  2. Ordovician sponge?

    The patterns do look similar to Receptaculites or Fisherites, but not sure about the shape, which appears to be spherical, with a flat side. I'm not entirely sure it is Ordovician, my second guess is Devonian Ross Formation.
  3. Big British ammonites - tips please

    Thanks Steve! I suppose I was just slightly taken aback by just how little separation between the rock and the matrix there was! I've already dinged the matrix a few times, but I'm hoping that can be resolved with some sanding. I do have an abrader too, so I can try that on the smaller ones. Thanks again.
  4. Ordovician sponge?

    I also think it's an algae, to compare with, see my goniolina hexagona from the Kimmeridgian of France (it is in a gasteropod shell) :
  5. Ordovician sponge?

    And another paper, which mentions several species and other genera. https://www.app.pan.pl/archive/published/app38/app38-233.pdf
  6. Need help with fossil CRAB

    I think @Doctor Mud, could have an idea, at least about the family of your crab.
  7. South Sulphur River - Neylandville, TX Geology

    It is probably from Cretaceous Navarro Group 72-65 mya which is similar to rocks found at the North Sulphur River.
  8. Need help with fossil CRAB

    This specimen recently came into my possession with little information. There was a label that said "near Mangyshlak, Kazakhstan". I did some searching and I see nothing like this coming from Kazakhstan. I know there a number of crab experts on this forum so I was wondering if anyone recognizes this specimen. The concretion is like a sandstone. Looks porous. Also, it would not surprise me that the concretion was shaped into a concretions as there are chisel marks on the outside. The matrix looks soft enough to be shaped. However, I can't be sure. Any help is appreciated.
  9. I picked up this little spiral coprolite at the Tucson Gem Show a couple of weeks ago. It was collected by John Schultz in 2005 at the "old bridge site" on the South Sulphur River near Neylandville, Texas. I am trying to figure out the geology of the area, and I am coming up with Holocene Alluvium. Is anyone here familiar with the area? If so, is this correct? The reason I ask is that I have another spiral coprolite in my collection found along the same river in Hunt County, from the same gentleman's collection, that was labeled from the Taylor Marl - Cretaceous. Thanks for your help!
  10. Upper cretaceous oysters

    This is a kind of calcite crystals that form un rings.
  11. Fossil trade

    Hi, I would like to start a fossil trade with someone in Europe because out of Europe the shipping is very expensive. If you are interested,contact me by private message and send me a pic of the fossil you want to trade, I will then send you a fossil that's seems fair to trade with yours (No small scraps). Hope we can agree! Much appreciate it,Thomas
  12. Big British ammonites - tips please

    Hi.... I'm afraid theres no easy quick fix to get results in prepping but your on the right track by finding some practice pieces to work on.... The guys are right you need to practice skimming the rock off as described in detail in my fossil prep thread.... Your looking for a colour change from light grey matrix to a lighter calcite colour.... You can see this colour change below on the shell I'm currently working on and roughing out pictured below ....At this stage you could if you had one air abraid the remaining matrix off or like myself use various grades of wet n dry sand paper to clean off the remaining rock layer.... Getting closer to the fossil try cubing with a grinder and diamond cutting disc or get the Ken Mannion SQ as pictured above... brilliant tool' or a cheaper alternative you can find on ebay that would do a similar job which I used for ages before I got this... again pictured in the fossil prep thread.... Good luck.... I dont get notifications via email, anymore for some reason your lucky I just happened to of signed in.... Steve....
  13. Ordovician sponge?

    You may be right. I would have been safer saying a receptaculitid, I think. Yes, here's the link.
  14. Ordovician sponge?

    Fisherites if Ordovician, receptaculites is restricted to the Devonian I think (that’s what @piranha said I while ago I think, can you confirm?)
  15. Today
  16. Triassic footcast?

    To me it doesn't really resemble a footprint.
  17. Ordovician sponge?

    I think it's Receptaculites sp. a probable chlorophyte algae.
  18. Ordovician sponge?

    It reminds me of Ischadites, a type of algae.
  19. Coprolite?

    As stated here, location is most important information needed. I'm not seeing anything to indicate that it is a coprolite. You could try touching it to the tip of your tongue to see if it sticks. If it does not, it is doubtful.
  20. Coprolite?

    Did you find it in a fossil site or near a place known for its fossils? Looks more like a rock to me...
  21. Triassic footcast?

  22. Quick Visit to the Niobrara Chalk

    Do you have any specific (GPS...) coordinates of the site you collected at?
  23. Fossil in Tyndal stone

    maybe Cystostroma pictures from here
  24. Places to find teeth in the lowcountry?

    Are you planning to wade the edges, snorkel, or scuba. The forth quarter of 2017 I did some Edisto snorkeling. Did not have enough weight to hold me on the bottom. We found small bits and pieces.
  25. Dinosaur Eggshells, Alberta

    Article on the eggshells from Horseshoe Canyon. https://gregfunston.wordpress.com/2018/02/09/eggshell-from-the-horseshoe-canyon-formation/ @BadlandTraveller @HamptonsDoc @-Andy-
  26. Triassic footcast?

    It's the sort of thing that would have to be in a convincing series to be identified.
  27. Places to find teeth in the lowcountry?

    Thank you Brett. Trying to head that way now. Having a case of the lead syndrome this morning
