Relevant info first: This was found in Petoskey Michigan while looking for Petoskey stones. It was found in partially buried in sand. It is quite large and rather heavy. As pictured in picture 5, there is some sort of opening at the end? I can't get a very good picture of the inside, it's hard to get light where i need it and take a picture. the hole looks to maybe be about a 1/2 mm deep, and less than that wide. I took to reddit, albeit with less detailed photos and was told it was a straight shelled nautiloid cephalopod from the paleozoic, and that it was a brevicone, which I'm hoping someone can confirm or deny, or point me towards relevant info. I was trying to find more and found this on your forum, which is the first thing I've found online that actually looks something close to what I have: Anyways, Thanks for looking, and any help you can offer.

Oecoptychius refractus a weird ammonite from Saint-Laon (France) - Callovian - collected in october 2020 -
Location is in Missouri The area is dated to the Pennsylvanian Formation: Probably apart of the Raytown limestone member Found this weird fossil on my latest fossil hunting trip, I personally believe it to be some sort of Amminoid since the pattern seems to extend away from the shell and not towards it, but I have only found Nautiloids in the area ( Only 2 spiral shaped specimens that do not look like this and 3 cone shaped.) If anyone can Identify if this is a an Ammonoid or something else I would love to know more! the middle Section with the weird ball like pattern in the middle and what I assume are gas chambers around it

I was trying to find the longest straight shelled cephalopod length but was unsuccessful, I heard anywhere from 7-14 feet. What's the real answer? Thanks.

Hi everybody, I was wondering if you could help me with this. I found this rock among the Ames Limestone around Pittsburgh. The limestone's chock full of crinoids and corals, but I wasn't sure what this fragment was. It looks like it might be from a cephalopod (belemnites or bactrites maybe?), but I'm really not positive. Could you guys help me out here? Thanks!

This was found in southern Colorado. I’m not sure what it is.

Straight Shelled Cephalopod Identification (Pennsylvanian?)
Thomas.Dodson posted a topic in Fossil ID
I collected this little worn cephalopod in a stream in Peoria County Illinois. The area is primarily Patoka-Shelburn Formation Undivided (Pennsylvanian) but it wasn't found in-situ. I sectioned a piece for identification and the siphuncle seems large for the Pennsylvanian cephalopods known from the area. To my eyes it looks a lot like Actinoceras (which I guess would mean Ordovician) based on the position and size of the siphuncle. Does anyone have any other ideas?

From the album: Delaware Fossils
A Gryphea vomer bivalve made itself at home atop the internal mold of a tiny Baculites ovatus cephalopod. The whole thing is about 3 cm tall. Found in the Cretaceous spoils sands of the C&D Canal, Delaware -
Hey guys, the first one actually doesn't looks like a cephalopod, maybe part of a trilobite (from the Baltic coast)? 2. This flint remembers me of something from the bottom of the sea. Any Idea? Thanks in advance!

Hello all, I don't know much about cephalopods and really could use your help. I found this small rock with the tiny nautiloid specimen in the banks of the Rock River in Ogle county, Illinois. The area's bedrock is Middle Ordovician (Mohawkian, Ancell Group). I believe it belongs to the order of the Actinoceridae. The "camerae" end in double pointed arches instead of a straight edge, just as Wikpedia's illustration shows in the 2nd pic below. What seems to be unusual in my specimen - can't find any photos of this anywhere - are the rounded camerae, vs the tightly lined-up straight banding on other specimens. (I'm not sure about the correct terminology...sorry). If I'm not totally off base, is there a chance to narrow down the ID further? Thanks in advance. General form of Actinocerid:
