Diagnosis
ReferenceDiagnosis
O. P. Hay 1908A family of Amphichelydia. Carapace with costals articulated to the peripherals by close sutures and by gomphosis of ends of ribs. Plastron joined to the carapace by sutures and by narrow axillary and inguinal buttresses; the former ascending to the first costal, the latter attaining the borders of the fifth and sixth costals at their junction. In Helochelys the union of carapace and plastron probably less intimate. Mesoplastrals meeting broadly at the midline, not much expanded toward the outer ends. Exposed surfaces of carapace and plastron tuberculated or shagreened. Intergulars and inframarginals present. Skull elongated and pointed; the bones mostly finely tuberculated. The cervical vertebrae are biconcave. Coracoids
distally expanded.
A. R. Milner 2004Primitive cryptodires sharing one synapomorphy, namely pterygoids separated by anteriorly elongate basisphenoid
T. R. Lyson and W. G. Joyce 2011‘‘Pleurosternidae’’ refers to the most inclusive clade containing Pleurosternon (orig. Platemys) bullockii Owen, 1842 but not Baena arenosa Leidy, 1870 or any species of Recent turtle.

Oblong skull shape (length is significantly greater than maximum width); rectangular basisphenoid; anterior plastral lobe larger than posterior plastral lobe.
