This is Michigan’s Official State Stone, the Petoskey, Hexagonaria percarinata.(2667 views as of 12/18;2014) This particular stone was polished and then I photographed it with my Canon EOS 6D camera with a Sigma 70mm macro lens. Petoskey stones were colonial corals that lived in the Devonian Period – 355 to 415 million years ago.

Bob Kelch is a retired pediatrician and health care administrator who now has the time he wants to devote to his passion, photography. He lives near the Lake Michigan shore in South Haven, Michigan.

    Very nice! I looked for one of those last summer but could not find any. Amazing detail! Thanks for sharing!

  • Thank you. We find several Petoskey stones each year, but they are not common on our beach in South Haven. They are much more commonly found further north along the Lake Michigan shore.

    Isn’t it amazing, to hold something in your hand so ancient?? Makes you realize, time and space are not “outside” us ~ rather, we’re a note in the symphony. Also, makes a fascinting photo! :-)) Congratulations on your Feature in Exploring Mid-America!

  • Thank you very much for your interesting and nice comments. I love to look for and collect fossil stones and them I sometimes make jewelry out of them.
