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
J. Anquetin et al. 2017Representatives of the Thalassochelydia are currently diagnosed relative to other turtles by the following derived characters: presence of a long posteroventral process of the parietal that forms the posterior margin of the foramen nervi trigemini and excludes the prootic from that foramen, and the development of a ventrally infolding ridge on the posterior surface of the processus articularis of the quadrate. The presence of three cervical scutes is probably also a diagnostic feature of the group.
