    this is something i found and id'd this summer. the rock comes from the Gravel Point formation in northern Michigan and contains multiple round fossils around 1 1/2" in diameter. can anyone guess what they are?

    Well, I have no experiance with Pennsylvanian fossils other than what I've viewed and read on line, and since you posted in the Cephalopod Id forum I'll rule out gastropods and guess that they are ammonites of some sort...:hmm:

    I was going with snails :grin: but the shape does favor Kevin's avatar in miniature.

    I think they are Euomphalid Gastropods :smile:

    dingdingding! we have a winner!
    i honestly thought they were ammonites when i found them, but they didnt match any of the Devonian ammonites around here. personally i wonder if these snails lived like ammonite early in their life cycle.

    Well I am proud of my uneducated guess but it is only because every time Terri posts pictures I think look like little ammonites they turn out to be gastropods :oops:

    I know it's WAY more fun to go out & collect your own, but "The Bone Room" (boneroom.com) has some crazy ammonite fossils. They have whole, split & polished, which are beautiful, & even pyritized, which I think are intensely unique & eye-catching. It looks like most are sourced from Morocco & Madagascar, with the pyritized specimens coming from Russia. Definitely worth a look for you fossilphiles out there...

    Sutures and or septa are the way to tell. There are almost always some shown on a cephalopod fossil. :smile:
