Why do shark teeth turn black?

Why Shark Teeth Turn Black. Most of the time, shark teeth that you find on the beach are black because they're fossilized. In the process of fossilization, the minerals that are naturally in shark teeth are replaced by other minerals that were in the rock or soil where the tooth was buried.

Do megalodons still exist?

Megalodons are extinct. They died out about 3.5 million years ago. And scientists know this because, once again, they looked at the teeth. All sharks – including megalodons – produce and ultimately lose tens of thousands of teeth throughout their lives.
