What is "toxochelys"

Toxochelys (TOKS uh KEE leez) 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. 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. Phylogenetic analysis shows that Toxochelys belong to an extinct lineage of turtles transitional between modern sea turtles and other turtles.
