  1. Past hour
  2. How hard is it to acquire an opalised fossil?

    I think it was a few years ago, but all very rare and hard to get now.
  3. Can you guys help me figure out if this Sinosaurus is genuine? It is on the ...auction site... and the seller has 4 total, they all look different from each other. I don't know enough (or anything, really) about these to determine if they're genuine or not. The description calls it a Sinohodrosaurus from a local auction, and that it has some reconstruction. I messaged the seller asking where it was collected and what the reconstructions are. I'll update if they get back to me!

    And then name a new group of dino because the articular processes run in the reverse direction.
  5. Tiny theropod tooth ID

    fantastic addition. Beautiful little tooth
  6. Tiny theropod tooth ID

    Thank you!
  7. Today
  8. Fossil ID

    I wouldn't mind seeing it. Only problem is, I work nights so it can make social interactions with "day walkers" somewhat difficult.
  9. Ait Benhaddou - Sub-Sahara - Morocco

    I like all the same pieces you do... the big bivalve, the snails, the goniatite (I agree about the prep job - it's refreshing to see things done that way when they are usually polished), and esp. the starfish plate! We should arrange some way for some of us to forward you some money to buy these things so you can snap them up when you see them, instead of having to pass them by!

    Just to be true to the genius of our forefather paleontologists, you should have attached the skull to the end of the tail.
  11. please help identify - colorful bone with chop marks

    Color is usually the result of the geochemistry of preservation. It's usually more instructive about in what formation the bone was found (sometimes it can be quite characteristic, such as with megalodon teeth), than an aid in species identification. There are of course exceptions.
  12. please help identify - colorful bone with chop marks

    Alas, after seeing the other photographs, I tend to agree with you: Not a mosasaur vert. My bad. End of a longbone?
  13. Pennsylvanian Clam?

    After seeing examples of Wilkingia, I'm leaning towards that one. I removed some more matrix, and now it's three pieces. I'll post more photos soon. I have to refer to Ohio plates often.
  14. Show us your plastic dinosaur

    I filed off molding / casting "tabs", filled joints (i.e. not skeletal joints) between pieces with paleosculp, filed down the pegs so the pieces fit together snugly (which is one of the main gripes about this model), painted and dry brushed it (the plastic pieces did not match - it looked like they mixed two batches, so some bones were grayish, and others were brownish), covered the brown plastic base with ready-mix grout to match the Hell Creek Matrix, and painted the metal support rods. I was going to attach a metal wire to the inside of the rib cage to properly space and form the ribs (the material used for this model is elastic / not very rigid and thin pieces don't conform to position), but that ended up being more complicated than I wanted to mess with.

    What modifications did you do?
  16. Mississippain Shark Tooth ID

    I came across this nice little Mississippian shark or shark-like fish tooth. The information provided by the seller is Orodus sp. St. Louis limestone Formation. Cloverdale Quarry, Cloverdale, Indiana. my question to the Paleozoic shark experts on the forum would be is this an Orodus tooth? I am far from an expert but this looks a bit like a Caseodus to me. I know Orodus teeth have several forms but this did not look like one to me. Any information or help would be awesome !!
  17. Help me identify this ground sloth...

    No harm in it...it is now part of the Forum content fabric.
  18. Any ideas?

  19. Show us your plastic dinosaur

    Whelp, I finished the 28-inch-long $17 cheapo dinosaur model I bought a few months ago. I think it looks rather respectable after a few modifications...
  20. Any ideas?

    Can you give us a pic of the other side and one straight on of the broken end?
  21. Show us your plastic dinosaur

    Oh it is a sad day indeed when you discover items from the '90s to be considered antiques!
  22. Help me identify this ground sloth...

    I posted this before exploring the site, is there any way I can remove this topic from the board? This isn't the place for it...
  23. Any ideas?

    Hello. Any ideas as to what this could be? Thanks!!
