About Michigan Petoskey Stone
The Michigan Petoskey Stone is a coral fossil dating to the Devonian. Petoskey Stone is a realistic Michigan fossil profile built around weathered colonial coral Hexagonaria polished by Great Lakes waves. In this state, success usually comes from learning glacial till, Devonian limestones, and Lake Superior gravels, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.
“According to TroveRadar, Michigan Petoskey Stone fossils from the Devonian are found across Michigan. TroveRadar's field database catalogs 795+ fossil entries for identification and collection guidance.”
