    Very nice fish -Christian

  5. Kuanyangia pustulosa with Antennae

    Love the detail!
  6. Inoceramus Clam

    thanks for clearing that up for me.
  7. Inoceramus Clam

    Zenmaster6 yours are brachiopods. Dorsa valvel and ventral valve do not mirror each other. Line of symmetry is down through center of both shells. As seen in example 2 c+d While the two valves of my clam were not completely in line they have the symmetry as seen in example 1 A B of your diagram. You can not go by the over hang of the beak or pedicle alone. It is best to look at the entire fossil or as much of the fossil as you have. Your question is a good one.
  8. Inoceramus Clam

    I also agree it is a bivalve because the lines go around the shell rather than vertical to the back but it looks like a brachiopod. I just realized he got his bivalve from cedar creek Montana. I found the one above at cedar creek Washington.
  9. Inoceramus Clam

    Hey, So I have this shelled creature I found in a mountain which used to be an Eocene shallow ocean. The end is very non-symmetrical with the other side in the last photo. People keep telling me this is a bivalve but online it looks like a brachiopod.
  10. Inoceramus Clam

    The two valves have shifted relative to each other so that the beaks no longer meet. See another photo to see the shift:
  11. Inoceramus Clam

    Hi Zenmaster6 Hey, I don't wanna be that guy, but don't bivalves have equal symmetry on the ends, and brachiopods have one edge hanging over the other like the one in the picture? The photo is the hing line for this type of clam and is also the line of symmetry between both halves. While symmetry is not perfect it is there. Brachiopods have a different symmetry see this link below. Symmetry for brachiopods cuts both shells in half with more or less mirrored right and left sides. Here is a PDF link that gives details about Inoceramus clams and a bit about their morphology. I am using this paper because of the detialed information https://www.researchgate.net/publication/286250061 Palaeontology and biostratigraphy of the Middle-Upper Coniacian and Santonian inoceramids of the US Western Interior

  13. Isotelus "mafritzae"

    Too late. The article is in press and has been named after my cat.
  14. Isotelus "mafritzae"

    Thanks Harry! I've had a string tied around my finger for the past 10 years to remind me to do something, but forgot what it was. I'll get busy on that description right away. How does this sound: Etymology-Species named in honour of Harry Pristis, just because he asked.
  15. Isotelus "mafritzae"

    I am surprised (and a little disappointed) that Kevin @Northern Sharks didn't describe this bug back in 2010, naming it for me. It's not too late Kevin.
  16. Isotelus "mafritzae"

    This is a great fossil. You should do the research and write the paper.
  17. Kuanyangia pustulosa with Antennae

    Like these: LINK @MarcusFossils
  18. Kuanyangia pustulosa with Antennae

    Hi, you mean like this?
  19. Kuanyangia pustulosa with Antennae

    Hey Marcus, Any chance of more photos in the more traditional orientations?
  20. Kettneraspis

    Note there is a spelling error of "Emsian" as "Emsium"
  21. Kuanyangia pustulosa with Antennae

    I love when you can see the antennae and legs on a trilobite.
  22. Kuanyangia pustulosa with Antennae

    Stunning! What a beautiful specimen.
  23. Kuanyangia pustulosa with Antennae

    Very good prep!
