As I continue to explore (see my prior thread Earlier today I visited the Upper Freeport Formation south of East Liverpool. These are sandstones associated with the Upper Freeport coal, so we are at the end of the formation. I have been up here repeatedly over the past year but never explored rocks this old in the area. It was snowing for about two hours this morning but I still spotted some cool fossils. Unfortunately while I saw the Upper Freeport coal, I didn’t have the opportunity to collect in it. Here are two separate medium sized impressions of lycopsid trunks. I then moved further into younger sediments, revisiting where Pteroplax was collected (Romer, 1963). This is a well known site in the literature, reported in most of the Ohio Pennsylvanian age invert reports of the latter half of the 20th century. I’ve been here before, though we mistakenly descended to the base of the cut along the rail line which was frustrating. The circumstances of how Pteroplax was collected are interesting. Look the paper up. That unit it was produced from is no longer evident and completely overgrown and slumped but it’s fine because I was here for the Ames limestone. Everything I collected here was typical of what I have seen of the Ames limestone in eastern Ohio so I have omitted pictures. Afterward I moved on to another section that exposes a larger portion of the Glenshaw Formation (the Ames is the terminal Glenshaw transgression, the Upper Freeport coal is below the Glenshaw’s lowest unit). Here are some Pine Creek (Upper Brush Creek) brachiopods. One is a productid and the other is a part and counter part of a spiriferid (?Neospirifer). In the Cambridge limestone, we found this badly preserved snail. Perhaps with some preparation, it can be identified further. It is fairly beat up. At this locality, the Cambridge is very coarse grained and hard. The snail is not exhibiting the typical preservation qualities of other invertebrate fossils found here. In a younger unit, I found this partial Deltodus tooth as well as a possible actinopterygian scale (I have my doubts but friends are certain). Both are hanging out with broken bellerophontid snail pieces. Tomorrow I will be in the Mercer (Pottsville Group) which is older than anything you’ve seen in these two threads. If I find anything worth sharing, I’ll share! In the future I will be updating this thread for the entire month (and maybe the year) instead of starting new threads.

Some of these fossils are so tiny it's really hard to get clear pictures, like #12, these are scattered in several places not much bigger than fishing line, guessing echinoid spines? #7 undecided if these are brachiopods or maybe lungfish teeth? #8 looks like a battle ground, deconstructed echinoid and parts of crinoids? Not sure what to make of all that

Pennsylvanian fossils in Cretateous creek need a little help!
Lone Hunter posted a topic in Fossil ID
This is my last post for the foreseeable future and want to get an ID on all of these. Found this last summer after big flood churned up creek in Eagle Ford formation, it's not unusual to find imported erosion control rocks with crinoid stems but they're usually big and heavy and harder than concrete so when i saw this small one I grabbed it. I plopped it down on dog bed and took one practice pic (about 10" long #1) then when I picked it up it started to fall apart and I realized it was still wet, never completely cured, still had soft clay. I'm not familiar with rocks out west is this normally how fossils are found there? How did this rock manage to get dug up, loaded, travel at least 50 miles then get dumped and never dry out or get smashed to peices? Pic #2 is what remained after removing all soft parts and drying. Anyway it was a mini fossil hunting trip all in one rock and just wish everything wasn't so tiny! #3 was the prettiest but can't tell if it's a brachiopod or not. #4 Marginfera? #5 brachiopod? #6 columnal I thought would be easy to ID but no. #9 Composita sp? #10 unknown gastropod and crinoid stems. #11 another Composita? I'll do a second post with the rest it's too many pictures.

Hey guys! It’s been a long time since I’ve been active on the Forum, but I have an exciting update - I just published my first paleontology paper on Christmas Eve! It’s a short paper documenting two shark species that are previously unreported from the LaSalle Limestone of northern Illinois (you guys may know it as the Oglesby roadcut!), Heslerodus divergens and Ossianodus sp. I’ve added the pdf of the paper here and here’s a link to it as well. Thanks to everyone here that helped give info about the site, especially @deutscheben! Gieser_et_al_2023_Kentiana_5.pdf ***Calling all LaSalle Limestone/Oglesby roadcut fossil hunters!*** If you have collected any shark or fish material from the Oglesby roadcut and would be willing to contribute to science and the growing knowledge of the (severely understudied) Paleozoic vertebrate diversity of Illinois, please contact me! Hobbyist fossil collectors have made some of the best finds in paleontology, and I would love to see what you all have collected from the site. This area’s fish diversity is much higher than is currently known to science and I would like to work on documenting it. Thanks! Email - rgieser2_AT_illinois.edu or you can just contact me on this site as well

Possible Diplopoda-3.tiffHello all, I’m hoping someone could lend their eyes and give their opinion on something I found. This is from a small rock I found near the Narragansett Basin area of Rhode Island. I recovered it from an undeveloped plot of commercial land that is sometimes used as a construction fill dump, so I don’t know where it originally came from. It appears to have a symmetrical pattern, but I could be seeing what I want to see. Rhode Island fossils are from the Pennsylvanian Period (mostly ferns, horsetails, some trilobites and occasional insects). If anyone could shed some light on this I’d be very appreciative!

Hello, Could I get an ID on this mazon creek unknown? It has pretty high relief and strong segmentation with makes me think arthropod like a millipede, but I don't see any legs so maybe it's an annelid worm or something.

This mazon creek pit 11 concretion opened a couple days ago and looks kind of like a ribbon worm but the preservation is different than examples I've been able to find. Any insight would be appreciated thanks. Also my word suggestion prompted me to say Happy Thanksgiving!

This one was sold to me as the acorn worm Mazoglossus ramsdelli... it seems to match photos I see, but I'd like a second opinion, please: This one was sold to me as Archisymplectes rhothon ('ribbon worm') but I'm less confident about this one, so, same question as above. If it's not that, what is it?

Fossils in Pennsylvanian shale from the Narragansett Bay Area in Rhode Island?
DavidL posted a topic in Fossil ID
Would somebody please help me make sense out of some of the things I’ve found? The stuff looks like fossilized organic material to me, but I really don’t know what I’m looking at. These are embedded in Pennsylvanian period shale found in the Narragansett Bay Area of Rhode Island. Some were found in woods near the Blackstone river, others were found in an undeveloped plot of commercial use land that’s been used as a dump for all sorts of rocks used in construction, etc. Any help would be greatly appreciated!

Hello all! I just recently purchased this specimen which was indicated to be from the Carboniferous, Bashkirian-Westphalian B, beds of Poland, dated to be Pennsylvanian at 314 mya. It was sold to me as a Trigonotarbid abdomen. The white square is 1 x 1 cm for scale. While I am no expert on arachnid orders, it appears to be lacking the segmented plates that surround the perimeter of the inner abdomen. Could this be part of some other segmented terrestrial arthropod, or could this feature be covered up by surrounded rock or have been damaged? I will be posting pictures of the specimen below, please let me know if you have any questions or need further information to support a conclusive ID. Excited to hear y'alls input!
