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.

On an annual basis we get one day to collect in a pretty amazing quarry in Bowmanville Ontario. This year 2015 was no exception. My buddy Dave here on the forum had a pretty amazing day. I suspect many of us would kill for even one of the specimens he found that day. I just realized that I have never posted how his fossils turned out. Turns out he is popping by this weekend to pick them up before a mineral and fossil show up in Peterborough Ontario. Fossil Forum member Northern Sharks is a very active member of the club (Kawartha) that is holding the event. Here are Dave's finds for the day as found. They are all isotelus A pretty damaged isotelus .... but a large one A nice Double Another nice double A nice single

After prepping my first ammonite I decided it was necessary, before starting another prep, that I would need something to catch all of the dust and debris. So, inspired by ZiggieCie, I went DIY. However, unlike ZiggieCie, I couldn't boast about $0... I had some scrap 3/4" plywood in the garage, which I put to good use. Most everything else I had to purchase specifically for the project. But it gave me the opportunity to buy tools I would need for other projects! I mounted an air manifold to split my air supply between my CP 9361, my Harbor Freight air eraser and an air gun. I hooked my Rigid vacuum into the side to collect the dust. Below is the result... All I need now is some dolomite for the air eraser. I'm planning on picking up a 50 lb. sack from a ceramics store in Houston. I can't wait to get started. I have some other ammonites to get to!

I have a question. Does anyone have any knowledge of anyone attempting to use color enhancing sealers for stone and tile to bring out the colors on a fossil? I did tile installation for about seven years and we used it to bring out the colors in travertines and such. It gave the tiles a "wet" appearance, without the shine. I know it wouldn't take the place of a consolidating sealant like Vinac or Paraloid, but it might make the fossil stand out against a matrix, if the colors of both are similar. Just a question I've had, bouncing around my skull for awhile...

I finally got frustrated. I have had a CP-9361 air scribe from Amazon and a Central Pneumatic Air Eraser from Harbor Freight in my garage for almost a year. Both were still in the box.....until the day before yesterday. I had wanted to build a spray cabinet, but just haven't gotten around to it. I broke out the air scribe and started tinkering with fossils that I felt like I could practice on. Once I felt more comfortable, I decided to tackle an ammonite that my dad had collected years ago. The inner whorls were covered by a chunk of matrix that my dad had attempted to cut into with a rotary tool. He gave up quickly. Below are the before and after pictures... Before... After... After I was finished, I decided that, perhaps, a spray box would be beneficial. There was chunks of limestone and dust all over the garage! Also, I'm not sure about the ID of the ammonite. I don't know where it was collected since it has been in a box for perhaps 40+ years. If anyone has an idea of the genus, I'm all ears... Daniel

I really like proetida, and this one caught my attention because it was a bit different. It is from the region of Foum Zguid, Morocco. The cross-section reveals quite a bit, and shows some sort of Diademaproetus-like trilobite. Only, a lot of details are really off, for example the preglabellar protrusion is missing. The proetida is a surprisingly divers order, but the devil is always in the details, so it can be quite challenging to identify. But first, prepping it. The bug is covered with numerous small tubercles. They tend to 'grab' the matrix, making the preparation much more challenging and time-consuming. But patience pays off, as you can see in the second picture. You can also see I just discovered the left free cheek with the eye. It is slightly dislocated, but that is not unusual.

I know back home people are fond of prep stories, so I though it would be nice to present one here. It is an ongoing preparation, so any progress, ...or any problem with the specimen, error from my side, etc.. will be reported almost live (I'm already a bit further, so I have to catch up a bit here). The specimen is a Cyphaspis trilobite from the El Otfal formation in the Moroccan Ma'der basin, which I found on my last trip there. The first pic shows the specimen as found: as a nice cross-section in solid limestone. You can recognize the head ('cephalon') to the left, and several segments to the right. The cephalon cross section shows a wide cephalic border and the large glabella with numerous tubercles, both very typical for this genus. Some Cyphs from this couche are known to have 4 characteristic spines or thick tubercles on the glabella. It is good to know or suspect such features beforehand. It is easy to damage such features when you're not expecting them. In this case however, there is considerable variation in these features, so the exact shape, location and dimensions of the spines were a surprise. Therefore, I had to advance with great caution. The second picture shows the frontal view with these 4 spines exposed. So far, so good. Next, I advanced to check whether the right librigena (or free cheek) is in place. Trilobites molt by shedding these, so they are often missing or displaced. It is there, and only slightly disarticulated, which is good. The presence of the left librigena was already clear from the cross-section. Can you spot it? Interpreting these cross-sections takes some of practice. The last two pictures show the exposed right librigena and stalked eye.
