    Late Pennsylvanian Fish Tooth

    Whatever this fish tooth is, I've never found one before. I had a small sliver showing in a rock and spent over an hour slowly air scribing over it and getting it to this point. I'm hesitant to go much further, as I may break it. I considered Polyacrodus for the shape, but I see none with the pitted pattern that this has. Tired of trying to ID Pennsylvanian fish teeth yet, @connorp? Maybe this is another paver type teeth from a ray, etc. For scale, the length of the tooth in the first photo is 13 mm.

    Five Holes in an Arch

    Found this the other day in what I think is brush creek limestone. The area is Glenshaw Formation, Carboniferous (Pennsylvanian). All help is appreciated.

    Pennsylvanian Snails and Clams?

    Hello again, I found these tiny specimens today, and I'm not quite sure what they are. If I had to guess, I'd say the spiral shelled creature is Amphiscapha and the more clamish one looks a bit like Kozlowskia without the little side wings. No idea what the last one is. As always, all help is greatly appreciated. Also, sorry about the bad pics, these are quite small specimens.

    Pennsylvanian Marine Fossil?

    Howdy! Chiseled this out of a rock today. I thought it was a coral at first, but not quite sure now. The final picture is a cross section of the inside. Thanks in advance.
  5. I am going to start adding some images of my favorite finds which I call Collection Pieces. Identifications range from maybe, probably to most likely. I've only started to seriously collect over the past year. I've spent a great deal of time studying and learning Geology, as a hobby. I am located in Western Pennsylvania. At first, a map of the area. Anything in bright yellow is the Glenshaw Formation. The Ames Limestone layer exists between the Glenshaw and the Casselman Formations, which is the Orange color on the map. I have yet to explore the Ames Limestone, so I've only found f

    Late Pennsylvanian Stigmaria ?

    I’m thinking this is Stigmaria. Scale bar = 1 cm. Found in the shale below the Brush Creek limestone, a zone with many plants.

    Pentagon shaped piece

    When cleaning up rocks I brought home today, I found this little piece that I didn't originally target. It's pentagon shape makes me believe it's for sure a fossil. I've never found anything like it, so I feel like I'm about to get an education here. Perhaps part of a crinoid? Whatever it is, I don't have the experience, yet. Also noticed the indented hole on the top. Maybe part of it, maybe not. It's way too centered I think to not be part of it. Underside. It is convex with a small raised ridge along the edge. Sideways view of the
  8. I don't expect this one to be easily solvable. I've found nearly two dozen Petalodus teeth over time, so I have a good idea of what the cross section looks like for the tooth material. The white edges with the canals reaching inward. You can't see it will in the photo but there is a calcite grain structure in the center. This piece was oddly shaped and fragile. It's unlike any of the surrounding rock. There are 4 pieces in all, but this one has the best look. The lumps at the bottom edge are raised and textured like the surface of some teeth are. The scale along the bot

    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 limeston
  10. Howdy! Just posting some of my finds for ID. Feel free to correct or specify. I can provide dimensions if needed as it's hard to get good pics with a measure of some of these. The first two look like Asterophyllites to me. The third, fourth and fifth, I'd guess Sphenopteroids (the fourth is only 1 cm from top to bottom). The sixth I think is Annularia. The rest I believe are Neuropteroids.

    Pennsylvanian Bone or Just Stone?

    I found this on the bank of a stream near Pittsburgh. It looks to me like bone, but perhaps I'm imagining things. It's rather light and I can tell you the stream is part of the Conemaugh Group, Glenshaw Formation and Pennsylvanian/Carboniferous period. Any help is appreciated. (Last pic has the scale.)
  12. Hopefully I'm not breaking any rules here posting a link. I spent my weekend finally putting my catalog into a proper database, and creating a user interface for it. I used to use Google Sheets, which is pretty great. If I wanted to, I could use them as the source of data, but I decided to create a proper MYSQL database so I can keep relationships across tables, such as the stratigraphy of particular find locations. I have many more improvements coming for it, but it is at least functional right now. Everything from CG-0001 to CG-0161 is from the Glenshaw Formation, Conemaugh Group

    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)

    Brachiopod, but which one?

    By far the most detailed Brachiopod I’ve found to date. The top impression, which isn’t shown, appeared to have two larger bands running down the center. The small piece in attachment 3 was somewhat of a steinkern or impression below it. Scale line is 1cm. Photos taken with a DSL through a microscope. This came from eroded Limestone.

    Late Carboniferous Gastropod

    Possible ID of Trepospira sphaerulata from a local gastropod expert, but he isn’t sure. Similar ones in a group with original specimen at the right. Left is suspect of being related, but it might be.
  16. Hello all. Quite a time back I found this shiny black thing in a piece of Brush Creek limestone. I had tentatively identified it as a trilobite free cheek part. However, a trip to the museum has the invertebrate paleontology department telling me that it's not for two reasons. While similar looking as a free cheek, the top portion doesn't match It's way too big to be a trilobite from this time period. I do agree with both assessments. It's twice the size of a typical Kasimovian (Late Pennsylvanian) trilobite from here. So, any fish part

    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.
  18. 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.
  19. 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 cu
  20. I'm getting better with plants, but I haven't really found anything that says seed or spore pod to me. This one finally does. It's a small depression with texture. I wish I had the other side, but I didn't see it. This was from a layer with many ferns, Calamites, and Cordaites. Concretions are about non-existent here. In fact, there may be none at all. It's the texture in the depression that has me thinking seed pod mold.
  21. Hi. The geological info for this find is: Pennsylvanian (Carboniferous), Conemaugh Group, Glenshaw Formation. I've been digging at an outcrop near a local stream and finding a lot of pecopteroids, neuropteroids, calamites, some sphenopteroids and possibly lepidodendron/stigmaria, sigillaria and cordaites. Recently the rain washed away the dirt at the base of this outcrop. Cutting away the rock at the base I found at least a dozen instances of these somewhat cylindrical and flat-topped and flat-bottomed rocks sitting one on top of the other. The first picture shows a cavity from which I removed

    Unusual Carboniferous Plant Fossil

    Howdy! This specimen comes from the Pennsylvanian Period, Conemaugh Group, Glenshaw Formation, in the Mason Shales below Brush Creek Limestone. The area has a lot of Pecopteroids, Neuropteroids and Calamites. However, I've been informed that it is not Calamites. I should also note that this piece was part of a larger fossil cast that was crumbling apart when I found it, and unfortunately, I was unable to save the rest of it. The last picture is the back side. All help is appreciated and thanks in advance!

    My Best Carboniferous Finds

    Hi all, I’ve posted a few topics on the forum but have yet to show my entire collection, or my best finds. So here goes. A little background on me. I’ve been fossil hunting since I was very young, probably since I was 4 when I found a plant fossil in my backyard. Over the past few years as I have ventured into adulthood I have gotten very interested in the fossils of the Pittsburgh area. I will display my best finds here and periodically update the thread with new finds. As a note, many of the vertebrate fossils I have found are rare and may be important to science. I have been in contact

    Pennsylvanian Ammonoid

    I found this a while back, but finally saw it as an Ammonoid. But which one I wonder. It is pretty thin. Unseen is the inner umbilical groove, but it’s likely not important for ID. Opposite side is unremarkable.
  25. I found this oddity today while examining some fine grained finds. This is basically soft limestone, where the rock is pretty soft and most of the calcite has been dissolved. I forgot to include a scale, but if I were to guess, it's about 1/2" across the structure (12.7mm). I plan on measuring again. There were several of these throughout the piece, but this was the most prominent. My guess is some sort of Bryozoan.
