Hello all - I hope my fellow hunters were able to avoid the tics and enjoy the unseasonably warm weather and enjoy a great opening weekend! We came away with one FULL 5 gallon bucket of mostly unopened concretions - with a possible Tully and some nice plant material among the open concretions. Would anyone care to take a stab at this one that came out of pit 11? Thanks! Patrick

I have some fossil grass-like leaves from a specimen that was associated with other Pennsylvanian fossils collected from near Middlesboro, Kentucky. The specimen is somewhat problematic for display purposes because it has a very nice mesocalamite fossil on the opposite side. The 1st and 2nd images are of the leaflike fossils with a closeup. The white spots are apparently where reactive iron sulfides have been exposed to atmospheric humidity and were oxidized to some type of iron sulfate. The grasslike leaves do not appear to have a strong central vein which might suggest that these are cordaites leaves. The 3rd image is of the very nice mesocalamite fossil on the opposite side. Suggestions would be greatly appreciated.

I'm in the process of photographing and cataloging specimens from a new site and thought some here might enjoy seeing some specimens as I go. These fossils were collected in eastern Illinois from the roof shales of the Herrin (No. 6) Coal. They are middle Pennsylvanian (Desmoinesian) in age. The Herrin (No. 6) Coal is the second to last coal member of the Carbondale Formation. For reference, the Mazon Creek biota occurs in the Francis Creek Shale Member, which overlies the first coal member of the Carbondale Formation, the Colchester (No. 2) Coal. Here's a general stratigraphic section of the Carbondale for reference. This biota has similarities to the Mazon Creek biota, but the flora especially is quite different. The fauna so far seems typical of terrestrial Pennsylvanian sites: bivalves, branchiopods, indeterminate arthropod parts, and a single shark egg. This biota is not well studied, and thus many names here are provisional pending a possible formal study. Scale bars are 1cm unless noted otherwise. Dunbarella striata Calamostachys tuberculata Alethopteris gibsonii Cyperites bicarinatus
