Found these in a limestone formation near Bocairent, Spain. From some quick research it seems to me like these might be from the upper devonian, and some look like nautiloids? One of them looks like a coral. Perhaps crinoid also? Would love some help on IDing these if anyone has any ideas!

Been trying to figure out what these guys might be. I can see the resemblance to an internal cast to a rugose coral but they show shells that do not look like the horn corals here and they are much larger and at least one specimen I have seems to be bent and they seem to stay more parallel sided than the horn corals. The last image is a cross section one that seems to show some chambers.

I live in southern Ontario County, New York State. I found this in my long gravel driveway, meaning it presumably came from a local quarry. I believe it to be shale and am wondering if it is a cast fossil of perhaps a cephalopod. I am a raw newbie; this is my first post about a fossil. Thanks!

Never thought I'd see the day where I would hold one of these. But that day came this Saturday when my girlfriend found this. Location: SW Wisconsin Sinnipee Group- Platteville fm Age: Ordovician Total shell Length: 25 in/ 63.5 cm Total diameter of living chamber end: 6.98 cm Living chamber end siphuncle diameter: 2.22 cm Total diameter of tapered end: 3.49 cm *note the tapered end has matrix, however it was still able to be measured semi accurately. Tapered end siphuncle diameter: 1.27 cm The siphuncle appears to be off center. However there is extensive wear, so I'm not sure if it's a result of environment or an attribute of the shell. Much of the shell exhibits a ribbing texture from the septa. They are angled, and not perpendicular to the ends. Apologies for the difficult lighting, I tried to excentuate this trait with an illustration. The ridges formed from the septa appear to sit around about a 15° angle. This feature runs the length of the shell, and I was able to count 82ish from both ends completely. Again, in most parts of the shell it's very hard to capture in images, so I've tried to show it in some form as much as possible. I would love any help on this, I've tried to be as meticulous as possible.

Not sure if I've found a fossil. Can anybody help me ID this, please?
Flashgordon posted a topic in Fossil ID
Hi everyone, my sister and I went out on walk at a local nature reserve this morning in the UK. With the weather being so hot recently, water levels have dropped in the ponds and the lake that are situated in the reserve. I found this shell sitting at the edge of a very hidden pond. It was NOT found in rock, it's very light weight, very fragile. Is it still a kind of fossil? Thanks guys

I picked this up on my last trip along AA highway in Kentucky. It's about 4cm long. I thought it was a crinoid stem. Recently I saw a YouTube video where someone found a fossil very similar to this and called it a cephalopod. So that left me confused. So I figured I should just post and ask here. (If I need to provide more information or pictures please let me know)

Did I find my first cephalopod(s)? Last one could be a crinoid

A new, complete family tree of Cephalopoda
Bringing Fossils to Life posted a topic in General Fossil Discussion
After a lot of research, I made this family tree for all of Cephalopoda. I have posted major resources below.

I found the following rock and several other highly worn pieces in a creek bed that look to contain fossils of sea worms, etc., Fossils were found southeast of Fayetteville, Arkansas (long 35.68815 x lat -93.74751). Geologic timing - Ordovician? Rock is quite dense, and what was originally shale, is now metamorphic. The "segments", or wider features, measure the same thickness between seams, so i'm guessing this to be from a once living organism. Would love any ideas on this one!

Hi everyone, I recently took a trip down to New York for fossil and mineral hunting and I found this cephalopod(?) fossil on a Utica road cut. Any ideas on species or if it is a cephalopod? A friend said it could be pyritized, but I'm not sure.

10 SW Ohio Ordivician mini-collections to trade
hrguy54 posted a topic in Member-to-Member Fossil Trades
I would like to expand my overall collection. I have collected a ton of SW Ohio Ordivician fossils over the years. I believe that most non-Ohio collectors are unaware of how great this area is for collecting. I'd like to get other specimens from other areas. I have 10 "mini-collections" (samplers?) made up of typical SW Ohio fossils, minus the trilobites (they aren't really so widespread). The collections (similar to that pictured below) will include 2 horn corals (one with beekite), a gastropod, a cephalopod, the top valve of a rafinesquina, and 6 complete brachiopods...a hebertella, a vindlandostrophia ponderosa, 3 different kinds of lepidocyclus, and one of the following... a glyptorthis, a plaesiomys, or a retrorsirostra (I say one of these three because I struggle to tell them apart). I would like to trade to different people from different areas other than SW Ohio/No KY/E Ind. Or from the Devonian in NE OH and around Penn-Dixie...I'm pretty good on those already. All pieces will be in very good condition, prepped and ready to go. I would like the same in return. Just because I'm offering 11 pieces doesn't mean I want 11 from you....I want a good quality representation of what is commonly found in your area...we can discuss/negotiate it. Of course, send a photo. If you want to suggest other trades/sales I'll listen. Right now I will not consider overseas shipping. PM me if interested.
