  1. Now that Snollyfish and the Oreodont Smoothie are done, the next project is another fine specimen belonging to our very own @StevenJDennis. I swear, he has all the luck and a collection to rival the Smithsonian's. This little baby is a nice phytosaur snout. It has really brittle teeth and hard matrix (exciting combination), so fast removal with the CP9361is out. The Aro is almost too much and I'm having to be extremely careful around the teeth with liberal use of PVA consolidation. It has had previous "restoration" done with what appears to be wood filler on several breaks. Thankfully, it appears to be holding on well so I'll only mess with it to finish it up. Here's a pic of it before work started. And, here's how it sits currently after 4 hours of prep. The distal end will eventually be reattached.
  2. I'm just curious to see what all your pros are working with. My station is pretty much complete, I have a limited area in south tampa. I've seen a lot of the air abrasion boxes, and I'm curious, what's the point? Why not just use a full face APR, gloves, and call it a day? Anyway, SHOW ME WHAT YOU GOT!
  3. Recently acquired this piece of rock with some jaw segments, vertebra and teeth in it along with a squalicorax tooth. What is the best way to prep it for display? Should I just leave it alone?
  4. Looking at different compressors, some are 2hp and some 2.5hp, some have 7cfm and some 9.3cfm would these make a difference when prepping do you think ? Any real noticeable difference ? Thanks
  5. Hi I read that some collectors give some of thier ammonites a light rub with clear bees wax too bring out a nice lustre. I was thinking my trilobite block may benefit from this as it is a little bit of an ugly arrangement and not the prettiest of fossils but the wax may make it stand out more .Any advice from the good people of fossil forum will be appreciated . Thanks Bobby
  6. So, I had a Greenops boothi that was missing the the glabella and the entire left portions of the cephalon. @ischua and I dug this fella up at Penn Dixie in the fall. I decided to finally have a go at him to see how much could be salvaged. Here's the before: A little more work: A little more: And, finally: For size:
  7. hi, i bought this big ammonite to prepare, a megalytoceras maybe, any suggestions? i dont want to ruin it.
  8. Hello all fossil-friends! (I'm not sure whether this is in the right thread, if it's not I'd love the admins to put it where it's meant to be .) Anyways, I wanted to tell everyone that their is a big fossil market at Ede (Netherlands) this weekend, and that I would love you to come! It is organized by the Paleobiologische Kring van Nerderland/Vlaanderen (Paleobiological Group of Netherlands/Flanders), the Werkgroep Fossielen Wageningen (Workgroup Fossils Wageningen), and the famous Fossiel.NET (basically a Dutch version of TFF); many other organizations/museums will be there too. There will be plenty of stuff to do: amateur-paleontologist encounters, fossil IDing by experts, fossil trading, fossil buying/selling, lectures by paleontologists, prep demonstrations, and many other fun fossil-related activities/workshops! Here's the info you need to know: Date: Saturday 11th March 2017 Time: 10:30 till 16:00 Address: Het ROVC, Galvanistraat 13, 6716 AE, Ede, NETHERLANDS Entry fee: FREE! Stuff to bring with you: fossils you are willing to trade, to prep, to get IDd, etc; and some money. No food needed (drinks and food available). Here is a link with all the information you need: https://english.fossiel.net/beursede/ BUT: this is only for fossils, so NO minerals, artifacts, etc.! I will of course be there, and I hope that you will also be. I hope to see you there! Max PS: I'm not an organizer or anything of the event, I'm just telling everyone about it so that there will be more people to meet.
  9. Hi, i'm doing some practice of fossils prep, like i wrote in the title im looking for some unprepared fossils , better if from uk or europe. if someone got some let me know. thanks!
  10. Hi Folks, I did not take a true before picture so I am sorry, but here is my work on a branching stem. The sandstone matrix is very hard and breaks very randomly. In this case, I think due to winter freezing and thawing with moisture, there was a natural crack where the rock split and another that can't be seen in the photo that greatly aided the prep. I used a dremel with a carbide burr to ensure the crack would end where I wanted to and not spread into the already exposed fossil. I also have the counterpart to this fossil so I wanted to see what I could get. The first photo is the fossil with the removed pieces put back on. Second is the revealed branch, and third is a close up of the other fossil that showed up in the split. Some kind of textured bark impression or larger branch.
  11. I bought a slab some time ago, and have finally gotten around to prepping it. (Note, I do not have an air scribe, so it takes quite a bit of time) Current Progress: (20 minutes) Only the vertebrae and a few ribs are visible here. I have noticed as I am going along, it is much more difficult than it appeared when I first purchased it. The skin is fairly intact, though there are some patches that are missing. Use a gum eraser to help clean away the dust because it is gentle, particularly on the fragile bones. All I am using is a small hand prepping tool, and though it is time consuming, it still works for me.
  12. Here are copies of images that Kris posted in the "Auction prep" topic. The slab he is prepping contains this large plant fragment. I have scanned Grande's text looking for a match, but have had no success. Does anyone have a clue as to a possible donor of the fragment? Also check out Kris' interesting prep series on this Notogoneus specimen.
