Ctenochelys is an extinct genus of Cryptodira, which existed during the Cretaceous period, and lived in shallow waters. Its fossils have been found in the Ripley Formation in central Alabama, USA. It was first named by C.H. Sternberg in 1904, and contains four species, C. stenopora, C. acris, C. procax, and C. tenuitesta.
Species[edit source | edit]
- 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. The two genera are similar in carapaces.
- Ctenochelys acris was first named by Zangerl in 1953.
