From Ouled Abdoun Basin, Morocco, West Africa. From the private collection of Kenneth Machin (1936-2020), Buckinghamshire, UK; his collection of antiquities and natural history was formed since 1948; thence by descent.
The Mosasaur is an extinct, large marine reptile dinosaur with an elongated body, long snout and paddle-like limbs. Found worldwide, they competed with other well-known sea predators of the Late Cretaceous, such as plesiosaurs and ichthyosaurs, for food, existing primarily on a diet of ammonoids, cuttlefish and fish.
