  3. Spent a few hours earlier today fossil hunting Ordovician strata in the Jefferson National Forest near New Castle, Virginia in Craig County for the first time. Was well rewarded with several plates covered in brachiopod compression fossils. Also found what I think is some sort of burrow. Also found an odd fossil that I can’t identify, I will post it in the ID forum later with a higher resolution microscope pic and a scale, but for now I will post what I have..

    Orthoconic nautiloid?

    Hello. Any comments on this find (3 photos below) at Mimico Creek in Toronto (species, anatomy, etc.) would be appreciated!

    What kind of crystallized fossil?

    If crinoid stem, why encased? (Found in Mimico Creek, Toronto)
  6. I recently found this peculiar fossil, I know that it is from the Ordovician period, because of the formation where it was found. But I cannot figure out if it is a piece of a trilobite or a cephalopod, or something else? It look like it have to round half that are joining in the middle.

    Small decalcified fossil

    Hi, this is a decalcified specimen (upper Ordovician - NE Italy). In order to understand the fossilization process of these specimens I've linked an image (Fig.1) of the internal mould of a Caryocrinitida (Rhombifera) with basal plates and stem facet preserved (from the same slab). So we're talking about the mould of the calcified parts of a living thing. Then I've linked some images of the specimen to identify: 2a-2b the whole specimen. 2c-2d I've carefully opened the slab. The "internal" part (?) 2e-2e_edit the "external" part (?) I'm wondering about a
  8. Found this yesterday in Mason County, Kentucky in the general vicinity of Maysville where Ordovician limestone (Bellevue Formation?) is exposed in the roadcuts. Not an expert but hunted enough to immediately appreciate the rarity of the find. After some preliminary research and a tentative identification (Carneyella ulrichi) I seek an expert review and confirmation/correction. These animals seem to be sufficiently rare that a firm ID shouldn't be left up to an avowed un-expert ... who knows little about the differentiating characteristics of edrioasteroids (or even echinoderms) to do more t
  9. Last month I was able to make a brief trip to hunt the Ordovician rocks of the Upper Mississippi Valley. The stratigraphy up here was very confusing to me at first since a lot of the units are very similar looking. To that end, I am endeavoring to include more site pictures in my trip reports of this area, in the hope that it will assist others when collecting this area. My first stop was in SE Wisconsin. Unfortunately the right of way was much narrower in person than on Google Earth so I did not feel comfortable collecting here. But it was a great site to observe the three lowest

    A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :

    A Physicist's Collection

    While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part

    Local Ordovician Trip

    It has been 7 years now since I became hooked on the "fossil thing". My hunts seem to creep a little further from home with each passing year. Greener pasture syndrome. So a few days ago, I purposely started my adventure close to home. Here are a few finds from the Ordovician. @ClearLake Let me start with a few unknowns: This last one could just be a squished brachiopod, but seems to be a coiled organism. IDed as Trilobite eye, probably Isotelus The pygidium pictured came from a new spot I tried, expecting to find
  14. Hi, I'm a newbie to this forum and would really appreciate some help identifying a fossil that my son found last week in mid-wales, Upper Gilwern Hill Quarry, Powys. It was found in the same strata of slate with trilobites that the quarry is famous for. multiple photos attached. Many thanks in advance for anyone who can help identify it.
  15. Today I stopped to stretch my back and did about 10 minutes of collecting near Whites Creek, Tennessee- I believe that this might be Richmond Group Ordovician. I would be looking for a little help on some IDs, I believe @Peat Burns, @Herb And @Tidgy's Dad might be able to help out. Here are some of my finds- Brachiopods- Gastropods- Bryozoan- I believe that the smaller pieces are Constellatia Florida. Hash Plates-

    Bryozoan, ordovician

    Hello guys! I did some cleaning in the backyard in Deux Montagnes, 10 km North of Montreal. In a piece of rock I found some fossils of mostly bryozoan. Could you suggest what time these could be? I guess it is near Ordovician. It is sedimentary, 2 layers of such sediments, between them there is quartz or silicium rich sedimentary layer . The layer on the top is fragile, layers bellow are hard. 1, 2. 3, 4. 5. 6. 7. 8.

    Maquoketa Fossils

    Early in the summer, an attempt was made to hunt a different Ordovician formation than I normally collect in. It provided me with a learning experience and some new and neat fossils. Having enjoyed my finds so much, a return trip was made 2 weeks ago. Not to the same site but to a more extensive exposure of the Elgin Formation of the Maquoketa close by. The location is in NE Iowa in some beautiful farm country. Even if I found no fossils the view from here made the trip worthwhile. Now for the finds. I am a novice at identifying fossils from this formation and am open to a

    A few crinoids

    I preface this by saying I'm not a crinoid collector, nor someone who has the foggiest idea of how to prep them effectively. If I encounter one that looks relatively complete, I'll bring it home. I focus prep on trilobites mostly, and there is a thread where I park those. It's been a busy week at the bench, and I thought I'd close it out with one finished piece, and one that is halfway done. First up is the finished piece. I didn't take a before photo for some reason, but these appear as faint traces in this material. This one is an Ectenocrinus. It already had some da

  20. While heading to visit family in southern Indiana, I decided to leave a day early to do a bit of collecting in the Cincinnatian. The first stop was, as usual, St. Leon, to look for the famous Flexicalymene rollers. In the past, I've usually found 2-4 per visit, but was quite lucky this time, walking away with 10 rollers and my first prone. Here are a couple in situ shots. After a couple hours at St. Leon, I headed towards my hotel. As it turned out, it was just down the road from Trammel Fossil Park. I had not been here before. It ex
  21. Here are two bugs not in great shape from the Elgin Member of the Maquoketa Formation (Upper Ordovician) of Minnesota. I am leaning towards Flexicalymene sp. for the first and guessing Isotelus or Anataphrus for the second. Any thoughts are appreciated.
  22. Last week, some fossils were collected from the Elgin member of the Maquoketa/Ordovician of NE Iowa. A few of my unidentifiable ones are posted here today for you to look at. 1. The first one was a cephalopod mold that upon closer look at home had these 2 "things" stuck to it. I have not come across these before. 2. Next is a partial trilobite that I initially thought was Anatophorus. But after some cleaning , I am uncertain how to label it. It appears to be crushed.
  23. I found this fossil in the Georgian bay formation in the GTA in southern Ontario. I have no idea what the area highlighted in blue is (first picture). It looks like a slug or some type of annelid. My only guess is some type of Machaeridian, but I doubt it's that as well. Any ideas? It measures around 9 cm tip to tip, Thanks
  24. I've been super excited for this book to be released since I heard about it last year. The diversity in the Platteville is astounding, but there are not a huge number of publications on its fauna, and most without pretty pictures. I just ordered my copy. Dennis Kolata is the Platteville expert, so I have no doubt this will be a phenomenal book. https://isgs.illinois.edu/achievements/august/fossils-upper-ordovician-platteville-formation-upper-midwest-usa-overview
