Americhelydia is a clade of turtles that consists of sea turtles, snapping turtles, the Central American river turtle and mud turtles, supported by several lines of molecular work.[4][5][6] Prior to these studies some morphological and developmental work have considered sea turtles to be basal members of Cryptodira and kinosternids related to the trionychians in the clade Trionychoidea.[7][8] Americhelydia and Testudinoidea, both clades within Durocryptodira (hardshell turtles), split a part during the early Cretaceous.[9][10]
