I drive 8 hours with a friend to a location he remembers from his childhood as yielding a lot. Oh boy it did. 100% worth the drive. Lake Huron, among the agates, pyrite, yooperlite, has some extraordinary Devonian fossils. All fossils were collected from the beach of his family’s property except for the fenestelid bryozoan, which was found at a gas station on the way there. please enjoy this collection of gastropods, petoskey stones, various tabulate corals, crinoids, stromatoporoids, bivalves, Brachiopods, tenteculites, horn corals, an unidentified agatized fossil in jasper matrix, and a pudding stone I felt like showing off too. Thanks! I highly recommend the area.

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, grinding off their rough edges and depositing them in the northwestern (and some in the northeastern) portion of Michigan's lower peninsula. In those same areas of Michigan, complete fossilized coral colony heads can be found in the source rocks for the Petoskey stones. Petoskey stones are found in the Gravel Point Formation of the Traverse Group. They are fragments of a coral reef that was originally deposited during the Devonian period.[1] 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. It is sometimes made into decorative objects. Other forms of fossilized coral are also found in the same location. In 1965, it was named the state stone of Michigan.

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 hand polished this piece and had it set in a pendant by a local jeweler. Another form of fossilized corals are also found in the same location,Charlevoix stones.Charlevoix stones are Favosites an extinct kind of tabulate coral. While hunting for Petoskey stones I found this Actinostroma. Apparently these stromatoporoids are common but I thought that this one was a well preserved specimen.

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