Hi
Here is a deep decortication of Lepidophytes : Knorria morph, form very slender needle fascicles, the arrangement of pads to evoke a Lepidodendron leaf-cushions and very elongated fusiform type L. jaraczewskii, I tend to associate with the bark peeled this case because of the similarity of morphological characters. But it remains the purely speculative, because the two morphs were not found in association. You may notice in passing, several oblique lines in the tissues that presumably correspond to the path of a phytophagous organism.
best regards
Bruno
