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.

A friend asked me to look at this fossil he discovered at the base of a limestone bluff in NE Iowa it is a Native American winter camp and cave complex. Have found trilobite and marine fossils in the area. It looks remarkably like a tall molar or short bone but a couple hundred million years too old. Does anybody recognize this? My best guess is that is a stalk of a plant precursor?

Silicified sponge(?) fossil found in Wisconsin Paleozoic gravel. Likely Ordovician or Silurian, possibly Cambrian or Devonian. Thanks!

I found this in an abandoned fish nest in a human-made lake. One of my favorite finds!

Found in the stone steps at estabrooke park quarried from the Devonian Milwaukee formation.

Found this echinoderm in Paleozoic rock. Crinoid calyx or something else?

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

Wow. This was one of my favorite hunts I’ve had in a long time. I’ve been looking for Paleozoic sharks teeth for a really long time, and have finally stumbled across them. I took a trip out to southeastern Ohio, and I’m not disappointed to say the least. These sites were really small, but I found a LOT of shark teeth, and fish fossils as well. Here’s the finds: Shark teeth: These sharks teeth are a lot smaller than the ones I find at home, but they’re a whole lot cooler since they’re new. This one is broken. This one’s a really nice sharks tooth. T

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.

Found these at the Nike Missile site in Waukesha Wisconsin. I found a chunk of armored fish bone in the same area. This is an update on my last post with the moss cleared off more. Thanks!

Found in Michigan LP. Devonian age probably? Loads of corals and other agatized fossils wash up on that beach. This is the only one I’ve found like this.

Location: Vestavia Hills, AL Paleozoic While inspecting this rock, a tiny barb pricked my finger. Initially, I was thinking it was a tiny piece of plant debris superficially attached. However, as more of the area became exposed after cleaning, it appears to be clearly embedded. Also, additional similar areas became exposed. Unclear if they are part of the same thing or separate inclusions. My wild guesses: Spicule? Small arthropod leg (though I realize that is in likely to be preserved)? Bryozoa? Thoughts? Last 2 pics: Potential related debris sifted and

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

Found on the railroad tracks. Confident it’s an echinoderm based on the apparent pentaradial symmetry. Heart urchin? Probably Ordovician to Silurian stone. Definitely Paleozoic.

SW Wisconsin, most rocks being Ordovician to Silurian in age. None found in situ

Found on a railroad track with other Paleozoic fossils

Found while splitting fossiliferous rock

Found on my way down to my usual fossil hunting beach (Devonian) I’m pretty sure these rocks were brought in to prevent erosion though. Late pre-Cambrian - Devonian rock for sure
-
I keep on finding these but I have no idea what they are. Help!

Hello everyone, Some time ago I was talking about a gastropod fossil with an individual online who thought that it was an ammonite, During this conversation one thing was brought up that I have wondered about for a long time but have not actually been able to answer, and that is what exactly do we consider an ammonite? I have always thought that ammonites are the cephalopods with an external shell containing complex sutures which occur throughout the Mesozoic, but people have pointed out that certain sites talk about ammonites going back to the Devonian. I have always thought t
