    Simple Homemade Display Stands

    Thought I would share some simple, inexpensive display stands I made for some of my smaller fossils. I don't suggest these are museum quality, but hopefully this will encourage others to experiment. These fossils were in my display case but just lying on the floor of a shelf. I didn't feel this was an optimum way to display them. I wanted to get them up off the floor, but I didn't want to spend a lot of money. So I decided to go with a simple wooden base together with some brass rod I bent to shape. The wood came from a 1x3" piece of red oak, 2 feet long, that I got at the local Osh hard
  2. I have been prepping for nearly 7 years and work on private contracts. I used to work in a museum where they have been using the same methods since mid-2000s so I was taught to prepare using the techniques and tools that they taught me with (and developed my own skills for micro-preparation), namely just using a pneumatic scribe (ME-9100, CP9361, MJ) and a microscope. I've been curious about chemical prep, and was wondering if someone could explain to a complete newbie some of the ins and outs of the method? Or direct me to any forum threads/good websites that explain it. I want to broaden my

    Donatello the Tortoise

    I’m excited to finally be able to do a fossil prep post here on TFF. In addition to the Fossils on Wheels stuff, I am also a Supervisor at the Gateway Science Museum here in Chico. I’ve mentioned that the Gateway has some pretty special fossils right now that will become part of a fossil exhibit in the fall. Some of the fossils are getting quite a bit of attention from media outlets from around the world. These fossils come from the Miocene Merton Formation of Central California. Most of the prep work is being done by faculty, staff members and students of the Geology department at

    Air Scribes

    Hi all, I was wondering if anyone could give me advice on 1. air scribes you’ve found are good for fossil prep, and 2. All the parts needed for Scribes. I’m not quite sure all the parts needed for a scribe, I know you need the scribe itself and an air compressor, but I don’t know beyond that. P.s; the fossils I’ll be working on will be Green River fish, for the most part.
  6. Hello All, I acquired a Odontocephalus fossil that would benefit from matrix removal (limestone) especially on the cephalon. I was hoping for some references in the US? Thank you very much! Wayne
  7. I don't know if this has been addressed, but do you want to prepare fossil WITHOUT an airscribe or compressor? The Dremel 290 is bulky but there is an alternative: CH Hanson 50002. It acts like a mini jackhammer instead of rotating like most other rotary engravers on market. You can get 3600-7200 SPM (Stroke Per Minute). You can control the speed, and power by turning the knobs on the top. Super easy to use and I use it to prepare fish fossil. The stylus has a really small point too with diameter stylus 1/1/6" or .062 in and can be easily changed. So you if you want to prepare fish fossil

    Phevo's prep thread

    A year and some ago I bought a Krantz W 224 airscribe to start doing some mechanical preparation and promised to do a prep thread once I got started. Prior to this type of prep I have done a lot of silicone casting (which I might make a separate thread for) and on softer matrix used a mix of dental picks/tooth brushes. I have had several different setups over the past year, and the past 2 months or so can be seen on the following picture After spending a tedious amount of time with the rough matrix removal I decided to add a Cp9361 airscribe, which has sped
  9. Does anyone know of a resource/person for prepping an articulated, out of the matrix ceratopsian? Skull intact. Near complete animal about 3.5 ft long. Looking for someone with experience. I'm in the San Francisco area - North Bay (Marin,Sonoma). Thanks!

    ME-9100 lost power

    Hi everyone, Hi have an ME-9100 and I’ve had years with no problems. Yesterday I took off the sleeve and cleaned everything and the only difference to my routine was that I directly put oil in where the piston is. now I can get it to start, but there’s no power, seems like the stroke length is almost zero and the stylus is barely vibrating. I took it all apart, including taking the tool off the hose and removing the pin and checking the piston, but it back together. Had slightly more power for a few seconds. But now the same problem. Any ideas?
  11. READ ME FIRST. Every once in a while the topic of consolidants and adhesives comes up. I've attached some information that has helped me in the past. The first is a publication put out y the Society for the Preservation of Natural History Collections. The next is a discussion of consolidants and adhesives put out by Florida Museum Of Natural History. The final document is a study I did on consolidants about 15 years ago. To this day my favorite adhesive is a combination of Paraloid B 72 and acetone at various concentrations. I like this because it is reversible
  12. Can anyone explain or provide sources on methods of fossil preparation during the 19th Century? I am interested in what tools, chemicals(if any), etc., were used to prepare fossils from the mid to late 19th century. I recently read one of Beecher’s papers from 1893 with a drawing of the antennae and legs of the Triarthus he found in the pyritized Lagerstätte ein Rome NY and was curious how they prepped fossils at that time? Also, when was air abrasion introduced? Thank you

