Physical properties
Hardness: 5 (Mohs scale), Color: Dark grey to black with tan matrix, Luster: Dull to slightly vitreous, Structure: Multi-layered enameloid over osteodentine
Formation & geological history
Formed during the Cenozoic or Mesozoic era through permineralization, where minerals replace the organic bone/tooth structure in marine environments
Uses & applications
Scientific study, educational collections, and jewelry making
Geological facts
Shark teeth are the most common shark fossils because their skeletons are cartilaginous and rarely preserve, but they can lose thousands of teeth in a lifetime
Field identification & locations
Identify by the distinct shape and layered texture; commonly found in river beds or coastal areas with eroding limestone or phosphate deposits
