Sorry for lack of scale! Cambrian-Devonian rocks here. Found in the side of a building.

Found in the side of a building in Wisconsin, Cambrian-Devonian rocks here. Any ideas? Thinking bivalves or a bivalved arthropod. Sorry for the lack of scale! Each one is about the size of an apple seed
-
I found this in an abandoned fish nest in a human-made lake. One of my favorite finds!
-
Found in Paleozoic gravel alongside crinoids, corals, and gastropods. Sorry if this is just wishful thinking! Thanks. The rock is about an inch tall

Milwaukee formation mystery fossil. Find a load like these
SilurianSalamander posted a topic in Fossil ID
I find lots of these external moulds/trace fossils at the Milwaukee formation I hunt at. Any ideas? I’m stumped. Devonian terrestrial and marine deposit
-
Does anyone have an ID for these?I think the first may be a bryozoan?
-
Paleozoic rock. I found this looking back through some scrap rocks. I think this is a stone I found some crinoids, brachiopods, horn corals, and a trilobite in before. .75 inches long (sorry for not including a scale in the picture) thanks!

Here's something I explore frequently. This is a section of the Niagara Escarpment in Central Wisconsin. It consists of Silurian aged sediments, predominantly dolomite and limestone formations. It extends for hundreds of miles and can be found as far from here as New York. This area is locally known as The Ledge, and is as treacherous as it is beautiful. People have actually died here, drawn in by The Ledge, only to stumble over. Caution is advised if visiting. I have navigated and explored this labyrinth like formation my entire life. However some depths I dare not travel to. This ladder pictured above, is the only human made structure I've found here. I have yet to see where it goes. If you ever run through Wisconsin, I highly recommend you look at our ancient attractions. The Ledge represents only the tip of the iceberg here in Wisconsin.

Found this echinoderm in Paleozoic rock. Crinoid calyx or something else?
SilurianSalamander posted a topic in Fossil ID
Found in some landscaping gravel I’ve found boatloads of crinoid stems at. Brachiopods and gastropods are not too uncommon in those rocks. Paleozoic, likely Ordovician-Silurian.

Need some help on these maybe fossils quarried from Blackberry hill, Wisconsin
SilurianSalamander posted a topic in Fossil ID
Found in the side of a building and in the surrounding landscaping. From the Cambrian seashore sandstone of Blackberry Hill Wisconsin. The place is known for its fossils of mass jellyfish strandings and its trace fossils of some of the first arthropods, mollusks, and other animals on land. What are these? Thanks!

I went to Estabrook two days ago just because I was in the area. I've hit this area multiple times before. Despite its low fossil yield I think it's an excellent place to start for any new fossil hunters getting into the hobby. The sole outcrop to be found here lies under the bridge overlooking the river rapids. It extends for roughly 30-45 feet. There are soils in the area that occasionally produce small bits of brachiopod and crinoid stem fragments as well. However I mostly keep to the main rock outcrop. Your most common finds within the park are tons of brachiopod fragments. If you're lucky, you'll find a complete one. I also frequently find dissarticulated crinoid stem fragments and ossicles, most are so small I usually dont collect them. The third and final fossil I've encountered were small (usually) bluish gray bryozoans. They can be found alone or mixed into hashplates with crinoids and brachiopods. I've heard of people finding trilobites such as Eldregeops and some unidentified taxa. I haven't collected any of these yet, however any newcomer could. One person I correspond with at my university claims to have found Placoderm remains from Eastmanosteus, but I have no evidence for that claim. Regardless the easy to access location and ammentities from the park make this spot excellent for people who have young children. Just be wise with your collecting, and stick to non hammer collecting, as the authorities frown upon that within the park.

Found this today in the Platteville formation, SW Wisconsin. In the Mifflin member specifically. From what I see, it looks like a trilobite cephalon? I'm thinking Thaleops ovata. (Cap for scale)

Years of searching Wisconsin's various websites and old Geo surveys have always yielded varying levels of success ranging from mediocre, to misses entirely. Not this time, this is effectively the best hunting I've ever had in my home state. Period: Ordovician Formation: Platteville Location: SW Wisconsin Endoceras? I say that primarily based on size. Goniaceras, the flattened curved shape seems to support that? Gabriceraurus mifflinensis? It is a fragmentary cephalon, but that species is more common than other Ceraurids that I've read about. Sinuites? A common gastropod, I saw maybe 30 of these, but only grabbed a few. Unkown gastropods and a large bivalve that I recovered. I've only ever found one other bivalve from Alabama. An unkown brachiopod. Reminds me of Enteletes from Kansas. I really can't seem to find anything on these at the moment. A Strophomenid brachiopod. These are my favorite variety, I've got at least 200 from Michigan alone. Some various hashplates with Rugose corals, gastropods and other various Fauna. I found 3 productive locations worth a repeat on my scouting trip. Here was a singular find I recovered out in the boonies near the Iowa border. Ive got some 3 and 4 foot long associated crinoid stems from Kentucky, but this is far better than any little fragement I could ever get in Milwaukee. Measures roughly 7 inches. This trip was a real game changer, I understand now that Wisconsin is ripe for fossil plunder, for those able to find its secrets.

Hey guys, I was in the driftless area fly-fishing, and I found this fossil in a public access creekbed. I'm certain it's fossilized coral, but I was wondering if anyone here knew what kind it was, and if it's of good quality. I'm also curious as to why it looks different than many coral fossils I've seen online (not smooth).

Found this larger chunk of rock (too hard to be modern charcoal) while sifting for microfossils. It has a metallic look to it and is fairly brittle. It was found on bradford beach on Lake Michigan and was likely eroded out of the mid Devonian Milwaukee formation which is known for its coalified trees and giant fungi. this looks like a lot of coalified wood I’ve seen pictures of, but I’m pretty new when it comes to plant fossils so this might just be mineral. Thanks!
-
All Devonian -ish. First is from port Huron, second is from the Milwaukee formation, third is from the Nike missile site in Waukesha WI
-
Found at work among crinoid, brachiopods, silicified corals as well as a possible cephalopod and some silicified stromatoporoids. Silurian SW Wisconsin. Looks kind of like a cartoon bone in shape
-
Found at work. Ordovician to Devonian. It tapers so it’s not a crinoid stem
-
Looks like it’s been turned to beekite. Found in Paleozoic gravel alongside numerous gastropods on a rail road.
-
Found two of these fossils now. Both on beaches that are probably Devonian in age. One is from SW Wisconsin on Lake Michigan and the other is in the Lower peninsula of Michigan from the shores of Lake Huron. Organ pipe coral or some sort of burrow trace fossil? Thanks!
-
Can anyone help me narrow down these maybe gastropods?

Is this a conulariid? Found this weird imprint in the same rock as some brachiopods. Found armored fish bone, crinoids, corals, and bryozoans.
-
Found in a river bed along with several other fossilized (Jasper\Agate) items and glacier till. River is on the edge of the drift less area in southern WI. Some pictures have a smaller rock (6 CM x 3 CM) for reference. Thank you for looking. Iroh...
-
Found among loads of agates and quartzite in a gravel bed. Looks like a snail shell to me. Thoughts?
-
Stromatoporids, other sponges, or not a fossil? Thanks!
SilurianSalamander posted a topic in Fossil ID
All collected in gravel and beach rocks from SW Wisconsin. Thanks so much for the help! I love this community:)
