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.

My grandmother (rest her soul) was a high school science teacher way back in the day. She was also a SERIOUS rockhound. These days her extensive collection of odds and ends lives in the family attic. I was going through some of the boxes when I stumbled on this gorgeous pyrite encrusted brachiopod. Unfortunately many of the tags and labels for her pieces haven't survived into the present day, so I've been curious about what species this is and where it might be from. I've heard that Ohio has a deposit with lots of pyrite fossils and brachiopods. Anyone know of any other places where such a fossil might have come from, or is Ohio the most likely?

Hi there, I found this specimen on a hike outside of Denver, Colorado. It was laying in the middle of the trail. It’s about 10cm long. It has grain that looks like wood or layers like mica. It’s also gold and shiny like pyrite or mica. It’s layers are wavy and it leaves a gold dust behind when handled. It’s stunning when the light hits it. Hoping to identify what it is. Thank you! Lisa

It appears to me as a pyritized wood, it gave off the metallic sheen when it's under the light. Pyrite/marcasite are abundant at where I found this and it's from Kiowa formation (Albian). Kiowa formation is primarily an estuarine and shallow sea environment, fossilized wood and plants are occasionally found from there. I found it as a concretion but it crumbled into tiny pieces when I pulled it out of the ground, so this one is the largest and only piece I have now. Do you think it's a pyritized wood?

In 2013 I was visiting around Buffalo and went to a creek that had been recommended. I didn't come across any trilobites but did find other exciting things. Among them were quite a few pyrite nodules I dug out of the creek bank. Must have found 30 of them. All rounded but varied shapes. About the size of a quarter or a little bigger. I have learned that many people have found them. Some close-ups. Many have a hole in them (shown above) and you can just barely see something inside the hole. Early on I broke some of these open and found... ...pyrite fossils. Gastropod, brachiopod, clam, ammonite. I quit there, I didn't want to smash them all. Over the years, as many who have found these know, some of the nodules began to decompose. What some refer to as "pyrite disease" or "pyrite rot". I have had a number that have broken apart and then turned to dust within a few years. I quarantine those that show signs but haven't had to in the last year or so. I have stored most of my nodules by simply putting them in a sealed container with a desiccant packet, with only a few problems after 7 years. But some ...the first 4 pictures of the post... I keep in a Pyrite display case and they have never shown any signs of problems. And the mini fossils have also never shown signs of decomposition, either. And they are on display as well, not packed away with a desiccant. So...some from the same "batch" decompose while others don't. Why??

New Jersey Cretaceous Pyritized Lignite Prep
The Jersey Devil posted a topic in General Fossil Discussion
Hi everyone, I would like to hear any recommendations for prepping pyritized lignite. I am about to try the PEG technique that @LoneRanger described in this topic: http://www.thefossilforum.com/index.php?/topic/19304-preserving-lignite-fossils-with-polyethylene-glycol/ This should stabilize the lignite. However, I don’t know if the pyrite will also stabilize. I don’t want it to develop pyrite disease. Would the PEG coating be enough to protect it from air humidity? Thanks a lot! Here is a sample of some of the material I am prepping: -
From my farm pond dig site. Brachiopods with pyrite. 70 MM. 2 views, Allegan County West Michigan. Plus 2 more one week ago.

2 inch by 1/2 inch with Crinoids, Bryozoans, more and did not expect to see the 3/8th inch 0.9 cm pyrite on it. Allegan County, Michigan From my dig site Yesterday. I believe it is limestone. Would like the approximate age for the fossils and about when did the pyrite form on it?

Last week I found what I think is pyritized wood from Pit 11. Is this the case? And if so, is there anything more scientific I can call these specimens? 1) 2)

Collected in 1994 in Cropwell Bishop Nottinghamshire UK, some Rhaetic pyrite layer pieces from a Gypsum mine. Packed full of bivalves, fish teeth and coprolites. Focusing on this particular find, would anyone know what it may be (1st picture) 1mm scale.

