    Pennsylvanian Tooth Fragment?

    Found what looks like a tooth fragment last week. I've only ever found Petalodus teeth in this formation and it doesn't quite look like those. There are no serrations on the fragment. This was found in Allegheny County, PA, is from the Glenshaw Formation and is probably out of the Brush Creek Limestone.Thanks for the help.

    Pyrite Plants--Gold and Green

    Last week I was hunting in my usual location in Allegheny County Pennsylvania (Glenshaw Formation) and found that several of my specimens have splotches of what appears to be pyrite crystals. With some of the broken fossils I could see that even the insides contained gold-colored pyrite. On the other side of these plates were what looked like rootlets covered in a pale green mineral. Is this pale green mineral pyrite as well? Is there some way I could test this? Thanks for the help.

    Pennsylvanian Marine and Plants

    Howdy! I'm finding some beautiful stuff digging in the Glenshaw Formation of Allegheny and Beaver counties. Hoping to find out/confirm what they are. The limestone finds I believe are from the Brush Creek Limestone. As usual, all help is greatly appreciated, thanks! Side view of Wilkingia? Never saw round leaves before Spiropteris? Sigillaria bark? Some sort of bone or root of a Petalodus tooth?

    Glenshaw Formation Unknown

    I found this piece in my back yard a couple of years back and I still don't know what it is. It is Pennsylvanian, Glenshaw Formation and from Allegheny County, Pennsylvania. Thanks in advance for all help.
  5. Hello, found what I think are nautiloids and brachiopods. I found the rock in a stream and I can't say what limestone (maybe brush creek or pine creek), but the area is Glenshaw Formation in northern Allegheny County, Pennsylvania. It's quite difficult for me to get good pictures, let alone good pictures with scale, so I'll tell you that the first two pictures are 2 cm (same organism), the second is 5.5 cm and the largest Nautilus in the last pictures is about 6 cm. All information is appreciated, thanks!

    Pennsylvanian Brachiopod Bi-Valve?

    Howdy! Found this little critter today in Allegheny county, Pennsylvania. It is Pennsylvanian, Glenshaw Formation, probably Brush Creek Limestone. It's a bit different from the ones I'm used to finding and I don't see anything similar in my guides. It is approximately 1.75 cm x 1.25 cm. Even if it can't be ID'd I'd appreciate it if someone could tell me if it's brachiopod or bi-valve. Thanks in advance.

    Carboniferous Bark, Roots, Stems?

    I was rooting around in Ambridge, Pennsylvania, Beaver County yesterday and found some interesting plant fossils. They are Pennsylvanian and out of the Glenshaw Formation. Not sure if they're identifiable or if I would need a microscope to ID. Any help is appreciated.
  8. Hello all. I am posting a link to a calendar I created for 2023. It showcases twelve different late Paleozoic gastropods I have recovered over the past three years in Armstrong County, Pennsylvania. Eleven of them are from the Pine Creek limestone, and one other comes from the Brush Creek limestone. Each month features a different gastropod, photographed after coating it using ammonium chloride vapor, using an iPhone to capture photos through a microscope lens. The cover photo showcases all twelve, and the images for each month typically showcase an additional view at a much larger size. While this is a color print calendar, all the content throughout is black & white. If you enjoy natural color photos of fossils, you might skip this. I am selling this calendar without profit to me. I am still waiting to receive my copy, and I can follow up on print quality when I get mine. Lulu says this is 100 lb paper, but I'm still determining what to expect. Please PM me for purchase information.

    Pennsylvanian Fern ID

    Hello! I have a few dozen plant fossils for ID. I'm going to go one at a time, but if you'd like to see them all, please go to the Members Collections section of the site with the link below. There feel free to offer corrections, specifications or confirmations. All are from the Glenshaw Formation. This first fossil looks like Pecopteris arborescens to me. What do you think?

    What is this stuff?

    One of my local spots to fossil hunt has a lot of limestone (I think) with what looks like worms running through it. I see this stuff everywhere and have no idea what it is. The area is definitely Glenshaw Formation and has fossiliferous limestone and shale. Any help is appreciated.
  12. Howdy! Pried what looks like a branch out of some shale today. I was hoping someone could confirm for me that this is petrified wood and possibly ID it. Lots of tree fern leaves and stems in the area. Additionally, the fossil seems unusually heavy. Thanks in advance! Pennsylvanian Glenshaw Formation.
  13. Lucid_Bot

    I Doubt this is Identifiable, but,

    What do I know? This piece is Pennsylvanian and probably from Brush Creek Limestone. It was found near marine fossils. I have no idea what it is. All help is appreciated.

    Pennsylvanian Brachiopods

    Howdy! Split some limestone (I think it's Brush Creek) to find dozens of poorly preserved brachiopods and now I need some help IDing. Thanks in advance for any help. @cngodles

    Kasimovian Goniatitid

    I've had this for quite some time, I thought it may have been a gastropod. But I'm now very convinced I have an ammonoid. They are very rare over my way, they didn't like coming into the geologically temporary shallow sea bays that formed. We have many Nautiloids, but not many Goniatitids. I've considered Pennoceras and Mangeroceras. The former is reported from rocks of similar age in Ohio, but the shell ornament has me considering the latter. The growth lines curve back towards the posterior at the dorsal-lateral shoulders. Anyone from the mid-continent (who are swimming in ammonoids at places) have a good ID for this one? Scale bar = 5 mm. Conemaugh Group Glenshaw Formation Brush Creek limestone
  16. I'm chipping away at what I think is brush creek limestone to find what I think is Mooreoceras (first two pics) and Metacoceras. I have no idea what the last fossil is. All help is appreciated, thank you.

    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.

    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.

    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.

    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.
  22. 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 bottom of both photos is in millimeters. Maybe it's just a shashed up Petalodus tooth root. Have any of the Carboniferous shark tooth hunters perhaps seen something similar? This second photo is a closer look at the raised areas. There is a lot of matrix infill here, so again, it will probably be difficult to identify. At the very least, I'll stick the pieces in a box and file it under mystery fish parts.
  23. 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.)
  25. 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 or tooth experts here? Perhaps this matches something that someone has seen. The connection at the junction where it turns into a point is interesting to me. Much more detail:
