Ctenochelys is an extinct genus of Cryptodira, which existed during the Cretaceous period, and lived in shallow waters.^[1] Its fossils have been found in the Ripley Formation in central Alabama, USA.^[2] It was first named by C.H. Sternberg in 1904,^[3] and contains four species, C. stenopora,^[4] C. acris, C. procax, and C. tenuitesta.

Species

Ctenochelys stenoporis 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.^[5]
