    heres another fossil identification challenge. these are some interesting fossils i found under a tree stump. they are likely glacial till, either from the Early Devonian or Silurian period strata to the north of Little Traverse Bay, Michigan. there are at least 3 gastropods and two cephalopods in this picture. can you point them out and/or identify them?

    E & F look like snails but I can't really see anything else clearly (except what looks like, but is not, a tiny squid in G :grin:)

    D is a Cephalopod. A and C are maybe cephalopods but it is very difficult to tell. E & F are gastropods. B is a rock :sly:.

    Contrary to public opinion, I am neither a cephalopod nor THAT old :wink:. Pleased to have picked out the gastropods though.

    ok, 5 replies, time for answers!

    A is a mold of the gastropod Opthamocirrus
    B is an unknown at best
    C has two Platyceras gastropod molds in it
    D is some kind of oncocerid cephalopod, possibly Phragmoceras
    E is another Platyceras
    F is some kind of whelk-like gastropod, Buchelia. i originally thought it was an ammonite.

    underside of A. appears to contain additional Platystoma gastropod


    E after some quick prep work. some shell is still present, but not much.
