Petoskey Stone
These stones are distinguishable based upon their unique exoskeleton structures. The actual stones are made up of tightly packed, six-sided corallites, which are the skeletons of the once-living coral polyps, Favosite. The center of each polyp was the mouth and contained tentacles that reached out for food. The hexagon shape of each cell and thin lines radiating out from the dark “eye” in the center are distinguishing features unique to this fossil. Keep an eye out for the rare “Pink Pets” Petoskey Stones. The pink hue is a result of the iron that permeated the coral as it is calcified.
