The Petoskey Stone is Michigan’s official state stone and can be found on northern Michigan beaches. This fossilized coral is known scientifically as Hexagonaria percarinata.
These stones are remnants of ancient coral reefs that thrived approximately 350 million years ago during the Devonian period, when the region was covered by a warm, shallow sea. (Wikipedia)
The distinctive hexagonal patterns seen on Petoskey Stones are the fossilized remains of coral polyps, each hexagon representing an individual polyp that once lived in the colony. Over time, geological processes transformed these coral structures into the unique stones we find today.
