Physical properties

Hardness varies around 5 to 7 on the Mohs scale depending on the replacing minerals; Color ranges from dark brown, grey, to black; Luster is dull to vitreous; Crystal structure is microcrystalline quartz or apatite replacement.

Formation & geological history

Formed through the process of permineralization or replacement where organic material is slowly replaced by minerals like silica or calcium phosphate over millions of years.

Uses & applications

Educational purposes, scientific research, and fossil collecting.

Geological facts

Fossilized teeth are among the most common vertebrate fossils found because enamel and dentin resist decay much better than soft tissues.

Field identification & locations

Found in sedimentary rock layers, riverbeds, and coastal cliffs worldwide. Collectors often look for distinct shapes resembling claws or teeth, sometimes testing with a microscope or UV light.
