I was going through my trilobite pygidiums and cephalons from the Winterset of the Pennsylvanian Kansas City group and I found this cephalon that seems different from the others I have. In particular, the genal spine seems curved. In the photos you can see both the internal mold and, in the other half of the split, the inside of the shell. I assume the pygidium beside it is belongs to the same creature, but I could be wrong. Any help with the ID will be appreciated. Russ

Hi Everyone, I found this specimen a while back and have been trying to identify it but have been unsuccessful. Its from a layer of shale within the Winterset Limestone, Kansas City group, Upper Pennsylvanian, Carboniferous. Scale in mm. I flaked it off a bigger piece that had bivalves in it which I'll post below. The depth of the flake is about 1/4th of an inch (6.35mm) thick. The fossil doesn’t carry through to either side of the flake. The piece at the top is the same specimen just what came apart when I cracked it. At the moment my guess is that it might be a bivalve of some sort but I can't find any that look similar. Here are some other bivalve species that were in the same section. The color difference is from me scrubbing it with a brush which removed the gray matrix. Any feedback is much appreciated as I can't find anything close.
