  1. Hi All, I recently purchased this Glossopteris slab. It appears to be made up of multiple layers showing fragments of leaves Would any further prep reveal more detail or possibly entire leaves? Thanks
  2. What is this a slab of? (Lulworth)

    Lulworth is a late Jurassic to Mid Cretaceous area.
  3. What kind of fish is this? Inherited

    Let me know if you need anything else to help. It's rad! This thing is soooo heavy!
  4. I framed a pair of rock slabs recently, using a technique suggested by a forum member. I've done this before, and it has always come out well. I used Neilsen Metal Sectional Mouldings for the frame. I got the pieces custom cut by a frame maker, and just had to screw them together and add the wire. This technique works for slabs are fairly square or rectangular. There is overhang on the frames with will let you fudge a bit unevenness, but there is a limit. Neither of these slabs were perfectly rectangular and they worked fine. I used the N117 size frame, because it gives decent depth for the thickness of the rock slab and is also has a slim edge for these small slabs. I have use the N95 frame also; it is good if you want a thicker frame, such as for a large slab. Total price including shipping and hanging hardware for both was $26.61. Send me a PM if you want to know the online frame shop I used.
  5. mississippian fossilerous limestone

    Can anyone help me identify the vast array of specimens on this slab? I see some rugosa.
  6. Ichthyosaur stomach contents

    From the album Marine reptiles and mammals

    Cross sections of the stomach, full of squid/cephalopod hooks and beaks, of an early Jurassic ichthyosaur (Stenopterygius quadriscissus). One slice has the animals ribs, the lighter tan objects, around the stomach, while the other is entirely of the stomach contents.
  7. Fish Fossil

    It has been a while since I have been online. So this is one of those very unhelpful posts where I know very little about this fossil's origin. It was purchased in South Africa and the slab is very well preserved. I am hoping this is not a fabricated fossil because the detail is exquisite. This is also a chance to show off my new Nikon D810 camera. I will answer any questions to the best of my ability.
  8. I helped one of my friends make a hanger for his huge Ohio hash plate. I guestimate it weights 15 pounds. I learned this technique from Harry Pristis, and only slightly modified it from what he posted. I used two steel rods from Lowes, and two turnbuckles from Home Depot. The materials cost was about $10. I used a wire bending jig to create two W-shaped "hangers" as shown. This jig was one like this; costs about $5. I bent the end of the hangers over to hook onto the plate. I used two turnbuckles to attach the rods together- and screwed them tight. I probably could have used wire, but wanted to be sure it would never fall.
  9. Interesting Looking Fish

    So this is my second fish post of the night. Just wanted to know what this guy was, and the time period it may have come from. Thank you!
  10. Harry Pristis pointed me to this method, so I thought I would show how it worked out. This only works with fossil that are fairly rectangular or square. A little deviation is okay, depending on what frame you choose. I used Nielsen sectional aluminum picture frames. https://www.nielsen-design.de/en-EN/products/frame-mouldings-aluminium/ They come in a wide variety of colors and styles. When I bought a frame, I told them the exact size of the slab, and they added a tiny bit when they cut it, so the slab would fit inside. So, check with the seller to see if you are ordering the exact size of the slab, or if you need to add a little length yourself so the frame sits inside. I recommend using a carpenters' square when measuring, it made it a lot easier. You need to make sure the frame you are ordering has enough overhang to cover up any potential gap between the slab and the frame. I chose the N95 frame which has about a 1/3 inch overhang. There are frames with an overhang closer to 1/2 inch if you have an irregular slab. You need to make sure the frame you get is deep enough for the thickness of the slab you get. The N95 frame is about 1" deep. Here is what the N95 frame looks like: There are steel angle brackets you use to screw the frame together; here is one of mine seen from the back: You add steel spring clips to press the slab against the front of the frame; I did not use glass: Now, you can use wire to hang the picture; I decided to use the nielsen security hanging system instead; this locks the picture against the wall. It can only be removed with a special tool. So, if someone bumps against it, it won't fall and shatter (or be stolen). They cost me about $4.25 for one set. HOWEVER, I will say removing them with the tool is really annoying, so if you use these I hope you won't need to take them off for a long time. Here are the brackets for my small one installed; it has one hanger up top, and the "lock" below. On my larger slab, I used two hanging brackets up top. So, here are how they look finished: I know we aren't supposed to post retailer's names here; if you want to know where I ordered the frames, send me a PM. These can be ordered at a lot of places online though. The prices for the small frame and all associated hardware, including the locking hangers was $15.30. The price for the larger frame and all associated hardware including locking hangers was $20.46. Shipping was $11.65. So far, I am very pleased with this method, and would like to use it again. Thanks to Harry for the tip!
  11. Help with a Crinoid slab

    I just got this slab in the mail today. Overall I am SUPER thrilled with it. It had been advertised as a pair of Crinoids on a slab, but it looks to me like there is a possible third Crinoid that might be even bigger than the other two still lurking in the matrix. There might even be a forth one, and it looks like some possible trilobites scattered throughout. I am newer to prep work (and fossils for that matter), but this looks like it has the makings of a really neat plate. My questions would be if you think I am right in my assessment of the plate, and also what steps for prep work. I am getting into it more, but I am thinking of trying to find an expert to take care of this one since I really don't want to ruin it, it is really nice as is. As a side note, on one of the prepped Crinoids there is a trilobite wrapped up in the stems! I don't think it needs more prep, but still thought I would mention it just since it is neat!
  12. Which Fish?

    This was given to me as a gift many years ago. Its the only fossil I have that I didn't collect myself. I know nothing about it its age or where it was found, or if it is possibly a fake. If it is to stay in my collection, I want to have a good ID and if possible a fairly accurate location and strata.
  13. NSR160530 192

    From the album North Sulphur River 160529

    An iron-replaced hash of bivalve and other broken shells.

  14. Any ideas what animal? Appears to be bone. Found on beach on Manasota Key FL. Measures 3" wide by a tad over 2.5 wide, about 1/2" thick. Appears to have part of edge broken off in one area but then worn rounded as other edges. Also note 2 marks (indentions) Could these be bite marks? Could this be from a vertebra? Learning so much on TFF and enjoying so much!
