Ctenochelys is an extinct genus of marine turtle (Cryptodira, Cheloniidae), 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 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]
