Being a fossil it is naturally soft and can have many imperfections such as cracks and other mineral deposits mixed in. A Petoskey stone found on the beach can be smooth, and the fossil can be very distinct. This is not only because of the wave action of the water, but because the stones have been tumbled and rolled against other stones and smoothed by the sand. The pitted, rougher stones are usually found on shore or inland. This information is provided courtesy of its author Barbara Fochtman.
