Physical properties

Hardness varies depending on permineralization (often Mohs 5-7 if replaced by quartz/silica); brownish-red to dark brown color; vitreous to dull luster; amorphous crystal structure due to fossilization

Formation & geological history

Formed through permineralization where organic tooth material is gradually replaced by minerals like silica or iron oxides over millions of years, typically dating from the Mesozoic Era

Uses & applications

Valuable for scientific research, museum displays, education, and fossil collecting

Geological facts

Fossil teeth are among the most common dinosaur remains found because tooth enamel is the hardest substance in a vertebrate body and resists decay better than bone

Field identification & locations

Can be identified by characteristic curved tooth shape, serrated edges (in carnivorous theropods), and fibrous or crystalline texture under magnification. Found in fossiliferous sedimentary rock formations worldwide
