  1. I collected this bivalve cast a couple years ago in the Silica Shale (Middle Devonian) of Michigan. I'm not super positive on an ID and was hoping someone here might have some thoughts. @Peat Burns @Misha @Tidgy's Dad? Thanks for any help.

    Pyritized Arthroacantha?

    Hello, I'm considering this crinoid from the Silica Shale of Ohio, Arthroacantha carpenteri. From what I understand, the unique preservation of this site for these crinoids is a pyritization/pyrite replacement. This specimen seems to have sparkling up close, but it is not apparent from a distance. Does this one indeed seem pyritized? I'd like it if it's a nice, representative example. Thanks.
  3. Hello everyone, I have been wondering about this for a bit but only now that I atually have one of these in my collections have I decided to ask this, All of the P. bownockeri I have seen have been pyritized and I wanted to ask why this is, I do not know of any other brachiopods like this because while there are some I have seen preserved in pyrite they are from areas where the rest of the fossils are also pyritized, from what I have seen its mostly just this species that is commonly found fully pyritized from this formation. The only thing I can think of is maybe they are found
  4. I found this specimen in the Silica Shale (Middle Devonian) of Ohio this past weekend. It measures approximately 2cm at the widest point. I have not come across anything like it before. I'm getting a fish vibe but I'm not certain. Any thoughts? Front Back

    A lucky Devonian find

    This past weekend I was able to hunt in the Middle Devonian Silica Shale in Ohio for a couple of hours. I found a lot of great things, but I think this took the cake for me. It was my first good find of the day, and the only specimen I've found in 5+ trips to this site. I don't have my Silica Shale book with me right now, but I believe it to be Hyperoblastus reimanni. In situ Cleaned up
  6. I found a variety of brachiopods in the Devonian Silica Shale Formation near Sylvania, Ohio, in mid-August. A few are a bit pyritized.

    Paulding Gastropod

    I found this very compressed gastropod over the summer at the dump piles in Paulding, OH (Silica Shale, Devonian). I don't recognize it. Any thoughts? @Peat Burns @minnbuckeye
  8. Hey everyone! Happy to finally be making another entry. Over the last couple of weeks I've been reading Richard Fortey's "Trilobite" and thus itching to get back into the field and see some for myself. Driving from New York to Chicago I decided to make a pit stop at Ohio's Paulding Community Fossil Garden and try my luck at finding some eldredgeops fossils. Here's what the garden looks like when you arrive: You're basically wading through fossils step after step. Here's the best of what I found, excluding some nice surface-collected brachiopods I've b
  9. I recently purchased some Mid Devonian silica shale pieces with trilo-bits from @connorp. And by recently I mean last month... last year..(January is always confusing that way). Just several small pieces with partial molts I'm using for practice prepping. So after picking at a few all year... one of them has gone from a practice piece to an almost show piece. 1st pic is the original sales pic with the piece circled. In it you can see part of the trilo-bit, but not really anything else. I got a nose w/ a partial eye (base only), bryozoa scattered about here & there, some tiny crinoid pieces

    Paulding Ohio Trip

    Lafarge Holcim Cement Plant in Paulding Ohio continues to provide a near perfect solution between safety issues within a quarry and the desires of fossil hunters to check out a quarry's material. They graciously and continually provide fossil laden Silica Shale just outside of the quarry for us to play in ANYTIME we want!! Such was the case as I traveled back to Ohio for an "after Thanksgiving" Thanksgiving at my sister's home in Lima. I was able to spend a little over an hour picking up some representative fossils. Brachiopods abound as do trilobite pieces. I did manage a large sized, almost
  11. On my way to Ohio to visit relatives, I was close enough to Paulding Ohio to take an hour or two to check out the Silica Shale piles so graciously put out by the La Farge Quarry. As always, it didn't disappoint! I do have a few fossils that I am a little unsure of. @Peat Burns Hopefully someone can help out. Mike First off, this one is HARD TO SEE. I photographed it 3 times and can't get it's subtle details to come through. I am 90% sure of bivalve. It comes to a point and the striations are along the growth lines, not the ribs. Second up is what I thin
  12. For the better part of a year I have been meaning to meet up with Tony @Peat Burns and do some fossil collecting. I have never met him before but we have PM’d on numerous occasions and he has helped me with ID help on a few items. Here is Tony- Well today worked out well for a couple of reasons, first we set the clocks back one hour which made leaving a 5 am for the 4 hour drive not to bad. Second, I crossed into the Eastern time zone so when I drove back, I felt 1 hour younger. Third reason was that I had a trunk full of various fossils that I wanted to gi
  13. 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 a

    Paulding Ohio Find

    Found this at Paulding Ohio Fossil Park. This is the only one in 5-6 visits to this location. Is this a rare find?

    Two More Paulding Ohio Finds

    I found these at the Paulding Fossil Park. I originally dismissed one as a horn coral as they are plentiful there. On closer examination it doesn't fit the typical growth pattern of a horn coral, no cone shape, no growth rings around the circumference. It is 1-3/4" in length. Could it possibly be a tooth? The spike shaped item is 2" long.

    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.

    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.

    Paulding OH unknown

    I found this thing when I was sorting through the haul from a recent trip to Paulding (Silica Shale, Devonian). I have no idea what it is. Only thing I thought of is some kind of fish bit, really just because it doesn't look like anything else from Paulding that I'm familiar with. Any ideas?

    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.

    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

    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...
  23. 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.
  24. 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!!
  25. 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
