  1. Tiny Unknown Devonian

    @Peat Burns, This one is for you. I am staking my reputation (which doesn't mean a lot) on you to be able to ID this Paulding, Ohio unknown. Your info on species of Paulding mounds has been very helpful to me so far. Collected in early January.
  2. Silica Shale

    Date: Jan. 5, 2019 Location: Paulding, OH Formation: Silica Shale Time Period: Middle Devonian (Givetian) Species collected: *Bethanyphyllum or Heliophyllum *Cystiphylloides americanum *Aulopora microbuccinata *Stropheodonta demissa *Stropheodonta sp. *Megastrophia concava *Pseudoatrypa devoniana *Athyris sp. *Orthospirifer cooper *Mucrospirifer sp. *Limoptera macroptera *Eldredgeops rana @Nimravis
  3. Devonian Mystery Hypostome (to me)

    I found these items while working through the calcareous shale my wife and I collected from Paulding Ohio this summer. This material is primarily from the Devonian aged Silica Shale. I found one and didn't think too much about it, a fragment of fish/trilobite/shell or something else perhaps. Then I found a second which looked similar and so I did some prep and was able to expose more of each piece. These are small (those are mm's on the scale) with the biggest one being about 10mm by 12mm and the smaller one a little over half that size. They don't look like anything I'm familiar with nor could I find any matches in numerous books or online sites. I know the pictures are not ideal and they are embedded in the rock, so nothing from the side or underneath (first two pictures are the same one). They are very dark in color like much of the trilobite material. Oh snarge, it just dawned on me. Are these hypostomes? I don't think I have ever seen one before. Maybe I answered my own question, but I typed all this already so I'm going to post it just to make sure. Thanks, any ideas would be appreciated. Now I see a thread from 2011, so yes, these are hypostomes, but I'm uncertain on which species it is from. Looking for examples from Eldredgeops and Pseudodechenella since those seem to be the genera present in the Silica.
  4. Brachiopod KOH prep

    Here's a nice, large brachiopod I found at Paulding, OH, yesterday. The Silica Shale is rich in organics and lends itself well to dissolution with KOH, a strong base. Here is the "before" pic after cleaning the fossil with a brass brush. The remaining matrix is rock, not "dirt" and would take quite a bit of time to remove with a pin vice and air abrasion.
  5. Pseudodechenella lucasensis

    Here is a prep series of a tiny Pseudodechenella lucasensis from the Mid-Devonian Silica Shale that I found in Paulding, Ohio, yesterday. Not complete, but not a common find, so I am very happy with what I got. I'm probably going to restore this by sculpting the genal spines, etc. 1. Farm Fresh 2. Roughly exposed with pin vice. 3. More cleaning with pin vice. 4. Final product after air abrasion with dolomite. 5. This is a tiny one...
  6. Paulding, OH (July 8, 2018)

    Whelp, patience pays off. I got a new species for my Paulding list today: Basidechenella lucasensis Since this photo was taken, I've exposed all of the fossil. Most of it is there except the left librigena and left side of pygidium. I'm very happy with it, nonetheless. I'll post pics when the prep is complete. I won't post all of today's finds, but here are a couple other highlights (for me at least ): Not sure yet if this is Stropheodonta titan or Megastrophia concava, but this is a nice monster that will prep out nicely. This is a really nice horn coral, because it is large and complete from the tip of the base to the tip of the calyx. It will prep out beautifully.
  7. I spent the Holiday weekend in Port Clinton, Ohio visiting my relatives. On my drive to there, I made a slight detour so that I could visit the fossil site north of Paulding, Ohio. I must commend La Farge Quarry for their creation and upkeep of the park!!!!! They must, unlike most quarries, realize the treasures that lurk within their rock. The park consists of about 10 rows, 100 feet long of fossiliferous rock they provide for the public's enjoyment. Some of the piles are weathered and some are fresh. Certain species are better found in the weathered rock, others in the fresh. Look at both!! Here is a sampling of what can be found in a few hours of collecting: Brachiopods abound from small to large.
  8. Devonian Brachiopod