  13. @StevenJDennis brought me quite the project. It's a central Texas mammoth tusk that is in terrible shape! Texas tusks are as close to the complete opposite in preservation as compared to Siberian or Alaskan tusks. They are always brittle, broken, and just looking for an excuse to fall apart. Props to Steven for rescuing this monster from a terrible fate in the back of an old man's shed! The pics below show the tusk in the sate of preservation as they arrived to me. I have spent the last week with the fragments on end literally pouring medium viscosity PVA solution (about as thick as 20w 20 motor oil) into the cracks in an effort to stabilize them. 1 gallon later and they are beginning to toughen up a bit. PVA application will continue until the fragments will no longer absorb the solution. Then, I will attempt reassembly of the fragments. Unfortunately, there has been serious degradation of the fragments in many places. More to come!
  14. Hi, I'm wondering if anybody can provide any insight about this fossil I'm attempting to prep. It's from an abandoned quarry in northern Illinois where I've found lots of Silurian Calymenes, but I'm not sure what this is. I'm paranoid to continue prepping without knowing more.. any ideas?
  15. 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!
  16. Just spent the first morning in the new workshop playing with some bugs. Thought I would share day 1 progress. Eldredgeops rana after first prep session. Greenops boothi after some basic prep. Missing the cranidium and left librigena unfortunately. Tiny little Eldredgeops rana, with another little cephalon in association. Thinking this one has the potential to be a nice multi. Usually when I find these tiny little fellas this close together it's a mass mortality.
  17. hello, looking for your expert advice. i would like to do some touch up work on a fossil to bring out more details. it is a keichousaurus in a hard slate material. i mostly want to work on the head and rib areas. i don't want to mess it up so looking for something safe for fine detail work, would something like this work? https://www.amazon.com/Paasche-Airbrush-AEC-K-Abrasive-sprayer/dp/B001CJIHFI/ref=sr_1_1?s=miscellaneous&ie=UTF8&qid=1482120215&sr=8-1&keywords=Paasche+air+eraser
  18. Hi Everyone, I'm new to the prepping world and have a couple of questions that hopefully you can help me with. I have a number of Pennsylvanian aged plant imprints that I found and I am wondering if there is any prep work that needs to be done to keep them in pristine condition. As of now I have not done anything to them. These fossils are on dark gray slabs of shale and are a bit hard to see without proper lighting. Questions: 1.) Is there a way to highlight the imprints on the dark shale to make them stand out more? They're a similar color to the shale and are hard to see without lighting. 2.) Is there anything that should be done to help preserve these imprints over time? For example, should these fossils be coated in anything to help preserve them, or am I okay leaving them as is? As always thanks for the input!
  19. I searched the forum but i couldent find any posts about different techniques for removing super glue. I have a few pieces that for whatever reason were glued the wrong way or moved slightly when drying. Im wondering if there are some good ways to go about removing super glue without damaging a fossil? I have a few ideas of what might work but im curious what people have tried and what works? In this case im working with four or five pieces of bone that were glued together but one or two are off.. Nick
  20. Hey guys and gals! Went out on Sunday to a new site and had a look around. Managed this! I didnt bother plastering this as it was all in loose pieces. There was a 4th piece under the sand and, just above the right hand side of the digging thing you can see another bit of bone - i don't know if its related but i need to go back and get it. So here is the bit at the top in the above picture. And having cleaned it up i realized i needed to leave matrix in the tooth sockets to support the weak bits that hang out. Lesson learnt and i'll do that on the next section. You can see where i ended up leaving some matrix. Also the jar is paraloid. This bone is weak and chalky! Fortunately, as i get closer to the front there is more bone and it's more intact. Here is the next piece along, viewed from the top and showing the sockets. (i'll clean them out a bit to show the shape better) And here is how the 4 pieces go. The front 2 and the back 2 will join well, to each other, but the middle may not. Hoping they will but doubting at the moment.. Too much matrix to tell right now.. Its sort of a sandstone. Bit sticky and annoying. Getting there though. Thats all for now. I'll do more on the 2nd piece tonight and hoping to have it finished by Sunday. Cheers.
  21. Well I finally started repairing the shell I got in Denver. Starting with the bigger parts, with obvious placement and working out. Currently holding a part as the glue dries Im using a 5 minute epoxy on these two sections, mainly due to difficulty holding long enough for a 30 minute or two hour one. The shell is not as yellow as in this picture. warning, this will be a long documentation of my work as I go along
  22. So i still collected this massive shell, but it is (like most of the shells I find) in pieces. I need advice on what glue to get, to best repair it. It definitely needs stabilization, and the rock is broken in to multiple parts. So far I've had no luck glueing the sandstone
  23. Hey all. I've been practicing a lot with my aro on brachiopods and think I'm ready to tackle some of the more interesting pieces I've been saving. This one is from a stream in White Sulphur Springs, WV. I don't know the formation, but I believe that the brachiopods I am finding in this location are Devonian. I think this might possibly be fish? The matrix is a very hard sandstone. My plan is to cut lines with a masonry blade on my angle grinder, pop the pieces off with a chisel, then get to work with my aro. Any advice before I get started would be appreciated. I'm excited to see what's in there .
  24. Does anyone have experience with ultrasonic cleaning of small fossils?
  25. I have been wanting to make this post for a while, but haven't gotten around to actually getting good pics until today. I have got myself one of the better Platystrophia brachiopods from my Nashville trip in August. It has a good bit of gunk stuck in the radial ribs, and I would at least like to clear a good bit of it out. Any cost effective tips? pics: Pedicle valve Brachial valve
