  1. Hey everyone I am preparing a rib from the Hell Creek formation it isn't in the greatest of shape and I still had a long way to go but wanted to start thinking about maybe trying restoration for the first time and wondering what you guys recommend. Here is the startand here is where I'm at right nowwith the right side there will need to be some fill to the missing bone. My question is though with the degree of curve on the right end do you think I'm close to the head and should try reconstructing the head? I could be looking at the curve wrong too and just have the bottom of the rib, either way though is there any method you guys use in reconstruction to get the bone texture? Thanks for the help I'll continue updating this as I get further into prepping it.
  2. Hello! Sorry to add another keichousaurus to the forum but I was hoping to get some help. I've always wanted one of these but have never done it because I am worried it might be fake. So, if anyone could provide input, I would be super grateful. I looked at the things to look for both in reals and fakes and nothing really stood out to me about either being real or fake. I am okay with slight restoration but would like it to be as authentic as possible of course. I cropped the picture to respect the identity of the collector and dealer but some of you may have seen this, haha. Thanks in advance forum!
  3. I've often wondered what some of the fossil shark teeth in my collection would look like if they didn't have root damage, missing cusplets, etc. Many of these imperfect fossils are somewhat rarer and/or otherwise favorites of mine, so I've been hesitant to permanently alter them through restoration. Recently, I decided to go ahead and restore several of these teeth--but wanted to do so in a way that wouldn't be permanent. The technique I've adopted is to first paint the broken surfaces of the teeth that I want to restore with a couple of coats of liquid latex. Once the latex is dry, I then shape and build restored roots, cusplets, etc. out of epoxy putty on top of the intervening latex layer. The putty sticks well to the latex and can be shaped to match the tooth without directly touching or bonding with the fossil. In most cases, when the putty is dry, the restored pieces have been easy to detach with a simple tug, as the putty doesn't permanently bond to the latex (the latex layer itself is also then easily removable/peelable from the fossil). In a couple of cases, I have unfortunately caused a bit of damage to teeth in the process of removing the restored pieces. Once, because I inadvertently pushed the putty into an indentation in the root of the tooth and as a result it couldn't be cleanly pulled off/out. Another time, the tooth I was working on was more fragile than I realized and the force of pulling the putty off caused a fracture. Luckily, the damage wasn't too extensive in either case, and I've (hopefully) learned to be more careful. I had never attempted to restore teeth before but I found some very some helpful tips for doing so on TFF here and here. A few additional notes on materials and methods: The "white" (it's definitely more of a gray) epoxy putty I've been using is Apoxie Sculpt, which I ordered from an art supply store. I ordered the liquid latex online as well. For root surface texture, I've also used the liquid latex to create several small surface molds from different fossil teeth, which can be pressed into the epoxy putty before it hardens (as recommended in one of the TFF posts linked to above). I use an X-Acto knife for texture and shaping as well. I use fine sandpaper of varying grits, from 400 to 2000, to smooth the "enamel" portions of the restorations. I use acrylic paint for the colors--sienna, umber, tan, black, white, red, blue, yellow--and finish things off with a clear matte or clear gloss acrylic glaze to improve durability (the gloss glaze is for "enamel"). I use small amounts of non-permanent Museum Wax (ordered online) to attach the final restored pieces to the original fossils. Below are several of the results (the original teeth and the detached restored parts are on the left and the final teeth with their restored parts "attached" are on the right of these images). Otodus obliquus tooth from the Eocene of the Isle of Sheppey, Kent, UK -- restorations to the root and a missing cusplet: Cretodus sp. tooth from the Cretaceous of Texas, USA -- restoration to the cusp (I did a better job of color matching on the lingual than the labial side of this one): Cretodus sp. tooth from the Cretaceous of Texas, USA -- restoration to the root and a missing cusplet: Dwardius siversonii tooth from the Cretaceous of Stary Oskol, Russia -- restoration to the root: Otodus aksuaticus tooth from the Eocene of Maryland, USA -- restoration to the root and a missing cusplet: "Hubbell" Otodus megalodon tooth from the Mio-Pliocene of West Java, Indonesia -- restoration to the root and a small part of the cusp: Carcharodon carcharias tooth from the Mio-Pliocene of Florida, USA -- restoration to the tooth and a small part of the cusp:
  4. Hello, How much of this Russian ammonite seems natural and original? Any compositing or restoration (aside from the obviously poorly-restored inner whorl section)? To me it looks good aside from the inner whorl, but sometimes they restore these super well so it can be hard to tell. @Kanopus
  5. Hi all! I made a post previously about contemplating buying an anomalocaridid appendage, but considering your feedback, ultimately decided against it. I'd been saving up for a fossil that I was really excited about, and ultimately decided to take the plunge on a gorgeous Eurypterus Remipes from a very kind seller. I spoke with the seller of this Eurypterid prior to making the purchase, and he had mentioned that a small portion of the dorsal postabdomen was restored. I saw another portion of the prosoma and attached appendages that I thought might be restored as well, asked about it, and the seller was transparent about being unsure of whether it was or not. I think it is, but I was wondering if you all would have any insight. Beyond those two sections is there any reason to think that the rest of the fossil is anything other than how it was found? It look otherwise legitimate? I've attached plenty of pictures! Thanks!

