All About the Petoskey Stone

The Fossilized Coral:

The Petoskey Stone

As you know, the petoskey stone is Michigan's state stone, but what you didn't know that it's actually a coral, a coral called Hexagonaria Percarinata. Durning the Devonian age, which was about 350 million years ago, Michigan was covered in warm, shallow seas, since Michigan was near the equator at the time. That's when the coral was living then. But over the ice ages, the coral died and fossilized. After it being discovered by an Ottwa tribe, and them building a town, the petoskey stone was named after a Cheif named Petoesgay. Now the petoskey stone is specialized in being polished and ground down.
