Mudge discovered the type specimen (a partial skull – Figure 4) of Toxochelys latiremis, which was also named by Cope (). Toxochelys (Figure 5) was about the same size as a modern Green turtle, much smaller than Protostega, but appears to have been the most abundant marine turtle (Figure 6) in the Western Interior Sea. The presence of young mosasaurs in the formation suggests that mosasaurs were viviparous and gave birth hundreds of miles out to sea, as Niobrara was in the middle of the Western Interior Seaway at the time. [7] Juveniles would have been vulnerable to predation by the many large mid-ocean predators, so it is likely that mosasaurs lived in groups rather than solitarily.

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.
