  1. Receiving this gorgeous but mysterious specimen is from Upper Pennsylvanian limestone dated around 290-300 million years ago from somewhere around Kansas City. Looks like a tooth to me and my best guess would be orodus? But I have little experience with Pennsylvanian shark teeth in general and especially from this area, also cannot find a comparison elsewhere online. Any help will be appreciated.
  2. Mineral Wells, TX Fossil Finds

    Hello Fossil Friends! I recently went on a kayak camping trip on the Brazos River in North Texas and made a stop by the Mineral Wells Fossil Park. We found some incredible fossils both on the river and at the park! I was so excited about our finds that cleaning and ID'ing the fossils took priority over any cleaning and tidying up of camping gear... I started with the Mineral Wells fossils, since there were a lot of great specimens and some decent information available online about the fossils from that park. I was able to ID a lot of specimens easily (crinoids, nautiloids, bivalves, brachiopods, bryozoa, gastropods, sponges, corals and trilobites). This post contains the fossils (or what I think look like fossils!) from Mineral Wells Fossil Park that I have not been able to ID. This is my first attempt at any fossil hunting and identification, so please bear with me and I am open to any and all advice! I don't have a macro lens, so these pictures are just about as good as it's going to get. HOWEVER I would be willing to try to get more/better pictures if needed to help ID! Any assistance TFF community can give me on ID'ing these would be so greatly appreciated! Thanks in advance. Location: Mineral Wells Fossil Park, Texas Park is dated to Pennsylvanian Period, just over 300 million years ago #1 #2. It is a bit difficult in the picture to see what I think is interesting about this find... In the first (scaled) image, it looks like there may be some small bumps around a central raised area.. possible echinoid plate? #3 #4 #5. #6 #7 #8 #9 #10. This didn't clean up as well as I'd hoped, but I picked it because it looked like a closed mollusk. A piece broke off during cleaning which makes me think it may be just a rock? #11. Crinoid cirrus? Root? Maybe a small piece of stalk? #12 #13 #14 #15 #16 #17
  3. Pennsylvanian bivalve, Dunbarella?

    Bivalves always challenge me. If the ear (is that the right word?) on the left wasn't present, I would have called this Dunbarella sp. But the rounded ear doesn't match any species of Dunbarella I've seen. Maybe another genus, like Aviculopecten? Not sure. From Pennsylvanian black shale in Illinois. Thanks for any help.
  4. Fish remains?

    I feel like this is a smattering of disarticulated fish bones, but I'm not positive. The preservation is not amazing so even under magnification I'm not sure if these are bone or not. Found in Pennsylvanian black shale in Illinois. Any thoughts? @RCFossils Various levels of magnification
  5. Pennsylvanian Fern ID

    Several years ago I collected these ferns in central PA. I am currently working back through my collection making sure that everything has an identification. I have most of the identifications down, but could use some help pinpointing or confirming these identifications. Any help is greatly appreciated. Thanks! #1- ???? - I tried to tip it in the light so that it is more visible. It measures about 53mm #2- Neuropteris ovata? #3- Macroneuropteris scheuchzeri? It measures 40mm #4- Neuropteris? #5- Neuropteris on the left? I know that it is Macroneuropteris scheuchzeri on the right #6- Macroneuropteris scheuchzeri? #7- ???? - It looks like a branch with thorns
  6. Pennsylvanian Nautiloid

    This one is found in Yangquan of Shanxi, China, together with Domatoceras and Huangheceras, Pleuronautilus etc. This one has an envolute , slowly exapanding coil, with an edge on the bottom side (missing on the top side possibly due to wear and tear) . It seems to have an wavy profile, possiblely due to large nodes. any clue what it could be?
  7. Late Pennsylvanian Seed Fern

    Hi all, Here’s an interesting plant find. I discovered it in a locality in Western PA known for producing good plant fossils. I’m thinking seed fern, maybe related to Alethopteris somehow but to be honest I’m not sure what the species is. Any help would be appreciated. Thanks in advance Stratigraphy: Connelsville Sandstone of the Casselman Formation of the Conemaugh Group. Age-Late Pennsylvanian, ~305 MYA
  8. For the last 4 years I have been collecting plant fossils from sites in East Central Illinois. These fossils were all brought to the surface by underground coal mining in the first half of the 20th century. Most of the spoil piles in the area have been graded or flattened out, but a few still remain, standing tall above the flatland. One particular pile is, I believe, the source of most or all of the fossils I find. The shale that makes up the spoil has been fired by the internal heat of the pile, resulting in the hard, reddish material known as "red dog". This shale is then crushed and used as paving material, on trails, parking lots, and construction sites in the area. It's at these secondary locations that I am able to search the material for the impressions of ancient plants and collect them. The shale is pretty smashed up, so complete or large fossils are rare, but the preservation of detail is generally quite good. Geologically, the fossils come from the Energy Shale Member of the late Pennsylvanian Carbondale Formation.
  9. Bigger Brachiopods

