Fossilized Shark Tooth

Physical Properties

Hardness: 5 Mohs; Color: Tan to cream (likely modern or lightly mineralized); Luster: Vitreous/shiny (enamel); Sharp triangular shape with a distinct root and crown.

Formation & Geological History

Formed via permineralization where minerals from surrounding sediment replace the organic structure of the tooth over thousands to millions of years. Common in marine sedimentary environments.

Uses & Applications

Primarily for educational collections, jewelry (as pendants), and as a hobbyist collectible.

Geological Facts

Sharks lose thousands of teeth throughout their lives, making them some of the most common fossils found in the world. This specific one appears to be a smaller, modern or near-modern specimen due to its light color.

Field Identification & Locations

Identify by looking for a hard, enamelled triangular crown and a porous, wider root. Commonly found on beaches or in river beds where ancient marine deposits are eroding.
