    Leighton Formation Conodont?

    So, I have just found this highly-suspect fossil - my guess is a conodont. I saw it as I was examining pieces of shale, and thought it was worth looking at under the microscope. It seems to have the diagnostic features, even the transition of colors between the blue base and white tips. I was hoping for some of your options on it. If this is a conodont, it would be the first from this formation. My guess would be a Ozarkadina sp - it is a very common Silurian conodont here, and some of the elements look remarkably similar to my specimen. This specimen came from the very fossilifer
  2. Good evening again!. Amazing what you can find jut scanning shale after shale! I find multiple clusters of conodont segments and denticles but tonight's find is potentially very exciting!. Surrounding the elements is a finely granular, uniform, brown matrix which is not shale (arrow) and not sediment (at least my thought . I see this on occasion in shale but this is the first time I've found it uniformly surrounding conodonts. to me it appears organic. Thoughts? thanks so much again!!! Bone

    Pennsylvania microurchin?

    I put this on the general forum as well, but this is probably more appropriate!! In my search for conodonts in Pennsylvanian stark shale (between Winterset and Bethany falls limestone) I routinely find concretions/nodules-most are powdery but sometimes i find teeth and other microfossils. Well much to my surprise, upon splitting my thousanth shale, I found a 1cm nodule, and within it, this apparent micro sea urchin-one of two in the nodule. From spine to spine (7:00-1:00) it measures just under 2mm in diameter I am refining my photog techniques with a newly purchased leica M420,
  4. I finally got some microfossil slides and I got some additional Devonian matrix from New York. I decided to go back to the Genundewa Limestone matrix primarily because I failed to find shark related matrix from other locations that are of the same age. Each of the three searches in this matrix has produced different results which make it fun to search. This search was a lot of Phoebodus teeth and some were close to 75% complete. Easily the best Phoebodus teeth I’ve found in this formation yet. I found a fair amount of Omalodus teeth and some nice ones. I also found two incomplete

    Idiognathodus P1 element?

    I'm hazarding a guess as a P1 element of Idiognathodus?, or is it something else? seems a little wide for a conodont? Pennsylvania stark shale. Yeah or neigh? Thanks! Bone

    Conodont element?

    Fossil forum, I just uncovered this possible fossil. It is from the Leighton Fm. To be honest, I am not sure it is actually a fossil, but I wanted to check. I was thinking that it could be a conodont element, but am unsure. Any help on its id would be helpful. Here are some pictures of it:

    The dreaded chordate: Conodonta

    If you haven't read my 'about' on my profile, then... What are you doing? I'm the best person on this forum, duh, you should've memorised it by now(!) Jokes aside, I love conodonts. The gorgeous little extinct wigglers that resemble eels... They're so common, that they're used as index fossils. What does that mean? People identify the age of fossils, based on conodont elements found with them... That's crazy! How does this work? Well, evolution changes animals over time, as you'll know, which means, due to the abundance, and date range of the specimen, you can work out age of sedi

    Home Conodont Extraction

    So, in trying to identify my local limestone for sure, I've gotten the need to try to extract conodonts, and I'd for sure like to see other microfossils. I know this has been discussed here before, but I was wondering what might be the correct or tried and tested method for home, using obtainable chemicals. The last thread I found was talking about lab processes and clouds of white smoke. I've heard different things from using acids (Vinegar), Hydrogen Peroxide (3% limit at Walmart), to Kerosene. Also a need for sieves, filters, etc. Curious for a guide or advice for ef
  9. Time Period: Pennsylvanian Location: Missouri Formation: Most likely Winterset limestone Hello! I am currently puzzled on weather or not this is a Conodont or some fragments from Brachiopod. I am thinking it could be broken parts of a shell or broken pieces of a Brachiopods fossilized lophophore supports from a very small specimen! I have not found any conodont specimens from this location yet as I usually do not hunt for them Images in natural file size: https://imgur.com/a/KNeq
  10. Hi everyone I think I just found a new hobby With my latest fossil delivery I recieved quite a lot of microfossils & matrix vials as the world of microfossils was something that I have been long interested in. So a 2 weeks ago I finally ordered my first microfossils for which I reserved a special drawer in my archive cabinet. So here is a recapp of what I all got: 3 vials of permian material from Waurika, Oklahoma 1 vial of permian material from The red beds of Archer County, Texas 1 small vial of Conodont rich Mississippian material from the Chappel Limestone fo
  11. https://phys.org/news/2020-11-paleontologists-identical-evolution-isolated.html Paleontologists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the University of Calgary in Canada have provided new proof of parallel evolution: conodonts, early vertebrates from the Permian period, adapted to new habitats in almost identical ways despite living in different geographical regions. The researchers were able to prove that this was the case using fossil teeth found in different geographical locations. A scanning electron microscope image of a dental platform elem

