. . "Macrochelys is a genus in the family Chelydridae. It consists of three extant species: Macrochelys temminckii, Macrochelys suwanniensis, and Macrochelys apalachicolae and the extinct M. schmidti and M. auffenbergi (described from the early middle Miocene of Nebraska and the middle Pliocene of Florida, respectively). The genus was considered monospecific until a 2014 study by Travis Thomas divided it into three separate species."@en .
