Corsochelys
''Corsochelys'' is an extinct genus of sea turtle that lived in the Late Cretaceous (Campanian). Zangerl (1960) named the type species (and currently only species; ''C. haliniches''), based upon remains found in Alabama within the Mooreville Chalk Formation (the lower part of the Selma Group).〔Hiryana R. 1997. Distribution and diversity of Cretaceous chelonioids. In: ''Ancient Marine Reptiles'' (eds.) Callaway JM, Nicholls EL. Academic Press. pp. 225-241.〕
==Description==
''Corsochelys'' is a basal dermochelyid.〔 As with other basal chelonioids (such as ''Santanachelys'' and ''Toxochelys''), ''Corsochelys'' possesses a large foramen interorbitale with a narrow processus inferior parietalis, which indicates that the genus possessed developed, salt-excreting lachrymal glands.〔(Hiryana R. 1998. Oldest known sea turtle. ''Nature'' 392:705-708. ) Retrieved on June 20th, 2008.〕 In addition to its similarly to these genera, ''Corsochelys'' retains a carapace with minimally reduced coastal plates.〔(2004. Lehman TM, Tomlinson SL. 2004. ''Terlinguachelys fischbecki'', a new genus and species of sea turtle (Chelonioidea: Protostegidae) from the Upper Cretaceous of Texas. ''Journal of Paleontology'' 78(6): 1163-1178 ) Retrieved on June 20th, 2008.〕 Like the larger ''Archelon'', ''Corsochelys'' had channels penetrating the subphyseal plate from bone into the cartilage above,〔(Snover ML, Rhodin AGL. 2007. Comparative ontogenetic and phylogenetic aspects of chelonian chondro-osseous growth and skeletochronology. In: Wyneken J, Godfrey M, Mels V. (eds.). ''The biology of turtles''. USA: CRC Press pp. 17-43. ) Retrieved on June 20th, 2008.〕 much like the living leatherback turtle. This means that ''Corsochelys'' would have reached their large size quickly through fast skeletal growth, as with the leatherback.〔
Recently, a dermochelyid that closely resembles ''Corsochelys'' was found in the Maastrichtian deposits of the Ouled Abdoun phosphate basin, Morocco.〔(Tong H, Hirayama R. 2004.
