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.
|T. R. Lyson and W. G. Joyce 2011||‘‘Paracryptodira’’ refers to the most inclusive clade containing Pleurosternon (orig. Platemys) bullockii Owen, 1842 and Baena arenosa Leidy, 1870 but not any species of Recent turtle.
Canalis caroticus internus located halfway along suture between pterygoid and basisphenoid; interpterygoid vacuity absent; distinct thickening of plastron medial to inguinal buttress.
|W. G. Joyce and J. Anquetin 2019||Paracryptodires can be differentiated from all other turtles by symplesiomorphically exhibiting a midline contact of the nasals and modest lower and upper temporal emarginations, lacking a midline contact of the prefrontals, and possessing large mesoplastra with a midline contact, and by apomorphically exhibiting a dense surface texture that covers the skull and shell, a foramen posterius canalis carotici interni located halfway along contact between pterygoid and basisphenoid, and thickenings of the plastron medial to the bridges.|
