  1. 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.
  2. 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.
  3. 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)
  4. 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 with @jdp about this and will most likely be donating the most important ones to the Carnegie Museum of Natural History. If any of my IDs seem strange or wrong please let me know, I am always learning and value new info. I guess I’ll start with the marine invertebrates. To start out we can start small, with brachiopods, cephalopods and horn corals. The first is a Linoproductus from the Ames Limestone, a classic Pittsburgh marine zone.
  5. Fossils of Parks Township

    https://fossil.15656.com/ Here is my personal website that targets fossils I have found locally. I try to post articles about particular finds, especially when it highlights a new genus or species for me, or a better specimen than I had before. I am highly interested in providing content for people searching online to find, especially about local specimens. I do my best to photograph each specimen to maximize detail and to satisfy curiosity. In keeping finds organized, I keep a catalog page and created a local numbering system: https://fossil.15656.com/about/fossil-catalog/ As I read research papers, I tend to post links to them and add commentary. https://fossil.15656.com/about/research/ I've done my best to provide a description of the local geology here: https://fossil.15656.com/local-geology/ And as I find interesting things along the way, sometimes I will create a live research article as I learn about it. Example: https://fossil.15656.com/research-pages/fedexia-striegeli/ I've only been collecting fossils for a year at this point. I'm still overwhelmed with how much there is to learn about fossil taxonomy and geology in general. This is a relaxing hobby for me that keeps me excited with the thrill of discovery. Thank you! Clint
  6. Odontopteris perhaps? Fern / Plant

    I think this is Odontopteris. The flat leaf tips are what have me thinking that. I have lots of local shale that I can pull these from readily, but maybe once or twice over an hour I can pull one this size out. Any fern experts here able to validate? Attaching a couple fossil plates that I use to identify local ferns.
  7. Petalodous Teeth

    To date, I've found 4 teeth, all in the same general area. One is shallow, the others are a big longer. The 3rd is a bit broken, I don't think I have a photo online right now of it. All are attached firmly to the limestone and I don't have any hope of ever getting them out clean. 1st Tooth: 2nd Tooth: 3rd Tooth No photos of this one. Sorry I promised 4 teeth, sadly only photos of three. 4th Tooth:
  8. Carboniferous Limestone

    This piece of limestone looked like sea shells (clams or brachiopods) at first glance. However it’s one bumpy continuous surface. Any idea? The rock would be around 305 million years old. The rock broke easily along this surface which made it easy to see. Shells typically show white preserved Agagonite on them as well. No such preservation on this surface. Rock from Western Pennsylvania, United States. The surface is wet. Ruler is in inches.
  9. Late Carboniferous Oyster or Clam II

    A second large Clam or Oyster? I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer so that I could actually pick pieces up. After the heat this weekend, they were easy to pick apart once I got them home. Yesterday, I found the first piece. This is the one I found today. When it came out of the rock I was a bit shocked at how large it was. I carefully tapped around the specimen and was able to remove most of the surrounding rock carefully. This is the larger of the two pieces I found this weekend. I have less confidence in identifying it as has less features than the first piece. You can see shell material flaking off in the 3rd and 4th photos below. The fossil after I found it: Then, once I removed it from the rock:
  10. Late Carboniferous Oyster or Clam

    I love and hate finding large fossils. They are really interesting and striking to look at, but I have a hard time getting an ID on them. I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer. After the heat this weekend, they were easy to pick apart. Yesterday, out popped this piece. There is another one I found today that I will be posting after this one. This piece has several wavy ridges. The shell material looks pearly, and perhaps some calcite replacement has happened. There was a piece of shell stuck on the mold portion as well. I'm seeing about 6 distinct ridges. Anyone know what it might be? Before I removed it from the rock: Several views after removing, trying to show the ridges:
  11. Long shot micro fossils

    Two mystery mini fossils. I’ll include scale photos, with marks at 1/2 mm. I’m on the lookout for Carboniferous Trilobites, and examples I’ve seen are very tiny in this formation, no more than 1/2 inch long.
  12. Worthenia perhaps

    While working on a specimen, this little gastropod fell out. Its measures about 7mm wide. Is it a Worthenia or something else? Being so small, I'm not sure it looks like the classic examples I find on fossil plates. Ruler is in mm. Found in the Glenshaw Formation. Pennsylvanian in age.
  13. One of my first exciting finds was a piece that looked like a tooth back in March. Turned out to likely be just a cool shaped rock. Fast forward 3 months and I finally found this today, which I believe is an actual tooth. But I'm no expert, is my identification correct?
  14. Carboniferous Gastropod

    Found this piece in the same piece of limestone that my last questionable piece was in. It's a Gastropod for sure. It was split within two separate planes of rock. There wasn't any detail within the split, so I just glued the two pieces back together. I've found lots of gastropods in limestone, but they are usually really tiny. This one was a full size for once. Glued back together using Paraloid B-72. As close as I can say, this limestone is approximately 305 million years old. I've considered both Donaldina and Meekospira. Last Questionable Piece:
  15. Big clam?

    This thing is big, much bigger than clams and brachiopods I usually find. I haven’t attempted to remove it yet, because things this size usually break up when chipped out. I see shell material and some ridges in the steinkern. Excuse my clean hammer.
  16. I am nearly sure the top piece is Metacoceras. The middle is a clam, but what species? Perhaps Astartella concentrica? The bottom, what is that thing? 6477/6478 show it in detail. I find these a lot. Are they brachiopods? Not shown, but there is a horn coral on the back of the piece in a cross section.
  17. Wilkingia Sp.?

    Not my best photos, but a quick dimensional Wilkingia that I found over the weekend. Identification is likely but not solid.
  18. Fenestella? Bryozoa of some type?

    Tonight I found a new limestone ledge sitting 6 inches from a stream water level. My father and I started hammering away at the shallow edges and removed a ton of interesting specimens. While there were some nice cephalopods, lots of brachiopods and clams, this piece caught my eye. I’ve read about Bryozoa and I’ve seen similar things on fossil plates. I believe I remember seeing pieces of them in limestone while digging, but never anything big. So, is it a Fenestella? Or something else? I’ve never found one worth showing. I saw a species list for it and it is very long.
  19. A few Pseudorthoceras

    Pseudorthoceras is a bit of a mystery locally for me still. They are probably the most common straight shelled cephalopod I find. I also found at least one Mooreoceras. From what I understand, Mooreoceras and Pseudorthoceras are both classified under the Pseudorthoceratidae Family
  20. Mooreoceras sp.? or something else?

    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.
  21. 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.
  22. Brachiopod?

    This one showed up after a rock split. The steinkern was really shiny and smooth. Usually the shell is hard to save, but I was able to when air chiseling away at this one. There are noticeable grooves on one side.
  23. 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
  24. Pennsylvanian Clam?

    Found this one in the eroded limestone. It came out in two pieces. I believe it to be a clam. You can see it dimensionaly through the top. I'm still going to clean it up further.
  25. Metacoceras?

    Found this in what I call limestone locally, but it is more of a sandstone/shale mix. Very hard, black and cement like. Squares are 1 inch. I air scribed it out of the rock, where 50% was showing. My layer specifically is Woods Run Marine Zone, a hundred or so feet below Ames Limestone. It is the Glenshaw Formation. I am in Western PA. Also, this is my first forum post. I have several other types to post, but I figured I would start with this.
