Archival Presentation & Scientific Provenance
The Apex Predator of the Cretaceous Seas
Over 70 million years ago, Mosasaurus reigned at the absolute summit of the marine food chain. Armed with double-hinged jaws and rows of robust, conical teeth, this 50-foot leviathan was engineered to crush ammonite shells and dominate prehistoric oceans.
Excavated from the phosphate deposits of Morocco's Ouled Abdoun Basin, this authentic crown preserves genuine striations and enamel formed during the age of the dinosaurs. We secure each tooth in an archival 3D floating membrane frame - designed for clean, 360-degree veneration without compromising the fossil's integrity.

Frequently Asked Questions
How do I know this specimen is 100% genuine?
How do I know this specimen is 100% genuine?
Every fossil curated by Primal Slab is guaranteed authentic and unrestored. We source our specimens directly from vetted paleontological field contacts in the Ouled Abdoun Basin of Morocco. Each tooth undergoes strict inspection to verify natural enamel grain, matrix integrity, and absence of synthetic composite fillers. Every order includes an individually numbered physical Certificate of Authenticity.
How does the 3D floating membrane frame work?
How does the 3D floating membrane frame work?
Our archival suspension frames utilize a flexible, ultra-clear silicone membrane that gently clasps the fossil between two layers. This creates a secure, dust-free suspension that allows 360-degree viewing without applying destructive pressure to the enamel or root. The frame snaps securely shut and can be opened if you ever wish to handle the fossil directly.
Will my tooth look identical to the photos?
Will my tooth look identical to the photos?
Because every prehistoric fossil is a unique, 70-million-year-old organic artifact, slight natural variations in size, coloration, and tip wear occur. However, every specimen in Drop 001 is hand-selected to meet our strict quality benchmark: genuine crown integrity, well-defined enamel striations, and zero structural repairs.
