Collection: All Shark Teeth

Sharks continually shed their teeth. some sharks shed approximately 35,000 teeth in a lifetime, replacing those that fall out. There are four basic types of shark teeth: dense flattened, needle-like, pointed lower with triangular upper, and non-functional. The type of tooth that a shark has depends on its diet and feeding habits.

The most ancient types of shark-like fish date back to 450 million years ago, during the Late Ordovician period, and are mostly known by their fossilized teeth and dermal denticles. However, the most commonly found fossil shark teeth are from the Cenozoic era (the last 66 million years).
