Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. d. Lapparent de Broin 2000 | A pleurodiran podocnemidoid turtle (particularly by the presence of a podocnemidoid fossa, developed retroarticular process crossed by the chorda tympani, inguinal process below the pleural 5, elongated bridge), pre-Podocnemididae by the presence of an enlarged carotid canal; but still primitive, principally by the absence of prolonged pterygoid wings, presence of open incisura columellae auris and Eustachian tube passage, the foramen jugulare posterius not separated from the fenestra postotica, the undifferentiated triturating surface, the articular process not horizontally or upwards directed, the neural 1 still hexagonal short sided posteriorly and the pentagonal neurals 2 and 3, the neural 7 contacting the pleurals 8 and the iliac scar contacting the suprapygal. Apomorphic by its wide anterior truncated snout, large orbits, moderately narrowed interorbital space, short maxilla below the orbits, narrow maxillare and mandibular triturating surfaces just slightly posteriorly widened, widely exteriorly extended oposthotic ventrally below the antrum squamosum. |
