  1. Hi everyone, so I have just gotten into fossil prepping and I'm practicing on some crabs that have some damage to them. Learning so much with each hour I spend! I made a time-lapse of the most recent one: https://youtu.be/kH33t4NklYk?t=675 (short version) https://www.youtube.com/watch?v=STw905QB570 (long version) It's still quite rough at the end, I need to smooth the rock out and I haven't tried to get into the really tight spots with my current tool - waiting to get something like a micro-jack.
  2. Strange colour crab claw

    A couple of hours in on our fossil hunt at Glen Afric, I spotted another crab fossil! This had now been our 3rd crab of the day. We have not found a similar crab to this one. Any ideas or thoughts on why the colour is so strange?
  3. Having found my biggest crab yet, I was very curious about how big the Tumidocarcinus giganteus gets. It sure lives up to the species name giganteus! @Dave (POM) Allen has found a massive claw, the biggest I’ve seen. Could be from a huge crab too, but I’ve seen some really massive claws that are way out of proportion with the crab. I’ll have to dig out the photo from my computer when I’m home, but I have an amazing example of this. The Canterbury museum has the biggest specimen - complete crab I’ve seen There it is near some normal sized (but still much larger than Washington) crabs. I didn’t have any measurements on it, but when I visited Al Mannering to do some prep he had a replica and I asked if I could take some photos for reference. Check it out! Andrew Fear who is another regular Tumido collector has found this guy Don’t have any scale on it, but it is impressive! Love to see any other large examples, or even the other end of the spectrum like @RJB tiny Tim the Tumido
  4. Help a complete newbie

    Hey. So today on a whim I decided to give fossil hunting a go. Took my family to the beach at Glenafrik farm, about an hour north of Christchurch, New Zealand. About 30 minutes in I stumbled across this beauty (beginners luck huh). Now I’m wondering, what am I supposed to do to clean/preserve it? Also, my wife found what we think could potentially be a fossilised log? It is very heavy and to our untrained eyes, looks like a log with bark around it. It was quite different from all the other rocks in the area. What do you more knowledgeable guys and girls think? Again, any tips or thoughts on cleaning/identifying it?
  5. Massive concretions

    Hello I found this along a small spring fed stream in Gonzales county, Texas. This area has produced plenty of ice age fossils and was home to numerous boiling mud pits which ended in the late 70s due to oil production; not sure how relevant that it haha
  6. I’ve been in New Zealand for over a month and spent a lot of time on the coast famous for the big Tumidocarcinus crab concretions. Unfortunately my trip was mainly to visit my father who was ill and he passed away while I was here. Time on the beach has been a good distraction and helps to start the healing process. You might be surprised that I usually have the beach to myself and the solitude and sounds, sites and smells of the coast are a comfort. In terms of fossils it was my best trip yet, but this came from lots and lots of walking, boulder hopping, and early starts. Sorry pictures are large files since I’m doing this from my phone. So spread out in many posts. Day 1, was exploring new sections of coast, clambering over rocks the size of a bus with razor sharp shells. Found some nice concretions, but they were empty
  7. Ive been working on a most wonderful crab concretion these last few weeks and finally got to the grinding stage to smooth out the tool marks. While grinding at times I would realize a bad smell? About the 3rd or 4th time I smelled this smell I began to wonder what was going on? and no, I wasn't passing gas, (just to stop any of you funny business type fellows). My guess is sulpher? I noticed when i was prepping this crab that its got a bit of pyrite in it so the rock must too? Right? Has anyone ever experienced this? Can grinding on a rock with sulpher in it produce a bad smell? Its not a big deal but just wondering. RB
  8. Hi Everyone I have two halves to a concretion that contains a good size crab. What would be the best way / product to get it restored and ready for prepping? If there is already a thread, please point me in the direction as I couldn't find it. Thanks! @RJB@DLB
  9. I found a really good concretion a few months ago here in New Zealand and didn't want to try prep it myself as I am still very much a beginner. Luckily, @DLB was willing to help me out and did an amazing prep job - both sides! It's by far the best crab in my collection, and very well travelled after it's 24 000km (15 000mi) flight It measures 16cm (6.25") across. I made a video of me finding it, sending it off, and opening it which can be found here: https://www.youtube.com/watch?v=V4cqpVKsOO0 Thanks for the amazing prep job @DLB!
  10. Isle of Sheppey fossil

    Hi all. I went fossil hunting at the isle of Sheppey, Warden point. I found this one curious item, which I initially thought was a fossilised crab carapace. It is difficult getting the photos perfect, but I hope someone can help me ID what it is. Thank you, Nico Loubser
  11. Hi all, I recently got this crab as a gift from a Burmese friend. He said it came from the Rakhine State, western shore of Myanmar. He said his friend found it there. Unfortunately, neither of them kept any extra provenance detail about it. I can find no info whatsoever about this crab online. I don't think Myanmar fossils outside of amber have easily accessible documentation. This crab looks like it might be a Galene bispinosa. Does anyone know what species it is, and what age or formation it possibly came from? Thank you.

