*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

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

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

My wife and I went on a 7500+ mile ramble to break out of our COVID doldrums. Due to the virus we had to change up many of our original plans... which conversely added a number of additional fossil hunting locals as they allowed us to mostly avoid our fellow humans and maintain social distancing by many many miles. As part of our trip preparations my wife sewed us a number of masks, including a whole series of fossil hunting masks for me. Originally we were supposed to stay in Chicago, but we elected to avoid staying in the city, so we only got to do a drive by

I had attempted to ID similar fossils awhile ago but feel they were lost in the trilobite photos. So today, I will only present these new unknown "blobs" from the Cambrian , Eau Claire Formation of western Wisconsin in hopes to definitively ID these. Maybe they are even geologic. Good Luck!!!!!

Halysites 'chain coral' from Silurian in Wisconsin, acid treatment
traveltip1 posted a topic in Fossil Hunting Trips
I found this rock containing a Halysites 'chain coral' in the Silurian of Wisconsin. I soaked it in diluted muriatic acid for a few hours to partially dissolve the matrix and reveal the silicified coral fossil. Photos are before and after acid treatment. -
Going through old stuff and found this. Measures 1cm.Platteville formation(?), WI. Any ideas?

Found in southern wisconsin about a mile away from the Mississippi River.

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

Hey everyone, was thinking about traveling to southwestern Wisconsin for some fossil hunting. I want to learn how to looking for trilobites.... but I have no experience over there. I prefer get together with someone for fun! Let me know. Send me message. Mike P.S. is midwestpaleo.com down for good?
