Ctenochelys (meaning "comb tortoise") is an

extinct genus of marine turtle (Cryptodira, Pancheloniidae), which existed during the Cretaceous period, and lived in the shallow waters of the Western Interior Seaway.[1] Its fossils have been found in the Ripley Formation and Mooreville Chalk of central Alabama, United States.[2] It was first named by C. H. Sternberg in 1904,[3] and contains two species, C. stenoporus[4] and C. acris.[5]

Species

Ctenochelys stenoporus skeletons

Ctenochelys stenoporus is the type species. It was originally thought to be a species of Toxochelys; T. bauri, until Sternberg declared it a separate genus.[3] The two genera are similar in carapaces.[1]

Ctenochelys acris was first named by Zangerl in 1953 and is now thought to be one of the earliest ancestors of modern

cheloniids.[6]
