  1. Hello. Is this matrix from Nanxiong Formation? Please tell me. Thanks in advance.
  2. Hi, JP. I saw your comment on another thread, and decided I would try it out on some White River micro matrix I have been working on, and it works pretty well! Much faster and easier! Just thought I would share some pics of the teeth I have found so far: My brother actually found a small lizard jaw sitting on top of the micro matrix. The lizard jaw is near the center of the container. I have searched through probably less than one gallon of sifted micro matrix. And to me, that seems pretty good! Cheers and Shalom,
  3. Some of you may recall that towards the end of last year, I bought myself a usb microscope. The aim was primarily to have a closer look at my amber inclusions. Also used it to magnify my regular fossils too. After having read through some of the threads on this sub-forum, I decided to delve into the realm of micro-fossils. Had a look online. And found a good deal on that auction site. 28 x 50 gram sachets matrix. Spanning various time periods. According to the seller, it is primarily invertebrate material. Am planning on getting started on the
  4. Hi. I got this random mosasaur tooth in matrix. It has this unsmooth texture, so I assume it could be an fake root. Also I see two damaged white marks. I am more interested about the crown, but I think its still good to know so I can notify about it if needed. Thank you for your answers.

    This is an Albertosaurus tooth in the matrix. Below this matrix is a hadrosaurs rib, the fossils comes from Drumheller ,Alberta, Canada There are special patterns on the enamel. Any insight on this would be greatly appreciated.

    Crinoid Matrix Removal

    Howdy! I found dozens of crinoid stems recently and most of them seem to have a thin layer of matrix attached. They were found in limestone, but I don't even know what mineral they've been fossilized in...calcite? Would I be able to remove the matrix with sandpaper and perhaps even polish them? Would sanding them remove visible segmentations? All help is appreciated, thank you.
  7. I'm trying to reduce my fossil storage space (I have a lot of matrix taking up space in many boxes). The only option I have found is to cut the matrix using a portable water saw with a diamond blade. As I'm new in this field, I'm afraid of doing something wrong. What are the rules when cutting a matrix? How near to the fossil can I cut without damaging the fossil? How much of the matrix should I keep for presentation purposes? Rectangular shape matrix are good for storage, but that doesn't feel natural to me, any suggestions ? Here's an
  8. Hey all, I have a fossil in my collection that has a fossil on matrix. I am unsure as to if this fossil was placed there unnaturally or not. Under black light no obvious signs of glue (nothing glows) Though the suspect part to me is what appears to be holes or bubbles on the rock at the base of the specimen. I guess it’s possible that the specimen was completely removed cleaned and popped back on, or it is possible that the specimen was found and later placed on this matrix. What are the chances though that this fossil and matrix go tog
  9. Good day. Recently got this mystery specimen from the owners of an extremely productive and well-known ranch in Powder River Country, Montana (please see photos). The specimen was found by the owner. Unfortunately, this specimen is not like those. Here's the only additional info: "This large piece of skull [?] was found in one piece. Weighs approximately 4 lb. 3 oz. The measurements are L 7 2/10" W 4 3/4" No repairs. Color is various shades of brown. Some of the openings actually have some matrix in them, but I left that, in order to stabilize the thin walls."

  12. I'm curious. Why are Fossils in Matrix, so Popular? Is it the impression that they are "as found", and somehow more genuine? Inquiring minds, want to know.
  13. Another recent acquisition; a beetle of some flavor from Colorado. Good looking piece, both pos/neg are there, but it looks like something flaked off during prep/collection and was put back on. Can anyone tell from these photos if the annotated crack looks stable, or if not, what should I use to shore it up? It won't be handled on a regular basis, but I want to make sure it's not going to fall off on its own. Sorry about the varying lighting; one photo is from the vendor's site, the other was self-shot. I assure you that they're the same specimen. The vendor has agreed to make thin
  14. hi folks, Im thinking of buying a cluster of Oviraptor from a seller who says he got these at a gem/fossil show over 10 years ago. He says he preps fossils and has extensive experience but has not finished prepping these particular eggs and won't get around to abrading them out of the matrix. I told him they are fake but he insists they are not, so I wanted to put it to the test here. thanks for your help.

    Jaw bone tooth ID help

    I have no idea the origin of this fossil. I had a couple paleontologist from a dinosaur lab look at it to no luck.
  16. Fossil skull of an extinct Sea Monster. What can you say about this piece? Is there any restoration in this piece? Where? -Zarafasaura Oceanis -Morocco -20×40×60 cm
  17. Howdy! I recently went to Post Oak creek, and ended up with more matrix than I can immediately use. Rather than let it sit unsearched, I figured it was worth a shot to post some up for trade here. Each bag has a pound of material in it, and they have proved to be very productive. I’ve found numerous ptychodus teeth, a (poorly preserved) lobster carapace, shark and fish vertebra, various bones, coprolites, and of course, lots of other shark teeth. So there’s lots of different things that can be found. I’ve got around 25-30 lbs I’d be willing to trade. I am primarily interested in verte

    Reptile Fossil ID Please

    Dear members: I wish I could say that I found this myself but I actually purchased it from an estate sale. There was no identification paperwork that came along with it but my own research online leads me to believe that it may be a Keichousaurus. I’ve examined the matrix carefully with magnification and I see enough continuation of strata from the surface down the sides and I even scraped away some matrix next to ribs to determine that this was not a fake or reproduction. So any help in confirming the identification would be appreciated. It seems to me that this is a pretty nice

    I took a small scoop of this matrix straight out of the bag.

    Tooth ID Help

    Just in case you did not read my recent post... Hope everyone is doing well. I miss being in a creek or on the beach, but all in due time. Every night I have been relaxing going through different types of matrix. Last week, in addition to looking through Bakerfield matrix, I also looked through Pungo Formation matrix from Lee Creek. I believe the these are three shark teeth are whale or basking shark teeth. All measurements are in MM. Any feedback (as always) is much appreciated!! 1. Basking shark tooth with the root!! If I am right... wow! If I am wrong.. nothing new and
  21. Found in Hays county, flaked off of a small cliff on top of a hill. Not the prettiest of pieces, but the prominent feature in the top right stuck out like a sore thumb (pun intended) and has peaked my interest which won't stop bugging me. Maybe a steinkern with a flake broken off or 2 that were pressed together and separated? Rudist? There are some small flakes of shell next to it in the matrix. Left side has some features, but needs some cleaning yet. The orange material is cemented on and cleaning that off of somewhat flaky limestone is out of my depth at the moment . Maybe

    Nodule, matrix, or whatever.

    Ku2 Hunt County, TX This is about the size of a car tire. These are typically heavy in mineral deposits on their interior with some perceived chambering. I've recovered quite a few over the past year that are very similar but none I've ever come across have had the exterior features like this one. It also carries that same orange color that I'm observing in a lot of the collected items. (Collage pic is of two others examples of the coloring referenced.) I've been pointed towards septerian nodules before with a similar submission. I've read some of the research o

    Judith River Herbivore teeth

    I posted in the fossil prep a few days ago about some Judith River matrix I got with teeth. Well now that I practiced on a damaged tooth shard I decided to start on this piece which seems to have two teeth laying on top of each other. I was hoping to get some help on what species these could be. I believe there is an ankylosaur tooth in good condition under the tooth that is more exposed. The small one is about a quarter inch and the larger underneath about 0.6 inches. this material is new to me and I have more matrix with different teeth so any other input is also helpful.
