Ocepechelon is an extinct genus of giant protostegid sea turtle known from the Late Cretaceous (late Maastrichtian stage, 67 Myr) of Morocco. The feeding apparatus of Ocepechelon, a bony pipette-like snout, is unique among tetrapods and shares unique convergences with both syngnathid fishes (unique long tubular bony snout ending in a rounded and forward directed mouth) and beaked whales (large size and elongated edentulous jaws).