    Prep intro for a beginner

    Ive always enjoyed fossil hunting in local areas however I've never done any prep. work at all to specimes I've brought home. I've two practice pieces singled out to experiment with. (If it goes horribly wrong nothing lost) One a random chunk of lias clay with some bivalves and the other one a little ammonite just peaking out of another lump of jurassic lias clay. The matrix isn't particularly soft or hard with either. I have no appropriate tools in my possession however I'm willing to buy some basic things which are necessary. Any advice would be appreciated.
  14. Hello everyone, I recently received this large 14inch ammonite and the shipper had no care in the world to put even an ounce of protection thus this is the result I'm not experienced with much prep and not confident superglue would cut it so what would you all recommend to help repair this specimen as well as clean off some of the dirt/dust layer coating alot of it?
  15. I have recently begun my journey into fossil prep, i'm using a dremel electric engraver as it seemed to be the best cheap tool. I have several ammonites from Yorkshire within nodules - these are very hard in the centre and consist of pyritised sediment. It is taking a very long time with the dremel using tungsten-carbide point, so just asking for any advice on how is best to try and get through these very hard bits. Cheers in advance!!
  16. Okay so I have some questions on what you can and can't do with your typical trilobite in shale fossils. To help direct the discussion, I am interested in setting a small trilobite in silver as a gift. I make silver jewelry both using PMC (Precious Metal Clay) and traditional cutting and soldering. So, first question: Can you use high percentage (70% or higher) rubbing alcohol to clean all the dust and debris before sealing a trilobite? If not, what should I use? (I know you shouldn't use water) Question 2: What sealants can/should you use on a trilobite? I am looking for something that will b

    Ichthyosaur prep workshop

    In addition to my work with Fossils on Wheels, I also work for a small science museum that is part of CSU Chico and sometimes there are perks to that job. Tomorrow CSU Chico is hosting an Icthyosaur prep workshop with Dr. Greg Cole. Richard Hilton will also be there and he literally write the book on California's marine reptiles and dinosaur fossils finds. This should be a really informative and fun workshop. I know very little Icthyosaurs so this is a great opportunity to learn more about an animal that we need to learn more about. It is also a chance to learn more about fossil preparation, w

  20. Admin please move to appropriate topic if needed. :-) Fillmore County, Minnesota, USA - the most fossiliferous county in Minnesota Ordovician Mostly Galena Formation Whispering Winds, Spring Valley, MN I thought I would share some pics of my fossil barn that I have been remodeling on a budget. There are some ideas here that others may be able to make use of. :-) Overview of the outside of the barn. Note the trilobite cutout an pterodactyl toy at the peak. Galena Formation large cephalopod.

    Prepping Brachiopods

    Hello, I see all the great trilobite preps that people have done on specimens found at Penn Dixie and I was just wondering whether anyone puts the same amount of effort on any of the brachiopods or corals (or other things for that matter) that come out of that site. Specifically, I am curious whether you can use the same air abrasion techniques or if the fossil left behind from these brachiopods and corals is not as dense as the trilobites and therefore just gets destroyed by the use of air abrasion. If anyone has used a similar technique on brachiopods or corals I would be interested i
  23. I have recently been getting into the world of fossil preparation. The only tools that I have so far are a dental pick given to me by Roger Farish, and a few other picks of about the same tip size that I bought at Home Depot. They are doing well for me now with the kind of basic preparation that I am doing with the Austin Chalk. The problem that I have is trying to clear away the dust and small rock bits while I am preparing the fossil. So far I have been just blowing it away with my mouth, but in the process it is hard not to breath in some dust, which I know is not goo
  24. As above. I am considering getting a Green River fossil. The slab is much bigger than the fossil, so I intend to cut it down. However, the seller declined to cut it, saying it was a thin slab, and he feared cracking into the actual fossil. Has anyone here done prep work on GR fossils? Can I use a hand saw, knives, or scissors to cut down thin-slab Green River fossils? Or are there other methods you would recommend?

    Hi, Im new to the forum and was happy to find it. I'm an amateur geologist, and fossil collector. I have excavation experience in late Roman early Christian archaeology in Winchester England back in college, so I still have my trowel and dental tools Now I enjoy the hobbies with my son when we take a break from life in Manhattan, New York City. I purchased a Mosasaur tooth , from Morocco mines and in the matrix that it came with I was able to expose another tooth....but what is it??? Its 1.5 in long including the root. I kind of like the specimen as a clump rath
