Ik know this isn't a fossil but i thought people probably have experience with pyrite here so i though i'd give it a shot. I've had this piece for a year or so and as you can see it's corroding pretty bad on top, is there a way of stopping the corrosion once it has begun? If not i'll try to cut off the bottom half so that that might survive.

Simple question. Would the application of Butvar B-76 prevent pyrite disease??????? I hope so. I just applied some to the pyrite I collected from the Pella beds, Pennsylvanian of Iowa.

Dominican Amber (La Toca Fm., 20.43-13.65 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Dominican amber from the La Cumbre Mine, from the Cordillera Septentrional. Most pieces range from 5-10g in weight, with at least one containing a large two-phase inclusion (enhydro). Material from this mine frequently presents exterior crusts/aggregates of pyrite (iron sulfide); these were likely formed in a reducing, marine/lacustrine environment, where marine sediments, organic detritus, volcanic material (i.e., ash), and sulfate-reducing bacteria helped to provide the sulfides and iron needed.© Kaegen Lau

Hi guys Went over to Sheppey yesterday to see what I could find... I'm a total novice, so I tend to pick up anything with an interesting shape and/or texture. Found some pyritised wood/twigs, a bit of crab in a phosphatic nodule, a little gastropod and some very round seed pods. The following pics are of the ones I had trouble figuring out due to their shapes resembling other things. Any clues would be great! Thanks ONE I'd like to think it's some kind of pointy reptile scute, but from my browse online it's possibly a pyritised seed husk? 3rd pic shows the depth of the piece and a VERY smooth and shiny blob inside TWO & THREE LEFT: Again, probably a seed pod/husk. Has a pitted texture similar to a piece of crab shell, but a lot less uniform. Kinda reminds me of a Tapir toe RIGHT: Possibly a shrimp? lobster? Maybe some clustered belemnite parts? Looks like a very full hot dog bun haha. Had to wet it to bring out the details. FOUR I thought some encased bone or wood? Online research leads me to believe it could be a lobster burrow? The back is solid light brown rock with no inner black part showing through. FIVE Had to dunk this one in some water to get the details and colour to come out. 3rd pic looks a lot darker and shinier for some reason, but it's not coal. Fossilised wood- with possible bug borings? (based on the dotty parts in the 2nd pic) Hopefully there's something vaguely interesting here haha Thanks for looking

Anyone any ideas on this? I picked this up because the multiple ridges and shape was interesting. Now I’m home I’m more and more intrigued by it. Was laying at the cliff base.

Hi everyone, As a beginner i have picked up some pyrite nuggets which hopefully have fossils underneath (hopefully an ammonite). I am wondering which is the best way to uncover what lay beneath (if anything). Lots of mixed methods on the web so can anyone advise which is the best way to start please. Thank you

I was in Sylvania OH this weekend and among many other pieces, I found these. I finished prepping them as soon as I could. The first is a pyrite paraspirifer bownockeri.....it is perfect, not a blemish or chip. This one is a paraspirifer (I think) but different. About 2 inches across. Has a few flaws. Then there is another pyrite bownockeri, same size as the first one, nearly perfect but for a chipped "wing" and a hole. But the hole exposes that it is also a geode....containing calcite I believe. I've never seen or heard of a geodized pyrite fossil. Does anyone have one?

Hi all, I recently acquired the below fossil, a pair of articulated jaws, purportedly from Pachystropheus rhaeticus, still with teeth, found at Garden Cliff/Westbury-on-Severn. Whether I wasn't paying proper attention when I bought it or just hoping there wouldn't be any pyrite on the piece, when I received the specimen it turned out that there are quite numerous pyrite-crystals growing to the side of the fossil. As it's quite an unusual piece that I'd rather like to keep, I'm now looking for people with experience with pyrite from the Garden Cliff location. In essence, I'd like to ask how stable the pyrite from this location typically is: whether it decays into a black oxidation product or starts blooming with time. How concerned should I be about the stability of this piece? The pyrite itself looks relatively clean right now, so I'm thinking the rock on which the fossil sits hadn't been exposed for too long. But any advice would be welcome. @Welsh Wizard @Pterygotus @DanJeavs

