I found these Goniatites in the British coal measures. Would anyone like to prepare these for me in return for some fossils? I have many fossil types available. Please note, the inner whorls of these Goniatites are almost impossible to prep, so it would be best just to expose the outer whorl. I am not sure how well these will prep, but I have decided it’s worth a try to see how they will turn out. Thanks, Daniel

I found this partial coal measures fish in Scotland a couple of years ago. I don’t have enough experience to prepare this, so I was wondering if anyone would like to prepare it for me in return for one or more fossils? I have various fossil types available. Thanks, Daniel

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.

I had this weathered ammonite fossil I had found in a load of rocks dumped by the highway department under a bridge. It was weathered and not in fantastic shape but it had a lot of limestone on it still. Used some muriatic acid on it and let it soak in water and baking soda to neutralize it. Still not a great specimen, but it removed a lot of rock.

I'm posting a current project in the hopes that it actually makes me finish it. I have a tendency to start several projects and set them aside for years. This Lepticitis was found in Wyoming in the late 90's. The initial prep was done by someone else (unknown) before the specimen made it to my collection. I've spent the last 5-6 hours under a scope removing glue, I would have almost surmised it was dipped in penetrant. It appears to have some abrasion damage as well, see the dorsal view of the skull above the orbits. I also took the opportunity to clean out foramen and do other various cleaning with pins and needles to get it to the state it is in now. Wish I'd though to get a pic before I started. Thanks to @jpc, I have some excellent photos of another Leptictis to base reconstruction off of. I'll post some more photos as the work progresses.

So if you were going to get a blast cabinet setup, what would you get? I know that a person probably needs two different setups to do it the correct way. And I apologize ahead of time if this has already been discussed. I don’t want the cheap stuff. I want quality that’s going to last. So I’m prepared to have to step up to the plate money wise to make that happen. Thank you everyone ahead of time! Sincerely, J

Over the years, people have asked for some prep videos. My new blast box allows me to conveniently set my phone on the glass and run a time lapse video. Unfortunately, the files are too big to post directly so the links below will take you to my Instagram where you can watch the riveting videos. They are short since this is a test. Video Video

We’ll update this thread when we get working on it, but for now this is Skye (@Jesuslover340) and my latest prep project. Busted up Pleistocene pelvis. Not sure who it’s from yet. Pics are: 1. As found 2. Uncovering more 3. Showing size 4. Plastered 5. Breaking it free 6. Back at home. May seem ridiculous but this progression took 2 months to do. We were a bit slow/busy with life.

Hey everybody! I realized I never made a thread for my internship at the Field Museum in Chicago this summer. I interned as a fossil preparator under Akiko Shinya in the McDonald’s Fossil Preparation Laboratory (that’s the “fish bowl” lab on the second floor right next to Evolving Planet with the big window). There were some amazing things being prepared in the lab - an Antarctic Lystrosaurus, lots of Dicynodonts, Green River fish (some massive Phareodus), Sauropod femurs and ribs, a massive slab containing several sturgeon and paddlefish - but I’m not sure if I am allowed to post pictures of them, so for the sake of confidentiality I won’t just in case. This is the lab, and I always sat in the red chair, right up next to the window. One of my favorite parts of this internship was seeing all the little kids so excited about what we were doing in there and interacting with them. I was preparing a Priscacara serrata (specimen PF 16961) from the Green River formation of Wyoming, Eocene (~52 mya). All I used was a pin vise and an Amscope stereoscope. This fish also seemed to have slightly “exploded” from the pressure of fossilization as well, it’s jaw was crooked and head smashed, thought most fins seemed surprisingly well intact. The prep took 199.5 hours to complete, from May to August. I finished the prep on the final day of my internship, staying late after the museum had closed to the public and all the others in the lab had gone home. But it was far worth it, because "your name will forever be associated with this specimen." -Akiko Shinya I took a picture at the end of every day and I made a time lapse with it to see the growth! The link is at the bottom of the post. (I kept that floating scale in front of its mouth because I thought it was kind of funny that it looked like the fish was trying to eat it!) You can watch the time lapse Here

Rather than just post separate posts every time, I decided to condense everything into this thread. I don’t see many people posting Yorkshire finds on here, which is a shame as there are some brilliant specimens out here. Hope you all enjoy. Dan.

