    Kane's Bug Preps

    UPDATE: Consolidated all my loose preparation threads into one topic. Four hours so far into this big bug, and maybe another two to go. Found at Penn Dixie this past weekend, the visible area measures 6 cm. With the pygidium, it likely measured about 8+ cm. Judging by its size and pustular sculpture, this was likely a long-lived specimen prior to burial. This is how it looked fresh in the field:
  2. Some weeks ago I went "digging" to a huge fair in France. You never know what you´ll find, so I was happy to get a biiiiiig Stylemis from the badlands. Approx. 45 cm long, its the second biggest we ever had. But, the conditon... eroded, but the turtle-shell is great. So, we decided to buy and prepare. Takes longer than expected, just working on it and hope to finish before Christmas... Lets start with some pics, I add new ones when I went on with preparation..., enjoy first pic was done at the fair, first steps are: cleaning, cleaning, cleaning... and remount / glue
  3. Hi Fossils Preparation Fans, Last week I received 1900kg of unprepared dinosaur bones in plaster jackets. Now my neigborhood thinks I lost my mind and I received a lot of eye-rolling from my wife. However, my two sons (7y and 2.5y old dino fans) and myself think it was an excellent idea to acquire the material. The fossils have been collected in the upper layers of the Morisson Formation. Location: Moffat County, Colorado As always when buying unprepared dinosaur bones you do not really know what you get. However, it seems that most material is Apatosaurus (
  4. After a loooong long time I've got a new piece to prepare! I recently recieve this beautiful Hyaenodon canine from Saint hyppolite de Caton (an upper Eocene locality). Many of you would prefer to leve the tooth in the matrix but I'm just to curious to extract it a see how is preserved on the other side but also because this is rock is super rich of fossils and I want to see if I can find anything else.
  5. Good Morning. I am looking for a quiet compressor that allows me to use in a residential area. Preferably I would like to visit a shop. Does any one have any advice. I have the equipment to go with it. Thanks, Sue
  6. The first (and only- for now) Oreodont skull I prepped was in remarkably good condition and required virtually no reconstruction, just a thorough and careful cleaning + a little stabilizing. Afterwards I was looking for a good way to display this little skull in a manner where it wouldn't just be sitting on a flat surface. I'm not great at bending metal to create an elevated cradle so I came up with this: I laid a sheet of plastic wrap on the underside of the skull and gently pressed Apoxie sculpt on top of the plastic so it molded to the contours of the skull. I then pressed a met

    What should I prepare?

    Hello again, I have recently ordered some bits from ZoicPaleotech for my dremel 290 engraver. I've had quite a lot of practice with the normal bit the dremel comes with ( as I am waiting for the proper bits to arrive). I would love to buy some unprepared fossils from the forum in the future. I've practiced on some soft shale matrix containing trilobites, and I found it quite easy, and very satisfying because the rock pops off the fossil easily. Do you guys have any suggestions on fossils to prepare in order to help me grow more accustomed to preparation?
  8. Hi all! Thought I would start documenting my trilobite preps. Here is #1, a Calymene breviceps from the Waldron shale, Indiana, and my first real prep. This is about 15 hours using hand tools primarily and a dremel for clearing some of the original matrix. My fingertips are sore, but lots of fun was had! Very exciting to see this feller reemerge after 400,000,000 years! Now to track down some other unprepared trilobites…. Trickier part of the operation…
  9. Alright fossil preppers, show us what you're working on! I've been working on prepping this Priscacara for about 6 months on and off with a pin vice.
  10. Hi! I'm looking for advice. I found this fossil yesterday and like so many others I find it's on an unstable piece and has a major crack through it. I'd hate to coat it with anything as I prefer to keep things natural. Yet I'm also worried that it might just fall apart on its own or from handling. What's my best course of action? Any advice/help is appreciated.

    Preparing Crinoids

    Hello fellow fossil fanatics, I recently found some great crinoid fossils, and I was wondering if any of you had recommendations regarding how they would be best prepared. Both fossils are in two pieces, and I bought Krazy glue today to fuse the pieces together. Since I have never done this before, is there any particular technique which allows for the best bonding? Should I separate the pieces, apply the glue, then reattach? Or should I try to have the glue seep into the seam between the pieces without separating them? The rocks both seem to be very full of
  12. I've been recently looking into working with b72 for preserving and strengthening some of the pyrite and coal fossils I have. At the moment, I have a few questions regarding this topic: 1) For DFW folk, do you recommend any stores that sell b72 in the DFW area? For others, do you recommend any reputable online stores that ship it? 2) Should I store acetone in the original container I purchased it in? What is the safest part of the house to keep it? 3) What are any general tips/tricks you wish you knew before you started using b72? Feel free to answer as few of
  13. I'm starting to get into mechanical prep seeing as with the quarantine I have extra time on my hand. My equipment arrived before my projects did so I've been practicing on this invert I had on hand. I believe this is a gastropod? Or is it a bivalve? I can never keep them straight in my head. Anyways, I forgot to take a before picture so I apologize for this awful photo as it was the only one I had: And this is it currently: Obviously not done yet, needs some more work and then some serious clean up to make it look nice but I'm thinking to put it aside for a

