Toxochelys (TOKS uh KEE leez[1]) is an extinct genus of marine turtle from the Cretaceous period. It is the most commonly found fossilized turtle species in the Smoky Hill Chalk, in western Kansas.[2] Toxochelys was about 2 m (6 ft) in length. There are five known species in the genus: Toxocheys bauri, Toxochelys browni, Toxochelys latiremus, Toxochelys weeks, and Toxochelys moorevillensis.[3] Phylogenetic analysis shows that Toxochelys belong to an extinct lineage of turtles transitional between modern sea turtles and other turtles.[4]
