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.