I have decided to do a live prep thread on a Dorset ammonite. The ammonite is roughly a foot across and is embedded in a big bit of matrix. I am exposing the ammonite using very basic tools, so fingers crossed I will post regular updates

Thought I would share before and after of an Oreodont skull I prepped out. It still needs some detail work on the teeth. I have reconstructed the 2 upper canines, my first time ever reconstructing any part of a fossil and havent decided if I want to reconstruct the rest of the skull. What do you guys think?

How does one determine if a nodule has fossils in it?
El_Hueso posted a topic in Questions & Answers
Howdy all, I tried searching for answers on the search bar, but couldn't find anything, so I'm hoping someone can help me out. I was going through the fossil prep section and noticed that many people seem to start off with a large nodule and remove all the matrix to reveal the fossil hidden inside. My question is, how does one (a seller, or person out on a fossil hunt) even determine that a big hunk of nodule has a fossil inside if there are no immediate visible indications of a fossil from the outside? Once again thanks. -

I have the 5 year old grandson for a couple days and he has been talking about Dr. Grant from Jurassic Park. He loves to watch that movie when playing with his LEGOs from Jurassic Park. So I decided to grab a couple Oligocene fossils (upper Oreodont skull and partial skeleton) from South Dakota that have some work that needed to be done on them, plus I knew he could not due too much damage if I watched him, so off to prepping we went. He kept asking for a paint brush because that is what Dr. Grant used in the movie. After a little bit of time with a dremel and an electric scribe and of course a paint brush- he had enough and so it was back to LEGOs- lol, at least I tried.

Well, I’m finally getting to dig into my truckload of fossils from my Wyoming trip with @RJB so it’s my turn to open up a prep thread. I spent a couple hours today poking around to find the perfect fish to start with. The 18” layer never disappoints. This good sized Diplomystus has 2 Knightia on top of it. I’m going to try to save both but I’m concerned that the right hand one is covering most of the Diplo’s skull. If that’s the case, the little guy will have to go! This is after about 90 minutes of scribe work.

Went to Virginia a few months ago and came home with a few Chesapectin nefrens encased in solid rock. This one was only exposed as a ring of shell material in a ball of clay, calcite, iron ,broken shell and who knows what else. Normally I prep things with soft brushes, dental picks, a water pick, and very gentle fingers. That wasn't cutting it this time and I had to get aggressive. I spent 3+ hours with a rotary tool and zero practice. It's no museum piece, but it's not horrible. I could simply collect the same species, from the same member of the same formation, at a much closer spot, where the matrix is much looser, but I gotta learn sometime. Suggestions for next time?

Looking for material to practice, like the u prep site but not as much of a gamble

I am hoping to get some advice on how to handle preservation prep on a recently found section of mammoth tooth. I have soaked the tooth, removed debris/algae with vinegar, rinsed thoroughly and have the tooth soaking in the toilet tank. I plan on following Harry Pristis' advise on consolidation found in previous posts. I am leaving on a 2 week trip and will not have time to dry the specimen and complete the consolidation before the trip. So the question is, should I leave the tooth soaking until I return or remove the tooth from the water and allow it to dry for the 2 weeks in a controlled manner (In a ventilated aquarium resting on sand)?

Does anyone create fossil prep videos/ tutorials. Or do you know of any videos worth a watch? Would be great to expand my knowledge and enjoyable to watch others work!

I probably should have started this thread years ago but better late than never. Ive got a bunch of fossil fish im going to prep out this summer. Im going to start with a Priscara serata that my sons friend found just last week. This serata has another right on top of it but missing some of itself so its going by by. This fish is from the bottom cap of the 18 inch layer and is in some very dense and very hard rock. The stuff I really like!!! A lot harder to prep than the split fish but nicer fish to say the least. Much harder bone too and can stand up against even pure dolomite! My kinda stuff!!! So, here we go........ RB This is the way it came up from the slab lift. You can see the other fish that is on top. The bottom one is about a 9 incher. This is almost 5 hours of work. The tail fin is a really hard prep job to say the least!!! but lookin real good so far. Luckily there is a tad bit of matrix between the fishes!

Okay, so everyone else is doing one it looks like, so I figured I would jump into the fray.
