    Some of the fossils collected and/or seen this year. All from the Early Triassic Sinbad Formation (or equivalent parts of the Thaynes Group).


    A small Prionitid


    A small mold of a Prionitid


    A large(ish) cast of a Prionitid


    Section of a coiled Nautiloid

    Yes, it may go on for a long time, seems the more data we collect the more questions we have, or we seem to answer fewer than we ask. :)

    Cool, I think the oddest thing to me ( as you mentioned in the old thread) is the lack of fossils, other than cephalopods, and I think you mentioned a few gastropods. Curious....:hmm:

    In spite of your toxic environment solution I wonder about the possibility of Semelparous gathering and spawning like the cuttlefish in Australia (that may be extincting as we speak). I wonder if there is a way to compare current positioning of such a mating ground with what you are finding. My daydream is that the deposits were shore line and the empty chambers washed up to the "beach" like we see with cuttlebones. Granted cuttlebones are lighter and you mentioned little water movement but the one picture brought the beach idea to mind.

    About the other fossils

    And the gastropods Here here and here

    The lack of baby ammonoids (protoconchs/ammonitellas) and the large size range of shells kinda rule out semelparity. :sad:

    Thanks for the references Kevin, curiousity appeased! :oops: I need to think a little more before posting. I've read most of this before, but will re-read. :roll:
