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!

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:

Nautiloid? And what species would it be? (Solved also No soft tissue)
Samurai posted a topic in Fossil ID
Timer period: Pennsylvanian Location: Missouri Formation: Not exactly sure. Found in an abandoned rock pile containing limestone from the Iola Limestone Still it is a possibility it came from limestone from the Upper Winterset limestone. Hello! I found this nautiloid a long time ago and it was too heavy for me to carry the chunk of limestone that contained it, but before I left I got a few pictures of the specimen! Once I observed the photo a few weeks later I had the biggest regret of my life as it might contain an impression of soft tissue! I don't know If my mind is playing tricks on me but I think it might contain soft tissue. The thought is driving me crazy since I am always doubtful when I find fossils like these and due to my own lack of experience. Can anyone confirm if it does contain soft tissue? Is this a tentacle? or my imagination? Here are photos I edited in photoshop in order to see if I can make the features more visible (Above) Added more saturation and darkened (above) Added saturation and brightened the image I would like to note I have returned to the area but I have had no luck in finding it again and these are the clearest images I could obtain and I apologize for the blurriness Here are the images in their natural file size and some additional images: https://imgur.com/a/80wzODc If possible I would also love to know its species but I find that unlikely since it is bisected and poorly preserved shell wise.- 6 replies

I found this intriguing rock in Northwest Arkansas, in the Bloyd Formation I believe (carboniferous). It really looks like a steinkern to me, but I've only found limestone steinkerns before, hence my doubts. It's approx. 3" x 2"
