Physical properties

Hardness 5-6 on Mohs scale, tan to brown color, glassy or enamel luster, crystalline phosphate structure, specific gravity 2.7-3.0.

Formation & geological history

Formed through the fossilization of shed shark teeth in marine sedimentary environments over millions of years.

Uses & applications

Valued primarily as a collectible specimen, in educational displays, and for crafting jewelry.

Geological facts

Shark teeth are shed continuously throughout a shark's life, resulting in abundant fossilization potential.

Field identification & locations

Identified by its distinctive triangular or curved blade shape and smooth enameloid coating, commonly found in marine sedimentary rock layers and river gravels.
