  1. Fossil catastrophe

    I have posted many times pictures of my big Phareodus testis fossil. Well, it fell and broke today. Fortunately, I have all the pieces, and I am going to put it back together as soon as I get some of the right glue. This is a disaster. My best and biggest fossil broke. I am not too upset, because there is hope to fix it, by the way. As soon as it is fixed, I am going to put it in a sturdy frame so this does not happen again. Ill post pictures when it is fixed. Jared
  2. Hi there I recently purchased a Albertasaurus tooth. A portion is in a matrix and there are some broken off pieces. This would be my first attempt a putting a fossil back together. If you could provide any input on 1. if it would devalue it by doing it, 2. how I should do it, 3. and what tools or glue or putty I should use. If you could dumb down the language for me that would be appreciated, like I said this is my first time!
  3. Broken Glossopteris

    So I have recently seen a few Glossopteris of interest and have bought a few to add to the collection. This one arrived in the mail in pieces Am quite disappointed as it was a good size (24 x 15 cm) at a very reasonable price. The seller has given me a full refund and has said I can keep the item. (Must say that after seeing a number of "red flag" items on their website, I will never touch this company again)....anyhow. Is this worth repairing? If so, how would I go about it?
  4. Crazy glue or epoxy?

    Hi all. I was hoping to find a pinned set of notes on when and how to use the various glues available for strengthening weak pieces, or repairing fractured ones; but there doesn't seem to be one. Can anyone point out a great thread, or chime in here on what you use and why you choose it in a given situation? Thanks.
  5. Hi there I recently purchased a cave bear paw and arm. It unfortunately cracked almost clean thru along a pin at the end of the humerus and a few piece broke off the head of the humerus. The seller said to use super glue for the repair. I am a total amateur. Is this the best thing to use? Any recommendations on how repair or what to use. If you recommend something other that super glue please let me know if it's something I can buy online Thanks!
  6. Which of these two would you pick? Both say some repair and restoration and I can see the repaired cracks and assuming the darker areas are the restored areas. I have no idea and the dark brown is on both unless it’s part of the glue and wondered if it would come off.
  7. Removable Filler Putty

    I have been working on a larger prep project and i have been brainstorming ideas for how to deal with a crack that formed when prepping. The crack is between two halves of bone and they are not as close together as they could be. I have considered re breaking the two halves and then re gluing but after thinking on it awhile, im not sure i will be able to get the two halves any closer together than they already are. So for display im thinking i will fill the crack with some sort of putty that conceals this crack. My concern is just that later on, if this piece ends up in a museum collection and someone wanted to reverse this and join the two halves in tighter alignment, they would be able to remove this putty or whatever was used without to much trouble. I have used a number of different putty's but im not aware of any removable ones. Im looking for any suggestions for removable putty's or alternate crack filling solutions. Thanks, Nick
  8. I present this here large asaphus trilobite, besides being repaired how much if composited/fake is this trilobite?
  9. Mammoth Repair

    I picked up this mammoth humerus from the Brown County Museum of History a couple weeks ago and have begun the repair. Apparently, someone tried to move it and it must have gotten dropped. I don't have the story on the damage, only the request for repair. Nobody's admittin' nuthin'! It came to me in 3 boxes (never a good thing for a single bone). This bone has an unknown provinance but has been at the museum for decades. Judging by the state of the plaster restoration, I would say this was done sometime in the 1960' or 70's. I soaked the exposed bone in stabilizer and applied a liberal mount of clear, non-expanding, Gorilla Glue to the joints and strapped the whole thing together for a couple of days. My lab is still covered in Green river fish so, while the wife was away from the house, the bone got moved to the dining room table. to her credit, she didn't say a word about it when she got home! I think she's been around me long enough to expect random dead things showing up in her house. This was when I discovered that I am completely out of white Apoxie Sculpt for the crack filling. Thankfully, I have to paint the repairs anyway so, they will get dark brown epoxy. I don't have a picture of the epoxied cracks yet but they are done and I've used about a gallon of cyannoacrylate on the plaster because upon closer inspection, the whole thing was covered in hairline cracks and just waiting to fall apart. I don't want to do a full restoration on this thing so I made the decision to save what is there.
  10. Repairing a broken meg tooth

    Hello, I bought this megalodon tooth some time ago. I let it fall on the gound recently and now it is broken. I managed to find most of the missing pieces and started to put some glue. Is it possible to restore it ? Best regards,
  11. Hello everyone, I recently received this large 14inch ammonite and the shipper had no care in the world to put even an ounce of protection thus this is the result I'm not experienced with much prep and not confident superglue would cut it so what would you all recommend to help repair this specimen as well as clean off some of the dirt/dust layer coating alot of it?
  12. Hello I'm a newbie fossil collector (and newly active member) who happens to several interesting fossils for a decent price from our favorite auctions sites 1st is are Knightia. The seller claims that they are not restored or enhanced 2nd set are 4 Spinosaurus teeth. The seller claims that cracks have been repaired, but no restoration or composition has been made (Pictures 2-9 of teeth in pairs) 3rd is a Lycoptera which the seller claims is not restored or enhanced 4th are plates of Elrathia Trilobites from Wheeler Formation 5th are Fossil Ferns from Llewellyn Formation 6th is a Hyracodon jaw fragment I would like to ask if the sellers' description of the items are accurate and/or if they are restored, enhanced or composites. Cheers!
  13. Hey guys. So my friend recently gave me this awesome fossil canine tooth from China. Unfortunately the tooth has been very badly glued back in 2 different places after it was broken. I would like if possible to know how to remove glue, superglue in this case so I can reglue it properly. I would not like to risk the tooth being irreversibly damaged... Do you guys know how and if I could do that? Thanks for any imput. Kind regards, Thomas
  14. Hi All, I came across this Merycoidodon Oreodont Skull and was curious as to the actual level of restoration that's been done. As far as I can tell the grey putty filling is where work has been done to stabilize the skull, but bones haven't been recreated. Am I missing anything else? Thanks! -Barret
  15. Hey there, im hoping some of the clever folks here might be able to offer some advice on a prep im working on. Im currently prepping a large 150 - 200 pound block. In the initial prep, a part of the block cracked and opened up a small crevice. This crevice did not beak completely into two pieces, it was still held together by the un removed matrix surrounding the fossil. At the time, i didn't want this to slowly shake into a bigger crack or lose pieces due to the vibration of the air tools. There was/is a lot more prep to do and between prep and flipping over a large block i was worried about loosing pieces. So i filled this gap with super glue with the idea that i could reverse this later on and join the two pieces together much tighter so the crack would disappear or be less noticeable. As the prep continues, im getting closer to the time when im going to have to re glue the pieces. The problem is that a lot of small pieces of the fossil are glued back on around the area of the break. So i need to figure a way to dissolve the glue at the break but not in the area around the break. Normally i would place the entire fossil in a tub of acetone to dissolve the glue from the joint and then glue the two pieces back together. But since there are a lot of small, non descript pieces close to the break, im reluctant to do this. I already tried poring acetone over the break to try to separate the two pieces but this didnt work. This would all be easier if the fossil was not so large, heavy and hard to move. I may end up having to soak the whole thing in acetone to dissolve this joint but i want to avoid this if possible. Does anyone have any suggestions for alternate ways to remedy this problem? Hard to photograph this fossil so here is a basic drawing of the problem. Nick
  16. Hello all. I recently received a fossil branch in delicate shale. It wasn't packaged well and arrived broken. It is a shame. I want to know what the best way is to repair it and hide the cracks. The first picture is what it looked like before it was sent to me. Thank you! ps: if anyone knows what it is an ID would be appreciated as well, but my primary concern is the best way to repair it.
  17. Moroccan “Croc” Repair