    Meg Restoration

    I was asked to do a restoration on a nice meg tooth recently collected by a client. When I received it, it smelled like catfish bait. It spent a week submerged in isopropyl alcohol and came out smelling fresh! No stinky tooth. After a few days to ensure all the alcohol had evaporated, I got to work rebuilding the missing bit of root and enamel with Apoxie sculpt. I got the rough shape and let it sit for a couple hours. Right at the end of its working time, I did the final shaping, texturing, and cut in the serrations on the “enamel”. Then it was a marathon of painting to try to mimic the mottled coloration of the tooth. I never try for an exact match for 2 reasons. 1 it’s impossible. 2 if this ever makes its way into a museum collection, the restoration should be obvious to a trained professional. I think this one toes that line pretty well.

    Suchomimus Foot Claw?

    Looking at purchasing this claw and it’s labeled as a suchomimus foot claw. There is restoration but was told only the tip has been restored. Is there more resto on this claw or any other red flags from what you can see. Any info on this claw will be appreciated!
  8. I want these to stay pristine as possible. I’ve seen modern teeth age badly. I don’t want this. Please help! special teeth
  9. Hi guys. A little while ago, I broke my precious Spinosaurus claw... I can't stand up from the shock... I want to fix it, how can I fix it? please tell me. Thanks in advance.

    First restoration attempt

    Hey everyone. I've been blown away by some of the shark tooth restoration work out there so I wanted to learn this skill for myself. I practiced on a real beat up tooth I found. It was probably too challenging of a tooth to restore on my first attempt but I figured it would be a good opportunity to practice restoring the root as well as enamel. The sculpting material hasn't completely cured yet but when it does I will be smoothing it out and then painting it. The enamel areas definitely need smoothing. It's far from perfect but I just figured I'd share this first attempt. Below are is a photo of the tooth how it looked before, some progress pics, and how it currently looks. I'm going to keep practicing. If anyone has any tips or tricks that would be awesome!
  11. @caldigger post on finding two pieces of the same tooth reminded me of the tooth I found in New Zealand many years ago. The site is closed now, so I don’t think there is a chance of finding the root. But is there anyone on here that could accept this challenge? I’ll pay of course! Tooth overlying picture of complete tooth of same size and position showing the missing root. The slightly trickier bit is on the back where the root/enamel transition is partially missing. Scale bar = 2 inches total. A few more images of the tooth;
  12. Was inquiring to purchasing this tooth but want to make sure this tooth looks 100% natural with no repair and nothing restored on it as claimed by the seller, thanks for the help!
  13. Hello, I know that this skull was already shown a few years ago on the forum and it had attracted rather negative comments but I don't remember it very well. I bought it 3-4 years ago, and I would like to know what you think about it. Of course I think there is some restoration (where? is it that bad?) I remember one member asking why one could buy such bad skulls while showing a Psittacosaurus skeleton of extraordinary beauty and purity, but very few people can actually buy this. So I would just like to have your opinion on the general quality of this skull, is it authentic? what is interesting about it? any horrible things visible? The detail I find interesting is that some teeth are visible. I imagine that the fact that the skull is deformed/crushed comes from the pressure of the rocks? I had asked a friend to try to remove the remains of gangues especially in the orifices but he told me that it is better to leave it like that because when he started, all the small bones were crumbling, it is too fragile to do that. Thank you in advance for your illuminating comments which I always read with great profit and pleasure,

    Basilosaurus jaw?

