  1. Past hour
  2. A few Ordovician unknowns

    Orthid brachiopod looks like a good match. As for the genal spine, best guess would be Isotelus? Not seeing another good match on the Dry Dredgers ID page.
  3. Hello from ohio

    Has a sort of Silurian feel to it. Favosites would be a good guess but knowing the actual formation and age would help narrow down the possibilities.
  4. Dating Ammonite

    Hmm $10-20would be my guess, depending on the merchant. They are very common.
  5. Dating Ammonite

    Dunno if I can ask this is but what is one like this worth? I know hard core collectors would be far less the the average one
  6. Dating Ammonite

    These usually don't preserve/show the living chamber, or they are cut off in the polishing. The adhering matrix might have looked like that, but not the shell. .
  7. Looking for Donation of Sawfish Fossils

    Complete rostrums or complete body fossils would be extremely expensive. You can buy the Rostral teeth online at many on-line retailers. Good luck.
  8. Dating Ammonite

    Cleoniceras from Madagascar are generally very cheap and don't have much value but it is still a very nice fossil! The inside is filled with calcium carbonate or calcite while the outside is usually sanded and polished away on these ones. The pattern you see is the suture lines which separate different Chambers of the shell so the ammonite could fill them with air or water to make it sink or float. The end looks like it just has a bit of the matrix in it which would be the rock that surrounds the fossil when they are excavated but I do not believe the matrix can get into the actual shell which is why that is replaced by calcite. Hopes that clears it up a bit for you
  9. "splitting" really soft slabs

    Make sure you get your heat treat right or your DIY chisel can shatter when you strike it... not a pleasant experience.
  10. Bull Canyon Formation

    Incredible Finds!
  11. Dating Ammonite

    So this is what would be under the shell? Didn’t think it would have looked like that under there. I would have been expecting it to look like the grey rock matter you see at the end of it. So would this be like a inside skin? With no shell would this make it far less valuable?
  12. Dating Ammonite

    I picked this one up this morning, it was to nice to pass up and first one I ever seen local. My question is can you date these by the outer shell and how they are made up? Smooth or with ridges Etc
  13. Piece natural footcast fossil?

    Please be courteous, and post your requests in English. Not everyone has time to run your posts through Google Translate. This is an English language Forum.
  14. "splitting" really soft slabs

    Thanks, though I can DIY something in my own shop. So this started as a large slab with a visible trilobite. The opening post has a link to the trilobite pics and they show some of the rock surface. I have since hacked and smacked the rest of the slab, which tended to break into chunks or flake off. Here are pics of some larger pieces of leftovers. The junk heap has some more source material, but I'm really hoping to identify the source. Either way, I'll try to get my hands on more stuff to practice these skills on and hopefully find another trilobite
  15. Neato to the unth degree.
  16. Today
  17. My offering was shipped last week and I have received mine.
  18. Exporting fossils from portugal

    Aside from the collecting argument, there is a paleontology museum in Lisbon that is probably the best I’ve ever been to, worth visiting. Portugal has several track sites, impressive dinosaur displays, etc. If you love paleontology, or dinosaurs in general I highly recommend going there.
  19. Beautiful! With specimens this rare, it really makes you wonder what new species are out there, waiting to be found. Hopefully by me next March 1st! Chris

  21. Exporting fossils from portugal

    You don't get to have your cake and eat it too, as the expression goes. If I can't at least modestly collect in Portugal legally, than I will travel to a destination where I can. And that nation can have my money.
  22. Fossil sealant?

    I've been using Vinac for years. Dries quick, easy to remove. Great for the field and the lab. Makes a great barrier/sealant before molding an important specimen. I know there are some cyanoacrylate alternatives like Paleobond's Penetrant but they can sometimes be very difficult to remove. Everything seems to have it's place depending on what you are working on though.
  23. White River Oligocene Prep - Leptictis

    Today's work. I lightly sanded the previous putty work to get it into the precise shape and texture I wanted. I felt the fill in the lower jaw was the wrong shape afterwards and added a bit more putty this morning. There was also a missing flake of bone in front of the orbit which I filled. I'm choosing to forego the zygomatic reconstruction at the moment. I went through my collection and all 4 of my options only had right zygomatics. I'll put a request in to my collector friends to find me a left one to cast. Just don't think I can do it justice with hand sculpting. If all goes well with this drying, the plan is to put a little paint (lipstick?) on the putty tomorrow. Planning to use acryllic paint and blend my own colors. Closing in on the finish line!
  24. Exporting fossils from portugal

    They want your turism... Don't want you collect fossils
  25. Black flakes coming off buffalo skull?

    I don't prepare fish; but, when my Green River stingray started to "shed" fine debris, I sealed the fish surface with Butvar B-76. I first consulted the quarry owner/preparator to make sure the acetone solution would not conflict with whatever was originally used to prepare the fossil.

    Cheers mate! Might make it slightly easier for all!
  27. Some unknown commercial fossils

    I believe the gastropods and Brachiopods are from Morocco, or some part of north africa.
