Just finished prepping this juvenile keichousaurus and thought it was worth a view as all the bones are totally pyritized. I've never seen this on any keichousaurus before. All the bones have a burnished gold patina. Mother Nature is awesome!

I bought the attached crinoid from a dealer. It is from Crawfordsville, IN. I noticed that there is a smaller, darker crinoid stem to the left of the main crinoid, and I have an urge to prep out out, but I have almost no experience prepping. Is this something I should try? Do I run the risk of destroying the crinoid that is already exposed? Does it even look like there is another calyx buried in the matrix? Any suggestions appreciated.

I have basic tools for preparation. I tried the Harbor Freight Air Eraser with no luck and I have the Dremel Engraver with assorted points. Right now everything is on hold till I get thru information overload. I have saved enough to purchase one good piece of equipment. I have looked at a lot of stuff and now I need a push. Do I go all out and get a MicronBlaster or is there something everyone likes better?

" THE BRISTOL DINOSAUR PROJECT – A CONSERVATION AND PREPARATION OVERVIEW" from the Journal of Paleontological Techniques, a Symposium Volume covering the 1st International Conservation Symposium-Workshop. The Bristol Dinosaur Project involved extensive preparation and conservation of a large collection of macro- and microvertebrate fossils. The starting point was some four tonnes of fossiliferous cave-fill breccia, and the laboratory procedures involved a broad range of physical and chemical approaches to reduce this matrix and extract, conserve, and curate the dinosaur bones and microvertebrate remains. The initial state of the remains, and the laboratory procedures followed provide a good case study of historical collections found in many institutions that are in urgent need of care and dedicated work. The program also provided examples of good and bad practice, while training students in laboratory skills. http://www.jpaleontologicaltechniques.org/pasta3/JPT N13/pdf/JPT13_pg_50_64.pdf Have to be patient - takes quite a while to load....

More from the new workshop - Eldredgeops multi w/coral
DevonianDigger posted a topic in Fossil Preparation
So, in my previous post, "Day One In The New Workshop", I had posted a pic of a plate that I had hoped would be an Eldredgeops rana mass mortality plate. I decided to do some work on it to see if there were any more than the two hiding in the matrix. Apparently the rest of the trilobites opted for the blue pill. Turns out there was just the two, one enrolled, one prone, and neither 100% complete. There was also a nice little piece of what would appear to be Streptelasma ungula coral. I have been asked several times to "blog" about my prep work as I go. In an attempt to abide, I am going to try and share as I go with this piece and others! So, after some initial prep, it looked a little better. Once I determined that these little fellas were not with friends, I used my Dremel engraver to rough out and shape the surrounding matrix. I did, at one point, accidentally pop the lentil-sized roller off of the matrix. Thankfully, I had the foresight to hold down the actual fossils with my thumb as I was working around them, thus denying him the opportunity to experience flight. In the above picture you can see that I started to smooth out the rough cuts surrounding them. I did this with my secret weapon, the tattoo machine with a 7RL needle. As you can see in the final picture from the day (above), I started to prep out the coral and continued to contour around the "bases" of the two bugs. You can also see that the roller has a squished head, and that there is a small piece missing from the right eye of the prone. (As I mentioned earlier, neither of the two were in perfect shape to begin with.) In my next post for this one, I will show the surrounding matrix contoured out and hopefully more detail on the buglets. This is proving to be a tricky prep as they are tiny! (See below) Next time, I will try to get more "step-by-step" pictures to walk through the entire process!.thumb.jpg.3a5910d0c47d9cf4dace0d92722833a2.jpg)

Hi everyone, It'sThe Amateur Paleontologist here. I still haven't reglued my chalk fossils from Møns Klint (from MKFE N¤ 1; August 2016). Could you please kindly give me some advice as to the best glue for gluing back together Chalk fossils? Wishing to all of you a happy new year! Christian.

Hello, this is my first time using a dremel to prepare fossils. I decided to begin testing the dremel on an enrolled trilobite with partial cephalon because I thought it would the easiest and it was already missing pieces. So far I am happy with the results, however, it's very difficult to get into tight areas with the factory issued tip (also I wish I would have started on a less anatomically complex position!) Anybody have suggestions on where to find fine tipped carbide needles for the dremel? can't seem to find any anywhere..Or other alternative methods ..I can't afford an air scribe right now, so that is out of the question..... Thanks

Hi. I have a Aero tool air scribe that works for 10 minutes and then stops. I have a water trap in the air line as well as a filter on the air feed line and the tool air line. It worked great for a year. I've replaced the stylus spring and the two o-rings with no success. If I take it apart and wipe all the parts down it runs for another 10 minutes. I put one drop of oil in the tool before use as recommended. Any thoughts anyone?

