🦴 Fossil facts
| Age | Devonian to present. Most collected teeth are Cretaceous to Pliocene (about 100–3 million years old) |
|---|---|

| Composition | Fluorapatite (calcium phosphate); colour comes from the minerals in the surrounding sediment |
How it forms
Sharks shed thousands of teeth in a lifetime. The enamel-coated teeth resist decay, and buried teeth slowly absorb minerals such as iron and phosphate, turning black, grey or brown.
