There are many kinds of fossilized shark teeth.

Sand tiger shark teeth.

Mako shark teeth.

Bull shark teeth.

A couple of days ago we went to Cumberland Island and that’s where we found fossilized shark teeth which are black.  Fossilized shark teeth turn black because of the minerals they have in them.

There’s so many teeth at Cumberland Island, I found 53 teeth in all.

We used sifters to find them.

The first day was really hot so we came back later with umbrellas and more water.

Some sharks can lose up to 35,000 teeth in a lifetime!  The most common kind of shark teeth people find are from the Cenozoic which was about 65 million years ago.  The largest shark teeth of any kind is from the Megalodon shark.

This is a Megalodon compared to a T-Rex.

Their teeth can get up to 7 inches tall or more, but we didn’t find any of these.  This picture is from the internet.

Cumberland Island was a lot of fun but digging for sharks teeth was the best part.
