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).[1] DescriptionCorsochelys is a basal dermochelyid.[1] 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.[2] In addition to its similarly to these genera, Corsochelys retains a carapace with minimally reduced coastal plates.[3] Like the larger Archelon, Corsochelys had channels penetrating the subphyseal plate from bone into the cartilage above,[4] 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.[4]Recently, a dermochelyid that closely resembles Corsochelys was found in the Maastrichtian deposits of the Ouled Abdoun phosphate basin, Morocco.[5] References1. ^1 Hiryana R. 1997.
