  1. Elasmosaurus Tooth Repair

    I received an awesome set of Moroccan matrices from @caldigger (thanks again!) that included a cracked elasmosaurus tooth. I didn't consolidate the tooth before prepping, as the matrix surrounding the tooth was far harder than the rest of the block, leading me to believe it had been sufficiently consolidated. It split at the crack whole handling it before prep work even begun, so I continued with the rest of the tooth and got the rest out pretty cleanly. The fossil isn't valuable, so I'm not too worried about perfection! Its all part of the learning experience for me. My question is about the correct order to go about repairing this tooth. When you line up the pieces, there is still a small hole from a missing section, and I suppose filling it with the matrix and then adding a layer of Paraloid dilute would be the best way to go? So here is my (tentative) plan of repair: Consolidate the pieces in the dilute Super glue the bits back together as cleanly as possible Fill in the cracks with wet matrix (?) Let it dry, then gently coat again with the dilute solution Would exposing it to the dilute twice be overkill? And I know acetone tends to dissolve super glue, but I assume the glue would hold if it's inside the tooth and the second coat of Paraloid goes on just the outer layer after it has all dried? Hopefully I explained my intentions well, and I'm looking for ideas as to what would be the best order to attempt these steps in or otherwise a preferable method (if there is one) of repair!
  2. I am going to feel bad if there is already a post with as much information as I am looking for, but I can't seem to find one. Essentially, I am having a hard time finding the proper consolidation materials. I have never prepped before, and I am going to be starting my first project this weekend. That being said, the extent of my knowledge of sealants comes from research on this forum. I am looking for the right materials to use (with or without acetone dilute) to keep my fossils from being damaged while working on some Moroccan matrix. I'm not finding anywhere reliable to purchase PVA B-15, Butvar, or anything of the sort. Is there a more easily accessible material I can work with? I need very little at this point in time, and not necessarily something expensive or overly high-quality as the items I will be working with are small and cheap. What are other alternatives that people use, and what are the benefits of each of them? I am eager to know all there is to know, and I've been slowly going down the list of each of the topics in this thread hoping to find what I'm looking for!
  3. Hello everyone, I was wondering what tools people would recommend for fossil preparation, I am an absolute newbie in this area and am not familiar with what options there are out there but would really love to learn, so far I only have a pin vise which I have used on rough matrix removal but too scared to get close to the actual fossils. Thank you, Misha
  4. Hi all! I am new to the forum and relatively new to fossil collecting. I would like to try my hand at preparation, but am not sure where to start. It seems like purchasing mosasaur teeth still embedded in matrix and slowly working to get them out might be a good way to practice with cheap and easily obtainable fossils, but I do not know how to go about this. In my head I imagine purchasing a few 20-30 dollar teeth with matrix, chisels, and scribers to be a great and (relatively) cheap way to begin practicing various techniques that I intend use for the rest of my life, is there anything else I need to be aware of, or perhaps other recommended forms of practicing preparation and removal of fossils from rock for beginners with a plethora of patience/time? Hopefully this makes sense!
  5. Lance formation matrix fun

    I had picked up a box full of Lance formation matrix bits a little while ago. This evening while in the garage I couldn't fight the urge to poke around a bit at a couple of pieces. I probably should only focus at one at a time....but temptation. I didn't really mess will the champsosaurus vertibrea in the matrix. I broke out the dental picks and started to play with these chunks. I didn't stay out there long because it doesn't have heat but there are some interesting things that are exposed. Hopefully I can get a spot in the basement set up so I can get deeper into this. I don't know I this fits better in the fossil hunting section or the fossil preparation section.
  6. Triceratops Tooth in Matrix

    From the album Lance fm. Microsite Finds

    Triceratops sp. (horridus or prorsus) Late Cretaceous (Maastrichtian~ 66 mya) Lance formation
  7. I am offering up some Lee Creek micro matrix up for trade. I looking to trade mainly for other micro matrix, nothing that can only be sorted with a microscope please. I will entertain other offers as well. Adam
  8. Hi folks A selection of Silurian goodies. In exchange, I'm looking for dino teeth (NOT Moroccan unless exceptionally pretty). Overall images. Oh, Roman coin included for size. Coin is 1cm
  9. Red Hill Matrix

    Hi everyone! I have what I was told is Red Hill matrix that has been sitting on my porch for a very long time now... Anyone familiar with this matrix that can help me out? I am wondering if it does in fact look like Red Hill and the best way to break the matrix down? Some are very large chunks that have too much quartz to dissolve I think but here are some of the smaller pieces. As you can see there's a lot of shells in there... lol Any feedback appreciated! Thanks in advance.
  10. Lee creek matrix, micro teeth ID help

    I found these, amongst many others in some lee creek matrix. I was hoping someone could identify them for me.
  11. Tooth cleaning

    This tooth can be cleaned off more than this, cant it? It looks like there's plenty that is layered on top of the actual tooth that should be able to be removed, but I know it's not always as easy as that. And of course, not just if it CAN be removed, but removed safely? More to the point-safely by an amature?
  12. Unknown Insect? on Matrix from Ningcheng

    Hi folks, I received this in the mail as a bonus for one of my purchases, it's a matrix from China (browsing for similar specimens from the seller places it as from Ningcheng, China, Jurassic period). I have zero idea what it is, and wondering if the wonderful TFF folks have any indication of what it could be? I doubt it's anything (and without a microscope, probably impossible to identify), but trying to make an attempt to label it, rather than dumping it with in my unknown bucket.
  13. Matrix Identifcation

    Howdy! I'm having a heck of a time identifying the matrix surrounding the fossils I'm finding in my dig site. I'm using vinegar but it is weak. I'm considering using CLR on some practice stone plates but I could use some guidance.
  14. Help with Lee Creek Micro Fossil Tooth ID

    I was going through some Aurora Creek matrix, and I found that this tooth was a bit more unusual than the rest. Its root is a bit wider and its blade is shorter than the other teeth I have found. I'm thinking it could either be an angel shark tooth or a hammerhead shark tooth.
  15. Finding fossils

    I live in Kansas and thought I had a lot of fossils. Well, I guess not. Is there a type of rock that houses more fossils than others? What signs (crystalization? ) a color? Etc should I look for?? Are fossils typically a certain color? Does anyone have fossils still in the matrix that they could post here to help me know what I'm looking for? Please. Thanks!!
  16. Hello everyone, I have been collecting fossils for almost two years now but even incthis short period of time I have amassed a large collection. Unfortunately bringing home slabs of rock home atleast a couple times a month starts to fill up the house and does not bode well with my parents. Still being 15 I do not have a lot of space for the fossils so my dad and I have started cleaning through the garage soughting through the large slabs. To also tackle the storage peoblem I have started collecting smaller fossils (Shells, teeth, etc) and have now taken an interest in micro fossils. There is a couple sites in Victoria and South Australia where you can collect micro fossils (Small gastropods, bivalves, echinoids) but I am looking to buy some micro vertebrate fossil matrix. I have been looking around a couple places and have found a store with some good reviews (D and D Fossils). Is there any other places I should check out? Also I am happy to trade for micro fossil matrix if any one is interested. Thanks, Daniel
  17. What is the best place to buy fossil matrix with the most fossils?
  18. I found this shell cast on Honeymoon Island, Florida, USA. As you can see from the photos it's a complete shell cast and measures about 4 x 3 1/2 inches. I did some research and found similar pictures that looked like Turritella Shell. Would the Forum agree with this ID?? If so I read that this is an extinct species of fossil sea snail. Is this correct? I appreciate your feedback. Thank you!
  19. Yesterday I went over to Bakersfield ( Sharktooth Hill locality) East of the river. Just for kicks, I grabbed a small amount of matrix chunks to see if any small fossils could be found. Fast forward to my prep lab ( kitchen) for a cleaning. I was surprised at the abundance of tiny fossils in there and they have the same coloring as the larger teeth.lots of reds, yellows, sable browns, etc. Tonight I did some sorting and looky what I found. A very small Cow Shark tooth only 6mm long.
  20. Mystery fossil tooth in matrix

    Hello all I recently found this at a shop with really no information on it. I am in Texas, but not sure where this fossil tooth in matrix was found; or if it is even real. The matrix looks and feels a bit weird to me. The tooth itself is about 1-1/8" long with what looks to be a long root under the matrix it is on. What do you think? Any suggestions or info would be great! KP
  21. I found this Psittacosaurus specimen online, pretty positive it is a real fossil, however not sure if this is really a Psittacosaurus for various reasons. Here are the pictures associated with it, it was pretty vague with no location to where it was found, which is why I am posting it in the is it real because of lack of information.
  22. Hi all, I acquired this piece, did not find on site. It seems to be basalt but the outer matrix is packed with sand and shell fragments. The brachiopods (I am assuming from the research I have done) are rather large, and appear in a cluster. Some of the fragments I have observed appear to be from the devonian era. I am assuming this is a steinkern vs true fossil. But the matrix is so fragile to clean it is destroying it. I am more of a rock hound than true fossil student. I have learned from some of my earlier posts last year that if the structure has been replaced by silica than it is not a true fossil ie steinkern, I believe. The matrix includes so much sand and shell fragments that it makes me question how silification works? Some of the shells, brachiopods, became irridescent as the stone absorbed moisture. Looks more like stone when it is dry.. . One of the pics that looks like brushing its teeth, has an opal in the background that I believe is the actual metamorphic process from this exact type of matrix and brachiopod by water and silica ooze. Interestingly as I have been cleaning the opal up also, it has the same structure as the outer pieces of the shell from the brachiopod, feather like. The striations in the opal also seem to be where the brachiopod foot would be... and also the richest mineral and most beautiful layer... Any ideas of what I should do with this piece to clean it or leave it alone I would love. If you have knowledge about brachiopods and opals I would love to hear that as well!! Thanks Kim
  23. I'm looking for a nice Otodus tooth on matrix. This one is described as "still embedded in the natural rock it was found in." It is 2.5". Does this look naturally attached or glued on to you all? Thank you.
  24. Hollow Reptile Egg Fossil

    Hey guys! I'm curious about this egg fossil I've got here – it's been preserved with its hollow shell intact and sort of crystalized. I know there are loads of these eggs out there, but I've never seen one like this before so I'm wondering how unusual it really is. The other egg seems to be solid when held under a bright light. Here's what I know about it: – Ophidienovum sp – From a snake, I think – Tertiary/Miocene – From Mainz, Germany – Eggs are 2cm long Would love to hear your input!
  25. What is in this Devonian matrix?

    Any idea what the other items besides the trilobites are in this Devonian era matrix? Especially the anchor shaped item. Sorry I forgot to put something for size reference but you can kind of get a idea from the pair of scissors in the pic.
