This site contains all about Shark teeth fossils.
Identification of most sharks are found through a combination of tooth counts and tooth shapes. Teeth can even lead to the identification of shark species like the requiem shark. The fossilized records of teeth helps illustrate evolutionary history, and isolated teeth are used to study and analyze specific linear measurements of the species. In order to identify teeth and specific information about the teeth, research can be done on a shark tooth. This research may uncover many different aspects about the tooth itself, and the shark species. This proves complicated, however, due to the fact that most fossilized teeth are found mixed and scattered. To collect information on basic-life history and get dispersal estimates of a shark tooth, molecular-based technology is very efficient. To further shark population studies, collection of mtDNA can be extracted from shark jaws and teeth. To study the caries-reducing effect in sharks, studies are done on the fluorine atoms that are bound covalently to calcium atoms in the teeth. Each tooth has a complex fluorapatite structure enameloid. In order to reduce effects of deterioration in the teeth, it is useful to sample only the surface of the enameloid of the tooth for this specific research. Studying and researching shark teeth betters our understandings of shark feeding behaviors, evolutionary changes, and mechanisms. This helps us to identify the teeth, and even the species.
