🌊 Prehistoric Marine-Reptile Display
Mosasaurs were powerful marine reptiles that inhabited the seas of the Late Cretaceous. They were not dinosaurs; they were squamates, related to modern monitor lizards and snakes. Their long jaws and sharp conical teeth made them successful predators.
🛠️ Preparation and Condition
This is an original fossil skull. Repairs made during preparation are present. The display stand shown is included.
🏛️ Professional Display
At about 14 inches long, this skull is a compact display piece for a private collection, office, library or natural-history interior.

Where it comes from
Moroccan Origin
Morocco’s phosphate basins, above all the Oulad Abdoun Basin near Khouribga and the Ganntour Basin near Benguerir, preserve one of the richest marine vertebrate fossil records on Earth.
At the end of the Cretaceous, a shallow sea covered this part of Morocco. Its nutrient-rich waters supported mosasaurs, plesiosaurs, sharks and bony fish, whose bones and teeth were preserved in the accumulating phosphate sediments.
Reported locality for this specimen: Phosphate deposits, Morocco.
III
From the rock
Discovery
Moroccan phosphates are worked in successive layers. As the rock is exposed, fossil bones and teeth appear within the phosphate beds and are recovered before the material is processed.
Large skulls, jaws and skeletons are rare finds within this enormous volume of rock, and must be lifted carefully, often together with their surrounding matrix.
IV
Deep time
Geological Context
The Maastrichtian phosphate beds formed in the final stage of the Cretaceous, shortly before the extinction event about 66 million years ago. Younger phosphate layers continue into the Paleocene and Eocene.
- Period
- Late Cretaceous
- Estimated age
- Approximately 66–72 million years
