  1. Hello to all. 3 samples from my collection. Place of find - Ukraine, Khmelnytsky region; age - Silurian, Ludlow Series (425-427 Ma). All samples have retained positive and negative. 1. Slab with several sea-scorpions Eurypterus Tetragonophtalmus. I think a good preparation will open as many as 2 or 3 sea-scorpions.
  2. I'm currently working on a simulation of extinct biomes, i'm slowly learning how to make everything as realistic as possible for realtime 3d simulation. I would like to start with plants recreated from some Silurian, lower devonian and upper devonian, and slowly working to recreating the biomes in the areas where they lived and later i'l like to add animals aswell. All my research is made with google i'm not a professional in archeology or 3d art, some of the models are very simple and unpolished for now and will be updated. The project is in the early stages

    Straight Shelled Nautiloid? Buffalo, NY

    Hello all! Sorry for the lack of measurements in these photos, I’ll be sure to upload some soon once I get the chance to. This is my favorite find so far in my early adventure of fossil hunting in western New York. I am more well versed in vertebrate paleontology in the central plains, so I apologize for my lack of knowledge on these earlier guys. I found this one in a rock exposure along a parking lot adjacent to Bennet Quarry- this is where hundreds of eurypterid specimens have been collected. I assume that the rock this is from is similarly aged, and a part of the Bertie formation. It is a
  4. What better way to celebrate the end of the year than with a little fossil hunting? And the hunt ended with some spectacular stromatolites; read on! ----- When I got an itch to hit the field last month, I reached out to a quarry in Perrysburg, Ohio to collect fossil and mineralogical samples for donation to academic institutions. The quarry was kind enough to grant me permission to collect on their property for several hours in late December, so when the time came, I suited up and headed out with a trusty assistant. The quarry exposed outcrops of the Lockport and G

    Truncatiramus Eurypterid WV?

    I was wondering whether this belongs to a Eurypterid. The only recorded genus of Eurypterids at the locality is Truncatiramus. Formation: Bloomsburg-Williamsport Formation. Age: Silurian. Other recorded fossils: Tentaculites sp., Klodenella sp., and Stromatapora sp. Second photo:

    Unknown pygidium

    At first I thought this was the Trochurus pygidium. I've been looking for for a few years now, but since it appears to have 6 spines instead of 4, not so sure. Maybe Ceratocephala? Sugar Run. @piranha

    Are these crinoids?

    These three fossils in the upper left of the picture were found in central Pennsylvania. I am relatively new to the world of fossils so I'm hoping someone can help identify what I have found. Are these crinoids? Thanks in advance!

  9. Hey Folks, I specialize in the Middle Silurian Waldron Shale formation. However, I have many other North American Paleozoic invertebrates from many classic sites. I would be happy to exchange this material for any good Waldron Shale fossils, prepared or unprepared. I'm located in Ohio. Drop me a line and let me know what you have and what taxa you may be interested in. Look forward to hearing from you. Note: If you would like to exchange Waldron material you have for Waldron fossils I have...we can do that. For instance, if you have unprepared Waldron fossils I c
  10. Hi Everyone, In the latter half of last month I took a two week trip to Kentucky and Tennessee. My sister, her husband, two of her adult children, and my parents all live in the Elizabethtown/Louisville area and I was able to spend some quality time with them. Fossil collecting was also part of my agenda. Herb, my primary fossil collecting partner in Kentucky and I had a three day trip down to Tennessee planned. Before I went on that expedition, I was out with my brother-in-law driving around central Kentucky. He dropped me off for 20 minutes at the Upper Mississippian site at Wax where

    Silurian/Devonian horn coral?

    A friend gave me this ... horn coral? collected somewhere in the vicinity of Springville, Iowa, just northeast of Cedar Rapids. Macrostrat has that entire area underlain by Silurian to Devonian marine carbonate rock. Would be nice to confirm it's a horn coral, and perhaps get a more specific identification. Ruler marks are cm. It will be difficult for me to get a deeper macro with the camera I have, unfortunately. (And, if seeing these didn't have you mentally hearing "budda budDa BUDDa budda" played by a heavy brass sect
  12. Hi everyone, went on a nice little expedition into West VA over thanksgiving break. tried my hand on checking out the rose hill formation in Waiteville. lovely time out with some beautiful scenery and farms. The sandstone was sparse fossil wise, but I did find three pieces with some interesting stuff to ponder. here are each of the three rocks, labeled Specimens A-C Specimen A looks like it has some simple fossil impression. on first inspection there's some nice Ostracods and a couple brachiopod impressions in the middle. but on closer inspection on the edges I noticed t
  13. Can anyone tell me what this species of coral is? It's from the Thornloe Formation in Northern Ontario, and is of early Silurian age.

