Physical properties

Hardness of 5 on Mohs scale (due to mineralization), color ranges from dark grey, brown, to black depending on the minerals in the sediment, vitreous to dull luster, solid triangular structure with visible serrated edges on the blade.

Formation & geological history

Formed through permineralization where the original organic material of the shark tooth is slowly replaced by minerals such as silica, iron, and calcium from surrounding marine sediments over millions of years (Neogene to Cretaceous periods).

Uses & applications

Popular among fossil collectors, used in educational displays, and sometimes crafted into jewelry.

Geological facts

Shark teeth are shed in the thousands by individual sharks during their lifetimes, making teeth the most common shark fossil found worldwide. Megalodon and Great White shark teeth are among the most famous and sought-after specimens.

Field identification & locations

Easily identified by its distinct triangular shape, smooth enameloid surface, and often serrated cutting edges. Commonly found in riverbeds, coastal cliffs, and ancient marine sedimentary deposits such as those in Florida, South Carolina, and Morocco.
