2.9" Polished Petoskey Stone (Fossil Coral) Slab - Michigan

This is a beautiful slab of fossil coral (Hexagonaria percarinata) from Michigan. It has been polished to a glossy finish on one side, while the other side has only been polished to a matte finish. The polish really allows for the detailed structures of the coral head to be seen.

An acrylic display stand will accompany your purpose.

Known locally as "petoskey stones" this fossil coral can be found along the beaches of Lake Michigan, Lake Huron, as well as in rock quarries from Alpena to Traverse City, Michigan. The species is Hexagonaria percarinata, a type of rugose coral that lived during the Middle Devonian period, about 350 million years ago. Petoskey stones are the state stone of Michigan.
