Description A superb Mosasaur Tooth Fossil embedded in its original matrix, discovered in the Kem Kem Beds of the Cretaceous Period, near Khouribga, in the Kem Kem Basin, Morocco. This authentic specimen represents a tooth from one of the top marine predators of the Late Mesozoic era. Mosasaurs were large marine reptiles closely related to modern monitor lizards and snakes. They dominated the seas during the Late Cretaceous, preying on fish, ammonites, and other marine life with their powerful jaws and robust conical teeth. Fossil Type: Marine Reptile Tooth (Mosasaur) Genus: Indeterminate Mosasaur (family Mosasauridae) Geological Age: Lower Cretaceous – Aptian Stage (~125–113 million years ago) Formation: Kem Kem Beds, Kem Kem Basin, Morocco Depositional Environment: The Kem Kem Beds were formed in a river-dominated deltaic environment with periodic marine incursions. This rich ecosystem supported a diverse assemblage of both terrestrial and aquatic fauna, including dinosaurs, pterosaurs, fish, and marine reptiles like mosasaurs. Morphological Features: Thick, conical tooth with slight curvature Well-preserved enamel and root (where present) Naturally set in original sedimentary matrix for display Notable: Excellent example of a Cretaceous apex predator’s fossil tooth Embedded in matrix for an authentic geological presentation Perfect for collectors, educators, and fossil enthusiasts The exact specimen in the photo is the one for sale Authenticity: All of our fossils are 100% genuine natural specimens and are provided with a Certificate of Authenticity. The scale cube shown equals 1cm – please refer to the image for full sizing. This Mosasaur tooth fossil from the Kem Kem Basin offers a direct connection to one of the most formidable marine reptiles of the dinosaur age—a fascinating and educational piece of ancient natural history.
