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.

Diagnosis
ReferenceDiagnosis
A. D. Gentry 2018MCL 90100 cm. Specimens can be diagnosed as Prionochelys
matutina based on the presence of a pair of epineurals between neurals 45, the loss
of a cervical keel elevation, and the sharply crested, posteriorly oriented apex of the episuprapygal.
