Physical properties

Hardness 5 on Mohs scale (for fossilized enamel and dentin), gray to brownish-black color, vitreous to dull luster, dense compact structure.

Formation & geological history

Formed through permineralization where minerals like silica or apatite replace original organic material over millions of years in marine sedimentary environments.

Uses & applications

Valuable for paleontological study, educational displays, jewelry, and fossil collecting.

Geological facts

Shark teeth are continuously shed during a shark's lifetime, resulting in abundant fossil deposits found globally in ancient marine strata.

Field identification & locations

Easily identified by its distinct triangular shape, serrated edges, and glossy enameloid surface; commonly found in river gravels, coastal exposures, and quarries.
