Physical properties

Hardness of 5 on Mohs scale due to mineral replacement. Color ranges from tan to brown, with a smooth enameloid surface and fibrous dentin structure.

Formation & geological history

Formed through the process of permineralization where organic tooth material is replaced by minerals like silica or apatite over millions of years.

Uses & applications

Prized by fossil collectors, educational displays, and occasionally used in handcrafted jewelry.

Geological facts

Shark teeth are shed in the thousands by a single shark over its lifetime, making teeth the most common shark fossil found worldwide.

Field identification & locations

Identify by the distinct triangular or curved blade shape and smooth cutting edges. Commonly found in riverbeds, coastal cliffs, and marine sedimentary layers.