    Found another type of Brachiopod (see below) through careful searching near Skiatook Lake. It has been harder to spot then the other 3 types of brachiopods that I have found and which this forum's members have been awesome in helping me to identify: Neospirifer dunbari. Meekella striatocoastata, and Septimyalina perattenuata. I could use help once again in identifying this type. I believe its a brachiopod and not a bivalve because it seems to have a line of symmetry from the front to the back (along the top) Notice the back has that characteristic dip in it. It definitely has been more satisfying finding this type because its bigger (up to 3 inches) and usually harder to spot as it seems to have the same color & texture as the surrounding outcrops. Has taken an hour to find one sometimes.
  10. I picked this up a while ago from the yard of a rockhound who is now deceased, but they could not tell me anything about it at the time anyway... all they could say was it was likely collected somewhere here on Vancouver Island, which would make it either Triassic Parson Bay/Sutton or Quatsino Formation, or Pennsylvanian/Permian Mt Mark or Buttle Lake Fm. I don't think it's likely to be from any of the younger formations. These structures look suspiciously like sponges to me, but I can't say for sure. They've obviously been silicified, which makes ID difficult. Any ideas? I noticed the feature marked with a red circle while looking thru the photos. It might be indicative of ID or maybe I'm just seeing things. I've not bothered to shrink the photos, as I want people to be able to see whatever detail there is on this thing. Hopefully they will load... I'll post one at a time if I have to.
  11. The KMart Display case

    All the local Kmarts went the way of the dinosaur and went extinct last year. I bought a couple display cases for $40 each. I brought it home and just a month ago filled it up with fossils. The wiring was cut from the store in a hurry, so I just left it as is. I ordered a plug and rewired it this morning. The light makes a huge difference.
  12. Folks, These photos are from a small section of shale I picked up in Northeastern Oklahoma. The shale contains marine fossils of Pennsylvanian age. I have questions about a couple of the labeled objects. I’m thinking the center one may be a brachiopod (or possibly a bryzoan--it's hard to tell because of the crinoid plate resting above it). The one on the right looks to me like a bryzoan. However, I’m a novice at identification so I’d appreciate any opinions. The putative bryzoan appears to have grown on the crinoid stem. Best wishes.
  13. A new paper is available online if you're interested: Mann, A., Gee, B.M., Pardo, J.D., Marjanović, D., Adams, G.R., Calthorpe, A.S., Maddin, H.C. and Anderson, J.S. (2020), Reassessment of historic ‘microsaurs’ from Joggins, Nova Scotia, reveals hidden diversity in the earliest amniote ecosystem. Pap Palaeontol. doi:10.1002/spp2.1316 The paper revises the 'microsaur' assemblage from Joggins, assigning 'Hylerpeton' intermedium to Tetrapoda indeterminate and resurrecting platyris as the epithet for the Asaphestera type species, while reclassifying Asaphestera as a synapsid and renaming the 'microsaur' remains previously placed in Asaphestera as a new genus and species, Steenerpeton silvae. In retrospect, Asaphestera platyris is the oldest synapsid from anywhere in North America or the world.
  14. Pennsylvanian Fossils of North Texas

    FOSSIL Roadshow Webinar 2- Pennsylvanian Fossils of North Texas https://www.youtube.com/watch?v=VXRzTzW-aVM myFossil https://www.myfossil.org https://www.youtube.com/channel/UCt18MbS9hR6BjGK6yV_aI_A Yours, Paul H.
  15. All, I wonder if someone may have an opinion about the object(s) in the small nodule shown here? The entire nodule is about 0.63 inch wide x 0.75 inch long x 0.5 inch thick (1.6 cm x 1.9 cm x 1.3 cm). It came from an area of shale that is likely of Pennsylvanian age in Northeastern Oklahoma. The shale from this location has many fossil marine invertebrates. I'm assuming its a mineral formation, but any thoughts would be appreciated. It is very hard to get the 3-D relief to show up in photos, so several angles and lighting conditions are shown. Best wishes.
  16. I don't know what to make of this?

