Diagnosis
ReferenceDiagnosis
A. D. Gentry 2018Moderately sized marine turtle similar in size to Ctenochelys stenoporus. Differentiated from Toxochelys Cope, 1873 and Thinochelys Zangerl, 1953 by the presence of keeled neurals, epineurals, and strongly serrated posterior peripherals. Diagnosed from other Cretaceous pan-cheloniids such as Ctenochelys spp. by the highly serrated lateral edges of peripherals 411 and the deeply embayed anterior nuchal emargination resulting in a more distinctly cordiform carapacial outline. Diagnosed from Peritresius spp. by the increased contact between the hyo- and hypoplastron, the relative width of the neuralia, and the presence of eight neurals and one preneural.
