  1. I saw a post on facebook that someone was looking to get rid of some fossils they had collected locally so I arranged to meet up this afternoon. Most of what was being offered were carboniferous fossil ferns from St Clair and they had some beautiful examples from the site that has been closed to collecting for several years now.
  2. L.S., Pecopterid fossils from the Piesberg (Lower Saxony, DEU) are notoriously difficult to ID because the preservation does usually not show the venation (e.g., Josten 1991; PDFs of text and atlas volume). As a group, the pecopterids have also undergone quite substantial taxonomical revisions in the last few years based on material from other localities; not in the least from Mazon Creek (Illinois, USA). This makes identification of my Piesberg-pecopteris a rather daunting endeavour. Perhaps someone on TFF who has experience with the Mazon Creek pecopterids and most current nomenclatural changes would be willing to take a stab at them for me? Images can be enlarged by clicking on them. If photos of specific details are required, let me know and I'll do my best to provide them (but note that venation is often simply not preserved very well). Thanks in advance for any ID suggestions or tips you can provide. Kind regards, Tim Specimens TKTW0048 (left; "Spiropteris sp.") and TKTW0049 (right) Specimen TKTW0542 Specimen TKTW0651 - I'm not even sure this is a pecopterid... Specimen TKTW0826 (left) and TKTW0827 (right) Specimen TKTW1004 Specimen TKTW1078 (left), TKTW1079 (middle) and TKTW1082 (right) - all from same slab of rock (related?) Specimen TKTW1099 - "Spiropteris sp." but what kind of pecopterid is in the foreground? Specimen TKTW1099 - note fertile pinna on the right
  3. Hello to all. Found this sample few years ago. Place of discovery: Ukraine, Donetsk region, Dobropolsky district. The age of it is the Kasimovian stage of the Carboniferous period (307 Ma). Have a nice day 3.mp4 6.mp4

    Fossil Sites in Western PA?

    Greetings, I’ve recently gotten back into prospecting fossils and I’m looking for some suggestions on sites to visit in western Pennsylvania. I frequently visit Ambridge PA to find fern and Calamite fossils from the Mahoning fm and would like to find more. I also would like to find fossils of early Permian (tetrapods, plants, or invertebrates). I hear that Washington county (south of Pittsburgh) has some great spots and would like to know if it were true. I also would like to show some of my findings from Ambridge as well. Note: I’d like this to be suggested places not just western PA but West Virginia and eastern Ohio as well.

    Stigmaria blob

    Howdy all, I have reason to suspect that this is a heavily crushed stigmaria I found while fossil hunting today. I was in the mammoth cave region of Kentucky in a creek where I found plates of coal up to two feet long as well as this fossil. I also went down into an exposed lake bed of Nolin lake which was down the hill from the site I was at and found several of what I'm guessing are mississippian crinoids.
  6. I have a fossil fern (seed fern?) from Kentucky for which I have finally been able to acquire readable close ups of the leaf structure. Members of the Forum have previously been very generous with their advice; however the image was not sufficiently detailed in order to make more definitive suggestions. Various suggestions are that it is possibly a cyclopteris, a neuropteris ovata, or a macroneuropteris scheuchzeri specimen. However, the leaf structure appears to be more robust than images of these types of fossils. With the closeups hopefully a more definitive answer can be found. Suggestions are welcome. The 1st image is of the entire specimen including a neuropteris leaf (disregard the cyclopteris label). The fossil of interest is in the upper right. The remaining images are closeups. Thank you in advance for any suggestions.

