Physical properties

Hardness of 5 on Mohs scale (due to mineralization). Color ranges from tan and brown to black. Vitreous to dull luster with preserved serrations and enameloid structure.

Formation & geological history

Formed through permineralization where original organic material is replaced by minerals like apatite and silica over millions of years.

Uses & applications

Valued by fossil collectors, educational displays, and sometimes used in jewelry making.

Geological facts

Sharks shed thousands of teeth in a lifetime, making teeth the most common elasmobranch fossil found worldwide.

Field identification & locations

Identified by distinct triangular shape, cutting edges, and root structure. Commonly found in riverbeds, coastal erosion areas, and ancient marine sediment layers.
