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]