Leicester Pyrite Member. This layer between the Windom and the Geneseo black shale represents a sea of death. I find very few types of fossils in this hard to process layer of solid pyrite. Well preserved cephalopods and Placoderm armor (Placodermi is a class of armored prehistoric fish) are the most common fossils found. This very thin horizon can be easily found in the outcrop if you just look for rust dripping down and staining the grey shales below this pyrite layer. Every year or two, a piece of Leicester Pyrite will fall from its position high up in the outcrop and slide down to the creeks edge. It takes a lot of work to process the pyrite for fossils. Every blow with your hammer delivers the strong smell of sulfur and a ton of sparks. The reward for all this patience and hard work are fossils preserved in brilliant fools gold. This unit is also the only rocks in my area that routinely contain the armor of Placoderm fish.

Okay, Fool's Gold and Sand Dollars, but hey, I prefer those anyways!!! So yesterday was my birthday and I had a 6 hour drive home from a convention I was working and thought, hey, I'm KIND OF close to a fossil hunting spot I had heard about so I took a short (two hour) detour to check it out to see if I could find anything. And oh my goodness did I. This is a very very small grown over spot in East Texas, down a back road. I came across this beauty first thing but left it since it was too shattered to try to retrieve, so it sits in situ as it should be. I hope nobody ever disturbs it. So this was my take home beauty -it's about 30mm (slightly bigger than a quarter). Happy Birthday to me! And the Gold: Fool's Gold! Athough it wasn't TECHNICALLY on my birthday, I found these last week, so close enough. I had been poking around a creek, hitting it in different spots to see what I could find and stumbled up on a stash of Pyrite encrusted Illymatogyra oysters! I had heard there were pyrite "ammonites" In this creek, but the person I think was no quite sure what they had as there were no ammonites, but hundreds of these amazing things!!

Went to a beach in the Whitby area today, it was very slim pickings until my daughter saw the first of these items shining amongst the rocks. I’m guessing some kind of pyrite bivalves? The second item is something I saw on our way off the beach, am I right in thinking they’re crinoid stem sections? Thanks in advance

This is my current labelled collection. I have other stuff that I found on a fossil hunting holiday in the South West of England, but I’m very amateur so I don’t actually know the scientific names for a lot of them. Everything on this shelf was found except the teeth on the left and right, which were bought on the Isle of Wight. Essentially everything on this shelf was ID’d by members of this forum, except the pyrite and favositid, which were ID’d by friends, and the igneous rock and ammonites, which I didn’t feel i needed to have ID’d. The ammonites are my pride and joy, very detailed.

I recently acquired a collection of assorted rocks and minerals. Many of these specimens are from the 70's, 80's and 90's ( am in the US). In this group there is two ammonite in matrix specimens. I believe they are Russian due to them being pyritized. I am having a difficult time finding info about what species and what value these specimens may have. I go to the Tucson show every year and I don't often see ammonites like this. I was told to come here to find the experts! Thank you for your time, I look forward to posting more now that I am a member StoneAgeQuarry

Does anyone have any tips or tricks to preserve pyrite fossils? How to clean and keep them shiny without decay?
-
Hi to all, I've been trying to find a positive id for this one for some time now, my guess is that it could be a partial conical shell with remains of the animal still inside it. The inner 'shell' and contents are pyrited (iron), found in Wiltshire,England in a predomately chalk and flint with a very thin topsoil area, iron pyrite nodules are very common in this location. Than you Tony

I have recently begun my journey into fossil prep, i'm using a dremel electric engraver as it seemed to be the best cheap tool. I have several ammonites from Yorkshire within nodules - these are very hard in the centre and consist of pyritised sediment. It is taking a very long time with the dremel using tungsten-carbide point, so just asking for any advice on how is best to try and get through these very hard bits. Cheers in advance!!

Not sure if this belongs here or the minerals topic, but I would like help with preserving pyrite. I have a fossil from Penn Dixie that has some nice pyrite on it, don't know if the stuff from this location falls victim to pyrite disease but I am looking for a way to prevent it. Any tips are appreciated, Thank you.

Hi, yesterday I found a chunk of dinosaur bone at compton bay. Should I be worried about it crumbling because it has pyrite inside it?
