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.

My curiosity has gotten the best of me, so I am submitting this crushed specimen for an ID even though it may be unidentifiable. The item is roughly circular and about 15mm in diameter. It split with the shale and the two smaller pieces of shale contain most of one half; the other half is seem on the larger piece of shale that is split down the middle (see the picture with the ruler). What intreagues me most is the shell-like material. This specimen is from the Stark shale of the Kansas City group in the Pennsylvanian subsystem. Any ID help will be appreciated.

This specimen is from the Pennsylvanian subsystem, Kansas City group, and probably the Winterset member. I say probably because I collected it several years ago and I'm not sure. If it is not from Winterset, then it is from a some other nearby member in the Kansas City Group. It seems that the only arthropods in the Winterset are trilobytes, so I'm thinking that this is not arthropod, even though it has that superficial appearance. Can you folks help me identify it?

I assumed this item was a concretion. I regularly find fist-sized concretions in the Argentine member of the Kansas City group (Pennsylvanian subsystem). But looking this morning at a comment by @WhodamanHD here I wondered whether what I have is a sponge. The specimen is about 6 inches across and 4.5 inches from top to bottom. What do you think?

These items are from the Fontana Shale Member, Cherryvale Formation, of the Kansas City Group of the Pennsylvanian. I have found many of these small tubular specimens, and as you can see they vary in size. One of the items (at least) may be different from the others. The smallest specimen (directly below the 5mm mark has a groove down the back side which I have shown in the fourth picture. Other items found in this same location are brachiopods, branch bryozoan, horn coral, and crinoid pieces. My only guess for the specimens pictured is coprolites. I will appreciate any help in identifying these. Thanks, Russ First picture: second picture:

The black splotches on this rock appear fibrous and a bit like plant matter. They are soft and tar-like. They appear not only on the top and bottom surfaces of this rock, but also embedded in the sides where I broke the rock open. There are a number of brachiopods in the matrix too. The rock comes from the Pennsylvanian system, Kansas City group, but I'm unsure about the formation or member. For the locals, this was found near 1-435 and Gregory Blvd near Raytown, MO. My question is whether this is fossil plant matter preserved as something like bitumen or something else. Here are a couple of closeups:

I have found quite a number of these ranging from 1-4 mm or so. They are from the Kansas City Group of the Pennsylvanian Subsystem. I don't know the name of the strata, but for the locals, these come from the road cut about 1/4 mile west of I-49 on Route 150 near Belton, MO. I have found them in large (three to six inch) nodules. I will appreciate any help you can give me with identification? Russ
