I have been doing some research in preparation for my demonstration at this weekends Rock, Fossil and Mineral Show at the Ingham County Fairgrounds in Michigan. (By-the-way, if you are in the area, come on by and check out the show!) In my searching, I came upon a booklet by the University of Michigan Museum of Paleontology, dated June 1970. Below is the link. deepblue.lib.umich.edu/bitstream/handle/2027.42/48447/ID296.pdf?sequence=2According to this booklet, we can ONLY call Hexagonaria Percarinata "true" Petoskey Stone! The other EIGHT varieties of Hexagonaria (all listed on page 81 of the booket) are NOT true Petoskey. The true Petoskey is found in the Little Traverse Bay area (near Petoskey, Mi) and nowhere else. So......if you found some coral fossil in Alpena for example, it is most likely Hexagonaria ANNA, and NOT Petoskey! I have a complete colony of the Hexagonaria Anna that I purchased from another dealer. They said it was found years ago in Rockport Quarry. When I compared it to the images in the UofM booklet, it was a perfect match! Besides, being found in Rockport Quarry is the clincher! So, after looking at the UofM booklet, and the information and images within, what do you think you REALLY have? True Petoskey (Hexagonaria percarinata) or some other form of Hexagonaria? P.S. I also read in a fossil book by the Audubon Society, that TRUE Petoskey is NOT Hexagonaria, but instead PRISMATOPHYLLUM. See the below information: According to the NATIONAL AUDUBOM SOCIETY FIELD GUIDE TO NORTH AMERICAN FOSSILS, the “true Petoskey stone” is called: “Prismatophyllum” “Prismatophyllum is the “Petoskey stone” of northern Michigan, and the official stone of that state. Petoskey stones are pieces of Prismatophyllum colonies that have been broken off and subsequently rounded by streams. They are often brilliantly colored and can be polished to show the structure of the corallites in 3 dimensions. Hexagonaria is also called “Petoskey stone” in some references. Hexagonaria is a similar genus that is found in the Devonian of western North America, but does occur as far east as Michigan. Hexagonaria tends to have thicker walls and septa."*Above quote taken from page 363 of the 1995 edition of the aforementioned book. Also, many people misidentify ACROCYATHUS as Petoskey stone. It has little "bumps or ridges" in the center of the cells. All of this is making me take a second look at all of my Petoskey stone collection. Yet again, unless people do in-depth research, most people won't know the difference. Polished - it all looks nice!

How did petoskies get originally named?
Who is the authority that made that name?
Can anybody look at the stones and using the identification key tell us where they are from? Meaning, I have have "true" petoskies can I key it out and say yep, it's from "petoskies bay" and show my client the character that proves it?
This seems like splitting hairs too me.

Here is how Petoskey stone got it's name...... The name Petoskey Stone likely came about because it was found and sold as a souvenir from the Petoskey [city] area. [The southern shore of the LITTLE Traverse Bay]. The name Petoskey appears to have originated late in the 18th century. Its roots stem from an Ottawa Indian legend. According to legend, a descendant of French nobility named Antoine Carre visited what is now the Petoskey [city] area and became a fur trader with the John Jacob Astor Fur Company. In time, he met and married an Ottawa (or Odawa) Indian princess. Carre became known to the Indians as Neaatooshing. He was eventually adopted by the tribe and made chief. In the spring of 1787, after having spent the winter near what is now Chicago, Chief Neaatooshing and his royal family started home. On the way, the party camped on the banks of the Kalamazoo River. During the night, a son was born to the Chief. As the sun rose, its rays fell on the face of the new baby. Seeing the sunshine on his son's face, the Chief proclaimed, " His name shall be Petosegay. He shall become an important person. " The translation of the name is " rising sun," " rays of dawn," or " sunbeams of promise". In the summer of 1873, just a few years before the death of Petosegay, a city came into being on his land along the bay at Bear Creek. The site was a field overgrown with June grass. Only a few nondescript buildings existed. The population was no more than 50 or 60. The city was named Petoskey, an English adaptation of Petosegay. Thus they honored someone who gave his land, name, and the heritage of " sunbeams of promise". For the rest of the information go to: geo.msu.edu/extra/geogmich/petoskystone.htmlThere are those who are currently trying to make the official definition of what a Petoskey stone is as.....any Hexagonaria rugose colony fossil coral that is found in the Michigan Basin - in the Traverse Group formation can be called a Petoskey Stone. This would be a problem, because there are nine different Hexagonaria rugose colony corals in Michigan, and several of them can be in the Traverse Group formation at the same time. Not ALL of them look like Petoskey stone! The debate will go on. It just ticks me off when people call Indonesian Fossil Coral and AFRICAN Hexagonaria Petoskey stone! Neither is even from the USA let alone MICHIGAN!

