Physical properties

Formation & geological history

Formed through permineralization of aquatic reptile teeth in marine sediments during the Late Cretaceous period (approx. 66 to 100 million years ago).

Uses & applications

Collecting, educational study, and jewelry (often for pendants).

Geological facts

Mosasaurs were apex marine predators, not dinosaurs, but large aquatic lizards related to modern monitor lizards. They could reach lengths of up to 50 feet.

Field identification & locations

Commonly found in the phosphate mines of Morocco. Field identification is based on the conical shape, presence of enamel, and the distinct root structure if preserved.
