  1. some more pennsylvanian plant

    Here are more stuff from the pennsylvanian shale near beijing, what calamites, Neuropteris, Cordates are abandant. I have no clue what they might be. No scales are seen.
  2. spores on leave?

    a friend of mine found this in a Pennsylvanian shale near baijing. The leave, of which the width is about 1cm(which could serve as a scale) is not well preserved and possibly of cordaites, which is very common there. We've never seen the grains like this before, of which a wild guess is some aqua-plant's spores. They are not pits as may be taken looking at the sencond pic. any ideas?
  3. Black Shale things

    Not sure what these are. There was loose shale near where I dig scattered on the ground. It had different things in it than I’m used to seeing. Maybe it was dumped from a different part of the strata, but shouldn’t be much further away. I’m not great with fish parts, are they maybe fish parts? Should I scratch them out or maybe some vinegar? There are a few other pieces that look tooth/horn shaped.
  4. Just another concretion????

    Is this just another concretion? It was listed as Dinosaur Seed Fossil Specimen, Pennsylvanian, found in Illinois. I am suspiciously thinking it's another concretion. Am I right?
  5. Pennsylvanian fertile ferns

    I recently had a split of material collected from Pennsylvanian age spoil piles in Indiana that appears to be a fragmented fertile Fern and it sparked my interest on older finds that I have yet to identify.I found a post from Roby that reminded me of a fossil that I found 7 years ago.Is this an example of Crenulopteris Mazoniana?
  6. I'm piling back in late from a fossil hunt and wanted to get this online. Found in a lower Pennsylvanian formation locally. Typically find cordaites and ferns in this formation. Today, this odd split pair caught my attention. For size reference the small calamite next to the split pair is a little over 5 cm long and 2 cm wide. Although not a great field shot I'm posting it up now in case someone can point me in a solid research direction. Part of me thinks cordaite but the unusual branching features on one side only are quite odd to me. Perhaps some sort of rhizomic structure? I will post a close-up tomorrow when I have access to natural light again. Thanks for any advice or suggestions, Kato
  7. Poteau Library

    Found this oddity while cleaning underbrush at our WPA library in Poteau, OK. The area is Pennsylvanian in age but I’m not sure this isn’t geologic or relic. Any thoughts?
  8. Going through last year's finds I found a few things that I don't recognize. All are from Pennsylvanian marine limestone. The first few all appear to be fish material of some kind. I find plenty of chondrichthyan teeth, but none of these look like any teeth I've seen, although they may be partials. Possibly some kind of bony fish scale? All images were taken under a microscope, no scale cube but they all are about 1/2" at the widest point. #1) #2)
  9. Wister Ok

    Found a couple pretty large pieces today on my property just outside Wister OK. The area is Pennsylvanian and I have found a lot of very nice calamites sp. and other plant related items but am struggling with deciding if these 2 pcs are fossils or cool looking geological, either way I will happily add them to either a collection of rock garden, depending on the outcome. Any help would be appreciated. I didn’t have a tape available so the chapstick tube is the best size reference I have for now.
  10. LARGE Conularia piece

    I found this at Wilson's clay pit in North TX. I didn't know what it was having never seen a conularia, but when I showed it to some of the members of the group I was with (Paleontological Society of Austin), they were amazed by how large it was!
  11. Got to visit one of the Pennsylvanian era sites outside of Brownwood TX with the Paleontological Society of Austin (FIELD TRIP!) and was astounded by the variety of fauna and the COLOR! Rocks in green, burgundy, purple and golds. Consequently, so were the crinoid stems! A rainbow of Crinoids! I was happy to find one little piece of an arm, also. Was hoping to find a bulb, but did not...one of the other field trippers did though! Also, lots of beautiful horn corals, bryzoans, horn corals, a big and a little Belerophon gastropod, big and little brachiopods, some neat crinoid "spikes" and what I think are Echinoid mouthplates? Aristotle's Lantern parts? Confirmation or correction please! My best find of the day was a little hash plate of echinoid spines and tiny tiny plates. I was also happy to find a cidarid plate and spine. Still looking for that whole one!! My other "big find" of the day was a Petalodus shark tooth...sadly, just the root. But it would have been a BIG one! I spent 5 hours hunting and could have easily stayed another 3 but it was a bit of a long drive home. I look forward to going out again! Rainbow crinoids: Echinoid Hash Plate: tiny piece of Crinoid arm Echinoid Mouthplates? Or Crinoid parts? Crinoid Spines: Not sure if this is another crinoid spine or something else? Petalodus tooth Root: Belerophon Gastropods Bryzoans Neospirifer Horn Corals Punctospriferer Brachiopods Fusilids?
  12. Limestone Mystery

