Reptilia - Testudines - Trionychidae
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.
|N. S. Vitek and I. G. Danilov 2010||A trionychine, which can be differentiated from all other Cretaceous trionychines with known shells by bigger size, strong nuchal emargination, eight neurals (except “Aspideretes” maortuensis and “Trionyx” kyrgyzensis), unreduced costals 8 (except “Trionyx” kyrgyzensis), lateral lobe of hyoplastron longer than its medial lobe (except “Trionyx” kyrgyzensis), and, probably, absence of the separate anteromedial process of the hypoplastron (except “Aspideretes” maortuensis and “Trionyx” kyrgyzensis); besides that, can be differentiated from species of Aspideretoides by absence of preneural and by sculpturing pattern, and from “Trionyx” kyrgyzensis by presence of sculpturing on plastron.|
