E. A. Cadena et al. 2012A ‘‘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. 2015Podocnemidids 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.
