  1. I recently aquired a ichthyosaur jaw from lyme regis that was origionally purchaced around 1990. The piece has pyrite growth and lots of fractures. I’m guessing theres nothing i can do about the pyrite because it’s such an old piece and it’s already there. but how should i go about how fragile it is? Would a tiny bit of super glue help at all? Or should i just leave it because it’d do more harm than good.
  2. Pyrite and Hematite Fossils

    Hi there, guys. I've been learning a lot from you in the past few days and now I got another doubt. Found the following fossil is the auction website and it kept me thinking. Is this fossilized that way? I mean, I do believe they are real fossils, but were they fossilized by pyrite or hematite or were they treated somehow and covered with the mentioned metals? They do look pretty in my opinion, but if they are a result of a natural process (what I don't believe) that is even more amazing!! Just wanna hear your thoughts. Thanks in advance, Juliano
  3. I found this unusually shaped lump of pyrite in Charmouth UK (Jurassic) and am wondering what it will look like inside. Here is the lump in question: I recently split the below lump, found in Folkestone UK (Albian), And this is what it looked like inside: Will I get a similar result with the new lump as with the old one or would twatting it with a hammer be a waste of my time?
  4. NJ Cretaceous? Pyrite

    Hi everyone, I know it is possible to find teeth with pyrite attached to them in the Jersey brooks (which yield mostly Cretaceous material). I have never seen just a chunk of pyrite come out of here before, however. The pyrite piece below is from a NJ stream - would you say it is in fact from one of the Cretaceous formations present here? It is about 1 inch. Thanks for any opinions!
  5. Pyritized Ammonite

    From the album Fossil Collection

    This is a jurassic ammonite from the UK that has been mineralized by Iron sulfide - pyrite.
  6. Pyritized Clam shells

    Question for the group: is it common for a clam shell to pyritize in contact with a clay? This was from Edisto Beach SC. They were buried in mud to where they are not pyrite. I am assuming the clay is heavy in iron sulfide. Douglas.
  7. I found a block packed full of bone afew week back, but also full of pyrite. I thought it was just full of fish bone, which is quite common and i often leave it but luckily shoved it in my bag. Yesterday I picked it up and decided to have a dig around in it and was pleasantly surprised to find some ichthyosaur verts! So i suspect it's a mix of fish and Marine reptile, or just all ichthyosaur (Hopefully) Does anybody have any tips for prepping bone in pyrite. I'm probably just going to have a dig around and see what i can uncover, smooth it down with the dremel and add some coating to the bone to bring it out. It's Good practice for me but it's wearing my pen tip down haha. Hopefully there will be more verts to find! There's certainly more space to uncover more. Vert cross section on the bottom Ribs? on the bottom
  8. Pyrite fossil care

    Does anyone have any tips for bringing back the shine to pyrite fossils? I have some that barely have any shine left, but have seen pictures of them at full beautiful golden shine. How can I remove the tarnish and beautify them again?
  9. Why are pyrite fossils small?

    Hey everyone, I've been wondering why pyrite fossils are almost always small compared to others of the same species. does it have anything to do with the way the fossil is formed or is it something else entirely? thanks in advance!
  10. Hi I have a question regarding storing and safely displaying a pyrite fossil. I have read a great deal about pyrite disease so I know that's something to be carefull of and I have read you best keep them away from humid and store them in an air-sealed container. And now that's where I am heading with this question, what is all considered as a possible air-sealed container? I am currently keeping my pyrite ammonite (Pleuroceras Spinatum from Buttenheim in Germany) in a small transparent box as seen in the photo below, but is this good enough? Is this air-tight and will this protect the fossil from possibly falling victim to pyrite disease? Or do you guys recommend other ways to display it? Safer ways... Than the second part of my question... Some might already read that I am currently working on a new fossil room, and since it's nearly finished I was wondering wether it was safe to house pyrite fossils in said room when I take some precautions. Cause along with my fossils the room will contain 2 aquaria: one freshwater aquarium with my Polypterus retropinnis, and one brackish water with my Gymnothorax tile. (Also before transforming into a fossil room this room used to be one of the 2 aquarium/terrarium rooms in the house and it contained at one point 12 aquaria and we never really experienced problems with moisture.) As precautious measure I was planning to add a small dehumidifier just to be safe, but so my second question. Would it be wise to house a pyrite fossil in an air-tight container in this room even if it has a dehumidifier in it? And should you also recommend me to preserve the fossil in some paraloid on the fossil, I still have a bottle with 100 ml of paraloid. I would like to hear your opinions on the matter. Which container to use? To preserve it with Paraloid or not? And if I can move it the to new fossil room or if I should leave it in my old display case in my living room? Thank you in advance!
  11. 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.
  12. A few things from colombia