Thanks to Blake(FossilDudeCo), I was able to purchase an unprepped plate back in March to try my hand at my first green river fish. It's been a busy year so it's just been been sitting on my prep table mocking me for the past 8 months. This weekend I finally spent some time working on it. Learned a lot, what works, what really doesn't, and mostly that I now want to get out to the green river formation and go 'fishing' for myself. It's certainly far from perfect and I need to get some carbide needle chisels to clean up details for any I do in the future, but overall I was pretty excited with it. It's a Pricacara Liops and the fish measures out at 5 1/8"

Hello everyone, I recently took a trip to Aust in the UK and got myself some nice chunks of bone bed with various large bones and teeth embedded in the rock. I am wondering what tools are recommened for me to try and get some of these out? I have never done this before but would like to give it a go as currently random chunks of rock on my shelf doesn't look the best haha plus it will be fun exposing ichthyosaur and pliosaur parts! I do not have a huge budget so I can't be spending thousands of pounds but I am willing to spend a little on getting the right tools. Any questions please ask. Thanks in advance Lance

Flint fossil imagery and preparation
The Amateur Paleontologist posted a topic in Fossil Preparation
Hi everyone, I'm here to talk about a fossil I found at Møns Klint. It is a distorted Echinocorys? echinoid replaced by flint. Nothing that interesting, you would say. However, on the underside of the fossil there appear to be crinoid cirri-like structures within the flint . Unfortunately, most of the underside fossil seems to be totally hiden by the flint. Do you think I should go and "bombard" the fossil with x rays at an X ray platform, so as to reveal more of the fossil? How can I "prepare" the echinoderm structures to make more of the fossil revealed and visible? Thanks for any help. Best, Christian -
My air abrader got stuffed up over 2 weeks ago, so I sent it off for repairs and I've been twiddling my thumbs ever since wondering what to do with myself It turned out that the real culprit was my compressor, which I had just had repaired a few months ago. This time it was leaking oil into the air system, thereby causing difficulties with the other tools. Fortunately it didn't bother the air pens much, but the abrader needed a complete overhaul and I've been forced to replace the compressor completely this time. I finally got everything put back together yesterday and made a dry run today on a couple of ammonites I hadn't quite finished before everything went awry. I recieved them from a British collector in exchange for some prep work I'm doing for him. I also managed to get his things finished off today as well. Sonninia (Euhoploceras) marginatum Hyperlioceras deflexum Now I'm looking forward to getting back to business as usual.

Hi ! I search a tool which can cut stones ... So for example a saw like this: http://onlineshop.real.de/Steintrennmaschine-RT-SC-570-L/0483921001001?adword=onlineshop/google/sales/PLA-S&adword=onlineshop/google/sales/02_Haus-und-Garten/(DE:SAD)_Heimwerken/&gclid=CKGPy6WGldACFZEW0wodHW8C8Q ? Is this a good tool ? It shouldnt be too big or too loud .... Thanks for your help !

I know that the recommendation for cleaning and prepping fossils appears to be an air compressor with the air engraving type tool.....but I CANNOT use an air compressor, it freaks my dog out!! So I have looked at Dremmels today and various other small tools for fine work. They appear to be only rotating tools? So can anyone make a recommendation for an electric tool for me? I guess one that can have interchangeable heads? I look forward to your recommendations

Hi all, I recently bought a dinosaur footprint, and it has a graphite outline. I was hoping it would just come off with an eraser, but it refuses to budge. I didn't want to just slap water on it and hope for the best. Is there a good way to remove the markings without damaging the footprint?? I'd love to display it natural. Thanks so much for any help!

Hey guys, Here's a few photos of some fossils that a friend of mine found in the area of Lake Texoma years ago, he has them in one section of his yard. Hopefully yall can help identify the types of ammonites and in particular the objects that look sort of like teeth. The second set of photos, in my second post, will show what resembles a big tooth that is set in something, what exactly it is I don't know. It almost appears that there is cement in between the tooth and the other pieces but I'm not sure on that. I haven't had a chance to ask him if he or someone used cement to assemble these pieces together. What do yall think?

Hello everyone, In anticipation for my trip to Kansas next week, I wanted to see how ya'll would recommend prepping specimens in a chalk matrix. I'm hoping to find some fish bones, vertebrae, and teeth if I'm lucky. I previously was able to scrape and scratch matrix off some stuff I found the last time I went with a carbide-tipped scratcher and I also used my water gun to blow matrix off of the fossils. I found some neat pyrite concretions too and was able to use dilute HCl to nicely dissolve the matrix away but wanted to avoid doing this on fossil specimens since I didn't know if the fossils would also be dissolved away. I was recommended using dental picks to remove material from the fossils since the matrix is so soft. Is there a better way to do this since I don't have pneumatic or electronic prep equipment? Thanks for your help!

Hey, this is my first post here. I'm an avid fossil hunter from northern Indiana, as well as a geology major at Hanover college in southern indiana... two great spots for fossil collecting! Anyways, I was wondering if anyone else uses hobby files to remove sediment from invertebrate fossils. Currently I'm working on removing the rock around the head of a Sphaerexochus Trilobite with the files and it's working pretty well. I'm almost positive the rock is dolomite, I chiseled the head off of a large matrix while in the field collecting one day. Just wondering if anyone uses the same method of preparation. I will post pictures of the files and the Sphaerexochus head later today.

Hi, I recently found a Pleistocene fossil on the Isle of Wight and I was wondering what the best way to preserve the specimen is? It had a small crack when I found it but it appears to be getting bigger and don't want to see it damaged any further. Thank you.
