  1. Cracked nodule repair

    I am after a bit of help please. I have a fish nodule with a crack that has separated. How do I go about repairing it? I can either attempt this myself. What glue/joining agent do I use? Is this straight forward? Bearing in mind I have never attempted this before. I would also be open to having someone knowledgeable do this for me. If it doesn't end up costing me a fortune. Does anyone in the UK know of someone reliable. I am at work. Will post photos later Thanks
  2. Plant ID

    I recently purchased this nodule (about 5cm in length) with a Bothrodendron twig. There was also the cup shaped inclusion Any ideas?
  3. Hi all, I have an ammonite specimen from Folkestone, UK that is locked in a phosphate nodule. Is there any way for it to be removed? Thanks, Jay
  4. Thought this would be an interesting one for anybody overseas, who has never heard of Yorkshire’s Golden Cannonballs. Theyre only found in the UK along the Yorkshire coastline. With a 1/15 chance of having something inside, it’s safe to say they can be quite rare, and are always sought after. More often than not, they either contain one, or multiples of Eleganticeras ammonites inside. I’ll never tire of finding them. Theyre found in the shake jet rocks, and take hours to polish up the iron pyrite to give them their golden glow of you like. Here’s one I recently prepared.
  5. After the last one (link here: fish skull ) turned out to be a nice skull, I'm wondering if anyone could ID this bit? It's very 3D and hard to photograph without image stacking so I've given three views. Phosphatic nodule, Brigantian (U. Mississippian) marine shale, Co. Durham, UK. counterpart:
  6. large chert nodule

    I'm currently working with a monster nodule. 14.5 inches around. Had some chipping at the bottom with a small amount on one side. After several freeze/thaws the whole lower section is now exposed from chipping & flaking with the smaller area on the side enlarged as well. Nice off white, almost powdery exterior with a med dark brown interior. I'm hoping there's at least something in it and that the something is larger than a pea. Nodule has this tiny, curious almost nipple like area on top. Anyone have any experience with one this size? Am I possibly wasting my time? There are several hairline cracks showing here & there in the white exterior so far. My biggest problems are that I don't really know how long I should be soaking it, or freezing it or if it needs to be submerged in water while freezing. And of course, if I'm going to make it the whole way or end up whacking it with a hammer. Any helpful suggestions would be nice.
  7. Flora or Fauna?

    Another nodule I found already split. I thought it might be plant matter because of the dark color but the shape reminds me of a lamprey picture that I can no longer find. Probably wishful thinking and imaginative viewing.
  8. Mazon Creek Bone Fragment?

    I found this nodule already open and thought it was a fossilized piece of wood. However, it is not the usual black color of most of plants I have found. Could this be a bone fragment?
  9. Latest acquisition - fossil capelin

    From the album Purchased/Gift Fossils

    Fossil fish nodule from the Lower Pleistocene of South West Greenland. Mallotus villosus.
  10. started prep on another crab nodule hope there's a big one in there fingers crossed
  11. Madagascar Fish

    @oilshale, any idea what species is this Madagascar fish? Only this half of the module is available, and it’s broken.
  12. What do you make of this?

    Recieved a bundle of Mazon Creek nodules and found one I can't seem to ID. Object is 3cm across and comes up to a shallow cone shape similar to a very old volcano/cinder cone. Any ideas?
  13. Crabby Concretion, Product of Texas

    I felt industrious a couple weeks ago and cleaned up the fossil barn, flushing a couple unprepped Maastrichtian Dakoticancer concretions out of hiding. I guess I went on a harvesting spree as houses dropped on the old site. Anyway, prep started with little exposed, and except for a chunk missing out of its butt, this isn’t a bad crab, esp ventrally. I didn’t take pics at the beginning, so this photo sequence starts somewhere in the middle. It’ll keep.
  14. Lingulid ?

    Found in an Emsian marine formation in northwestern Maine. This nodule, or concretion, is considerably darker than most found nearby. It was also in a layer with an accumulation of shells, where as many of the fossils are horn corals dispersed more randomly in what I think is muddy sandstone. Would this be a phosphate nodule that preserved a Lingulid ?
  15. Ironstone Fossil Stability

    I found someone selling a few Bolivian trilobites in ironstone nodules and I really like this one (above). Most of the others have an oxide coating (example below) and this one does look very slightly yellowish. Will it (or other fossils in ironstone like those from Mazon Creek) be stable long term? I don't really want to buy it if it will just rust away.
  16. Two Mazon creek pieces

    I have these two Mazon Creek pieces out of a big group that I picked up, and I am a little at a loss to figure out what they are. The others I was able to figure out generally, even if not a specific species, but not sure on these. Any help would be great!
  17. Beginner prep tools

    I would love to have a go at prepping some nodules, because the hammer and chisel is pretty brutal. What would i need to set up an airpen? and would it work on Yorkshire fossils? If you have any recommendations for a beginner set i'd love to hear your ideas. Thanks
  18. What is this cluster of nodules?

