Fossil Overview

This exceptional Mosasaurus skull fossil is a large, authentic specimen of Prognathodon currii, one of the most powerful marine predators of the Late Cretaceous seas. Measuring 100 cm (39.3 inches), this Mosasaurus fossil comes from the renowned phosphate deposits of Sidi Chennane, Morocco, a location famous worldwide for producing scientifically important marine reptile fossils.

Dating to approximately 70–66 million years ago, this skull illustrates the anatomy that made Mosasaurs apex predators of their ecosystem. The specimen consists of approximately 89% original skull bones from Prognathodon, with the remaining elements restored using real fossil bones from other Mosasaurs for structural integrity. No replicas, casts, or artificial materials are present — every visible element is genuine fossil bone.

A Certificate of Authenticity is available confirming species identification, fossil composition, and professional restoration.

About Mosasaurus Fossils

Mosasaurus fossils represent a group of giant marine reptiles that dominated the oceans at the end of the Age of Dinosaurs. Unlike dinosaurs, Mosasaurs were fully marine reptiles with streamlined bodies, powerful tails, and massive skulls designed for hunting large prey.

Prognathodon species are especially known for:

• Thick, crushing teeth

• Deep, reinforced jaws

• Strong bite force adapted for hard-shelled prey

• A wide skull built for power rather than speed

You can see comparable Mosasaurus fossil skulls in major natural history museums and scientific collections, where they help researchers understand Late Cretaceous marine ecosystems. Institutions such as the Smithsonian National Museum of Natural History and the Natural History Museum in London display related Mosasaur material for research and education.
