    Possible insect wing?

    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.
  2. 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!

    Mazon Creek Lungfish plate?

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

    Starfish and leaves

    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
  5. 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
  6. 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.

    November Trip to Wilson Clay Pit

    @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.

    OK Pennsylvanian Goniatite

    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!
  9. 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!

    Mazon Creek Flora

    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.
  11. 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.

    More Texas Pennsylvanian Brachiopods

    I could use some help confirming the identities of these brachiopods from the Harpersville Formation (Upper Pennsylvanian). Using the slide deck for brachiopods on the DPS website I made a best guess. I would love to know if someone has different thoughts. Any help would be greatly appreciated. Thank you! #1- Marginifera fragilis #2- Desmoinesia muricatina #3- Hystriculina wabashensis
  13. For the most part, fertile ferns are rare in the Mazon Creek flora. The only exception being Diplazites, of which ~1/2 of all specimens are fertile. This is my first non-Diplazites fertile fern. I really like the interplay between the white mineral deposits, the brown matrix, and the scattered pyrite crystals - a very artistic specimen I think. My best guess is that this is Cyathocarpus hemitelioides, but I am not positive. Close up of a fertile pinnule Close up of sterile pinnules at the base

    Carboniferous Shells in Shale

    Hi! I was collecting plant fossils and found these shells. They are Pennsylvanian (Carboniferous), Conemaugh Group, Glenshaw Formation. I don't know what they are. Any help is appreciated, thank you.
  15. Here is an odd-ball I found yesterday. Recently I found a new marine / brackish layer of dark gray shale. My first discovery was two root pieces, which I'll showcase at another time. I also found a tiny Glabrocingulum grayvillense (gastropod) there. This particular rock had a brachiopod on it, and I was getting a closer look. The matrix was soft enough to stab with my tweezers, so I was digging around the margins. This very tiny piece appeared that looked very interesting, and even more complex under the microscope. It's very small. The further out photo shows it with a 1 cm scale. I feel like this is a known marine animal shape, but It's not apparent to me. You can see the opposite part of it on the top right of the following photo as well.

    Texas Pennsylvanian Brachiopods ID Help

    Over a couple of trips to several exposures of the Late Pennsylvanian Colony Creek Shale, I have collected a few larger brachiopods that I am not completely sure of an identification for. I was hoping that someone might know what these are. Any help would be greatly appreciated. Thank you so much! #1- ??? #2- ??? #3- Antiquatonia portlockiana? #4- Kutorginella lasallensis?

    A Fossil A Day.....

    A Fossil A Day....keeps the blues away! Or something like that... I started an Instragram account (jamielynnfossilquest) and am posting a fossil a day, so I figured I should do that on here, to REAL fossil enthusiasts! I'm a few days behind, so I will start out with a few more than one a day but then it will settle down to One Fossil (but I will admit, I'll probably miss a few days, but I'll double up or whatever.) I'll start with Texas Pennsylvanian era, but will branch out to other locations and time periods, so expect a little of everything! So enjoy A Fossil A Day! Texas Pennsylvanian Fossils: Nautiloid Agathiceras ciscoense Brachiopod Neochonetes acanthophorus Trilobite Ditomopyge sp. Gastropod Straparollus sp. Bivalve Astartella vera Cephalopod Brachycycloceras sp, Brachiopod Cleiothyridina orbicularis

    A plant in limestone?

    This one has been sitting in my "interesting but I have no clue" pile for a while. When I found it, I was splitting limestone laying in the stream. I've found that when you split limestone, immediately after splitting you'll get a couple moments of a sharp looking specimen before things start to oxidize. The limestone is a very dark gray, or almost black color. You either see black limestone or white calcite pieces while splitting. I split this particular piece open and right in the middle was a 3-4 cm long, 8 mm wide gold looking rectangle in the middle of the flat broken limestone. I thought I wouldn't get to recover it, but one hammer hit later it popped out and I was able to save it. I do find that plants in the limestone seem to get the gold or pyrite type preservation. I've found one small straight shelled cephalopod preserved like this. But overall, it's very rare here. I have maybe 3 or 4 larger pieces of what I'd called pyrite type material I've recovered. Below are some stacked microscope photos of it. The scale in the first photo is 1 mm for each mark. You can see the grain that runs left to right. This looks like wood to me, but I haven't had that confirmed before. The next two photos are a view looking from the bottom to the top of the first photo. What has me most curious are the perpendicular grain marks that are found in this area. They don't seem to just be on the outermost layer, as you can see more deeper. I'm not sure if this is some sort of perpendicular crystal pattern, or it's just the shape of the original material that was replaced with the mineral. And maximum zoom. A stack of 12 microscope images taken through the lens in the same area of the above photo. And that's it. Is this a small piece of woody material that was preserved in the sea? I wonder if vinegar would clean this up or destroy the mineral as well.

