Phylogenetic analysis shows that Toxochelys belong to an extinct lineage of turtles transitional between modern sea turtles and other turtles. Toxochelys bauri Williston,based on the skeleton YPMis a synonym of Ctenochelys stenoporus.
Toxochelys  es un género extinto de tortuga marina que vivió durante el período el género de tortuga más comúnmente hallado entre los fósiles de la Caliza Smoky Hill, en el oeste de Kansas, Estados Unidos.
 Toxochelys medía cerca de 2 metros de longitud. Se conocen cuatro especies de este género: Toxocheys bauri, Toxochelys browni, Toxochelys latiremus y Toxochelys. Toxochelys serrifer: AMNHa partial skeleton (partial skull (maxillae, dentary, pterygoids, right quadrate, frontals, prefrontals) and two peripheral plates).
Its type locality is Niobrara River (coll. Merrill ), which is in a Miocene terrestrial horizon in the Loop Fork Formation of Nebraska. The first report of Toxochelys latiremis Cope (Testudines: Panchelonioidea) from the early Campanian of Alabama, USA.

Toxochelys latiremis Cope, is currently thought to be one of the oldest members of the clade originating from the last common ancestor of all extant species of marine-adapted turtles.
Usually found as partial skeletons ranging in size from 2 to 4 feet long, this Toxochelys is a rare exception. The shell is only about 24 cm ( inches) long, and is the smallest skeleton we have found.
This baby Toxochelys is very finely detailed and includes the complete hip and limb structures articulated as in life. In Toxochelys latiremis (Matzke ) the foramen caroticum laterale (palatine artery) is much smaller than the foramen anterius canalis carotici interni, this is also the case in Ctenochelys acris (Gentry ).
In Toxochelis moorevillensis (Matzke ) this character is variable. Toxochelys is a genus of sea turtle that lived during the late Cretaceous, and is also one of the most common sea turtles that lived in the Western Interior Sea Way, a shallow sea that once submerged the central portion of the North American Continent. As a genus, Toxochelys seems to be in-between modern sea turtles and.
Late Cretaceous marine turtles are rare in Canada, but specimens are known from three formations: Toxochelys latiremis Cope and Protostega sp. from the Pierre Shale, Pembina Member (lower Campanian); Lophochelys niobrarae Zangerl and Chelonioidea genus indet. from the Bearpaw Formation (upper Campanian); Protostegidae genus indet.
and one other taxon from the Niobrara Formation. Toxochelys latiremis Description: >Extremely rare juvenile sea turtle. This fossil Toxochelys specimen is around 75% complete with the whole skull.

Toxochelys latiremis. The prefrontals are thick and strong, the two together nearly square in out-line or a little broader than long. In the nares the two project into a rounded, obtuse angle.
They form the upper margin only of the nares, the maxillary suture evidently running from near the angle of the orbit to the angle of the nares.On the skeleton of Toxochelys latiremis: On the structure and development of the vertebral column of Amia: On two interesting genera of Eocene turtles, Chisternon Leidy and Anosteira Leidy.
