I found these Devonian bivalves (?) at the Milwaukee formation at estabrooke park in Milwaukee Wisconsin. I think the first one could be a bivalved arthropod like an ostracod and the second could be part of a brachiopod. Any help is appreciated! Thanks. Sorry for lack of scale! I just put one in my rockhounding bag.

Hello! I found these fossils(?) at Estabrook park which is part of the Devonian Milwaukee formation. They appear to be external moulds. These were found near the Lindwurm and Berthelet Members. Are these jawless fish? Big brachiopods? Non-fossils? I’m stumped on these. The formation is known for its plants, giant fungi, jawed and jawless fish, Cephalopods, and Conulariids. So sorry for the lack of scale! I need to start carrying a tape measure with my fossil hunting backpack.

I was wondering if I found an external mould of the Devonian gastropod Platyceras. The fossil curves in the rock which was hard to capture with the lighting. The rock was too big to carry back and I didn’t have a ruler with me so I apologize for lack of scale. Thanks!

Crinoid calyx or echinoid? Found in gravel with Ordovician-Devonian fossils. About 2cm across at the widest point. Druzy coating over the fossil which seems to be an external mould. In orange jasper. Thanks so much!

I found these burrows in Ordovician-Silurian rocks in Waukesha Wisconsin. I found hundreds of these just a few weeks ago in Green Bay WI (Ordovician) any way to identify what animal made these burrows? Thanks! ps: so sorry I forgot the scale

Found these weird spirals in this chunk of agatized rock. Devonian from Bradford beach in Milwaukee. Thanks!
-
Silicified sponge(?) fossil found in Wisconsin Paleozoic gravel. Likely Ordovician or Silurian, possibly Cambrian or Devonian. Thanks!
-
The preservation isn’t the best. Broke open a big piece of dolomite with a nice brachiopod. Found that I had shattered whatever this is and exposed some nice silicified chain coral. It’s sorta a hemisphere with internal structures. My best guess would be some sort of echinoid. Silurian Wisconsin, Hartung quarry

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!
-
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

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

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.
-
Can anyone help me narrow down these maybe gastropods?
