  1. This looks to have some small spots of fill, but do any of you see something more? Also hard to tell if the horn was put into the left eye socket to make it look like a fascinating death fossil versus really found like that. thanks
  2. Hello everyone This tooth is one is like to buy if it's no repair, but it's a strange one. It looks as if it's supposed to have repair because the contours are off. But the enamel is really pretty. What say people here? Repairs?
  3. Hello all, I'm thinking of buying this carcharodontosaurus tooth, it's 78 mm long, but it looks a little restored in my unprofessional eyes. What do people here think?
  4. Ungluing help

    Hey, I was wondering if there was something I could use to unglue a tooth I’ve got. It broke during shipping and I glued it, but there’s a piece that I have that doesn’t fit where it should go. I don’t want to use acetone cause I know that can be harmful to fossils sometimes, and paleo debonder didn’t work great previous times I’ve tried using it. TIA
  5. Hi im and amateur collector and I'm not sure if the was the right section to post this under. I purchased this tusk a couple years ago. The seller said he's had it since the 1970s. Because of the large crack from top to bottom and the inside is quite powdery. Is there and thing I can do to preserve it? Its about 6.5 feet along the curve and 120lb so I get worried when I move it. Also I see that great patina on some tusks is that something that is added 5o make it shine or does it comes out of the ground like that? Any help would be appreciated!
  6. Specimen Repair?

    I was wondering if someone could advise me on whether or not I should repair this piece of Chiapas amber I recently acquired (it's a clean break with only a few small slivers missing; the specimen is exceptionally clear, and has no internal fractures); it was damaged during shipping, and I've been debating whether or not to repair it. What effect might a repair have on it's value, and would it be more acceptable to keep it as two separate pieces? I know the repair of fossil specimens is a generally acceptable practice, but I'm uncertain if this applies to amber (I'm guessing not, as amber considered more of a gem material). I occasionally repair amber damaged during the cleaning and lapidary process using epoxy resin, but I was reluctant to do this to such a decently-sized and costly specimen of Chiapas material without having sought further advice. Thank you!
  7. Edit: Wrong use of photos. Will update shortly! Hello! I've been eyeing this tooth for some time now - but before buying I could need a bit of help! The price is very reasonable for a tooth at 11,3 cm and overall the condition is good - which makes me a bit suspicious The market for fossils in the country I live in is very niche, which might explain the price, but I would like to hear the opinion from folks that have more knowledge than I do. Cheers! Anne
  8. Restoration

    I don't know if I am the only one that i hate restoration on the fossils. I love natural and original specimens. I prefer a tooth 80-90% complete from a tooth with restoration. Also, i prefer a B grade tooth with no repair, from a A grade repaired tooth. You?
  9. Big Ammonite Repair Adhesive

    Hello everyone! I managed to bring home this crazy guy, the problem is that it was so big it broke in pieces when extracting it. I've been using "Loctite Super Glue 3" (ethyl cyanoacrylate) for repairing my fossils until now and it worked pretty well. However, this one might be too heavy I'm afraid it wont be enough to keep the pieces together and it can be dangerous (since the whole fossil probably weights over 70 lbs). There are also some cracks I would like to fill, I heard a technique where you ground some matrix rock to dust and then use that powder to make a glue that has the exact same colour of the fossil, anyone knows about it?. To summarise: what is the best adhesive for heavy rocks? and, is there a way to fill the cracks so it won't look like it's broken? Thank you very much for your help. Here goes the picture of the fossil: Best regards,
  10. I've owned a sweet Keich that came from China via Germany in the mid-20th century. In our last move, it was broken. The photos attached show the main break point with missing vertebrae. The next photo shows the cross-section, just for the sake of proving authenticity (you can see how the matrix striae curve around the bone as well as the details of the spine in cross-section). As I was lucky enough to find the missing vertebrae I placed the pieces together in the next photo and held the pieces in place in the final photo to show how it should look when finally repaired. My question: What adhesive should I use to repair the matrix and is there something different I should use to glue the delicate piece with the vertebrae into place? Many thanks to all for any experience/advice.
  11. 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
  12. 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!
  13. 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?
  14. 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.
  15. 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!
  16. 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.
  17. 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
  18. I present this here large asaphus trilobite, besides being repaired how much if composited/fake is this trilobite?
  19. 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.
  20. 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,
  21. 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?
  22. 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!
  23. 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
  24. 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
  25. 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