    I'm working on my fossil limestone sink and there are a handful of fossils showing up in the polished bowl. Most are horn corals or shells, but this particular one caught my eye. It might just be a shell or something, but I figured I'd let trained eyes give it a shot. It's about 1inch long.
  13. Antiquatonia maybe? (Brachiopod)

    I think this is the genus Antiquatonia, but I’m looking for some confirmation. I found this back in April, going through my finds and trying to ID. Found in Limestone. Glenshaw Formation (Conemaugh Group)
  14. I found this strange Composita subtilita at the Paleo Site bear Kohls Ranch, Arizona. It is from the Middle Pennsylvanian Naco Formation. Does anyone know what’s going on with the strange pattern? Flip side I also should be able to provide slightly higher quality photos if needed, I just reduced the quality to be able to post several PS-I wasn’t sure if I should post this here since I have an ID, so please move it if it shouldn’t be
  15. Jumbo Orodus tooth

    This tooth came from the Finis Shale at Jacksboro Texas. That's in the Virgil Series, Cisco Group, Graham Formation, Late Pennsylvanian. It seems large for Orodus variabilis and has some extra odd protrusions on the lingual side that don't match the smaller ones I usually find. Is there another species we can find there or is this normal? @JGM
  16. Pennsylvanian mystery of Arizona!

    Hey all, last week I was visiting my grandma in Arizona, and of course I had to stop at a local fossil spot! I’m just now cleaning up everything we collected (I’ll hopefully post a trip report tonight !!!) and I revealed this little thing from the mud. I believe the brachiopods on the flip side are Derbyia crassa. If you could help me with my little mystery, I’d really appreciate it! From the Pennsylvanian Naco Formation of Arizona.
  17. Managed to stop in for a little Mazon Creek style Easter egg hunt when I was up in Chicago last June. Brought back maybe a gallon or so of concretions and I've been cycling them in my freezer (when I remember). I like to give them a bit of a (gentle) tap around the edges from time to time. This often helps the concretion to shed an outer layer or to coax a split that is nearly there and just begging to pop. As expected, I've had a number (the majority) of concretions open up to reveal a complete lack of anything at all within. The only thing that revealed itself to be of interest was this little concretion that measures 3.5 x 4.0 cm. I pulled out my copy of The Mazon Creek Fossil Fauna book and you think with that information at my fingertips that I'd be able to make a coherent guess as to the identity of this fossil but I am at a loss to match it up convincingly to any of the taxa described there. Hoping some of the members here with more experience can chime in. @Nimravis @RCFossils @stats @Mark Kmiecik
  18. Over the past year, I've become fascinated with the often bizarre fish and sharks of the Pennsylvanian. Fortunately, my home state of Illinois is a great place to hunt for such fossils. I've shared several of these in other posts before, but wanted to put everything together in one thread. Probably won't have much to post for a few months after this, but once summer rolls around, I should hopefully have plenty of new finds to share. I would say there are three major settings in which you can find fish fossils in Illinois: Mazon Creek, black shales, and limestone. I have not had luck at Mazon Creek yet, but hopefully that will change. So I'll start out with the black shales. These specimens, my first fish fossils, were collected in August 2019 from the Mecca Quarry Shale exposed at a clay quarry in Utica, IL. This shale directly overlies the Francis Creek Shale (i.e. Mazon Creek) at this location. The three specimens below are stomach ejecta from some kind of fish, and are composed mostly of partially digested fish scales. In addition, I found this very nice pair of associated acanthodian fin spines. The top fin has an area showing damage, possibly due to predation.
  19. Wister OK

