Toxochelys
Toxochelys () is an extinct genus of marine turtle from the Late Cretaceous period. It is the most commonly found fossilized turtle species in the Smoky Hill Chalk, in western Kansas. Description. "Toxochelys" was about 2 m (6 ft) in length. Two species in the genus are recognized, "Toxochelys latiremis" and "Toxochelys moorevillensis". Phylogenetic analysis shows that "Toxochelys" belong to an extinct lineage of turtles transitional between modern sea turtles and other turtles. "Toxochelys bauri" Williston, 1905, based on the skeleton YPM 1786, is a synonym of "Ctenochelys stenoporus".