    Harding sandstone question

    Hi guys, I recently purchased some processed Harding sandstone, I was looking for unprocessed stuff but I could not find any for sale so I had to just go with this. The fossils arrived today and I have been examining them with my microscope, I find this stuff very fascinating. My question is regarding these fossils here: the ID guide that came with them claims they are sharks but I find this strange, I believe chondrichthyes only appeared in the Late Silurian so how could this be? Are they something else, and if so do we know what that something would be? Also if the

    Oddly shaped bone in pebble from Cap Gris Nez

    Hi all, Found this pebble on the beach close to Audresselles (Cap Gris Nez area, Boulonnais) amidst the heavy rain and wind yesterday. Initially, I thought it was just a piece of odd-looking fossilised plant-material, with a faint thought in the back of my mind that may be it could be a fish skull. When I checked it this morning, I was able to confirm the piece is smooth on the outside, and seems to have what appears to be bone fibres on the inside. In other words, I'm convinced now that it actually is bone, though still have no idea what kind...

    Conodont help

    Hi all! Hope everyone is healthy and Covid free! Been focused on conodonts now and need help with these two- found in Stark shale member between Bethany Falls limestone and Winterset, if I have that correct :), Stark shale for sure though. The first is a beautiful cone I cleaned the base of. There are no additional denticle structures at the base and it doesn't look fractured at the base either. It is just under 1mm in length. I could also be totally wrong and its a fish tooth .The second is also a Stark shale element, but I'm not going to guess what elem

    Unknown "toothed" microfossil

    So...while splitting my thousandths shale and looking under the scope, I came across this organism, which appears to have interdigitating teeth?. At least most look interdigitating as opposed? Or , I just dunno. There is also a surrounding imprint on both sides. It was found in Stark shale Kansas City Missouri and is nearly 2mm long. I have two views, and can get the other split side, but this is the best images so far.....ANY thoughts, would be appreciated!....In my very limited (one month :)) experience looking at conodonts, this doesn't appear to be one, (S elements?) but, I've been wrong s

    My Kansas City conodonts

    The past month or so I have had a chance to examine some shale from the Stark Shale, Dennis Formation, Kansas City Group. I have found many conodonts and I’ve enjoyed the challenge of taking pictures of them while they are still embedded in the shale. I think I have over 100 specimens now. Below I have posted some of my results. I have tried to identify the element position (P, S, or M) according to Purnell, Donoghue and Aldridge’s “Orientation and Anatomical Notation in Conoodonts,” Journal of Paleontology, 74(1), 2000, pp. 113-122, although I have not distinguished among the various S

    Filming Conodonts

    Hi! I recently acquired a bunch of microfossil samples for kids to play but did not expect them to be so small. We tried some microscopy but ended up applying a little trick that actually to helped to film them "in action", which was kind of cool. I do not know if this technique is a common knowledge or not but I decided to share. Perhaps, it will be of use to somebody. Here you go: Any suggestions for improvements? Thanks!

    scolecodont or conodont?

    Hi again! Over the weekend, I posted pictures of small fossils in a rock I found at Mimico Creek in Toronto, Ontario (Georgian Bay Formation, Upper Ordovician). I've created this new post just for the shiny black specimens that I found in the rock because a consensus wasn't reached regarding their identity. Each of the two specimens pictured below are 5mm long. My question is: are these items scolecodonts or conodonts? I was leaning towards scolecodonts but I wanted to see what others have to say... Thanks once again! Monica
  22. Can someone help me identify the item that is with these two conodonts? My guess is a fish scale. This is from the Stark Shale, Dennis Formation, Kansas City Group. The conodonts are 2mm or so and the specimen is 7mm. I am intrigued by the surface of the "shell" which is a bit crab-like (I'm not saying I think it is crab, but that the item's shell has that kind of texture). I've included pictures of both the item and its external mold on the other half of the split shale. Let me know what you think. Russ
  23. I think this one is a conodont (see tags for formation, location). Scale in mm. No conodonts were reported by Ehlers (1973) thorough study on these formations, so I am guessing if this is a conodont, it's a somewhat rare find.
  24. Pseudogygites

    Belemnites? Conodont?

    Greetings again TTF! The Billings formation is just filled with stuff that I can't identify! This time, I have found some glossy, cylinder-shaped things in the Billings Shale. I know that conodont elements are known from some parts Ontario and Quebec, but I think that it might be a belemnite as well. They seen to be associated with crinoid stems, brachiopods, and one Pseudogygites Lantimarginatus pygidium. They are each roughly one centimetre long. They are in the centre of the first picture and the second picture.
  25. As I have continued to examine the conodonts I'm finding in Stark Shale Member material (Kansas City Group, Pennsylvanian), I've found what appears to be a group of conodont fragments. What does this look like to you all? Russ
