Hello everyone. I have always been interested in collecting fossils and stones. I saw this forum randomly while I was searching on Google. I have been collecting fossils and stones for awhile now mostly shells and Coral but I have a small collection of fossils I have kept that are unique to me. It woul be cool to find out more about them.

Hello again, I was doing some surface collecting in Oakland County michigan-- typically the fossils around here are preserved inside of pieces of limestone... I'm no expert on fish or sharks so I'm not sure what exactly this imprint is, but it reminds me of a tooth. Would anybody be able to confirm/deny this? The rock in question is about the size of a dime. Thank you!

Phyllocarid carapace, trilobite, or possibly a brachiopod?
Cassandra Tiensivu posted a topic in Fossil ID
Hello everyone. I’ve been chiseling apart some of my less than fabulous Mississippian Coldwater Shale packstones that I find in South Haven (MI) on Lake Michigan. Typically, I’ll discover various brachiopods, a few gastropods, various bryozoan, some ostracods, and little bits of flora that look like tiny seaweed. However, recently I opened up a packstone with a very different fossil inside. I have nothing else like it in my collection. A few folks I know have speculated the things I mentioned in the title of this post. The second picture is... I guess I would call it a cast? The third picture is the interior of the shell of whatever this creature was.

30 years ago I was in 5th grade and used to hang out nearly every summer day at the back of our property in Van Buren County, field was nearly 60 acres. We would build forts and play in the creek that came off of the Paw Paw River. One day while we were in this deep depression in the ground that the creek went through we found a small black shark tooth. That summer we dug and dug and were able to find about 50 teeth. This week being Spring Break I told my small children maybe we should go look for shark teeth and told them what I did as a young lad. We went back to the old spot I remembered finding them but the deep depression had now caved in. We dug and sorted but didn’t find any more. I am not finding much about shark teeth in Michigan. I have read another post about Port Huron and the people saying they were planted because it was at some commercial gem mine for kids, I’m like oh maybe my parents did too, but after all these years and literally being in the middle of the forest way away from any road, house, etc. I am not buying this. They also told me that they didn’t even know where we dug at, only that we played at the creek. My parents were the type that said “go play as long as you don’t go near the river” we did what we wanted. so that brings me here. Anyone ever found legit shark teeth in Michigan or do I have to call my parents liars after 30 years? I have attached a photo of what we found.

I have some exciting news, thanks to the help of @TqB, who suggested that this tabulate coral I found in southwest Michigan glacial drift a few days ago is much more interesting and unusual than I could have imagined! After thinking about and dismissing a number of favositid possibilities, we realized that this is a cerioid syringoporid. Tarquin suggested that, due to the appearance of domed and/or infundibuliform tabulae inside the transverse and longitudinal sections, along with a few apparent mural pores and a possible syrinx (mural pore tunnel) structure, this might be a roemeriid. This is exciting because, besides a documentation from the Devonian Canadian Arctic on Fossilworks, this family has not been found before on the American continent, certainly not in the U.S. I emailed photos to the tabulate coral specialist Dr. Mikolaj Zapalski, who confirmed Tarquin's diagnosis! Here's his reply this morning: I think that your diagnosis is correct - it is a roemeriid. . . . as far as I can tell, it resembles Roemeripora - but the corallites are much larger than any Roemeripora I have seen. On the other hand I have experience only with some Polish and Russian taxa, so these species may be different. An isolated specimen may not be very helpful, but if further specimens are found, this could be potentially interesting for research. Mikołaj K. Zapalski Ph. D., D. Sc., FLS University of Warsaw, Faculty of Geology So, it looks as though this could be the first known discovery of a roemeriid, possibly a new species of Roemeripora, from the U.S.! Here are photos! I'm sending the specimen to Tarquin in hopes that he can prep it a little better or notice more details that I've missed. Best!

Hello, everyone, I could use some help with this odd little tabulate coral I found yesterday in an old gravel pit in southwest Michigan. I can't guess at a formation or age since it's glacial debris, but the things I find range from possible Ordovician (rarely) all the way to lower Mississippian. I think it must be either Devonian or lower Carboniferous. When I first picked it up, I thought it was just another type of Favosites, given the corallite shapes and what turned out to be large mural pores (towards the left) when enlarged: (EDIT: TqB has suggested parasite traces for these holes I was calling 'mural pores!') But on the other end, the corallites are showing what I thought were curved, incomplete tabulae like Michelinia, but found out after talking with @TqB that they may be funnel-shaped. I forgot to include a size scale, but the corallite diameters range from about 2 mm to just under 4 mm. We're having trouble coming up with cerioid infundibuliform tabulate corals that might be possible for Michigan, and Tarquin suggested that the coral experts here might have some ideas. Many thanks! Lisa

Got a big trilobite as a gift- what kind is it? Is it a fake, or real?
jacquibuddha posted a topic in Fossil ID
Hello! First time posting so I'm sorry if the formatting is wrong...anyways, I recieved this big trilobite as a gift from a shop here in Michigan. I'm afraid I don't have any other information, other than it was what I think is cheap for a fossil? Anyways, here's a few pics of this sucker. Thanks!!!

I have more photos but limited to only 3.95 MB. Egg?

Hello all, I'm not even sure if this is a fossil to begin with, as I'm an amateur fossil hunter. I found this piece in a rock shop called 'Prospector's Paradise', near the center of the Keweenaw Peninsula in Michigan. After talking to the shop owner, it sounds like it could have been found in the Northern part of the Keweenaw. It is possible that he did not find the piece himself, and could come from a different location. I apologize in advance, because it is not much to go on, and it's not a big deal if it can't be solved. The reason I thought it might be a fossil is because one side is smooth and rounded (like a ball-joint that might connect the humerus to the scapula), and because the parts that have been chipped off show a spongey interior (like a medullary cavity). It's possible that it's just a strangely shaped rock, but it would be exciting if it were some sort of fossil. Any help or suggestions would be much appreciated!

Petoskey Stones, Hexagonaria coral, from Devonian in Michigan
traveltip1 posted a topic in Fossil Hunting Trips
These are so-called Petoskey Stones, as I found them along Lake Michigan shoreline. These Devonian age Hexagonaria coral pieces should polish finely.
-
Here are some finds from a late August to early September long loop road trip, fossil hunting through Ohio, Michigan, Wisconsin, Indiana and Kentucky. I'll appreciate detailed specimen identification help. First photo shows brachiopods & a trilobite from the Devonian Silica Shale Formation near Sylvania, northwestern Ohio.

We found the following in Harbor Springs, MI in July. Initially thought it might be petosky, but it’s a lot lighter in color and smaller markings. Thanks in advance!

I found this pretty little chain coral in southwest Michigan glacial drift a couple of days ago. I'm interested in whether it's possible to narrow the ID down between a Halysites species or another genus, like Quepora. My simplistic understanding is that coenenchymal tubules would indicate a Halysites species, so that's what I've been focusing on, although I know there are many other indicators, like size and shape of corallites. size of ranks, shape of luminae, structure of longitudinal tabulae, etc. This piece is probably too silicified to tell without thin sections, anyway, but I thought I'd throw the pics up, in case there's a coral person here who can help me interpret any diagnostic features they see. (The tape measure I tried to hold up in the last photo is cm) Many thanks!

I went up to the UP this week doing mostly sightseeing with my friends. They were aware of my predilection for rockhounding so we often made stops to areas that might bear good fossils/agates. In particular I knew there were some 'lagerstatten' in the Stonington Peninsula region of the UP. The most important formation I know of is the 'Big Hill formation' (correct me if I'm wrong). Some links about it here: https://www.researchgate.net/publication/308005515_A_new_Lagerstatte_from_the_Late_Ordovician_Big_Hill_Formation_Upper_Peninsula_Michigan https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6325806/ Now, I didn't have enough time to bother my friends into finding these exposures (and as far as I know, rock collecting in a national forest is not allowed)... However, while we were driving south on County Road 513 T on the west side of the Stonington Peninsula, headed for the lighthouse, I spied a small hillcut on the east side of the road. The hillcut was directly across from a large cemetery-- we pulled over and I had a quick look at some of the rocks there. The hillcut itself was about 20 feet tall, and maybe 600 feet long. I could see near the top of the cut a few feet of limestone bedding planes jutting out from the escarpment. Weathering had amassed a slopped pile of clay and fossils that nearly filled the ditch at the base of the hillcut. On the surface, I saw many brachiopods (different kinds of Platystrophia, possibly?) some of whom were larger than 2 inches across. I also found some small bryozoan colonies and possibly pieces of isotelus gigas molts. The pieces were too small to tell, I am unsure if this particular roadcut could yield anything fully articulated. The rock was very weak and almost clay like. Does anyone know about this roadcut? What formations might be there? I took a few small samples with me but I didn't want to start excavating, obviously. If anyone is interested I could post some pictures of what I picked up, or I could send more detailed directions. Best, Foss

Hello everyone, I hope I find you well in these trying times. I live near Lake Michigan and sometimes I find fossils with my family in the lake. I used to have a fossil kit as a kid and am a life-long lover of all things science. I tried to change my profile picture but an error just kept popping up saying I needed to be signed in (which I already was). Maybe I'll try it in Chrome but for now I'll look like a newb who just doesn't know how. Feel free to introduce yourself and to talk to me on the threads, I'd love to meet you guys. Anyway, Thanks for reading. -MP

Hey everyone, New user here, very minor experience with fossils. I was curious if anyone would be interested in possibly identifying some specimens from Lake Michigan, from North Shore Beach in Ferrysburg, Michigan. It's on the West Coast of Michigan, but it would be the Eastern side of the Lake. Hope that isn't too confusing and I hope that I find you all well during these trying times. I have a couple more as well, if it's cool. Thanks for reading. Here are my humble hypotheses: 1: Some sort of Petoskey/Charlevoix stone or similar perhaps. 2: Coral? 3? 4? 5? 6? 7/8: Arrowhead shards or shards from producing an arrowhead? 9? 10? 11? 12/13: Horn Coral with a zebra mussel shell inside it?