    Is it just me, or does this look like there’s a good chance that it’s either totally separate pieces with significant restoration connecting it, or even just quite a bit of fake areas? I feel like especially from the right side, it appears to be a huge amount of just matrix visible, and even on the left side a good deal of area that’s just matrix. I know that matrix isn’t unusual on pieces, and I wouldn’t mind small amounts of restoration/places of matrix filing in missing areas, but not large portions of something.
  15. Hi everyone! I just got a 20" mosasaur (Prognathodon?) jaw piece in the mail, and unfortunately it was split into 3 pieces. Fortunately, the breaks are fairly clean, with a few small fragments broken off, and the pieces fit right back together. If anyone has experience with this sort of thing, what kind of glue do you think will work the best, and what application method would you use?
  16. Hi Guys, On my adventures in Banff a few weeks ago I found a sinohydrosaur fossil for sale which I fell in love with. Admittedly I was concerned on transporting it back to Australia considering the almost 18 hour journey and not being allowed as carry on. Even with all the cushioning I could offer the specimen it ended up cracked in half. Thankfully (maybe) it did so along the tail side and the break appears to be somewhat clean. Having never had to fix something of this nature and not knowing the rock it's embedded in and this being my first fossil I would love any insight into how I could restore this. Also I'm not going to like the answer but what % of value do you think I have lost due to the damage? Thanks in advance!! - oedinum (read as sad)
  17. Hello There's an unrestored phareodus fish fossil I'm thinking about purchasing. How difficult is it to restore these and what do they use to highlight them? I'm a very patient guy and already have the tools needed. Just not sure to to go about the highlight process. Any help would be appreciated.
  18. I saw this tooth for sale and it looks like it has restoration on the yellow batches, however seller strongly believes there are no repairs nor restorations, want opinions on whether you think it has restoration.
  19. Hello, I was wondering if these chinese Keichosaurus looked real? How much reconstruction/restoration if any, and how is their condition? Both slabs are about 9 inches long. First looks ok to me, second's body looks a bit weird. Thank you! 1. 2.

    Any repair or restoration?

    Hello! I was just wondering if this mosasaur tooth looks like it had any repair or restoration done to it. The tip is darker and in some angles it maybe looks repaired. But then it also maybe just looks like different degrees of enamel wear. Thanks for your help! Kevin
  21. 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.
  22. I just wanted to share this, thought it might be of interest and there's definitely room for improvement and tips! This was the first fossil mammoth tusk I restored and prepared a few years ago- a juvenile mammoth tusk that was split laterally almost perfectly down the middle. It was sourced from central Alaska, though not sure if it was discovered in a mining operation or if it was exposed on a river bank as so many are. The first step was to submerge and soak the entire tusk in a PVA solution, followed by Apoxie sculpt and banding to merge the two broken pieces and restore some of the tip. I haven't ever done this before so I used the grey Apoxie, in retrospect maybe the white color would have been easier for later coloring? Maybe mixing color in the Apoxie pre-hardening? After banding and curing, the two pieces held together and it was time to sand sand sand down to I think 2000gr. Lastly, I colored the Apoxie fill with various wood stain colors, however I wasn't a huge fan of that- does anyone have any recommendations on how to do that better? I've never been a painter and know nothing about what to use or color matching, but would love some info! I've done other projects and thought about taking on restoration projects where this knowledge would be really helpful but admittedly I'm really inexperienced with coloring any sort of anything. I've seen people reconstruct 1/3 of a cave bear skull and it's like you'd never know unless you were really looking for it. I have no idea how they do that! I'm sure that takes some serious artistic talent that I don't posses, but any tips for this would be appreciated. Originally I built a stand out of bent/polished brass and a block of wood I got from a trophy store that is somehow still in business in this little Alaska town. A couple years after I made the original stand I decided to make a new stand out of a small petrified wood slab/slice. I really like the look of it better (though I'm not crazy about the brass anymore), but I had a really hard time drilling the holes in the slab- I broke a few bits before I bought some stone/tile bits, and even those weren't great! I was only able to drill the holes just barely deep enough to hold the brass wire. Any tips on drilling petrified wood?? I have a few other small things and potentially a few larger items that would look killer on a similar stand. I've done a few tusks since this one, none of them with such significant damage, though none are complete tusks I think I'll post another one of the interesting ones that has amazing vivianite and what I think are actual cobalt crystals in the internal cavity. The restoration done on this tusk is only for me, I have no plans on selling this so in looking for reconstruction/restoration tips & tricks, it's purely for my own collection and enjoyment- not to try and fool some unwitting buyer on our favorite auction website! To be honest, the preparation is the most fun for me! Enjoy! Nick
  23. I wanted to try my hand at fossil restoration and wanted not know what sort of material is used ? I believe some kind of epoxy putty is used ? Is there any particular kind that's used for smaller pieces that can be carved into shape ?
  24. Hello, Here is what I think is a nice lot of Hemipristis serra teeth from Florida, which are about 2~2.5cm size. However I have no experience with shark teeth or teeth in general so I was wondering if these seem real, if there seems to be any restoration/reconstruction? I think most of these have nice serrations, but how is the quality of enamel and root preservation? Thanks.