    Found at Brownies Beach, on the Chesapeake Bay in Maryland. Never seen anything like this. What is it?! The 30+ nodules are very hard material like enamel, and the base is bone material. Can someone please help identify this fossil?
  19. I bought a bunch of nodules to practice with my hammer and chisel. This one seems to have two different ammonites in it, or is it just one fat one?
  20. Just thought some people might be interested in a quick look at this. My wife found it lying on the beach at Charmouth several years ago, after a bunch of experienced collectors ahead of us had the misfortune to walk right over it. It's just come back from being prepped by the excellent Craig Chivers. Here it was after I'd attempted my own prep on it, and rapidly gave up. The nodule was heavily pyritic, the ammonite had delicate spines, and I felt that it was beyond my level of expertise. Here it is today, back from being prepared properly. It's a battered old ammonite, with a crushed body chamber and a centre that was badly beset with pyrite, but I do love ammonites that have character. I haven't been to Charmouth for years, much to my regret, but this is definitely our best ammonite from that location. No idea what this weird impression is. It looks a bit too rounded to be fracturing from the body chamber being compressed, but any thoughts welcome.
  21. Flat worm? Tully monster?

    A nice old gentleman gave me a bag of fossils he gathered at Mazon Creek many moons ago. Unfortunately he didn’t bother identifying most of them or even double checking that the rocks actually contained fossils at all. So I’m left to sift through them and figure all that out. Here’s one I’m having trouble with: Now, don’t any of you be getting my hopes up by saying that it’s part of a tully monster, lol.
  22. Moroccan Cretaceous fish

    I was told this fish nodule came from the Anti-Atlas region of Morocco, and is supposedly Cretaceous in age. Can anyone ID it?
  23. Worm?

    I found this nodule last summer and opened it about a month ago. Could it be a worm? I didn't know if the two adjoining dots on the left were jaws.
  24. I went exploring today. I hit 3 places. The 1st two were the Ozan in Rowlett. The first 2 were a busts, but the 3rd was in the Eagle Ford in Dallas and it was a very interesting place. I can’t say that I found specific fossils per se, but I did find the product/remains of prehistoric animals. I was ecstatic with my finds. Septarian nodules have been on my bucket list of things to find. I found a hill full of them!!! I got there less than an hour before sundown and was thrilled with what I found. This one is very cool, but I’m not sure what the original creature actually was. The only thing I can think of is that it was an ammonite and maybe the septa became crystal filled, but that is a total guess. The curves on the edge and sides don’t look right, but I’m not sure exactly how these formed in the particular area. It honestly looked like the badlands or something desolate with nothing growing there and was a very fine soft gray shale. I found a lot of what I think are aragonite crystals at the site as well as some other beautiful crystals. I have never found any crystals in this form before. So I’m thrilled and hope to go back tomorrow if I don’t get paged into work tonight. This is the one I’m very curious about. Maybe some of you may have seen something like this before, but I have not. I think it is super cool though. I’m pretty sure it was once a critter of some sort. I believe it is a septarian nodule, but there are no septarian marks externally like you usually see. When I was washing off other nodules I found, as I was washing, the exterior began to slough off and the septarian lines became visible. There are basically 7 bundles of crystals across this thing. Some are kind of merged. #1 This one has me most curious of all. #2 other edge. Right edge is encrusted with what I guess could be considered pyrite disease, rusty material mixed with crystals encrusting it. I have found an ammonite before that was rusty with crystals like this. #3 Close up of the encrustation with small crystals jutting out. They’re hard to see. #4 one side. The other side is less descript. The curve on this doesn’t look ammonite to me. I found some pieces that looked almost turtle like, but I don’t know turtle stuff when I see it. I will say the rock material is soft and is a fine shale like texture and material so when wet it becomes slick almost like soap, but no bubbles. This is a 2nd find in the same area. In the center below the crystal on top is a sea shell. Wish I knew what kind, but not much is exposed. All you can see is the mother of pearl inside the shell. #5 note crystal branching in 3 directions below shell, there is also a beautifully formed crystal on top that is pristine and wafer thin that was part of the septarian, but the non-crystalline material has eroded away leaving the flower petal like crystal. #6 This is it from another side. You can see more of the septarian sections. If anyone knows the critter this arose from or the crystal type I’d like to know it. Calcite and gypsum are most common here. There is brown too. I also found stone with green crystals. This is a 3rd find in the same area. #7 I found these bars just laying on the ground like this. They looked so peculiar. I couldn’t figure out what they were. I thought they looked a little like columnar basalt, but knew that wasn’t it. There was a small nodule in the ground less than a foot away that was cracked all over and filled with crystal. I wanted to dig it out. In the process of digging it out I found another hard object just under where these were. I thought it was a solid rock, but when I started to move it the rock came apart in these shapes. #7 cleaned up a little at home. #8 one up close. I believe they are all covered in aragonite or brown crystals. I’ve been told that when an ammonite is encased in a nodule and then the mineralization process takes place that often aragonite crystals form as a result from the nacre in the ammonite shell. I have not found the source of that claim though. Can anyone tell me how these formed and what the crystal is? Is it aragonite? How would I know? I can provide higher resolution pics upon request. I had to make these low res to get all of them in here. @Uncle Siphuncle, @Fruitbat and @BobWill you 3 have hunted the Dallas and North Texas area for many years. I assume you’ve seen these sorts of things and may have insight you can share.
  25. Alright everyone I'm pretty excited about this one. It's about an inch long and 1 1/2 inches wide.
