Lise found the first blastoid of the year at Arkona, during last weeks spectacular warm spell. She also found the first Petoskey stone, though there was very little of Lake Huron’s shoreline free of snow and ice. I, however, found a stromatoporoid. An interesting piece, from a chunk of armour stone, quarried from somewhere or other. A spectacular ice nugget was also found.

The rock on the right is a Petoskey stone but the rock on the left I am uncertain about. I found it in Alcona County, Michigan and it might be some sort of large celled Hexagonaria but I’m not sure. If anyone could help me identify it that would be great.

Went to the Bone Valley Club Show Saturday, I had been watching YouTube about this stone, I bought this one for 12.00, I knew I would never go to Michigan but I have followed Warren Petoski who is native american and from Michigan. The city and I believe this stone is named after his family who have been this this are many generations. A Petoskey stone is a rock and a fossil, often pebble-shaped, that is composed of a fossilized rugose coral, Hexagonaria percarinata.[1] Such stones were formed as a result of glaciation, in which sheets of ice plucked stones from the bedrock, grind

Hey everyone! I was exploring a private beach next to a graveyard in Petoskey, Mi. I mostly found regular Petoskey stones but I ran across afew things I found unusual. [1st & 2nd picture] I'm almost positive this is a shark tooth. [4th picture] the dark stone I'm also unsure of. Let me know what you guys think! Thank you so much. James Carden Here's another look at the same stone dry: Larger picture of everything I found:

Hello, all. New to the form and first post. I wanted to share what my daughter found among the wood chips in our neighborhood playground and ask if there's a way to "clean" it up (remove the rocks, etc.) without damage. I believe it is a petoskey stone and I'm not interested in polishing it, as I can purchase polished stones pretty much anywhere here in Michigan. Thanks!

These are a few finds from our last trip to the beach. But I've never seen or heard of a pink petoskey?

HI there, I recently found a Petoskey Stone among others on the same tiny (12 foot) beach in Mid/Upper Michigan, as I have for years in the same location. Only...this one's different. I can't seem to polish it down entirely by hand OR with a dremel. It has a lot of beveled structure still compared to others I've seen, and it just feels HARD. There also seem to be tiny crystal bits in some places. Can Pestoskey Stones (limestone as I understand it) harden into Travertine or Marble and retain their distinct pattern and shape?

It is not rounded but weathered. One and 1/2 inch.

Last summer my wife and I took a side trip on our way to Mackinac Island to hunt for Petoskey stones along the shores of Lake Michigan at Little Traverse Bay.Petoskey stones are a fossilized rugose coral, Hexagonaria percarinata, found in the Gravel Point Formation of the Traverse Group from the Devonian era.Glaciers deposited chunks of this coral that were subsequently rounded by wave action. When dry, the stone resembles ordinary limestone but when wet or polished using lapidary techniques, the distinctive mottled pattern of the six-sided coral fossils emerges.

I found this while looking for petoskey stones near Traverse city, and I am curious about what it might be.
