Hello Everyone! I just wanted to say "Hello" to you all and I am excited to learn from all of you. I found my way here after I watched Rob from the YouTube Channel, "Michigan Rocks". I hope to educated myself on the fossils around the Great Lakes as well as new places for my family and myself to explore.

Found this maybe ostrocod and this maybe placoderm “tooth” plate in the Waukesha formation - Devonian. Acid prepping it atm. What is it?

Found a couple neat things in some bags of rocks from Home Depot
LeapingLaelaps posted a topic in Fossil ID
Hello! I got a few bags of rocks from Home Depot the other week to use for a project, and when I was washing them off I found a couple neat things. Unfortunately the bags were thrown away and the garbage was picked up yesterday so I can't check the bags for the quarry locations, but the bags were purchased in Wisconsin so I would reckon the rocks are from either Wisconsin, Minnesota or Illinois. Here are both next to a tape measure. I'm pretty sure the left one is some kind of brachiopod but I have no idea what the striped one is or if it's even a fossil: And a few different angles of the striped one: Sorry for the obnoxious shadow in front, I was using my flash because it was too dark in the house and since I was so close to the fossil my camera left a shadow.

My son found, what looks to us to be, a backbone in the rock, in the shallow water of a beach in Door County, WI. The first picture is the fossil in question, the others are other things we found interesting but less convinced they are fossils. I would estimate it to be about 15 to 18 inches in length. Any idea what it could be? Thanks in advance for your time.

I’m not sure if this is fossilized or not, but I was hoping I might be able to find more info on it here!
-
Newer to fossils. Been searching the same location for awhile now and it's the first time coming across one like this. Just seems so interesting to me. Maybe it's just a rock? Idk any help is appreciated.

Need help confirming what I found. This speciman was found in Milwaukee, WI. I found it in some loose landscape rock around the building I work in. Unfortunately I don't have a ruler on me right now but it's about 2 inches long and 3/4 inches wide. Originally I thought it was agate but someone in my rock group on Facebook says it looks to be silicified stromatoporoid. After doing a Google search I came across stromatolites also. So I'm not sure which one it could be. It's a beautiful specimen. What looks to be quartz on the bottom and what I originally thought was agate surrounding it. Any ideas of what this could be? Thanks a ton! (Sorry about holding the speciman. These pics were taken when I found it and I have the specimen at home and not on me right now. I tried to crop out my fingers) Pics: side view, end view and top view

Hey all! I'm new to this site, but I've been interested in fossils all my life. I kind of joined this forum on a whim since I've been doing a lot of internet surfing recently. I'm on a quest of sorts to try and find any trilobite remains in my state, (I live in Green Bay, WI) but I'm not having much luck. I've been all over the internet looking for any known collecting sites in Wisconsin. I'm well aware of places like Fossil Park in Sylvania, Ohio, and I'd absolutely love to have a chance to visit Penn-Dixie in northwest New York, but I don't really have the time, so I've been trying to find somewhere in Wisconsin that I can drive out to for a day or two. However, I haven't had much success. I've heard of some more well-known sites, but I can't really figure out if any of them are open to collecting of any kind, and I'd rather know beforehand. I've used this website (Click here) to try and narrow my search, but I can't really find much info on any of these places or what kind of fossils they may have. One of the most promising leads I currently have is Olde Stone Quarry in Door County. It's an old limestone quarry, but I'd still like to know if there's somewhere more promising for looking for trilos. Any opinions? (Summary): Anybody know of any specific places in Wisconsin where one can search for trilobites? I can't find much info on collecting. Any leads are appreciated

7th International Conference on Trilobites & Their Relatives
connorp posted a topic in General Fossil Discussion
Registration has opened from the 7th International Conference on Trilobites & Their Relatives in Cincinnati, Ohio. This is a four day conference (including a mid-conference field trip), plus pre- and post-conference field trips. The pre-conference field trip is to the Upper Cambrian of Wisconsin, and the post-conference field trip is to the Ordovician-Devonian of New York. The latter looks like it will visit some very enticing spots (unfortunately it is quite expensive!). The mid-conference field trip will visit several classic Cincinnatian sites, including possibly the famous Mt. Orab Trilobite Farm. I registered for the conference and hopefully can spend a few extra days collecting the Cincinnatian. Hopefully I'll see some of you there! https://www.cincymuseum.org/7th-international-conference-on-trilobites-and-their-relatives/-

Posting this for someone on Facebook - found near the Mississippi River, SW Wisconsin. Lycopod root?

Hello! I have been lurking on this Forum for a while because I was very busy lately and still is! I found few fossils and I thought it might be trilobits- pieces of trilobite and also something else that I thought it seems 'fishy' and somewhat resemble a fish spine. These fossils are not found in situ but the bedrocks are Silurian. If they are trilobites, it would be my first time found one! I found this on the beach of Lake Erie, just east of Toledo, Ohio two weeks ago. Approximately half centimeter. Yesterday, I found this fossil on the beach of Lake Michigan in Kenosha, Wisconsin - just north of Illinois state line. It looks like a cross section of a trilobite to me. Approximately a centimeter and half wide. Unknown and resembles a fish spine, approximately two centimeters long. Thank you in advance and I am looking forward to seeing the responses!

I recently found a piece of petrified wood that has amber bubbling on the top and embedded into the piece. I found it in a region where people have told me there is no petrified wood. I know that it is. I have seen quite a few pieces of petrified wood from Arkansas and a few with amber embedded. This was found in Wisconsin in the Mississippi river valley. Any thoughts?

