Physical properties

Deep brown to black enamel on the crown, light tan or greyish matrix/root. Conical, slightly curved shape. Hardness: 5 (hydroxyapatite replaced by minerals). Luster: Dull to waxy.

Formation & geological history

Formed during the Late Cretaceous period (approximately 66-70 million years ago) through permineralization in marine sedimentary environments.

Uses & applications

Scientific study, educational displays, and private fossil collecting.

Geological facts

Mosasaurs were apex marine predators, not dinosaurs. They could grow up to 50 feet long and are closely related to modern monitor lizards and snakes.

Field identification & locations

Commonly found in the phosphate mines of the Oulad Abdoun Basin in Morocco. Identification is based on the distinct conical shape and the presence of the fossilized root structure.