Greetings! Each summer I visit a small, secluded town in the Northern lower peninsula of Michigan. This beach in particular is just loaded with fossilized corals and shells, and I always come home with some beautiful finds. The area is known for horn corals, petoskey stones, and a related coral fossil known as the Charlevoix stone. Take a look! *Note: the last jpeg is two pictures of the same stone.*

For the purpose of this discussion I will refer to my find as an egg. Even though it may not be. I found this “egg” at a quarry in Southeast Michigan. I have done as much research as google will allow and still am not confident on its identity. On a side note I found another fossil in the same area that I am pretty sure is a type of brachiopod. Not sure if that would help with the identity of my “egg”.

I was cleaning out my desk drawer here at work and I found this. i forgot i had it. anything worth while? found it on a construction site, in Zilwaukee, MI. if you need more photos or close ups, i'll try, this was the best my phone could do.

Hi, My name is Dick41. That does not mean I am 41 year old, but that I was born in 1941. I started collecting rocks and fossils as a boy in Michigan, but have since moved to Colorado where I enjoy getting out and searching for fossils here and in Eastern Utah. I am no expert, but try to identify ones that I collect, and would like to learn more from people in this forum.

Hi everyone. The other day I found this interesting impression in a rock. When I first saw it, I noticed that it looked similar to the sutures inside a cephalopod shell, but I thought it may have been wishful thinking and was probably something else. I took it home and asked on Reddit, and another user also said that they believed it was probably a nautiloid shell. So, I'm coming here for final verification. Is this a nautiloid shell? The fossil was found in northwest Michigan, along Lake Michigan. Thanks in advance!

Hello! I recently went to Grand Ledge, Michigan. This area is part of the Carboniferous, and more specifically the Pennsylvanian period. I found this fossil that appears to be scales. It’s not an imprint either, the scales are elevated. In the surrounding rock there are cordiate fossils and some kind of clam, I found ferns in the area as well. I believe that it was a swamp land way back when these were all alive. An ID on what kind of plant or maybe even fish scales would be awesome! Thank you!

I found these pieces over past year and half and have just gotten around to IDing them. I can’t find anything on the internet or my book on what these are. They are from the Mississippian as I’m from west Michigan. It seems they attach to things as oneI found on a horn coral. One in the picture seems to have shell on the bottom as well. An ID would be awesome because these have been a headache for me! Thank you!

This weekend, I have to drive up to Michigan to finish moving out of my apartment since I graduated, so I thought I would hit up a couple spots along the way. I'll hopefully have plenty of pictures to post here, but my fossil-filled week began earlier than expected so I'll start with that. I couldn't sleep much yesterday and ended up getting up way too early, so I figured I would go check out a Middle Devonian spot (Milwaukee Formation) in SE Wisconsin. I think this spot is pretty well known, so I wasn't expecting to find much. The fauna is pretty similar to what I find in the Silica Shale in Ohio but not as well preserved, so I didn't collect that much as I will be hunting the Silica Shale this weekend. The location is quite scenic, and I spent a lot of my time hiking the trails. Along the trails are a few outcrops, including one that appeared to only have been recently exposed from a tree falling. Unfortunately, most were poorly fossiliferous at best. It seemed like a lot of fossils were concentrated in what are perhaps storm deposits, but these were in the middle of massive dolomite beds and were not worth the effort. I only found one outcrop that was really worth exploring. I think only surface collecting is allowed, not that I would want to bust out a sledge next to hikers and fishermen anyways. The best collecting seemed to be from the more fossiliferous Lindwurm member. The underlying Berthelet is much more thickly bedded and formed a natural ledge for the Lindwurm to collapse onto.

Hello fossil experts! I have a background in geosciences but know very little about fossils. I found the below fossils along the Rouge River near Detroit (Michigan). Doing some quick research, I think these are from the Mucrospirifer order, probably of the Thedfordensis species. Do you agree? (longest is about 1.5 inch / 4 cm) The thing I'm most puzzled about is from what strata they are from. The interweb tells me these Mucrospirifer here are mostly from the Middle Devonian (Antrim shale, Traverse Group), while the location where I found these (as well as all of the upstream terrain) has younger bedrock, from the early Carboniferous/Mississippian (Coldwater Shale). This Coldwater Shale is a pretty thick deposit so a river/glacier can not puncture it easily. I used the Bedrock Geology map from www.esrs.wmich.edu/mgs/webmgs/migis.html Thank you very much for your insight! Jazz