    Brachiopod?

    Hi folks, would love help with a fossil ID. Specimens were found in one piece of loose rock, on the banks of the Otter Tail River, Fergus Falls, MN. I'm guessing it's a brachiopod of sorts. Not sure how to determine the period it came from as this is not from an outcrop here, and we're situated on glacial till and granite. It looks somewhat like pentamerus oblongus? Anyways, any help appreciated!

    Silurian Trilobite Help

    I recently collected in the Rose Hill Formation in West Virginia. I found a lot of small trilobite pieces and a couple brachiopod and pelecypod fossils. I am having some trouble figuring out what these two fossils are. Any help would be greatly appreciated. Please let me know if you need any additional photos. #1- the piece at the bottom of the photo measures about 0.5 cm tall and 1 cm wide. I found a similar looking fossil below. No clue what it could be... #2- the pygidium measures about 1 cm tall and 1.3 cm wide.

    Geological Time Question

    The weather is turning here in Ontario Canada, leaves are raked, stuff is stored safely away, waiting for the lake effect snow. Went for a walk along the lake and well couldn’t resist this rock. Here is my question: In geological time, what do you all think is the top and what is the bottom? Is the limestone newer or older than the layered what I believe is silicate. Every rock tells me a story, I see the impact of multi cell animals, and what I believe is the heavy tidal action of the Silurian sea because of heavy gravity interaction of earth and moon, cephalopods, bivalves, …
  19. This encrinurid occurs in the Temiskaming outlier of northern Ontario amidst a fauna that is similar to that of Anticosti Island (1,250 km away). The layers in which these are found represent a near-shore environment, containing an assortment of crinoids, coral, early plant material, brachiopods, and a variety of gastropods. The specimen plate shown here was painstakingly prepared by M. Thornley of Ontario during the late summer of 2021. The specimen plate contains up to 12 or more individuals in various states of completeness, and is housed in the private collection
  20. Hi, all. I collected this specimen in the New Point Stone quarry, near Napoleon, Ind. It's Silurian, and was found in the Massie Shale. But I can't seem to find any information about it, specifically, the genus or species. The experts to whom I reached out were stumped. Any ideas, ladies and gentlemen?
  21. The brachiopod fauna of the Leighton Formation is so small that I don't often find one that needs some help with identification. This individual does. The closest brachiopod that has the same characteristics is Eoplectodonta (=Plectambonites) transversalis, but it only occurs in the Dennys Formation. The Dennys Fm has quite a different fauna from the Leighton, but it is the closest thing I could find. My other option was some sort of small spiriferid. I will have to defer to @Tidgy's Dad for this one. Below are two pictures of it, first of the cast, and second of the external mold
  22. Well, it has been a while since a post on the Silurian Leighton Fm. Had to make a trip due to family matters, and once I got back had a lot of work to do. I finally got into a position to start splitting and prepping more shale, and found this new little guy. I am torn between an operculum of a gastropod, and an inarticulate brachiopod. My main argument for an operculum is because of the shape - the only inarticulate brachiopods in this formation are Orbiculoidea and Pholidops. Unfortunately, I cannot find any reliable papers on the brachiopod Pholidops, it looks very similar but
  23. After a summer-long hiatus, I went out to look for some trilobites the other day. I wasn't finding much but the weather was just right: overcast, threatening rain clouds, periodic drizzle, a nice breeze, etc.. so I lost track of time. After a few hours and not finding much beyond the usual suspects,, I was getting ready to leave. I split one more and this block contained three Cerauromeros hydei cephali and upon taking a closer look seemed to show indications of being complete. Gravicalymenes, brachiopod 1 2 3.

  25. I found a new place to fossil hunt and it has many more fossils then the normal places I go. Lots and lots of coral, brachiopods, cephalopods, and crystallization. It honestly looks like a coral reef of some kind. I live in middle Tennessee and it's mostly Mississippian and ordovician in my area but there are some areas of Silurian-Devonian. I found this fossil first and thought it was some sort of larger cephalopod, but there were some strange things about it and I started to change my mind. It is a torpedo shaped fossil with crystallization. I will start with the pattern pictures first
