  2. Show us your plastic dinosaur

    Just to be true to the genius of our forefather paleontologists, you should have attached the skull to the end of the tail.
  3. 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.

  5. 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?
  6. 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.
  7. 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?
  9. 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 !!
  10. Help me identify this ground sloth...

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

    Absolutely
  12. 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...
  13. Any ideas?

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

    Oh it is a sad day indeed when you discover items from the '90s to be considered antiques!
  15. 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...
  16. Any ideas?

    Hello. Any ideas as to what this could be? Thanks!!
  17. New dicynodonts from Laos

    A new dicynodont-related paper is available online: Chloe Olivier, Bernard Battail, Sylvie Bourquin, Camille Rossignol, J.-Sebastien Steyer & Nour-Eddine Jalil (2019) New dicynodonts (Therapsida, Anomodontia) from near the Permo-Triassic boundary of Laos: implications for dicynodont survivorship across the Permo-Triassic mass extinction and the paleobiogeography of Southeast Asian blocks, Journal of Vertebrate Paleontology, DOI: 10.1080/02724634.2019.1584745 Dicynodon incisivum was the first dicynodont and first pre-Mesozoic tetrapod found in Laos, but has been dismissed as a nomen dubium. The description of Counillonia and Repelinosaurus makes clear that kannemeyeriforms and Dicynodon-like forms co-existed during the interval across Permian-Triassic boundary. By the way, is there a copy of the following paper available that I could skim through?
  18. Show us your plastic dinosaur

    While at an antique store today, I found these two kids’ meal dinosaur toddler toys from 1990. (Bronto Cheeseburger & Small Fry-Ceratops)
  19. Were these found in a completely non-marine exposure or did they come from a marine exposure? This is something I never have considered when searching matrix.
  20. ID Help

    Close ups
  21. Don I'm awaiting that exact answer from Dr. Wing. I'm trying to confirm with him some things that I read on the internet. When he lets me know, I'll post it. Marco Sr.
  22. ID Help

    With winter finally over we took a drive over to Lake Michigan to look along the beach. We found a many of the typical corals. I spotted this interesting looking fossil in the surf and quickly retrieved it. As I looked at it more closely and saw the details I became more unsure of what it is. I'll add some closeups in the next post. Thanks.
  23. Ait Benhaddou - Sub-Sahara - Morocco
