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

I found this in an abandoned fish nest in a human-made lake. One of my favorite finds!
-
Sorry for lack of scale! Cambrian-Devonian rocks here. Found in the side of a building.
-
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
-
Found in the stone steps at estabrooke park quarried from the Devonian Milwaukee formation.
-
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!

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!

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.

Found at work. Ordovician to Devonian. It tapers so it’s not a crinoid stem

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 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!
-
Looks like it’s been turned to beekite. Found in Paleozoic gravel alongside numerous gastropods on a rail road.
-
Is this a conulariid? Found this weird imprint in the same rock as some brachiopods. Found armored fish bone, crinoids, corals, and bryozoans.

Last weekend I had the opportunity to collect in a quarry in southern Wisconsin. It appeared to cut through the Upper Ordovician Platteville, Decorah, and Galena Formations, although only the Platteville rocks were accessible. It was not the most productive trip but it was a new spot for me and I had a good time. Here's a site shot plus a couple photos of large hash plates I did not collect. The quarry was swarming with these baby frogs – I easily saw several hundred. Here are the finds I kept. Eoleperditia fabulites - giant ostracods A large cephalopod fragment (probably Endoceras) coated with pyrite crystals A nice slab of mollusks, including a very nice example of the curved cephalopod Beloitoceras

Can anyone help me narrow down these maybe gastropods?

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...

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:)

Found among loads of agates and quartzite in a gravel bed. Looks like a snail shell to me. Thoughts?
