I bought this specimen many years ago in a small museum in Austria. The fossil itself is a very fragile flat piece of coal, was collected locally and sold by the same paleontologist who works in the museum itself. I cleaned it by myself since it was not prepared and covered in soil fragments, the real shape of the fossil had remained hidden behind a black layer of dust. When purchasing, I was told that it probably was a bark fragment from Alethopteris, but looking at it now I have the heavy suspect that it is instead a small Lepidodendron branch (excluding all the surrounding undefined plant material). More detailed information: found on mount Königsstuhl in Nockalm, southern Austria dated 330 million years, Middle Mississippian, Carboniferous measures approximately 21,7 x 14,2 cm This additional photo can be found on my Deviantart page, (am I allowed to post this link here?)

This is what I believe to be an alethopteris in shale collected in Rennerdale, PA. About 3 inches across. It is housed in "museum" box I made with two modern fern fronds which were preserved with a special oxidization-inhibiting sealant.- 1 comment
