I’ve been out of the prep lab for a week with an illness that knocked me on my rear. Yesterday, I got back in the lab and got to work on the initial prep on a large turtle from the Green River Formation. This beast is about 5’ long and came from the Mini Fish Layer. The matrix is a bit sticky but the bone quality is exceptional. It was found with a skidsteer while clearing loose rock at the start of last season, so it’s in multiple pieces. That makes it a more manageable prep but it would have been cool in one piece! This little guy is going to take me several months to complete.

I had recently received a couple unprepped oreodont limb bones from @snolly50 and have started prepping them. Here's a pic of my workstation There's been a lot of repair in these bones that I had to do. The bone on the left I'm pretty sure is a humerus. Here's some more pictures of that one Then there's this other bone that I'm working on repairing and prepping, I think this might be a femur? Then I have this piece that looks like the end of the tibia and fibula with some tarsals. And last I have this unidentified limb bone end, about 3 inches long

By some vast, cosmic alignment of karma, snolly has become the possessor of a horde of material, deaccessioned from a museum's abundance. Information is scant, but "Oligocene" and "Nebraska" are offered as clues. The foil wrapped specimens had apparently lain in benign neglect for a a generous span, the bone rests in pieces with sheets of dried, peeling consolidant and crumbling matrix. The specimens appear to be limb bones and Oreodont is the donor that presents as likely. At present, snolly is leisurely joining the puzzle pieces and removing old consolidant (white glue?) and mat

This 2" claw arrived in the mail broken, unfortunately. The seller has offered to either refund me in full or give me a discount if I decide to repair it myself. In this case, what's my best option here? Regarding repair, is there a certain type of paleobond that would work best? I'm worried about the interior because it's basically that Moroccan sandy stuff and it's very unstable. I do currently have PB750 on hand.

After rebuilding my prep station to accommodate working with my new microscope, the final part was to upgrade my air delivery with a super-sized desiccant filter. I was tired of changing out my desiccant beads 2 - 3 times a day during heavy use, so I made a DIY filter using a home water filter system. Now instead of using 4 ounces of beads, I have 4 pounds! That should finally give me a decent interval between changes.

Finally able to upload the pics of the finished prep box! Shows the way it opens for loading, the LED light strips with power switch and pig-tail plug for my shopvac so it all comes on together. Also have a small mag lens for preps where I don't need the microscope level of zoom. Now I just have to finish redesigning the air supply. Also, I may have just won the lottery. Waiting to hear from the company for a shipping quote. --- Side note, the purchase price was $50.00! I think a mod edit

Here is a crab prep video I did last week. Not only had fun making the video but I remember having fun prepping this out. It was quite the challenge. 3 minutes 34 seconds. https://youtu.be/w6Sw-FdlIlQ

How to make something for supporting my arm and something for supporting fossils for use while prepping?
fossilhunter21 posted a topic in General Fossil Discussion
Hey everyone! So I have heard from many people that it is good to have something to support your arm and something to support your fossils. And I just thought I would ask everyone how they made theirs, what they used, and maybe what they look like? Thank you in advance! -Micah -
Here’s a tease of one of my upcoming prep projects. It’s not next in queue but it’s coming soon. I spent some time doing exploratory prep on it for the last couple of days. Anyone know what it is? I’ll give you 2 hints. It’s from the Green River Formation and it’s not a fish.

What air scribes are compatible with the Paleo Aro 2.5" stylus?
Trilobite Enthusiast posted a topic in Fossil Preparation
I am new to fossil prep, so I figured that air scribe tips would be highly cross compatible. I recently bought two air scribes: one Chicago scribe and one Fossil Shack air scribe. Additionally, because I read it was good, I bought a Paleo Aro 2.5" stylus. It is very sharp, which is excellent, but when I tried to put in in either of my air scribes, it was too wide to fit through the head hole. Would I need to get a whole different air scribe to use the tip, or would I be able to attach a head from Paleotools to the Fossil Shack scribe I already ha -
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.

I guess this is my first prep. It's nothing spectacular, but it's what I would consider my first official go at it. I specifically picked up this fossil in the field in order to try my hand at prep work. It's a single ventral/pedicle valve of the brachiopod Hebertella sp. I figured it would be something good to start with as it is small, a shape I am familiar with, and a fairly common find in the Upper Ordivician exposure that I have been hunting. So if I messed it up I wouldn't be too broken up about it. The matrix is brittle and flakes away easily. Before Photos:

I've been on a ghost shrimp claw kick lately, working through the concretions that I collected over Presidents Day weekend (February 21st for all you non-Americans). This one came out pretty nice! Species is Callianopsis clallamensis from Washington State. Prepped with a Dremel 290.

What are some good fossils for practice with prep?
fossilhunter21 posted a topic in Fossil Preparation
Hey everyone! So I keep buying fossils that are not good for someone who does not have a lot of experience with prep. And I was just wondering what are some good fossils (and locations) for someone who does not have much experience? I am thinking that I should have asked a while ago, but I did not think about it until now. Thanks in advance! -Micah -
Hi, this is a bone block from port Mulgrave in Yorkshire, is the exposed bone Ichthyosaur, and if so is it identify able which part? My uneducated guess is rostrum or ribs. Is this fossil something that could prep ok?

I am in the process of designing my new prepping blast box, and I decided to make a cardboard mockup. After the advise members gave in my last thread, I tore apart my work bench, and rebuilt it lower to accommodate a box. Since I am just about to pull the trigger on a boom microscope, I wanted to wait until I actually have it to make sure the working height, depth of field, etc are all going to work with the box before actually making it. I used @Malcolmt box design with a slight mod. The box is 24x20. I thought about making it larger, but I decided that was probably

OK, I missed the Fossil Friday post by a day. The cold weather lately has kept me indoors and away from fossil exploration, so here is a partial prep of a partial ammonite from the Lake Texhoma Duck creek fm. Prepping something no true separation of "fossil" and matrix is quite challenging, especially considering how well they can, at times, weather out and become separated naturally. The matrix seems to be getting harder to separate as I move toward smaller sections. I can make out that this does have the inner whorls , so I dont want to blow them out. This has really slowed me down on t

Hey everyone! So recently I purchased some unprepared Moroccan trilobites. I am having a very hard time preparing them and am making a lot of mistakes. And I was just wondering if these maybe are not the best for practice for a beginner, or is it just me? Thanks, @fossilhunter21

A few months ago Ken @digit, had a post looking for Florida turtle specimens for a Flmnh project. A week later I went to the Peace and found this Apalone softshell. I hoping Ken post requests for a carnivore project next. After the Tampa Club fossil show this guy's new home will be at FLMNH. I also have quite a few vertebrae to prep as soon as I find some time.

I took a break from working in contract preps last night and spent an hour with the Super Jack attacking the crab that I got from @Doctor Mud. This far, the crab doesn’t appear to be sticky or covered in calcite.

Hello gang! With a repaired ticker, a solid bill of health and a finally completed off road capable vehicle; I am starting the planning for my annual July “super excursion”. As I purchase supplies and provisions I am planning to add various PaleoBond products to the mix. I’m looking for anecdotal information on the stability and shelf life of these products beyond what is in the documentation, this will help me determine what sizes/volumes I will buy. Discussion?

@Nanotyrannus35 just sent me a handful of Lance Formation bone fragments to prep. They were mostly turtle shell and we’re pretty fragile in the loosely consolidated Lance Sandstone. A bit of time under the microscope with the micro jack and some low pressure abrasive worked wonders on the bones. They got a healthy dose of Paraloid B72 stabilizer and are headed back to their home today. Some before and after pics are below.
