Physical properties

Hardness: 5 (enameled surface); Color: Tan, beige, or brown; Luster: Vitreous to dull; Shape: Conical and slightly curved; Structure: Dense hydroxyapatite replaced by minerals.

Formation & geological history

Formed during the Late Cretaceous period (approx. 66-70 million years ago) in marine environments. The biological material was mineralized through permineralization in seabed sediments.

Uses & applications

Scientific study, educational displays, and private fossil collecting. Larger or rare species teeth can be used in unique jewelry.

Geological facts

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

Field identification & locations

Commonly found in the phosphate mines of Morocco. Field identification involves looking for the characteristic conical shape and 'root' texture often found in sedimentary matrix.
