I found this specimen in Middle Pennsylvanian black shale in Illinois. It measures maybe 8mm in the widest dimension. Honestly not even sure if it's a fossil, never seen anything like it. Any ideas? Part Counterpart

Hey guys! I apologize in advance as I couldn’t get any measurements. I was packing to move and I have it in a box on a truck on the way to the new house. I found this specimen in the Appalachian coal fields of Eastern Kentucky. At first glance I assumed it was a leaf but as I looked closer it looks astonishingly like a tiny insect wing. The rock contains additional fossils and I excavated the layer this piece came from and found many lepidodendron and calamite fragments. The fossils I have found in this layer are extremely well preserved and extremely fragile so I tried my best to get this piece packaged up very well and somewhere safe after I took pictures. I’m not certain as to what this is so I appreciate the help in trying to identify it.

Hey guys, this is my first post to this forum and I’m excited to be here. I am an amateur but I have come a long way when it comes to fossil hunting and I have a pretty large collection of quality fossils. I found this piece in the Appalachian coal fields of Eastern Kentucky, mixed in with other fossils from the Pennsylvanian. To me it appears to be some sort of invertebrate fossil but it is preserved in a type of sandstone and as far as I could guess I would imagine that an earthworm-like specimen would be too delicate to be preserved to this detail. It is definitely weathered by the rain and snow we have had lately but you can still see an amount of detail. A friend of mine who is also an amateur suggested it could be a type of millipede but we simply do not know for sure what it is. Thanks for the help!

Had this concretion open today. I'm pretty confident it's something vertebrate. Maybe a lungfish plate? @jdp @RCFossils Thanks for any help.

I found a few interesting things at a road cut near Brady TX that I had went to with the Austin Paleontological society. I found a layer that had about 140 starfish and in the same area some of the layers had pieces of petrified wood and what looks like tiny leaves. Any info is appreciated Thanks

A couple months ago I received a message from a friend letting me know of an opportunity to collect a usually inaccessible Mazon Creek site. The area used to be a popular with collectors but has since been reclaimed as a subdivision. A house was finally being built on one of the last undeveloped lots, and this meant spoil piles while the foundation was being laid. I initially planned to go later in the week, but instead decided to wake up early the next day and drive down. This ended up being a lucky decision, as the foundation was filled that very next night. The site was not superbly productive - I only gathered about a gallon of concretions for the two hours I was there. I have finally finished processing them, and although I did not find anything super rare, I am still thrilled to be able to add specimens from this site to my collection. The site Some in situ concretions Here are the finds I kept. Most of the other concretions were blanks or had poor quality plant bits. Annularia inflata Annularia radiata Radicites columnaris (an indeterminate root) A nice three-dimensional Myalinella meeki bivalve

Hi! It turns out that my property is full of fossils and I’ve decided to try to collect some. While my ultimate goal is to find a wooly mammoth tooth…I’m a realist and every little crinoid earns my fascination.

Collected from Atrasado Formation (Pennsylvanian carbonate shelf formation) Best photos I could manage: And, for fun, some real fossils from the same venue: Bryzoans: And this I thought was a horn coral But now I'm less sure. Under the loupe, it appears to be more shelly. I could not get a decent photograph to show it, but the large end (what isn't embedded in the rock) is open and seems to have triangular structures along it. A serrated rim, if you will.

@JamieLynn's post about the recent PSoA field trip to Wilson Clay Pit reminded me that I was in need of creating my own trip report too. Early last month I made my first ever trip to Wilson Clay Pit in hopes of finding some of the incredible Late Pennsylvanian echinoderm and vertebrate material that I had read so much about. I was a little nervous about visiting (after hearing stories about rattlesnake encounters), so I was fortunate to convince a friend to join me. He must have brought the luck because not only did I find two nearly complete Petalodus teeth and a nearly complete Petalodus crown, but I also found an articulated crinoid cup with three partial associated arms and a trilobite pygidium. Beginners luck I guess! A big thank you again to @Ptychodus04 for the prep work on the crinoid cup. Petalodus ohioensis Ditomopyge scitula pygidium Delocrinus vulgatus crown with associated arms and boring sponge damage Crinoid Stems, including one with boring sponge damage Archaeocidaris sp. Plate and Spine Polypora sp. Fusulinids Derbyia crassa Jurensia symmetrica Punctospirifer kentuckyensis Neospirifer cameratus Neochonetes granulifer Crurithyris planoconvexa Composita subtilita Linoproductus cora Hystriculina wabashensis Desmoinesia muricatina Marginifera fragilis Allorisma terminale Palaeoneilo oweni Edmondia nebrascensis Euphemites vittatus Septimyalina perattenuata

I found this goniatite at an exposure of the Sausbee Formation (Early Pennsylvanian; Morrowian) in Oklahoma. I have tried in vain to identify it to even a genus level. I was wondering if anyone knew what this goniatite is. The only identifying mark that I could see on the fossil was a single band on the underside, as seen in the third photo. Any help would be greatly appreciated. Thank you so much!

The Paleontological Society of Austin did our annual field trip out to Brownwood Texas. It was a beautiful day for collecting. Super blue sky and temps starting in the 50s and warming to the 80s. This site is so big that I have not even begun to explore all of it so decided to head to a different area than I had previously collected in. Walking toward the back I had my first nice find - a lovely little crinoid calyx, just shining in the dirt! Next find was what I HOPED was a complete Neospirifer, but sadly, the underside was not so good. Still nice though When I got to the back, there is a lovely little pond surround by the cliffs of this old quarry. Found a "non fossil" My first "best" find of the day was this partial Petalodus tooth. So far I have only found partials, but this is the best one so far, at least it has the tip of the tooth! And the texture is just lovely. It's a nice size too, just over one inch: and then I found this little piece. I almost didn't pick it up because it didn't look like much. I thought it might be another chunk of a Petalodus and actually almost left it there. But I then went back and said what the heck, even a partial is good. AND I AM GLAD I DID GO BACK!! Because upon photographing and being able to see better detail....I'm pretty sure it is Deltodus tooth! Another Pennsylvanian shark that I had seen a few picture of but not one in real life. So I am super happy with my "almost got away" story! hahhaha! It is also 1 inch A few more of my favorite finds from the day: Echinoid plate Bryozoan Crinoid Crinoid: And I posted this on my Fossil a Day thread but here it is again. All of these colors of crinoids are found here. That just ever ceases to amaze me! I am already looking forward to my next trip there!

I've been spending a lot of time lately studying the Mazon Creek flora, and am continuously astonished by the diversity and quality of specimens that can be found. I don't think we see enough plants on the forum, so I figured I would go ahead and share some of my favorite finds. First is a specimen I recently shared, and a fitting start to the thread. This is Crenulopteris acadica, the most common true fern found in the Mazon Creek flora. It has been the most common plant I find, accounting for probably half my finds. Next is a favorite of mine. This is a section of Calamites (probably C. cisti) encrusted by a number microconchids. I always enjoy finding concretions with associations of different species. Last for now is a specimen of the rare seed fern Callipteridium neuropteroides with great coloration.

I was inspired by @Mark Kmiecik and his quality photographs to finally learn some basic image editing. I had this beautiful Crenulopteris acadica fern open yesterday and figured it would be a good specimen to make a first attempt. Let me know your thoughts.
