Corsochelys is an extinct genus of sea turtle that lived in the Late Cretaceous (Campanian).

[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.
