contact present as in Cearachelys and Bothremys Group, but in contrast to Nigeremys Group; antrum postoticum larger than in Bothremys, Azabbaremys, Nigeremys, but same as in Cearachelys; precolumellar fossa absent as in most other Bothremydidae; foramen posterius canalis carotici interni formed by pterygoid and basisphenoid; foramen jugulare posterius open laterally; occipital condyle formed by exoccipital and basioccipital in contrast to nearly all other Bothremydidae except Kurmademys. | |
M. Martin-Jimenez and A. Pérez-García 2022 | The presence of a jugal restricted from the orbital margin, an open fenestra postotica forming a short slit, and an open foramen jugulare posterius, are an exclusive combination of characters for the clade Cearachelyini |