  8. Hello! I have this iridescent Petalodus tooth that I would like to preserve. Firstly, it has a severe crack though the matrix (see pictures). Secondly, is there anything that I should do with the tooth itself? What are my options? I appreciate your help.
  9. I’ve been air scribing this piece out and I figured it was a Mooreoceras. However, the ridge going up the front is something I haven’t seen on this species. Is it just squashed a bit? It’s a pointed oval in shape. The length is nearly 3 inches.
  10. Yesterday, I spent about 30-45 minutes sitting in a pile of mud/rocks and practicing breaking apart softer rocks with a hammer and chisel (a little closer to shale--pretty easy to split into layers--but I'm not sure?) to see what I could find. This was one of the prettiest things I found! Northeast Alabama, US. Pottsville Formation. Thank you for your patience with my lack of knowledge. I'm currently waiting for a paycheck so I can purchase a book that will hopefully decrease my posts here!
  11. 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 fossils that exist in the marine zones below the Ames. Second and Third, are Metacoceras. The Fourth photo is of another Metacoceras. The id is slightly less likely as I can only see a few of the rounded spines. But I'm pretty sure it is one. Coming up next is a Mooreoceras that I found just this past weekend. I maintain everything on a website, that is listed in my profile. Thank you! Clint
  12. I am attaching images of Pennsylvanian seed ferns that were identified by the collectors. The fossils from Kentucky were generally found in the shale around closed down coal mines on family farms. Hopefully these images may assist others in identifying their specimens. Comments/suggestions/corrections are welcome and I also would appreciate specimen identification beyond the genus level for many of the specimens. The first image is of a Pennsylvanian alethopteris specimen from eastern Kentucky: Pennsylvanian alethopteris from eastern Kentucky. Pennsylvanian cyclopteris (upper right) and macroneuropteris specimens from eastern Kentucky. Pennsylvanian eusphenopteris specimen from eastern Kentucky. Pennsylvanian mariopteris specimen from eastern Kentucky. Pennsylvanian Pecopteris plumosa specimen from Upper Silesia in Poland. Pennsylvanian pecopteris specimen from eastern Kentucky. Pennsylvanian sphenopteris specimen from eastern Kentucky. Pennsylvanian crenulopteris specimen from Mazon Creek, Illinois. A helpful Forum member suggested this could be crenulopteris acadica. This last Pennsylvanian specimen is from Mazon Creek, Illinois identified by one individual as Lobatopteris lamuriana and in addition a helpful Forum member suggested that it is possibly a diplazites unita.
  13. I have 4 Pennsylvanian stigmaria specimens of which only one was specifically identified as a lepidodendron by the collector. I am hopeful that others might have useful suggestions in terms of better identifying the others. The 1st image is of a Pennsylvanian lepidodendron stigmaria specimen from Kentucky. This is my nicest one because not only is it better identified, it also illustrates rootlets and buttons. Image 2 is of another Pennsylvanian stigmaria from Clintonville, Pennsylvania. This appears to be the most common type of stigmaria that I have seen. Would anyone have suggestion/possibilities that would better characterize this specimen? Images 3 and 4 are a Pennsylvanian stigmaria with a heavily degraded label. Image 4 is a closeup of the specimen in image 3. I was able to decipher parts of the label and it was apparently collected near Middlesboro, Kentucky. The rootlet scars on this specimen are much less three dimensional that the rootlet scars on the specimen in image 2. There may be a comment on the label about the rootlet scars having a spiral character. Would anyone be better able to characterize this specimen? Image 5 is of another Pennsylvanian stigmaria from Kentucky. It has many similarities with the specimen depicted in image 2. I also have one very heavily weathered stigmaria from Oklahoma that is very similar to the ones depicted in images 2 and 5; I didn't think it was worth uploading an image. Comments and suggestions about the others would be appreciated.

    Carboniferous Worm?

    Hello, I found what looks like a worm on a block of limestone too large for me to split. So I took a picture of it. It is about 4 cm. The limestone is Carboniferous, Pennsylvanian and from the Glenshaw Formation. Thanks for the help!
  15. I am attaching images of calamite and annularius specimens in my collection. Because their appears to be some debate among the experts on the relationships between calamites and sphenophyllum and asterophylloides, I am also including images of these specimens. I would welcome comments, suggestions or corrections from viewers. Further species identification would also be appreciated. Image 1 is of a Mesocalamite specimen that was among other Pennsylvanian fossils from Kentucky. Image 2 is of another Pennsylvanian Calamites from Kentucky. Image 3 is of a Pennsylvanian Calamites specimen from Alabama. Images 4 and 5 are Pennsylvanian Annularia leaf specimens from Mazon Creek IL. Image 6 is a Pennsylvanian Annularia radiata specimen from the Westwalian A & B, Lower Silesian in Poland. The contrast between the fossil and the underlying rock is so poor that I did alter the exposure settings in order to better view the fossil. Image 7 is of a Pennsylvanian Sphenophyllum specimen from Mazon Creek IL. Image 8 is of a Pennsylvanian Sphenophyllum cuneifolium specimen from the Westwalian A & B, Baszkirian, Lower Silesian in Poland. Again, because the contrast was so poor, I altered the exposure in an effort to obtain a better picture. Image 9 is of a Pennsylvanian Asterophylloides specimen from eastern Kentucky.
  16. I have 2 Pennsylvanian fossils from Mazon Creek. They have previously been identified as crenulopteris and lobatopteris lamuriana. Presumably the crenulopteris specimen is a seed fern; however, I am unsure about the lobatopteris lamuriana specimen. Presumably the lobatopteris was once labeled as a pecopteris so is it still considered to be a seed fern? Any information or suggestions would be greatly appreciated. The first image is of the lobatopteris specimen, The next image is of the crenulopteris specimen.

    Anyone able to ID please? Thanks

    Hi, At Trefil quarry, Wales, I found these. They were found very close to one another. This site was a carboniferous coral reef. If anyone can ID, or point me in the right direction, it'd be much appreciated. Thanks!
  18. Hello to all. Found this sample few years ago. Place of discovery: Ukraine, Donetsk region, Dobropolsky district. The age of it is the Kasimovian stage of the Carboniferous period (307 Ma). Have a nice day