    Wilson’s Clay Pit Unknown

    I found this over the weekend at Wilson’s Clay Pit (Harpersville Fm, Pennsylvanian). I know that there are a number of strange looking rocks there that look like something but are really nothing. I ended up picking it up and keeping it because it was unique and I thought that it could maybe be something. Does anyone know what this could be? Is it just one of those rocks that look like something but is really nothing?

    Fun in Oglesby.

    Late August found me traveling to Mazon Creek for a wonderful hunt. See @RandyB's topic, Mazon Creek 8-28-21. The trip allowed a little free time to slip off and explore the road cut in Oglesby, Illinois. This is a very fossiliferous exposure and was enjoyable to explore. The fact I found shark teeth and crinoids makes me think this was a combination of Pennsylvanian La Salle Limestone unit 3 and unit 4. Even though my poor photos do not show it well, the brachiopods are very nice. But unfortunately, identification has been difficult. For those of you, like me, who enjoy geodized fossils, this formation is a great site to visit. Other brachiopods that I couldn't definitively identify. #1 #2 #3 #4 #5
  21. Hoping for confirmation and/or species identification. Thanks in advance. Not sure of much anymore with all the recent changes. Annularia inflata? Alethopteris serlii? Calamites cistii? Pecopteris? Crenulopteris? species? Pecopteris? Crenulopteris? species?
  22. While visiting in Rhode Island recently, my wife and I spent a few hours on the beach at the end of Corys Lane in Portsmouth. While it isn't one of the most productive sites I've had the pleasure of mucking around in, I always feel at home at the edge of the sea. It's a bit of a challenge to find any reasonably well-preserved fossils here, but the challenge just makes it all the more enjoyable. While my wife wandered away, deserting me once again for the lure of an ocean beach, I spread out a square of 4-mil plastic in the always futile attempt to keep the graphite-infused beach gravel off yet another pair of too-good-to-throw-away jeans. The overburden of beach-tumbled shaly gravel and slipper shells (Crepidula) was only 6-inches (15cm) deep here, blanketing a promising layer of Pennsylvanian age shale. Thankfully the tide was low and I could dig without the need to drain water out of the excavation. Regretably, I left my phone/camera in the car and have no current photos to share today, but here's one I took a few years ago: I've had mixed results here at this site, with nothing worth keeping on occasion. This day's finds were slightly above average, by my reckoning. Most of the shale I was uncovering was much too fragile to recover any recognizable plants, but after prying out and splitting a few solid slabs I did come home with some rather nice pieces, even if the preservation wasn't quite as good as I would prefer. I haven't been able to identify these seed ferns. Maybe a species of Pecopteris? The details just aren't preserved very well. The preservation is better in this harder rock. I think these are Cordaites principalis leaves. And a couple additional unknowns: The best find of the day, a modern skull, was found, of course, by my wandering wife. I believe it was formerly put to use by a sea robin (Prionotus carolinus). It was a good day.

    Mazon Creek - Cordaites or wood?

    The smaller specimen pictured opened this morning and reminded me of the larger specimen which I found earlier this year. They are very similar looking. My first thought was Cordaites borassifolius due to the linear striations, but the specimens are fragmentary and the preservation is not great so they could also just be indeterminate wood fragments. I don't think I've seen a Cordaites specimen in person before so I am not positive either way. Any thoughts are appreciated.

    Mazon Creek Unknown Plant

    I collected this specimen last year but still can't decide on an ID, it's pretty fragmentary. Any thoughts are appreciated. @bigred97 @flipper559 @stats @Nimravis @deutscheben
  25. I've spent some time gathering at the plant layer locally. I was able to pry behind the layered shale and pull out some larger pieces unbroken, and also split them. The layer is a delight, just about any piece I recover has some sort of plant impression on it. Immediately below the layered shale there is a more nodular type of rock that no longer breaks apart in neat and tidy planes. So whatever environmental change happened, it happened right at this layer. The first one was a really long and well defined fern frond. The carbon is all still in place. I want to create a parallel cut to remove this part of the specimen, then catalog and store it. I am hoping I can do so in a way that won't dust over the carbon and degrade it. The rock that covered this was a physical impression of these leaves in the rock. It appears more could be exposed at the bottom, but it's not easy to do. The second specimen is a preserved fern frond with very tiny leaves. The larger leaves stick out, but a more complete arrangement like this is very pleasing to look at. The iron staining at the bottom creates almost a work of art. This specimen has a small root or similar structure at the bottom right of the photo. There are repeating points towards the bottom with larger circular structures at the top. These huge fern leaves showed up right before I was done searching during this particular session. Both sides are shown. It would be interesting to know if it continues on in the other direction.