    Here is a large brachiopod I found recently at Paulding, OH. Distinguishing Megastrophia from Stropheodonta titan can be difficult, but I think this one is S. titan due to its low profile. The side shown here is largely exposed, but the other side was covered in matrix. Unfortunately, this field photo is the only "before" photo I took. I decided to leave this one on a pedestal of matrix. The matrix was really sticky. The bulk would pop off with the scribe, but a thin layer clinged to the shell. So rather than scratch up the shell with a pin vice or take hours blasting it, I prepped this one chemically with KOH flakes. About 80% of the "prep" was done chemically. The Silica Shale is rich in organics, and the KOH turns the shale into mud. I made several applications on the thick areas of matrix. Final procedure included reversal of the base by a quick dip in 5% glacial acetic acid and then a good soak in water. Here's the result.
  9. Paulding, Ohio (April 2018)

    Another great hunt in Paulding, OH. Weather was windy, rainy, and cold, but neither the fossils nor the avid fossil hunter seemed to mind. Here are some of the finds. I have also begun a working species list for the site in the Ohio fossil sites subforum linked here: Paulding Species List

  11. UPDATE: This could be Murchisonia sp. which has been recorded from the underlying Dundee Limestone and deposited in the Ohio State University Museum of Biological Diversity. Hello, I found a rare conispiral gastropod steinkern in the middle Devonian (Givetian) Silica Shale of Paulding, Ohio, last week. It's the first strongly conispiral gastropod I've ever found in the Middle Devonian (let-alone the Silica Shale). I looked through the FUMMP online database as well as the "Strata and Megafossils of the Middle Devonian Silica Formation" published by FUMMP and couldn't find any taxa that looked like this. It has the general shape of Paleozygopleura known from the Hamilton Group of New York. Is anyone aware of a snail with this general morphology that has been reported from the Silica Shale? Scale in mm.
  12. Are these crinoid arms?

    Hi. I've spent the winter reviewing my finds from 2017. Here are two images. Initially I thought the radiating arms were those of a brachiopod, but I'm now having my doubts. Could they be crinoid arms? (The specimen in the top image is on the upper left corner.) I failed to include a measurement scale, but the top specimen would be covered by a penny, and the bottom by a nickel. They're tiny. Thoughts? (Paulding, Ohio; Middle Devonian; Silica Shale)
  13. Trilobit, Silica Shale

    This might be a job for @piranha This trilobit looks a little different to me than the typical Eldredgeops. Maybe Dechenella lucasensis? I didn't realize how poor the photo quality was until I cropped it. I can take more photos under the scope if necessary. Silica Shale, middle Devonian (Givetian), Paulding, Ohio. Scale in cm/mm. This one seemed different as well.
  14. Nautiloid camera?

    Is this what I think it is? A camera steinkern of an orthoconic nautiloid? This is from the middle-Devonian Silica Shale of Paulding, Ohio (although because it is quarry spoil, there is a possibility it could be the underlying Dundee Limestone). I don't think I've ever found an orthocone in the Silica Shale, let alone one this large. I hope this is not something that has been intentionally or unintentionally salted in from another site... That really burns me up.
  15. Silica Shale

    Hello, Found these interesting "fronds" in the Silica Shale on Sunday. My best guess at the moment is the bryozoan Reptaria stolonifera. Looking for confirmation or other suggestions. Hope these photos are sufficient. It was a tough one to photograph.
  16. Anthroacantha carpenteri

