I visited a coal mine last weekend with a group, and we had a good time finding Carboniferous era fossils. There were large volumes of plant fossils. I did find a few marine fossils (brachiopods) also. I found the "thing" below as well, which mystified me. I found it splitting a rock, and there was a counterpart as well. I did not retain the counterpart, perhaps I should have (it was broken). Formation: Pottsville Group Age: Pennsylvanian Period, Westphalian-A (312 million years old) .Jefferson County, AL Anyone know what this might be?

Split the limestone, and when tying to cleave down the rock, split the fossil. Lucky for me, it split in between the inside and outside shell. Going to glue it back together with paraloid. Highly probable Metacoceras.

I am having trouble putting a label on this cephalopod from the Upper Pennsylvanian, Graham formation, Finis Shale member, from Jacksboro Texas. The conch is crushed on the anterior end which distorts the apical angle but the intact posterior end shows an angle of around 12º and the cardinal ratio is about 2. My first thought was bactrites but if that is the siphuncle it appears to be very near but not quite in contact with the ventral wall, which I thought was a requirement for the whole subclass. It looks a little like the “doubtful” genus Cylobactrites with the foldlike ribs and missing ventral lobe, but the treatise shows those to be Mid-Denonian. Maybe the ribs could be described as annulations and the siphuncle as subventral making it a nautiloid like some Brchycycloceratidae but B. normale and B. curtum are all I see on the fauna list for the site and they have much large apical angles at around 22º and 40º. Any ideas?

This fossil was found at the North Attleboro fossil site, and I’ve had it marked down as a species of Sphenopteris but i’m not 100% certain

I put this on the microfossil forum as well, but wanted to give a look-see to this intriguing fossil! In my search for conodonts in Pennsylvanian stark shale (between Winterset and Bethany falls limestone) I routinely find concretions/nodules-most are powdery but sometimes i find teeth and other microfossils. Well much to my surprise, upon splitting my thousanth shale, I found a 1cm nodule, and within it, this apparent micro sea urchin-one of two in the nodule. From spine to spine (7:00-1:00) it measures just under 2mm in diameter I am refining my photog techniques with a newly purchased leica M420, phototubes, and a sony A660 camera, which produced this first photo of one of the conodonts. I am intrigued by these tiny urchins (if that is truly what they are! ). Thoughts, comments and any hope of specific i.d. on this or the conodont appreciated!!!!! (and how this wound up in the anoxic shall layer)-wasn't a surface find contaminant, but found upon splitting shale.....so ~300million years? thanks again all!...... Bone

Hi. Found among the huge limestone layer at the Caney River in central Washington County, northeastern Oklahoma. Pennsylvanian. It's a little closer to Kansas than to Tulsa. A few miles east of the Osage Hills (or Rolling Hills of the Osage, depending on the which map).

I tried to fix these pics with GIMP but this is the best I could get. Found at the Caney River in central N.E. Oklahoma It is at an angle and is concave, one half to two inches long. It is kind of leaf shaped with a series of raised bumps through the center. Further to the right, reminds me of a tiny mud daubers nest which the wasps have grown and left. Thank you.

Hi. This is on the Caney River, middle of Washington County in northeastern Oklahoma. It's in very hard matrix, can't do more than make a scratch on matrix surface. Pennsylvanian. Abou4" long, no more than 5" long. In the third picture what looks like a crack across the middle is just a shadow. Thank you.

Hello again Fossil friends! I have another fossil I need help with. Found with other shell and coral fossils in a river shore in north eastern Kansas, most likely Pennsylvanian. It looks to be maybe a sponge with exterior and interior... structure? Couldn't figure this one out. Maybe someone with more knowledge can ID it for sure.

Hello Fossil friends! I have a couple fossils(?) I'm going to see if I can get help identifying. I found all of them in the same local area of a river shore in northeastern Kansas, so I'm assuming Pennsylvanian time frame. I have some fossils that are obvious shells and coral, but these I'm not sure and would like your input! If you need more photos or angles, let me know. #1 I think is a fish vertebrae that's slightly flattened. It's about 1 cm x .3 cm.

There are fossils in the background gray sedimentary, but so much better preserved in brown! Why? Almost like this pile of creatures is on display, a 7 inch blob just laying on top of gray stone. I'm more interested in how these were preserved than what they are.

Hi. I know these are poor pictures so I understand if nothing comes from them. This 3' by 3' boulder looks like a big dirt clog up close but is solid. It is in central Washington County, northeastern Oklahoma, Pennsylvanian I think, on the Caney River. 99% of the ground you see it sitting on going down the river and around the bend is coral, but I see no coral in this boulder or the only other boulder (out of view). In this post, the lower middle spot in all three pics is what I am curious about. It's about a foot wide.

Hey everyone, I recently got a bunch of stuff from Mazon Creek, which I have zero experience with. I would really appreciate some help in identifying this stuff, so here's a few of the things. Everything is from Mazon Creek Pennsylvanian in siderite concretions, the scale bar is in mm. The picture labels are what came to mind looking at them. Thanks Everyone!

From the album: Missouri Plant Fossils
When this came out of the earth I was shocked by how many were bundled together as I mostly find only fragmentary pieces of one specimen. The small limestone chunk on the left is a piece that came undone at the site I found this fossil at. More images of these fossils: https://imgur.com/a/KnjIeqG Correct id by Fossildude19 -
Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale I was cracking Phosphatic concretions and this baby popped out! I was excited and thought I should share and ask what it is! I believe it is a cartilaginous fish spine, but I have little knowledge in such topics. Ps Information on good glue to glue together the cracked piece is welcomed!

It's been a long time since I've written a trip report. Not that I wasn't hiking, I was hiking like mad and finding stuff. Just didn't get around to documenting in the latter part of 2020. Too much craziness. A couple of days ago, I went in search of an extremely elusive shale formation, that contains some of the loveliest ferns I have seen. My records show I specifically planned 13 hikes last year trying to find another exposure. That was over 100 miles of fruitless searching. Zero. Zilch. Well, two days ago I found another small exposure. Scenic photos of the journey follow starting with walking uphill on an Ordovician rock bed The Ordovician transitioned into this Silurian bed with Devonian formations rising above it on the left Although fairly stumble-free walking this was relatively steep. That day I ascended 2,800 ft with my big pack full of tools, food and drinks. A nice shattered chert nodule in the Devonian. Just to show not everything has fierce thorns here, some 'Cushion Buckwheat'

While organizing today, I came across this Composita I collected a while ago in the Pennsylvanian of Illinois. I noticed it had something encrusting it, which was surprising since brachs from this site never seem to have any encrusting organisms. Whatever it is, it is not preserved super well, but it almost looks like a tiny productid brachiopod? Never seen anything like it. Any thoughts? @Tidgy's Dad

Mystery critter -Kiewitz Shale- SOLVED brachial valves still working on genus
LabRatKing posted a topic in Fossil ID
Finding a complete specimen is my white whale. Usually only find small fragments, these three are my most complete. Am able to use a few bits to get a “reconstruction” cannot figure out what these are. thanks in advance!