Hey all! I took my little brother out fossil hunting on the lakeshore, I myself am no expert but it's been a lot of fun- we found a number of crinoid and brachiopod fossils and some cool rocks besides. Theres a couple that stumped us though, I've been googling references but nothing looks similar to me. It looked to me like some kind of coral, the second one might just be a rock with some holes in it, but they appear in a fairly regular pattern that intrigued me. Any input is appreciated!

New to this group and new to fossil hunting. 2 weeks ago was in Florida with the family and found 62 shark teeth along the beach and started to research what they where. Stumbled upon this website and was hooked reading and looking at what all is out there. Hope to learn a lot going forward!

Found this near a lake in polk county Wisconsin. There seems to be a somewhat unusual pattern on it. Can anybody identify this? I can get more photos and dimensions if needed. Thanks a bunch!

Hello everyone! I recently purchased two fossils, they were both sold to me as Ordovician the crinoid being from Wisconsin and the brachiopod from Illinois. @connorp has told me in a different thread that the dolomites of the region also preserve Silurian fossils and that these look much more like that. Doing a quick Google search I did find something that looks very similar to the crinoid I have, but I don't know enough about these animals or the area they come from to be certain of the ID. Here is the crinoid in question: To me this calyx looked quite similar to that of siphonocrinus both in the gener shape and the plates covering it's surface. Here are some pictures I found online with the region that looked especially similar circled in red: Along with it I also bought this Pentamerid brachiopod which could very likely also be Silurian. Could it belong to the genus Pentamerus?

I am new to this forum and have very little knowledge of fossils. I would like to know if this rock that I found several years ago in northwest Wisconsin is a fossil or just an interesting rock. Thank you.
-
A while back I found this fossil in Wisconsin, unfortunately I don't remember where exactly I was when I found it. So far I have been unable to easily identify it. It is about 2 inches across, and about an inch tall. I can post more pictures if needed.

My collection of some really cool fossils on the land most of the fossils I have in my collection are bought so it’s always nice to find something actually in the field. Now my main goal with this post is to try to identify the trilobite I found today although it only has the head piece, it clearly shows the eye and part of the gabella. The horn coral which are the sort of conical fossils should help identify the age of the rocks. if anyone else can give an ID on the rest of the fossils that would help thanks. By the way these were all found in Dane County, Wisconsin. (PS) I have no clue what the fossil is with the weird holes.

A couple more Platteville Formation Grant Co. Wisconsin Trilobite and some others
SteveRogers posted a topic in Fossil ID
Hello, I had some time to look at a few more of the rocks from my collection trip into Wisconsin Platteville Grant County 1,2,3 First is a flat creek rock I gave a scrub and I think it has a trilobite cephalon. 4,5,Is a rock that appears to have a trilobites or it coiled be a broken bivalve? It's in a flakey rock so I haven't picked at it much. I included a side picture of the sediments. 6,7 I am pretty sure these are Chondrites? Or something similar? There are also some other bits in it 8 is a bit of hash plate but it has what I assume must be pyrite bits that are a bit flashy golden - hard to see in the pic but there ar little bit popping out and reflective - I figured I before I show my daughter I figured I should confirm they are pyrite or something similar - and not what she will immediately think it is! Thanks and I hope you all have a wonderful weekend! I'll keep sorting and seeing what I got and maybe walk a creek or two for fun

Found all of these beautiful fossils on Lake Michigan, specifically Pleasant Prairie, Wisconsin on Prairie Shores Beach. Would not mind if anyone could give me an ID

Hello! After losing 2020, and then winter, I was finally able to get out and look around in my new area, NE Iowa and near Grant County, Wisconsin. I walked down a few rivers in the Ordovician areas, Platteville Formation, Grant County, and picked up what I think might be a Trilobite? Based on the Various publications of the region, it may be Sceptaspis lincolnensi, but this is really my first Trilobite I have found (in many years of walking along looking at rocks) I haven't cleaned off any of the matrix, just a nice scrub. I also found this hash plate nearby, I liked the Gastropod? In the center and noticed and when I looked it may have a similar trilobite? Thanks, appreciate your help!

With the nicer weather last week, I was able to make two brief trips to kick of the year. There still ended up being a lot of snow on the ground, but it was manageable. My first trip was to one of my favorite sites, a roadcut in the Pennsylvanian LaSalle Limestone in Illinois. Lots of the usual stuff was found, but the two trip makers were a small Peripristis shark tooth and a Linoproductus mass mortality plate. Here's the tooth. I think it will clean up nicely. And here are the Linoproductus. There's around 50 individuals present, and they are all quite small compared to most Linoproductus specimens I find at this site. This is probably the best brach plate I've found here. Here's a random shot I took of the headwall. Most of the common brachiopod species at this site are visible. A few days later I had a couple hours free in the morning and checked out some new Ordovician spots in southern Wisconsin. Here's a neat roadcut I drove past, showing the contact between the Ancell and Sinnipee Groups. The lower unit is the St. Peter Sandstone and the upper unit is the Pecatonica Member of the Platteville Formation. The Glenwood Shale is the narrow shale unit between the two. The site I ended up hunting was in the Grand Detour Member of the Platteville. In this area it's mostly dolomite, and most fossils are internal molds. The preservation is thus not great, but splitting rock can yield nice mollusks on occasion. Here's a typical example of the molluscan hash. This large Ctenodonta was a nice treat. It's about 6cm at the widest dimension. The trip maker was a coiled nautiloid, the first I've found. I am not sure on the ID. It measures about 2cm in diameter.

Hi I broke open a rock in southwest Wisconsin, and I found this collection of brachiopods. Can anyone try to tell me what genus they are? Each of them are around 2 cm long.