    I have been mostly caving in Colombia but stopped on a mountain creek to mess around for about 20mins. I need to get more pics of our haul but this is pretty cool (or I think so)
  13. Oddballs from Carniol

    Hi all, Here are some fossils I found at this summer in Carniol, and I would like to know what they are. If the species can be said that would be fantastic. So, the fossils are all from Carniol, France. They are from the "Gargasian", of the Aptian stage of the Cretaceous, some 120'000 years old. Looks like they're all pyrite-replaced. I believe they're some kind of cephalopods, but I'm really not sure. What are your thoughts? Thanks in advance! Max
  14. Pyrites fossil

    Can anyone identify this? I found it a few years ago on either Lyme Regis or Charmouth Beach, England. I believe it is preserved in pyrite and it is very smooth and symmetrical. I've asked others before but as of yet no one has identified it? I wondered if it was something to do with an ammonite as I often find them preserved in pyrite...
  15. Megs inlaid with pyrite?

    Hey All, Up to this point I have mostly been personally hunting for megs and whatever other fossils Calvert Cliffs will offer. However recently I have been searching online to purchase a few larger megs that are not possible for me to find. One thing I noticed is there seems to be a growing number of megs "inlaid with pyrite". It gives the fossil a gold/silver/ appearance. on the enamel. These megs are not typically cheap or small. There are many 5 and 6 inch megs with pyrite and I see some selling for $1,000 USD +. My question is: nothing about the "inlaid with pyrite" is natural, right? It is essentially "restoration", like polishing? And second, to each their own, but are people paying a premium for this "look"? Or is it mainly a way to restore/disguise damaged teeth? If the megs are selling then good for the vendors however I understand restoring or even polishing teeth (as long as the vendor is upfront). But I just found the pyrite be an odd practice in the world of megs. Thanks!
  16. Hi all, So a few weeks ago now I went to the location Carniol in France to look for fossils. And we found lots! Most of the finds are pyrite ammonites, but we shouldn’t leave out all the belemnites and little shell steinkerns we found. All the fossils are from the Aptian stage of the Early Cretaceous, and apart from the belemnites all have been replaced by pyrite. So I've already taken out all the belemnites and rinsed the clay off of each one (they’re looking gorgeous right now!), because their shells are not made of pyrite (and seem not to require any special treatment). By the way, does anyone know why only the belemnites are not replaced by pyrite, while all the other fossils are??? But now comes the question of all the pyrite fossils. All are very small. Some were found already starting to “rust” (I suppose this is due to pyrite disease?), but most are still in good state. Nearly all are still partially covered in dry clay though, and (just like it did with the belemnites) I suppose it will come off very easily as soon as it comes in contact with water. But, here is where I am a little worried: Rust is due to the oxidation (—> oxygen) of iron. And in water there is oxygen too, and more of it than in air. Therefore I’m scared that rinsing the pyrite fossils will accelerate the process of pyrite disease and make them “rust” more quickly. So what should I do to clean the fossils? Is it okay if I simply rinse them off? Or is that a no-go? Or maybe I should do it in a special manner or with specific substances? And, finally, what do you think is the best way for me to handle these fossils so that they “survive the pyrite disease” the longest possible? I know that there are a few ways with some weird chemicals to treat them, but I’m only a kid with limited equipment, money and experience, so I’m not able to do anything too intricate or acquire very funky chemicals. I’ve also read that apparently there are two different types of pyrite? How do I know which one my fossils are, and is there anything I should know more about it? Thanks in advance for your help to all those questions! Max
  17. I have something of a cephalopod hash plate from the Britton Formation in Collin County Texas that I am working on. I don’t have great tools and so I’m prepping this completely manually, by hand. It has a layer of pyrite that is pretty tough to work with by hand. I am wondering, could I use Iron Out to soften or remove the pyrite without doing harm to the fossils or the cohesiveness of the plate? If so what would be the best way and dilution to use it at? These are pics of the little plate. I consider this the bottom. You can see the thin gray layer here and there. I’ve been slowly chipping away at it. Maybe I could brush Iron Out just on the spots of pyrite. This is the top. It has a bunch of little ceholopods on it. There is a mix of heteromorphs, baculites and ammonites along with some tiny, adorable gastropods. This pic it is partly wet, but the pyrite is covered with a red mud on the left half and top half of the plate. The bottom is a bit easier to work with since the cephalopods aren’t packed like sardines as they are on the top side. I can probably get rid of most of it on the bottom without too much damage, but the top is another matter.
  18. Found my best Psaronius sp.