  15. NJ Crustacean Parts

    Hi everyone, I would like some help with 2 Late Campanian crab specimens found some time ago. The first is some type of crab claw. The second is a partial crab carapace. I haven’t been able to find anything that really matches them. They are both 1 centimeter in maximum dimension. Thanks for any help!
  16. I think this is a piece of a crab, perhaps the ”torso”? I found a paper with crabs from Kristianstad basin, but only images of claws, and it is not part of a claw from what I can tell? https://sp.lyellcollection.org/content/434/1/241 The crab in the paper is named Protocallianassa. What do you think?
  17. Decapod claw or pseudofossil?

    99% sure this is just a rock, but the shape just keeps me wondering... Found along the beach of Stratford Hall in Montross, Virginia on 7/6/19. Any thoughts?
  18. Crab?

    Found this yesterday in Medina County, Texas. Any help is much appreciated. Part of a crab claw or leg are my thoughts, but couldn’t find anything that matched.
  19. Well, I had another opportunity to hit the beach with the infamous Dr Mud... unfortunately not many photos this time, but we had had a tonne of fun... the Big D had a great day, I'll get some photos of his best finds up later.. but we sat down for a break.. you see that rock just behind him? Yep, it was a crab. A really sandy, flaky one but still another crab. @Doctor Mud - That big half I bought back to polish - it was a top not a bottom. As I cut it away it to flatten it - it all disappeared... We still came back with some goodies, and the big D got into prepping first thing this morning... He found a really nice black crab that he wanted to get into first, but I talked him into doing a pebble instead..
  20. Some of my collection

    Hello gang, As promised this is where I will share specimens from my personal collection, my grandfather's collection, and the collection that was donated to the university I work for. The latter is interesting as it is literally boxes of rock and fossils, with no information and my university does not have a geology or paleontology department. I'll be updating it every so often. Enjoy! NOTE: Some of the donated items have old school "labels" on them. If you see initials or such that you recognize, please PM me, as I am doing my best to properly catalog them properly as part of my job!
  21. A big crab leg and???

    I'm sure that the one long fossil is part of a crab leg but I can't seem to find anything on the web like it, all of the crab fossils I find appear to be your typical size crab such as the blue crab. This look like it would come from a very large crab. Came across what looked like other leg parts that appeared to be at least 6-8 inches. That second smaller piece, I don't have a clue. There's not much there to go on, just hoping that maybe someone will recognize the pattern on it and know what it belongs to. These were dug out of sandstone in which the bivalves and gastropods have been dated to about 2.5 million years old.
  22. Cool pair of claws

    Finally finished up this pair of claws I believe belong to some species of Raninidae, though I'm far from certain. The concretion does contain at least some of the carapace, but it's in pretty bad shape. It seems to be badly crushed and poorly preserved. So I decided to leave that part alone for now and just prep out the claws, which were just starting to weather out of the front of the conc. Some day I hope to find a more complete specimen, but for now I'm pretty happy with this cool pair of claws.
  23. So this material is from the Clayton formation in Arkansas. It is Paleocene in age. We are finding a lot of these flat pieces which I at first thought might be crab shells but now I think they must be scales from armored fish. Sometimes they are very thin and small - these examples are larger ones. If I am correct does anyone know if we can tell which fish they are from? (tape measure in view is in mm) The lone piece is from the same matrix as the others. After cleaning it up I would have guessed it was just a larger piece of armor but while I was removing it both ends broke off and it has some internal structures too. Also it seems to have tunnels that run through it that make me think of passages for nerves or blood vessels (bone? - it sure doesn't seem like it because it seems to have a shell). Here are pictures of its external and internal structures. The tube-like piece connects with one of the holes in the outside shell. I have taken pieces of all 4 exposed internal surfaces. It is not quite symmetrical which makes me think it isn't a crab . . . The fourth pic where a lot of the white matrix is visible is the back. I have been reluctant to clean it up since it is a bit fragile. Note: pics 5 & 6 (with the tunnel-like structure) have a bit of rubber cement on the surfaces - I had to retake the pics and had already begun to glue them back together
  24. Crab prep finished(for now)

    I recently finished this pulalius vulgaris and wanted to show it off. I may work on it more in the future when I get an air abrasive set up, but for now I'm pretty happy with it. It turned out well considering when I dug it out of the bank it rolled down the hill in two pieces. It was my first major repair and I have only prepped 7 or 8 of these. I think the practice is starting to pay off, but having a cooperative crab goes a long way. I know it's nowhere near the level of skill you see elsewhere on the forum, but I'm pretty dang proud of this one.