    This silvery gray crown of a fossil Crinoid is quite impressive for its vascular arrangement of arms and protruding aboral cup. However, it is the nature of its preservation that makes this piece very special. The fossil is pyritized as the metallic mineral Pyrite replaced the organic matter during mineralization.
  17. Well I'm on my way to Utah for a new career opportunity and looked up the LaFarge quarry in Paulding Co. last night. This quarry is supplied with dump trucks worth of shale from the LaFarge quarry that pulls directly from the Silica Shale formation Devonian era. The location is in the middle of nowhere and my wife gave me one hour to look around. Soon I had my five month old daughter, Clara, strapped to my chest in a baby carrier and I was quickly scrounging around looking for fossils. I can tell you that I was not disappointed though I did not locate a complete Eldredgeops roller I did walk away with some very large brachiopods and the largest horned coral I've ever collected. To anyone seeking to collect fossils in the mid-west or Ohio, this location is a must. All this came out in under an hour of searching and some of these pieces could look good after some light preparation. See descriptions below: This place is in the middle-of-nowhere Ohio. The parking lot was gravel with a portable outhouse. The nearest gas station was about twenty minutes away. I was talking to @Kane about conglomerates of fossil bits and he noted similar compositions at both Penn Dixie and Arkona. I know there's a scientific term for what this occurrence is but I can't seem to recall the word at this time. Regardless I find these settings interesting as they don't seem to preserve anything exceptional, certainly not a complete trilobite but it's neat to see so much life in one piece of sedimentary rock. This particular rock is full of pieces of bryozoans, crinoids, trilobites, and brachiopods. Someday I'll invest in an expensive microscope to examine these different pieces. I usually don't keep horned coral but I couldn't resist keeping this one. The interior calcium based structures have crystalized and it is by far the largest horned coral I've ever picked up or seen in person though they can get bigger. There were Eldredgeop cephalons and pygidiums everywhere. Similar to Penn Dixie this is a really good sign that potential complete pieces, particularly rollers are present. I believe the terms of the site are that tools such as hammers and chisels are not allowed as the shale pieces are small and brittle enough to break in hand. I believe that a few years ago access to the official LaFarge quarry was granted but that was recently retracted and a number of amateur paleontologists wrote letters to the company requesting something be done to continue to provide access to the site. I'm really glad LaFarge goes out of their way to dump some scraps for people to pick through. Site admission is free and you can keep whatever you find. Large piece of an Eldredgeops segment sticking out of the matrix surrounded by brachiopod pieces. What a scene this must have been during the Devonian. The camera doesn't do this pyritized piece of shale justice. Hopefully I'll be able to take some micro pictures later of the square crystals. One of the larger Eldredgeops pygidiums I've ever seen and I read some sources last night that the trilobites in the Silica Shale can be very large. Almost every trilobite piece I came across at the site was very large. This pygidium is almost an inch wide. There were many spiriferid strewn throughout the site. Most had both halves and exhibited excellent color. Large cephalon. More pyrite. The large horn coral. More pyrite amidst a conglomerate of fossil pieces. A complete brachiopod out of the matrix. Front view of the brachiopod. I'll have to ID this one after some cleanup and polish. I really like the color on the corals and fossils at the site. This is a light tan. Another large complete brachiopod. A long spiriferid with what appears to be both halves. This one should prep out nicely. The desert of farms and trees of western Ohio. Corn, trees, and farms all around. Another good sized Eldredgeops cephalon. Yet another horn. Large Eldredgeops cephalon poking out. Not complete but gives me hope that there might be some complete specimens at the site.
  18. Ohio sites?

    I was debating posting this under the Ohio fossil discussion but am passing through Ohio on my way out to Utah and wanted to know if anyone knows of any good spots to go to. I hear that there's a fossil park in Paulding with the famous Silica Shale trilobite layers. I have all the tools in the car and my wife said I could go out for about two hours tomorrow though it might be one with a cat and newborn.
  19. Crinoid calyx?

    Could this have been a calyx? Or just some slate shale? It pretty much crumbled when I tried to clean it. 1 inch round.
  20. Silica Shale Placoderm

    Im just curious, not planning to buy or sell one, but I was wondering if anyone has actually seen a placoderm fossil from the Ohio silica shale for sale anywhere? Or even just a reasonably complete carapace in a private collection? In particular Macropetalichthys rapheidolabis which appears to be a less rare one.