    With the virus shutdown I've been going through my collection. I don't know what to make of this little piece just over an inch long. It appears to have spines at least on one side. I found it over a year ago in the Brownwood area of Texas from a site in the Upper Pennsylvanian Colony Creek Member of the Caddo Creek Formation. Any ideas would be appreciated. Thanks. If it isn't a fossil that's okay. I just would like to know what it is.
  17. Neat Brachiopod?

    Most of the time I see a fossil such as photo 1. When I flip it over to see the back I often get photo 2. Today I was combing with my eyes a section of water just off the lake shore in NE Oklahoma when I spotted a nice Brachiopod photo 3 ( I think it was one) When I flipped it over I was pretty shocked because the inside was almost totally clean of extra material photo 4. I don't recognize the species... but its pretty cool.
  18. Fossid ID Requested

    All, I wonder if someone could help with an ID? The fossil in the pictures is about 0.75 inch (1.9 cm) wide x 0.75 inch (1.9 cm) long. It is about 0.125 inch (0.3 cm) thick at the two large “horn-shaped” raised areas. It came from an area of marine fossils (crinoids, corals, brachiopods, bryzoans) in shale that is likely of Pennsylvanian age in Northeastern Oklahoma. The fossil seems to have two small parallel ridges running through the middle where the halves meet. Also the left and right sides are roughly symmetrical. These features make me wonder if it comes from the midline of some organism with bilateral symmetry. Any thoughts would be appreciated. Best wishes.
  19. Pennsylvanian Drift Wood?

    Just read @Bonehunter's post and discussion with @Missourian about an unknown Pennsylvanian plant and it got me wondering the same about this specimen. It looks like wood to me, but I can't find any Upper Pennsylvanian wood that looks similar. I'd love your thoughts on what it might be? I found it near where I found a large tabulate coral specimen. It's from the Bethany falls limestone group. Would that make it drift-wood? What do you think the weird textured pattern on the outside surface is? @digit guess my creek is producing more stuff I can't identify Thanks,
  20. Bivalve Brachiopod ID

    Any ideas? Found in an Eastern Kansas Limestone creek bed.
  21. Wister Ok - Pennsylvanian

    Found this items this past weekend on my property in Wister Ok. The area is Pennsylvanian and I am not sure what this is or if it is simply a cool geological piece for the flower bed.
  22. Help with another bivalve please?

    As I posted on another recent request for help on identification, I have collected and separated fossils into common groups and am working on identifying them. The area is near Skiatook lake in NE Oklahoma. This is another one that I have had trouble identifying. Any assistance would be appreciated. I am assuming this is a bivalve but not a brachiopod since no lateral mid-line(?) (not sure here). The thing that makes this so unusual is that where one side of the shell wraps around (typical), the other side sticks way out as a prominence.
  23. Pennsylvanian Aged Mystery Fossil

    This is a very odd fossil that I collected from a Pennsylvanian aged black shale site in North Central Illinois. i have been collecting this site for many years and have never found anything like it. The specimen measures approximately 3”. The site primarily consists of a Thylacocephalan type arthropod along with a variety of fish and a few nautiloids. it is very similar to the Mecca Quarry Shale of Indiana. My best guess is that it is some type of nautiloid or possibly a spiral coprolite. Any suggestions would be appreciated.
  24. Found this small (presumably fish) bone fragment last weekend while at my usual Pennsylvanian (Upper Carboniferous) limestone roadcut in northern IL. Not really sure what to make of it. It's small, not even 1cm long. My only guesses were either a partial jaw of some sort, or maybe a small fragment of a spine. Any thoughts? @jdp @Fossildude19 @deutscheben
  25. Carboniferous Trunk

    I collected this specimen at the Buildex Quarry on Highway 59 1 mile south of Ottawa, Franklin County, Kansas, USA, in March of 1970. It was dug up by a bulldozer while I was visiting the quarry one weekend. Stratigraphy: Pennsylvanian System, Virgilian Series, Douglas Group, Stranger Formation, Tonganoxie Sandstone Member, possibly overlaying the Upper Sibley coal. Age wise, is is Phanerozoic, Paleozoic, carboniferous, Upper Pennsylvanian, Gzhelian International. I found Calamites and other specimens at the same location the same day. Some were covered in carbonized material. Would very much appreciate having this identified, along with the reference or literature used to identify it, at least to the genus level if possible. I am preparing my collection for donation, so now must identify all this stuff that I haven't identified before! Thanks!!
