  1. I have alot of fossils with super thin matrix on them. How do i prep it manually? The rocks are limestone.
  2. While I have been out fossil hunting a bit in the Texas Summertime heat I am still having great fun with the Micro Matrix- it sure is pleasant to sit in the AC and poke about for fossils! I had some great little finds in the Mineral Wells matrix, but i am just amazed by the Bridgeport matrix. Even though it's still Pennsylvanian, it's very different from the MIneral Wells stuff! Different formations and all..... What's really neat about the Bridgeport matrix is firstly - it's bigger, typically. and secondly...it's COLORFUL! Reds and golds and purply browns and oranges. It's really lovely stuff!! Here are some of my favorites from the Jasper Creek formation. : First the Echinoid bits - I love these little "cat ghost" plates. 2 mm Most of the spines were incomplete, but I found a nice base and a nice spine, just not all one piece 7mm base and 1 cm spine A funky Echinoid plate 7 mm So many neat Crinoid fragements - arms, cup fragements, columnals, etc! All of these are aprox 5-8 mm except the first one which is a honking 1.5 cm. ) And this crazy crinoid spine that was broken and was regenerating before it died...hence the "dimple" on the end. Thanks fellow Forum Members for helping with that ID! 1 cm Love this crinoid column...I think it's my favorite. It's so Art Deco.....about 3 million years early. 1 cm Some other nice/ interesting finds Neospirifer Brachiopod 5 mm Not sure what this is...I assume a brachiopod. 5 mm Colorful Bryzoans 4 mm Bryzoan on a Crinoid 8 mm Girtycoelia sponges Each are aprox 5-8 mm Gastropods: Pseudozygopleura 4mm Possilbly a Phymataopleura? Not sure of ID 5 mm Possibly Goniasma? 5mm And then there's this thing......a bryzoan encrusting a sponge! 1 cm
  3. I hesitate to post this because I know next to nothing and don't know if it is worth posting, but I picked up what I would call a conglomerate one day on a Florida beach near Jensen Florida primarily because of a fossil tooth that was in the conglomerate. I could see a few other bits of bone as well. But I got to looking at the conglomerate with my microscope and saw what I thought were some nice small but interesting things. I suspect that the conglomerate is not very old and don't think there is likely anything much older than the tooth in the conglomerate except possibly some small shells, which I tried to photograph. I was thinking of dissolving this conglomerate but didn't want to destroy the shells, some of which were crystalized. I decided to try dissolving a smaller piece that I had which showed only what looked like bits of bone and had few if any shells. Here is the kind of thing that I saw in the big conglomerate that I've not decided if I would try to dissolve. What do you think? Does it look like anything old or interesting might be in this clump or do you think I would more likely to destroy some of the nicer things (if you think there might be any at all) by dissolving this clump? I'll post photos of some of the things that stuck out to me even though most were .1 cm or less. A few were slightly larger. And a a few a lot smaller. First the conglomerate showing the brown tooth, which is about .75 inches square. Then some of the much smaller things I thought were nice. The last is my favorite. Appears to be maybe a piece of coral or stem. What do you think? Thanks to all. Sorry if this is just waste of space.
  4. Greetings, I am a newbie with a good fossil hunting ground. I have permission to hunt on this property. My previous post regarding a Caudal Vert. didn't get much attention. I was trying to find the age because most other material is Pleistocene. I went looking for more verts in the piles. On the other side of building lot I found a large boulder that was solidified mostly of chalky limestone. Visible on 4 sides are what I suspect are duogong ribs. There are many micro fossils visible. I have been cleaning the sandy dirt away from where the fossils are. They appear to be on the brittle side. The boulder is 24" x 12" and about 150 pounds. A dental probe has allowed me to scrape away areas near the fossils but don't want to push it. I'm looking for suggestions on what you experts do with a specimen this size. Thanks to all of you for your ideas. I am a science teacher in Sarasota County. I know some of you are in my area. I would like to make contact with any local experts. Regards, Michael
  5. Lee Creek ID help

    Hi. Here are some cool finds from the past week after going through the Lee Creek matrix. I feel pretty confident in most of my IDs. Couple of them I have no idea. Thanks for any feedback! Much appreciated in advance! Enjoy the pictures. 1. I believe this is a catshark tooth - scyliorhinus 2. Tope shark - Galeorhinus 3. I have found a couple of these teeth that are identical to this heart shaped tooth. 4. Hardnose Shark - Carcharhinus macloti 5. I thought this was Dogfish Shark but the more i look at the root, i think I am wrong. 4. Is this a mouth plate from a fish? 5. I think this is going to be put in the Fish tooth pile. 6. Is this a broken tip of whale or dolphin tooth? Normally i would just assume fish tooth but it looks different than the others I have found. 7. Another one for the fish tooth pile?
  6. Fish/Skate Teeth ID Help

    Hi. Found some neat stuff in the Lee Creek Matrix today. I believe most of it is fish/skate teeth. If anyone get help with ID it would be much appreciated. Everything is 1 - 2mm. Also, Can somone explain how to get of the dirt on these teeth? I soaked them in hot water and some of it came off. They are so tiny to scrub. What would be safe to soak them in? Thank you for any feedback! I believe these two teeth are Rhynchobatus Teeth #1 #2 #3 I think this is some type of skate tooth but not sure what type #4 absolutely no clue #5 I believe this is a fish tooth
  7. Shell?

    Hi. I have no idea where to even begin with this one. Just found this in the Lee Creek matrix that I have been working through the past month. This one is 1MM. My uneducated guess is..... nevermind I have absolutely no clue! Anyone's guess would be better than mine. Thanks for any feedback. Mark
  8. Fish or Shark Tooth?

    I found these two teeth that are somewhat similiar. I was thinking more of shark tooth than fish but I am not sure. It is just over 1MM. Thanks for any feedback. Tooth#1 Tooth#2
  9. Unique Shark Tooth

    Hi. Found this crazy shaped tooth this morning going through Lee Creek matrix under a micrscope. Never saw anything like it before. Hopefully someone has seen this before. Looks to be slightly over 2MM. Thank you in advance for any feedback.
  10. I have some matrix pieces from ruck’s pit in Florida with some awesome calcite replacements And formations in the shells. I am open to all kinds of offers, including looking for other kinds of Matrix pieces, fossil fish and much more!
  11. Lee Creek Matrix Under A Microscope

    Hi. For Father's Day my kids got me an electic microscope. I have been picking through Lee Creek matrix that I purchased to get me through quarantine. I am really not familiar with smaller teeth so it would be greatly appreciated if anyone can confirm my ID. Enjoy the pics. For all the Dad's, I hope you had a great Father's day! This tooth is 2-3mm. I thought it was small tooth sand tiger but the root seems rather large. I have been all through Elasmo.com and I cannot find a match. The next 2 teeth cusps and the blade remind me of a mackerel but the root does not match a mackerel so I am kind of at a loss.
  12. Hi everyone, Does anyone know where I might buy unprocessed fossil matrix containing Theropod teeth?
  13. Hi everyone, I’m looking to trade for processed hell creek matrix. i have processed navesink fm matrix I’m willing to trade. I’m willing to trade 2 pounds of navesink fm matrix for every 1 pound of hell creek matrix I get.
  14. Hey all. Couple questions about North Sulfur River Tx. Why can I pull one gastropod that will be black (one species) and then within arms reach (another species) will be red? Both semi covered in the red matrix. Has anyone found a large complete red ammonite? I find pieces of large ammonites but always just pieces. I have found a complete Pachydiscus that is around 6 inches in diameter. That is the largest complete one I have found. Thanks for any help. Still learning this stuff.
  15. Acetone soak

    Hi all. I have a piece of matrix that has been consolidated in paraloid. How long do I soak it in acetone to dissolve the consolidation? Thank you in advance.
  16. I recently had a chance to try my hand at a few matrix pieces from Sharktooth Hill. I'm happy with how they came out, although I know I could do a better job next time. Huge shout out to @digit and @ynot for their advice and encouragement. I think the thing I appreciate about matrix pieces like these are that prepping them this way can turn a rather unremarkable tooth into something unique. Anyway, I had fun doing it and I was encouraged to post a "trip report" so here goes... Here's how they looked when I got home. Nice to find out the tooth was intact. WooHoo! I used dental tools (nice set online for <$20) and small paintbrushes to scratch away the matrix. A super soft fluffy brush I found in my wife's makeup kit (shhhh!) was great for removing loosened silt. The matrix looks wet because I was dipping a finger in water and barely touching the matrix to soften it. Not too much though because that Sharktooth Hill matrix can be really soft. When I got more experienced I started using a small paintbrush to apply the water more carefully. Oh nooooooooooo! The tooth fell out. Does that happen to anyone else? I decided that meant the tooth just wanted to be cleaned so I took the opportunity. A quick clean up and a little CA glue and we are back in business. QUESTION: How do the rest of you actually get the tooth clean? There was no way I was going to be able to wash it or use a toothbrush or anything like that. I can tell myself "I like them a little dirty" but can't help but notice that some people get them really nice and clean. Any tips? Esp. with that STH matrix.
  17. I am looking to trade small flat rate box(es) of Ordovician or Mississippian matrix for unsorted Permian Wellington f. (Waurika) or K Firesteel Creek (Hell Creek) matrix. PM me if you are interested. (or any other interesting micro faunal matrix)
  18. Looking for hell creek matrix

    Hi everyone, I was wondering if anyone knows where I could get hell creek matrix? If someone knows of a source, please pm me. Preferably macro but either would be good. Please pm me if you know someone. tia.
  19. Hi everybody I found a seller who is wanting to sell this Mosasaur matrix-specimen. Initial photo's look ok, but I would like to get your opinions on it. Can ask for detailed photos if needed. This would be my first 'major' item that I would add to my humble collection, so naturally, I'm cautious. Kind Regards Max (Belgium)
