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.
|E. A. Cadena et al. 2012||A ‘‘Shweboemys Group’’ Pelomedusoides turtle (sensu Meylan 1996) known from skull, jaw, shell, and some girdle and limb elements; secondary palate shorter than in all ‘‘Shweboemys Group’’ except ‘‘Shweboemys’’ gaffneyi (per Gaffney and Wood 2002); medial edges of palatal cleft curved as in ‘‘Shweboemys’’ gaffneyi; ventral convexity on triturating surface larger than in all other ‘‘Shweboemys Group’’; eustachian tube separated by bone from rest of fenestra postotica in contrast to all other known Podocnemididae; antrum postoticum extremely small and slit-like in contrast to all other ‘‘Shweboemys Group’’; frontal and prefrontal strongly convex on dorsal surface in contrast to all other ‘‘Shweboemys Group’’; basisphenoid separated from palatines by medially meeting pterygoids as in ‘‘Shweboemys’’ antiqua (per Gaffney and Wood 2002) and S. pilgrimi; basioccipital longer than in Shweboemys pilgrimi; jugal-pterygoid contact prevents palatine-parietal contact. Intergular, gular, and humeral scutes greatly reduced and restricted to the far anterior plastron, pectoral|
|G. S. Ferreira et al. 2015||Podocnemidids with a unique secondary palate among turtles, which is formed by maxillae and palatines and separated on the midline by a narrow cleft; no median maxillary ridge seen in other Podocnemididae; palate with a variable development of the rostral convexity and caudal concavity; palatine making up half or more of secondary palate; fossa orbitalis with extensive caudal pocket behind orbital rim enclosed by the septum orbitotemporale.|
