I could really, really use some help on this one! I found this 1.5" cephalopod in the Cretaceous MT Laurel sand at the C&D Canal, Delaware City, DE (north side). There are only four cephalopods listed for this site in the Delaware guide, the straight-shelled Bacculites ovatus, Oxybelaoceras (which is heavily ribbed and doubles over on itself tightly in a U shape) and the golden bullets of Belemnitella americana. There are two other cephalopods listed for the canal zone - at different sites- in the Delaware guide, but they are both tightly-coiled.This one was loosely-coiled, probably in a spiral, and lightly ribbed all the way around. Most of the ribbing has broken off of this specimen, but you can just make out how they go all the way around at the upper left edge of the first photo. The closest thing I can find to this is a lightly-ribbed, loosely-coiled Cirroceras conradi. It is listed in the Cretaceous Fossils of New Jersey, through which all the canal formations run, but the only specimens found in NJ were in the Navesink formation. C. conradi also gets smoother on the inside of the coil, at least in the image in the book. I'm not very good at figuring out the text descriptions. The C&D Canal isn't supposed to cut through the Navesink formation, either, but it is as close as I can find. I'm thinking this might be one specimen I should not lose in a drawer, but I have no idea what it is or where to turn once I figure it out. It just isn't supposed to be there!