    I got a call last week to pick up a croc skull for repair. I excitedly went to get said skull only to find a rather poorly done fake for me to repair. I said, “you know this is fake right?” The response was “uh, yah. Go ahead and fix it.” So, I have gone from fossil preparation to “art” restoration today. This is what I had to work with. Seems easy enough right? Wrong! The hard part about fixing a fake is understanding how the fake was built in the first place. This is made of random bone fragments cemented into a “matrix” with random croc teeth cemented in place. They didn’t even try to make it look real, clean up the cement, or put teeth in the right place. So, I had to figure out where these things are “supposed to go”. After the repairs were done, I scraped off some of the “matrix” and made a paste with glue to fill the cracks...
  18. I just returned from a collecting trip and to my dismay i realized that i am missing a piece of a fossil bone i collected.. The bones at this site are in concretions and are not always visible on the outside so a lot of the time they have to be broken to know for sure what is inside. I thought i had a fairly clean break but when i got home and re assembled the pieces, it seems that one section of the bone is missing in the center. I have delt with small problems similar to this before by filling the missing space with Durham's putty and sculpting it on the edges. With this fossil, an entire section of bone is missing. So i will want to reassemble the rock and fill the section before i start in of prepping it so i know exactly how wide the space is. My concern is that something like Durham's wont be strong enough to support the full strength of the bone during and after preparation. Can anyone suggest a similar sculpt-able putty that would not shrink and dry incredibly hard? Since the concretion is in pieces its hard to photograph in a way that conveys what i mean so i drew a picture of the problem. Nick
  19. Hello everyone, I purchased a Keichousaurus from our favorite auction site. It was a reputable seller and using a black light and closer inspection it's real. Plus I have the added bonus of it having been dropped and split through as it was only packed with newspaper and not market fragile, then played footy with by australia postal service... so, yeh.. its' real but it's broken. The top left has crumbled and is discolored. and it has a crack through the tail. Can anyone advise me how to adequately repair this? I have been promised a replacement specimen which will be sent soon, But I would like to salvage what I can. Thanks in advance.
  20. It seems that all my equipment is giving me problems lately. The newest aggravation is a hose problem that I'm hoping someone can help me with. I'm getting no air flow from the moisture trap to the pen. I can unscrew the release screw on the trap and it comes out fine, but it won't travel through the hose. I've tried reversing the flow as well as blowing it out at high pressure, but neither works. I've tried pinching the hose to look for blockage, but I can't seem to locate one. This part of the apparatus is not meant for disassembly, so I can't simply disconnect the hose from the trap to see what's going on. Is this fixable, or do I have to locate a replacement part?
  21. Hi All. Opinions please. I found this item on everyone’s fave auction site. 14cm Seems a side on view? Aside from the obvious repair, any red flags?
  22. Hi all, I recently purchased this Keichousaurus specimen off an online seller (not online) and wondered if it was genuine or not... the seller stated that there had been repair to the matrix (don’t know if that shows up in the attached images:|) The seller also said there was no repairs, painting, carving etc and that the actual fossil was 100% genuine. Inspecting it with a loupe I could see the bone matter is raised from the matrix (slightly) and that there may be teeth present on the skull, but I don’t know if they’re painted on, as that is sometimes the case. Anyway I thought I’d come here to get it checked out as I’m not very experienced with fossils and fakes yet. Any opinions would be greatly appreciated Jai.
  23. 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
  24. Elasmosaurus Tooth Repair

    I received an awesome set of Moroccan matrices from @caldigger (thanks again!) that included a cracked elasmosaurus tooth. I didn't consolidate the tooth before prepping, as the matrix surrounding the tooth was far harder than the rest of the block, leading me to believe it had been sufficiently consolidated. It split at the crack whole handling it before prep work even begun, so I continued with the rest of the tooth and got the rest out pretty cleanly. The fossil isn't valuable, so I'm not too worried about perfection! Its all part of the learning experience for me. My question is about the correct order to go about repairing this tooth. When you line up the pieces, there is still a small hole from a missing section, and I suppose filling it with the matrix and then adding a layer of Paraloid dilute would be the best way to go? So here is my (tentative) plan of repair: Consolidate the pieces in the dilute Super glue the bits back together as cleanly as possible Fill in the cracks with wet matrix (?) Let it dry, then gently coat again with the dilute solution Would exposing it to the dilute twice be overkill? And I know acetone tends to dissolve super glue, but I assume the glue would hold if it's inside the tooth and the second coat of Paraloid goes on just the outer layer after it has all dried? Hopefully I explained my intentions well, and I'm looking for ideas as to what would be the best order to attempt these steps in or otherwise a preferable method (if there is one) of repair!
  25. I saw this item for sale which is of interest. Dercetis sp from Lebanon - Cretaceous. Contacted the seller who informed me that the crack is a repair, not a composite. Thoughts?
