Physical properties
Hardness: 5 (Enamel), Color: Cream/Light tan, Luster: Vitreous to dull, Structure: Triangular blade with lateral cusplets and a distinct root, Specific Gravity: ~2.8-3.0
Formation & geological history
Formed through permineralization where organic tissue is replaced by minerals like apatite or silica in marine sedimentary environments. Likely Cenozoic era.
Uses & applications
Scientific study (paleontology), jewelry making, and collector specimens.
Geological facts
Shark teeth are the most common fossil because sharks lose thousands of teeth in a lifetime and their cartilage skeletons do not fossilize easily.
Field identification & locations
Identified by triangular shape and root structure. Commonly found on beaches or in riverbeds near coastal plains, specifically in states like Florida and the Carolinas.