    Hidden Fossil

    Hi, I found this beautiful little asterophyllites yesterday and noticed that there seems to be some rock covering part of the fossil. I'd like to be able to remove the rock and expose the fossil. It's very solid and too thin for any of my chisels. Would an air-abrasive pen or dental equipment work? Perhaps professional help would be appropriate.
  15. Hello, This might be a simple/straightforward question, but I'm still curious to know how you guys deal with all the rubble created from fossil preparation.

    oviraptor egg prep?

    Hello fossil friends I will be acquiring a clutch described as Elongatoolithidae that came from a collection out of China in the 80s. Short of sending the piece out or acquiring a $1000+ air scribe setup, what can be done as far as getting rid of some of the calcite on top of the eggshell, or better expose the underlying details? I possess a dremel with many different attachments and access to the hardware store for more supplies. I've read that the matrix these are found in can be very hydrophilic so want to avoid turning it to mush. Thanks for any comments
  17. Hi everyone, Im new to this forum but have stumbled across it while trying to find information about psittacosaurus, I have a quite large complete (I think) specimen, over 3.5 feet long. The bones are prepared but not mounted. Does anyone know of anyone in England that can prepare these to being mounted? Looking forward to speaking with fellow collectors out there kind regards
  18. Hello everyone, I am a new member and i do not understand much about fossil. Although i am very pationate about them. I found this fossil myself and i would like to remove the matrix attached to the fossil. I tried vinegar and a tooth brush. It kinda worked on the top of the fossil where you can see the tiniest spirals. That method cosumed about 2 days of work and only uncovered that tiny piece of the fossil. I am also concerned that the acid frrom the vinegarr will partially destrroy the fossil. What is the best way to do this? Best Regards, Bruno
  19. Hello, I have a question regarding best preparation techniques for Eocene concretions from Sheppey. They look like this: I'm not doing the preparation myself - I'm asking to help the guy who is supposed to prepare them, as it's a new material for him and he doesn't want to ruin the fossils. I will appreciate your expert advice Kasia
  20. I'm prepping fossils in Oolitic limestone, which is new for me. This fossil is small and delicate, and appears to be a tooth. Should I use hand tools, or what I was thinking was cotton bud, vinegar and a lot of patience? I'm concerned the vinegar would attack the tooth. The white patches are where I scraped the matrix with hand tools, but I wasn't confident this was the best method.

    UAE Crab

    Hello. Do you guys think I can prep this crab from Al Ain (part of the United Arab Emirates)? It looks pretty beaten up, but I am hoping the ventral side might still be there. I have tried preparing urchins in this matrix with a very diluted water-vinegar solution. Do you think this could work for the crab as well?
  22. Hello all, With the start of this month I have gotten back to doing some fossil prep. I am still very much learning but I am happy with how this one turned out. It's a Callianopsis clalamenis nodule from the Pysht formation of Washington State which I found this past January that preserves two sets of feeding and defensive claws as well as some disarticulated shell material. This prep was fun and I am excited to try another shrimp, they are a welcome break from working with very hard pyrite nodules from Yorkshire. Before prep: After about half an hour

    Trilobite Prep Question

    Hello Forum, I've been working on some beginner Trilobites I've been able to buy from a local Rock Store. Most are not in a good state of preservation but are fun to work on and learn. The bug below has a waxy coating on it and I'm wondering if someone can tell me what that is, and also the best way to clean it off. I scribed down to the shell with an air tool, and now I'm just using a pin vise to scrap away as much as I can. Is this the best approach?
  24. Hi all, I am finally getting ready to proceed with stabilizing the specimens I found in this trip: They are basically big sandstone steinkerns, now fully dry. They were found in ferrous sandstone concretions surrounded by sand. The matrix is soft , pieces can be broken off with fingers. I was advised to brush ammos with a PVA solution, but then I thought what if I use Paraloid instead? So the questions are as follows: 0. Is it worth it? 1. If so, what solution should I use? 2%? 5% or more? 2. How much will be required? (the biggest ammo is about 40

    Small Ichthyosaurus

    Hi to everyone. I'm preparing a new fossil which comes from Germany in the Cretaceous, these are the information that i have. Now, I have seen that it's quite difficult both to recognize the bones and to eliminate the matrix but the work is going. Have you some advice for this type of fossil? And, i don't want to be wrong, but i see two different bones: a black one and a brown one. Are them two different animal or not? For the type of preparation I'm doing is a mechanic type.
