Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| O. P. Hay 1908 | Lower jaw with broad, flat crushing-surface and long symphysis; the tip not beaked. Carapace resembling that of Caretta caretta but less pointed behind. None of the anterior peripherals suturally articulated with the costal plates, rib-pits of most of the peripherals in the hinder half of these bones. The eleventh peripheral with pit for rib of eighth costal. Plastron not well known, but believed to have a narrower connection with the carapace than in Osteopygis. Limbs not well known, the humerus and femur supposed to have about equal development, with tendencies toward the structure of the same parts in Cheloniidae. |
