Does anyone have experience with the Middle Ordovician brachiopod faunas of the upper Mississippi Valley? I came across this odd fragment in rocks from a quarry in south-central Wisconsin. To my knowledge they are known in North America only from the Appalachian Basin (Tennessee, Virginia, West Virginia, Pennsylvania, Quebec, Newfoundland), not the interior basins like the Illinois basin. Has anybody else seen this critter or similar in the Platteville? As far as I am aware, the only species documented from the Platteville that looks anything like this is Megamyonia unicostata, but that h

Last week we took a ride to Lake Michigan to do a short search before the weather turned bad. The previous day had strong winds with large waves and I thought we might find some interesting things. We found plenty of Favosites, Halysites, and Rugose corrals as well as some of the other usual finds. The one unusual find was what I believe to be an internal mold of a Pentamerus oblongus brachiopod. I don't find many brachiopods and as such I'm not 100% sure on my ID. Please confirm or correct. Thanks in advance. Jim

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

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!

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 t

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

*Higher resolution and many more images linked below to Google Drive for a clear view* Fossil: Large limestone rock containing hundreds of marine fossils and with what appears to be a bone roughly 3cm in diameter. As well what appears to be the remains of other bone structures. Location: Found 10 miles from the Mississippi River near Ellsworth, Wisconsin USA (Western Wisconsin) in a low valley area that looks like an ancient river bed. Rock Measurements: Roughly 15cm x 28cm My Understanding of Geology and Paleontology: 2/10 *There are

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 ar -
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

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 com

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 cent

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.

I'm excited to get into fossil collecting, but before I spend money on gear, I'd like to be able to make an informed decision. The fossils I'd be collecting are from the Silurian age Racine Dolomite. I know that Estwing tools are generally considered the best, but other than that, I am completely unsure as to which hammers and chisels would be most appropriate for breaking these apparently very hard rocks, or even how to go about using them. I know a spot on a friend's property (by the Milwaukee River) where there are a bunch of Silurian rocks piled up, so I don't think access will be a huge p

I spotted this thing in a hash plate and I'm wondering what it could be. I'm assuming it's a fragment of something like everything else it is jumbled with, but I don't really recognize it as anything. Found in SW Wisconsin in the platteville formation.

I've got this big hash plate that I collected last year and I somehow didn't notice this thing poking out until now. It looks like an algae to me. Found in SW Wisconsin in the platteville formation.

I graduated college back in May, and since my graduate program did not start until September, I was fortunate to have quite a bit of time this summer to explore further away from home. I've been slowly prepping and cataloging over the past couple months, and figured I would share some of my favorite finds that I haven't shared yet. First up is dump piles of Silica Shale (Middle Devonian) in Paulding, OH. My university was not far from here, so this is really where I started fossil hunting. I've been here quite a few times, so most of what I found I already had in

I'm slowly making my way through finds from the summer and have come across a couple specimens I don't recognize. The first one is from the Platteville Formation of SW Wisconsin (Middle Ordovician). The second one is from the Maquoketa Formation of NE Iowa (Upper Ordovician).

Trilobite Calymene celebra from Silurian of Wisconsin
traveltip1 posted a topic in Fossil Hunting Trips
I found these 2 specimens (molds unprepped) of the trilobite Calymene celebra, the official Wisconsin state fossil, in the Silurian of Wisconsin. -
Just came back from a short trip to the driftless region of SW Wisconsin and we found a strange fossil in a road cut. I thought it was an algae at first, but I can't find any similar images. Sort of just looks like the rims of a rugose coral, but tiny? Found in Platteville formation.

2 more Halysites 'chain coral' from Silurian in Wisconsin, acid treatment
traveltip1 posted a topic in Fossil Hunting Trips
Here are 2 more Halysites 'chain coral' that I found in the Silurian of Wisconsin. The rocks were soaked in diluted muriatic acid for several hours, to partially dissolve the matrix and reveal the chain corals.- 3 replies
