Prionochelys is an extinct genus of pancheloniid from the Mooreville Chalk and Eutaw FormationsofAlabama. It consists of a single species, P. matutina.[1]
Prionochelys was originally assigned to the family Toxochelyidae.[1] A 2018 paper found it to be on the stem of Cheloniidae, the family to which most modern sea turtles belong, forming a monophyletic grouping with Ctenochelys and Peritresius.[2] In 2019, Gentry et al. assigned Prionochelys to the extinct Ctenochelyidae family.