    Found this item while digging around after some heavy rains eroded some channels down the hill directly behind the cabin near Wister Lake. This area is Pennsylvanian in age. Any ideas?
  20. Pennsylvanian unknown

    I found this fossil last year in the Mecca Quarry Shale (Pennsylvanian) of Illinois. I posted it previously but no definitive answer. I got a new digital microscope recently and decided to snap a few photos of this specimen up close. Hopefully they might help, though I still have no idea what it is. Thoughts?
  21. Conditions in Western PA have been unusually warm recently, with highs in the 40s and 50s. I decided to take advantage of this warm spell by getting a little bit of fossil hunting in. I decided to do a hunt focused on plants as I’ve been hunting for vertebrates for the better part of the last year and a half and, although I could never get tired of vertebrates I thought some variety was well overdue. So I headed to one of my favorite plant localities in the area. It is located in the Connellsville Sandstone of the Casselman Formation, which is in turn the upper half of the Conemaugh Group. The sandstone is around 305 million years old. The Casselman Formation holds the record of the tail end of one of the largest plant extinctions in our earths history. The prolonged wetness that had existed for much of the Pennsylvanian gave way to dryer conditions, and, as a result, the lycopsid forests fragmented. Many of these lycopsids went extinct during this event, which is known as the Carboniferous Rainforest Collapse. Conifers took advantage of these newly opened ecological niches. Their fossils have been found in this area, although I have never personally found them. Anyway, on to the fossils. Today I mostly found partial Pecopteris fronds, Neuropteris pinnules and Annularia leaflets. I’m going to include some of my better finds from other trips as well, as this trip was rather unproductive. Pictured below is the best Annularia I found today. Or Asterophyllites. I’m not sure. We’ll just go with Calamites leaves for now.
  22. Trace fossil?

    I found this in our property southeast Oklahoma. The area is Pennsylvanian in age. My first thought was that it may be weathered barite (Rose Rock) which is the state rock. However, they are Permian in age and not found in this area to my knowledge. Now I’m thinking either weathered chrinoid (calyx?) maybe a cluster of burrows, or just a really cool looking rock. Any help would be appreciated. The item is 4” x 5.5” in size.
  23. Hello from Kansas again. As I posted yesterday in the intro section, my 10yo daughter has stated an interest in fossil collecting. So, I took her out to known spot with a couple thick shale members in the lower part of the Virgilian Stage, so ~305million. We were actually searching the Stull Shale to be exact. Luckily, it had rained a decent amount a few days ago so we just examined the runoff spots. It was pretty run of the mill stuff as far as I can gather but she is really excited and wants to do more outings. I might just have created a monster... Although, there are worse things that she could bug me about. Anyway, on to her finds. I hope I have identified them correctly, feel free to correct me if I'm wrong; I do have a college degree but it has absolutely NOTHING to do with paleontology LOL. I will also post a couple that I am having problems with in the ID section. For reference, all specimens are 2-3cm in length. Crinoids Neochonetes Rhombopora Rugose coral - Most likely Lophophyllidium, or rare chance of a Caninia tip
  24. I am looking for confirmation on my IDs of these plant fossils, especially what I think is form genus Lepidophyllum. Buck Mountain No. 5 coal mine, Llewellyn Formation, Upper Pennsylvanian, Pennsylvania, USA. Scale in cm / mm. Lepidodendron sp. Lepidophyllum?
  25. Pennsylvanian disc-shaped fossil

    Hi experts, this year during one of my trips to the San Diego Canyon in northern New Mexico, I found this mystery fossil. It looked a lot like a mushroom to me, complete with radial fissures on the surface and a hint of a stalk on the backside. It is about 4cm in diameter and about 1cm thick. Any ideas? Coral? Heavily deformed bivalve? Red herring? Thanks for your input!
