    Marshall Sandstone Formation Cephalopods

    Found a new Mississippian/early Carboniferous fossil site. Lots of mollusks. Quite a few straight shelled nautiloids and one coiled nautiloid.

    Gravel Point Formation Cephalopods

    I just thought I would post some nautiloid cephalopod fossils from the mid Devonian Gravel Point Formation of Bay View, Michigan, USA. Found them years ago but was busy trying to find fish fossils.