I also read in a fossil book by the Audubon Society, that TRUE Petoskey is NOT Hexagonaria, but instead PRISMATOPHYLLUM. See the below information: According to the NATIONAL AUDUBOM SOCIETY FIELD GUIDE TO NORTH AMERICAN FOSSILS, the “true Petoskey stone” is called: “Prismatophyllum” “Prismatophyllum is the “Petoskey stone” of northern Michigan, and the official stone of that state. Petoskey stones are pieces of Prismatophyllum colonies that have been broken off and subsequently rounded by streams. They are often brilliantly colored and can be polished to show the structure of the corallites in 3 dimensions. Hexagonaria is also called “Petoskey stone” in some references. Hexagonaria is a similar genus that is found in the Devonian of western North America, but does occur as far east as Michigan. Hexagonaria tends to have thicker walls and septa."
There often remains some confusion over the genus Prismatophyllum in relationship to Petoskey stones. Prismatophyllum percarinatum, for example--named in 1939--was an older and now obsolete name for the same coral that today is called true Petoskey Stone, Hexagonaria percarinata (re-named in 1969).
So technically, of course, when in 1965 the Michigan legislature designated Petoskey Stone as the State Stone (signed by Governor George Romney), the extinct Devonian rugose coral they were then referring to was Prismatophyllum percarinatum, which is now known as Hexagonaria percarinata (since 1969)--a species that occurs ONLY in the Gravel Point Formation of the Traverse Group of Michigan in the vicintiy of Petoskey, Michigan.
Then too, earlier designations for today's Hexagonaria percarinata (formally erected as a coral genus in the scientific literature in 1896) were Acervularia profunda and Cyathophyllum davidsoni.
If you want to take it back to the very beginning, the first scientific name applied to what today is called true Petoskey Stone--Hexagonaria percarinata--was in actual fact Acervularia davidsoni (1866).
And just to make matters even murkier, in "the recent past" Hexagonaria percarinata (true Petoskey Stone) was often called Prismatophyllum davidsoni.
The ultimate upshot of all of this is this: By definition, true Petoskey Stone--the extinct Devonian-age colonial rugose coral that the Michigan legislature designated as the State Stone of Michigan in 1965--is now called Hexagonaria percarinata.

Beautiful specimen Larry! Great to see an unrolled example.
Funny about scientific names. When I was in college, profs were always talking about "lumpers" and "splitters". Constant war going on with grad students wanting to discover and thereafter "name" new species. Some scientist fighting this and wanted to consolidate genera while others wanting to split off every little variation. And then another group, the one winning now, wanting to remove narcissistic "people names" and only have scientific names based on specimen appearance or morphology. The constant flux created by all of this simply creates a lot of confusion. My best fossil book was written many years ago and many of the scientific names are now defunct.....Mel

I can find lots of that sort of thing at Rockport, a local abandoned quarry. In that particular quarry, the Alpena hexagonaria (whatever it's called) tends to be black and doesn't grind well. If you grind off the three dimensional pattern, it usually just looks like a black rock. It's fairly easy to find them in the 10-20 pound range though. I did talk to a guy selling jewelry at a craft show who said that he finds his Petoskeys at Rockport. They weren't the awful black stuff, but they didn't look great to me either.

Lol Recently, during the last two or three decades a new concept of taxonomy called cladistics became popular.. They (among other things) ask if a species is allopatric and diagnosible. Is the population discrete and once can say for sure where it was found by simple analysis. I don't like it, but it works for some taxon's. ETA: For instance, humans. How many species would this scheme produce?

YES, ALL HEXAGONARIA ARE PETOSKEY STONES - MICHIGAN'S STATE STONE - NOT JUST ONE SPECIES. I found this online at: www.snobappealjewelry.com/blog/category/petoskey-stone/Petoskey Stones are a group of Happy Hexagonaria and Not just one Species. Legal Terms you need to Know Definitions: A Bill is a Legislative Proposal offered for debate before its enactment. An Act is a Statute, law. or a decision by a Legislative Body. An Enrolled House Bill is the final copy of a bill or joint resolution that has passed both houses of congress in identical form. An Enrolled House Bill is the document that is eventually signed by the Governor. This is important. I have seen online Posts identifying HB 2297 as the bill that made Petoskey Stones the State Stone of Michigan, but Act No. 89, Public Acts of 1965 is the Legal Authority that made the Petoskey Stone Michigan’s Official State Stone. From my archives via an estate sale. This is a rare copy of the Endorsed bill that Gov. Romney signed into Act No. 89 on June 28, 1965 History of Legislation In 1965 a bill was authored by Representatives- Eugene R. Cater-Ludington and Stanley Powell-Ionia (that being HB2297). This bill was to make the PETOSKEY STONE the official State Stone of Michigan. The legislature passed rapidly through to the Governor’s desk. Act No. 89, of Public Acts of 1965 was signed by Governor Romney on June 28, 1965. This Act made the Petoskey Stone Michigan’s Official State Stone. The Act simply states that the PETOSKEY STONE is the Official State Stone of Michigan. There was no mention of one specific species of Hexagonaria being Michigan’s State Stone. In 1965 there were at least 7 recognized species of Hexagonaria. Now there at at least 9 recognized types of Hexagonaria. By making Act No. 89 general in nature, the Act still applies to newly identified species. There have never been any amendments to Act No. 89, according to State Archives. Prior to retirement, I enforced State Laws for 40 years. I have been involved with writing legislation and testifying before a State committee on a couple proposed Bills, helping write one of them. I’m well versed in how the government works, and how Acts and laws are passed. You cannot read into State Legislation what is not there, and this seems to be the case with Act No. 89, PA 1965, where various people; a lot of people; have added information that is not present in the law or Act itself. Some Things About the Author I admit that even though I have hunted thousands of pounds of Petoskey Stones over 50 years or so, and sold thousands of pounds of them, I am still not good enough to identify specific species of them. I can pretty much ID a Hexagonaria percarinata because it’s the most common Petoskey Stone I find, and Hexagonaria anna because it’s very large, but the other Hexagonaria usually stump me. To me, as with most, finding a Petoskey Stone is good enough. An article I co-wrote with Dr. George Robinson in Rocks and Minerals (May/June 2013, Vol 88, No. 3) introduced Pink Petoskey Stones to the world. A pink Petoskey that I found and donated to the A.E. Seaman Mineral Museum is now on display in their Michigan Fossil Case. Some think a Hexgonaria does not become a Petoskey Stone until it has been polished, but commonly the rough waterwashed stones are called Petoskey Stones. The intent of Act 89 was clearly to include the stones people find in random Michigan locations. Some refer to Hexagonaria from other states and localities around the world, as Petoskey Stone. Very simply, the Act NEVER mentions that a particular species of Hexagonaria was the Official State Stone. The bill simply states that the Petoskey Stone is Michigan’s Official State Stone. Most people liked the general nature of Act 89. If you found a Petoskey Stone (Hexagonaria), no matter what species, you still can claim you found an Official State Stone, giving you a happy time feeling. I, as well as most Petoskey Stone Hunters believe that if you find a Michigan fossil of colonial coral with six sides, it’s a Petoskey Stone. This is not really the case, but close enough for me. In the Geology of Michigan (John A. Dorr, Jr., c1970) he states “Colonial coral fragments eroded from these rocks (the ledges and Devonian Age Reefs) often are found along the beaches of lakes in the Lower Peninsula. When polished by the abrasive action of the waves, these are called “Petoskey stones”.” Small patterns do not mean this is a baby Petoskey. It simply means that this is a different species. What species? I do not know. No matter the species, it’s still a Petoskey Stone. Dr. Stumm’s Position The suggestion that Hexagonaria pericarnata be Michigan’s State Stone. was made by Dr. Erwin C. (Win) Stumm in 1969 (4 years after the State Act was signed into law). Dr. Strumm made this distinction based on his extensive knowledge of fossils. He knew that percarinata was the most common Hexagonaria found in Michigan. Dr. Strumm died on April 24, 1969. He was undoubtedly the leading expert in the world on Devonian Invertabrate fossils at that time. A paper published in 1970, after Stumm’s death. You can read his Corals of the Traverse Group of Michigan Part 13 Hexagonaria and see photos of various species. This is a heavy duty scientific paper. In the paper, Stumm writes “Hexagonaria percarinata is the famous Petoskey Stone adopted by the legislature as The State Stone of Michigan”. Could it be that Stumm did not know what the State Act said? It was too late to ask him by the time his paper was published. This was all well and good, that Dr Stumm suggested Hexagonaria percarinata was the state stone, but Dr. Stumm did not have the legal authority to change State Legislation. ONLY a lawmaking body can make changes in already passed State Legislation. Act No. 89 of Public Acts of 1965 was never amended. Off and on people have suggested that the historical and common term of Petoskey Stone be more clearly defined. I do not think it should. Take a look at the photos in his paper. Would you know the difference in species, when you pick up a Petoskey Stone? Act 89 has never been changed, therefore the Petoskey Stone remains Michigan’s Official State Stone designation-NOT Hexagonaria percarinata. People have been told, by so called experts, that what they found was NOT a Petoskey Stone, because it was not a Hexagonaria percarinata. Is Hexagonaria percarinata a Petoskey Stone? Yes it is; but so are many other Hexagonaria species. Just because Stumm stated that Hexagonaria percarinata was his selection as the State Stone, it did not make it so. Shortly after Stumm made his statement, false information started to appear that somehow Hexagonaria percarinata became the Official State Stone. Not the case friends, no change in the law took place. Today, you may read on the web; Petoskey Stone-(Hexagonaria percarinata) this and Petoskey Stone-(Hexagonaria percarinata) that, whenever Michigan’s State Stone is mentioned. The term (Hexagonaria Percarinata) always seems to be in parenthesis, following Petoskey Stone on the web, and in print. I’ve never seen an Official State document that has parenthesis in it. This is a dead giveaway that someone just added this information later. In a legal document. parenthesis are never used. It is impossible to track down when exactly placing (Hexagonaria Percarinata) after Petoskey Stone became common practice, but it did. I really think it is way too late to do anything about the proliferation of mis-information on the web, and many other places, but certainly the facts are the facts. I come from a prior life of Incident Reports, legal docs, Investigations,and facts. (“Just the facts, ma’am.”) If you can convince me I’m incorrect in what I write, feel free to let me know. If someone tells you that Hexagonaria percarinata is the State Stone, You are welcome to show the copy of Act 89, PA 1965 that is posted in this blog. Ask them where in this Michigan Act, it says anything about Hexagonaria percarinata? Some of you may doubt what I have written is true, but the evidence and facts are readily available. Check the facts yourself. It’s unfortunate so many people believe what they read on the Internet without checking the facts.

I've read the post fairly quickly, but tend to agree with the interpretation. The term Petosky stone has no scientific status. Its a common name for a particular organism or group of organisms. The state legislation was giving identity to a type of stone (fossil) that it chose as a symbol of the state. The bottom line is that there are several fossil species that could be legitimately called Petoskys. While we as amateurs might be tempted by familiarity to presume we can identify fossil species, it is usually the case that our enthusiasm exceeds our intelligence or knowledge. He who presumes to always be correct is on risky turf.

sh that's a very interesting post. I, and most everyone I know calls all Hexagonaria "Petoskey Stone". After reading this post and many similar things on the Internet years ago, I figured that most of what I was picking up was not the actual Petoskey Stone, but I also figured that almost no one knew the difference or cared. It's nice to know that all those were actually Petoseky stones. Thank you for such a great post!

Is this the one near Afton? I don't know anything specific but I did read that there are Petoskey Stones found in the Onaway State Park. I have thought about stopping there but haven't. It is about the same latitude as Onaway so depending on how deep the quarry is there may be some there or other fossils as it looks like it is a limestone quarry.