    Just wanted to share the beauty of this recent carboniferous find. I just sliced this yesterday. It still needs some work and i need to finish the other half, but take a look at the vascular cell structures of this fern tree (psaronius sp.). There is pyrite throughtout this piece, giving it a real luster (it's hard to see in the pictures).
  19. Hi all, So after learning of the inaccessibility of the location Lacoste, I was wondering if there was maybe another location nearby. On Fossiel.NET I found the location Carniol, which looks very promising! https://www.fossiel.net/sites/fossil_site.php?plaats=148 Anyone got any tips on how to best find fossils and bring them home? How to look, how to take the fossils out, etc? Any tips or comments would be greatly appreciated! Thanks in advance, Max
  20. I bought this ammonite online, found in the gault clay of Folkestone, Kent, and it has some unusual markings on it. I can't tell if they're from before or after death or if they might be bite marks. There is what looks like a pyrite deposit in the dent and I was wondering if anyone could tell me more! Below are some pictures.
  21. Non Silica Fossil Wood

    Here is a very recent paper about wood replaced/fossilized with non silica minerals such as zeolites, pyrite, dolomite, fluorite, copper pyrites, apatite and more. The numerous color photographs make this paper a winner. @Fruitbat A good one to add to your great collection. http://www.mdpi.com/2076-3263/8/3/85/pdf
  22. coprolite or only pyrite?

    I have found this pyrite piece With a very strange shape,is it only pyrite or ? coprolite?or?
  23. Can someone explain a process...thanks.

    I have been watching comments about pyrite for awhile, and have shown my sample, in situ, along with two orthocones that would be nice to identify. they are from a Northern Wisconsin quarry about 15 miles due east of Green Bay. When I first started looking for fossils around my home town, I was told there weren't any because the glacier scraped away the material...since then, i have learned there are fairly large swathes of geology that do contain wonderful fossils...most often found from quarries, where the Glaciers didnt scrap deeply enough to affect them, or from areas possibly missed as in the makoqueta shale near Green Bay. At any rate, what I am interested in is the process by which the pyrite is formed. Does iron seep into the crevice for a fossil was formed, or is the iron actually from the body of the animal itself. For example, in the conesauga shale trilobites ( which are all wonderful by the way) many impressions are surrounded by a circle detail left from gasses that leached into the surrounding area...are these iron oxides from the body of the animal also...and are they therefore considered some form of fossil as well? Thanks for the knowledge, in advance. (the pyrite is about 2 inches across, the deep ridged impression about 6 inch long, and the orthocone about 18". It was my first fossil trip in the area and I had no measuring tools along. The large orthocone was in a block of about 600 pounds or it would have been coming home with me...LOL>
  24. Pyrite

    I have a sand dollar that is mostly covered by pyrite. It still has most of it's luster. I have read about pyrite disease and am wondering what I should do to help preserve it. I have also read that having pyrite in the fossil showcases my affect other fossils. Is this true? What should I do to bring back some of the luster? And how would be a good way to seal it to prevent the turning or ruining of the fossil and others?
