What are the signs of a genuine Mosasaurs fossil?

Authentic Mosasaurs specimens show natural surface wear, consistent mineral coloration, and no modern tool marks. Teeth should fit naturally without gaps, and the specimen should carry a certificate of authenticity with documented Moroccan provenance.

How does size impact the value of Mosasaurs fossils?

Larger, more complete Mosasaurs specimens command higher value — a complete jaw section with teeth in place is worth significantly more than a small fragment. Condition, completeness, and presence of original teeth are the main value drivers.

Are your Mosasaurs fossils authentic?

Yes. Every Mosasaurs specimen on this site is a genuine fossil from the Cretaceous phosphate deposits of Morocco, guaranteed authentic and shipped with a certificate of authenticity detailing its geological origin and provenance.

Read the full collecting notes

Mosasaurs were large marine reptiles that dominated the oceans during the Late Cretaceous period, approximately 70 to 66 million years ago. These powerful predators were not dinosaurs but belonged to the family Mosasauridae — marine lizards closely related to modern monitor snakes and lizards.
Our Mosasaur fossil collection includes jaws, teeth, vertebrae, and bone fragments from the phosphate deposits of Morocco. Each specimen is naturally fossilized and 100% genuine, sourced directly from the Oulad Abdoun Basin and other rich fossil beds in Morocco.
Mosasaur fossils from Morocco are world-renowned for their exceptional preservation. The phosphate-rich sediments created ideal conditions for fossilization, preserving fine details of bone structure and surface texture. Whether you are a seasoned collector or new to fossils, our Mosasaurs collection offers specimens for every level of interest.
All specimens are photographed individually so you see the exact piece you will receive. We ship worldwide with full tracking and insurance.