How are these pyrite sphere made? These were found in Georgetown, Texas 20210101_021548.mp4

Hey everyone, So this summer, like most summers, my family went to my grandpa's holiday house in southern France. Seeing that we had many days with nothing planned, I managed to convince them to go fossil hunting one day. At first, I wanted to go to Lacoste, a place known for its echinoids and gorgeous white scallops, but it turns out these quarries are no longer accessible. So instead we went to Carniol, which was a little further away. After only a few hours in the car we arrived at the village of Carniol. "Village" would still be considered being generous: there are no more than a dozen or so houses! And most seem abandoned too... There are two clay exposures on either side of the village, on the side of the road. They aren't hard to find, because the gray clay really stands out from the grass and trees. Both exposures are pretty much exactly the same. We started off at the first one.

Hi guys, I’ve done a bit of prepping of this ammonite I found in Salwick Bay, Yorkshire a few weeks ago and have no idea what it is. There are two obvious tubercles and there may have been more but as you can see it isn’t in great shape..

Found this at the Monroe Reservoir in Indiana on Monday. Looks like a brachiopod made of pyrite? Or is it more likely a cast?

Back in Oct. the Dayton Gem and Mineral Society had a field trip to the St Paul Stone Quarry in IN. Waldron shale. I've been slowly prepping my finds (along with other stuff) and finally completed my task. By far the most different piece I've found in a long time....a Rafinesquina-type brach covered in a bryozoan, with a Calymene face sitting on top, surrounded by pyrite. Size = 1.5" W x 1" D x 1" T. A complete, 3/4 prone Calymene. About 1.25" long. Some complete gastropods, all whose brown "shell" is pyrite. Some gastropods that aren't pyrite. A few brachiopods. Some crinoid calyxes. #7 Some some small pyrite brachiopods. And some tabulate corals.

I’ve been slightly obsessed for a long time now with finding a Whitby cannonball nodule good enough to put the hours of prep work into. I have given up while trying to split many, I have split a lot of empty ones, I have chipped a load while trying to split them. I do have a nice eliganticeras nodule that could potentially polish up but the shape just doesn’t lend itself. I found this at the weekend at Runswick Bay and while it would have been nice to have a split nodule with the positive and negative, I could see the potential in this. The actual ammonite is just a crushed up pyritey mess, but there’s a lovely shiny impression lurking below. So far I have uncovered around half of the impression on top and polished up a very small patch on the side, but it’s slow going. I’m trying to avoid using any power tools for the polishing (because dust) and have a decent selection of wet and dry paper (down to 600 grit). I was wondering if anyone with experience of these cannonballs could tell me how fine you need to go with the wet and dry to get a really nice shine, or if there’s something beyond that I should use?

Hello everybody! In continuation of the Frozen Fossils and Frozen Fossils II topics this report covers fossil hunting in real winter, with excavating fossils from under the snow (@JamieLynn might be interested). The trips took place this week when we had a thaw with temperatures raising to +1-2 Celsius after a long period of frost (so that digging became possible). This time I visited the same site as in FF2, which is MUCH poorer than the one covered in FF1, but MIGHT yield more diverse fossils (which was unfortunately not the case).

These are two of my favourites, which I have been working on with my dremel to remove matrix. Parts of both show a fantastic golden pyrite. Sorry the pics don’t show it too well. I suspect the gold is fading however. A few questions: 1. Can I do anything to bring out the gold? Would polishing with a wire dremel head help? 2. What can I do to preserve the gold? Should I coat/seal them? Thanks in advance!

Ive seen pyritized plueroceras ammonites that look golden, like this one, but there is also this one that is the same species from same location with same pyrite but not as shiny, is the difference just one is polished and one is not? Thanks for the help

Found on limestone river bank in Alabama. There were fossils nearby (shark teeth, shells, some kind of vertebrae) but not exactly where these were found. Can’t see in the photo but there are tiny gold looking flakes in it.
