  1. Unusually smooth nodule

    I found this half of an open nodule last September when I was hunting at Mazonia Braidwood. It was covered in dirt so I took it home to see if anything would show up when I cleaned it up. The dirt rinsed off easily and I was surprised to find a layered, smooth surface on the inner half. The feel and patterns of colors remind me of the inside of a shell. Has anyone seen this before or have any ideas about what this is?
  2. Fern ID

    So I got this Fern nodule yesterday. It came with no info. Approx 6 cm Any ideas?
  3. What is this please?

    I found this today at walton on the naze. Does anyone have any idea what it is please? I dont think this is just a concretion or anything looks like all little bones or something?
  4. Unknown orthocone

    So I have partially removed an orthocone from a nodule that I found in some eroded glacial till. The rock is most likely silurian in age but I can't don't recognize this orthocone. It seems to have faint striations running lengthwise down the shell, which I haven't seen before.
  5. Howdy all, I tried searching for answers on the search bar, but couldn't find anything, so I'm hoping someone can help me out. I was going through the fossil prep section and noticed that many people seem to start off with a large nodule and remove all the matrix to reveal the fossil hidden inside. My question is, how does one (a seller, or person out on a fossil hunt) even determine that a big hunk of nodule has a fossil inside if there are no immediate visible indications of a fossil from the outside? Once again thanks.
  6. Unknown Mazon Creek

    Hi! I just recently found this piece for sale, with no identification. The bumpy texture made me think of Arthropleura, but could also be something like a Stigmaria root. Please let me know what you think!
  7. I have a few nodules that haven't split from my Mazon Creek trip in early March. They have been through I'd guess 20-30 freeze-thaw cycles by now. I have been getting impatient, so I decided to whack them with a hammer and chisel. I've smacked each of them like a dozen times, but they still won't split. It's not obvious where the bedding plane (?) might lie, so I've struck them from all sides to no avail. Is this an indication that there is nothing inside, and therefore no bedding plane?
  8. Are the fossil fish nodules from Madagascar offered for sale exported legally? Lots on offer on ones favourite auction website, and elsewhere. Seen a lot of discussion on Madagascan Ammonites for sale, how they may not be exported unless they have been “artistically enhanced” ie polished. But not seen anything mentioned re fish. Does anyone have any info?
  9. Mena Arkansas

    A friend found this along the Little Missouri River Just outside Mena Arkansas. I believe the area is early Cretaceous. My first thought was a Septarian Nodule. Is it that or something totally different?
  10. Ricky’s Mazon Creek thread

    Hey everybody! Welcome to my Mazon Creek thread, where I’ll be posting pictures of various Mazon Creek finds! I’ve been hunting there for upwards of 10 years, so I have piles of uncracked nodules just waiting to be opened. So as they open, they’ll find their way here! Feel free to jump in and add your own and keep this thread going! And I’m sure there are many that have gone unidentified, so I’ll probably need some help from the experts!
  11. I took my 8 year old on a concretion hunting expedition to the Lincoln Creek formation over the weekend, and we didn't find anything too great, mostly they contained this reddish brown crystalline mineral in various unidentifiable shapes. My son says he thinks this one is a fish, and I told him I didn't see it, but he said I should "ask the internet" because I "don't know everything," so I'm asking away! Any thoughts on what the mineral is that's inside these? It doesn't appear to be iron-based since it weathers pale, not rusty, as shown by the second photo. I forgot to include something for scale, but the rectangular faces of the broken concretion (left side of photo) measure about 5cm x 4cm.
  12. Hi I thought this fish was quite interesting but as the seller provides very little information and I see lots of composite fish I wanted to see what you guys thought
  13. 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
  14. Plant ID

    I recently purchased this nodule (about 5cm in length) with a Bothrodendron twig. There was also the cup shaped inclusion Any ideas?
  15. 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
  16. 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.
  17. 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:
  18. 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.
  19. 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.
  20. 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?
  21. Latest acquisition - fossil capelin

    From the album Fossildude's Purchased/Gift Fossils

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

    @oilshale, any idea what species is this Madagascar fish? Only this half of the module is available, and it’s broken.
  24. 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?
  25. 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.
