This is an fossil jaw of mosasaurus platecarpus from the phosphate deposits near, khouribga, morocco. It is a portion of the mandible (lower jaw) from the right side of the skull. The specimen shows off the foramen, and contains nine fully visible teeth and a few unerupted teeth. Whether or not these teeth belong to this jaw is up for some debate and we suspect some may have been imbedded for a more aesthetic piece. There are almost a dozen mosasaurs described from these deposits, but based on the teeth it appears to be from the species, prognathodon anceps. Mosasaurs are a family of enormous marine reptiles that truly dominated the seas 90 million years ago. They ruled during the last 20-25 million years of the cretaceous period. With the extinction of the ichthyosaurs and decline of plesiosaurs, mosasaurs diversified to become prolific apex predators in nearly every habitat of the oceanic world. This item is made of matrice, cristaux, gros cristaux, skutterudite, dent, assiette, crétacé, mosasaurus sp, upper cretaceous, mosasaur jaw, mosasaurus jaw, natural fossil and fossil paleontology.
