Physical properties
Hardness: 5 (Enameloid). Color: Tan, brown, or gray due to permineralization. Luster: Vitreous to dull. Structure: Triangular or blade-like with a distinct root and crown.
Formation & geological history
Formed via permineralization where minerals like calcium phosphate are replaced by groundwater minerals over millions of years (Cenozoic or Mesozoic eras) in marine environments.
Uses & applications
Primarily for collecting, educational specimens, and small-scale jewelry (pendants). No industrial use.
Geological facts
Sharks can lose thousands of teeth in a lifetime, making them one of the most common vertebrate fossils found worldwide.
Field identification & locations
Identified by sharp, serrated or smooth edges and a dense, bony root. Found in coastal regions, riverbeds, and former sea beds.
