I understand that these are calamite stems. But could this be a mass of their leaves? I have included a picture of were these were found in southern Leavenworth county. (Douglas Group, Stranger formation) And associating rocks.

I collected this specimen at the Buildex Quarry on Highway 59 1 mile south of Ottawa, Franklin County, Kansas, USA, in March of 1970. It was dug up by a bulldozer while I was visiting the quarry one weekend. Stratigraphy: Pennsylvanian System, Virgilian Series, Douglas Group, Stranger Formation, Tonganoxie Sandstone Member, possibly overlaying the Upper Sibley coal. Age wise, is is Phanerozoic, Paleozoic, carboniferous, Upper Pennsylvanian, Gzhelian International. I found Calamites and other specimens at the same location the same day. Some were covered in carbonized material. Would very much appreciate having this identified, along with the reference or literature used to identify it, at least to the genus level if possible. I am preparing my collection for donation, so now must identify all this stuff that I haven't identified before! Thanks!!
