I have found these fragments of some kind of stalk (hollow tube) in a narrow organic layer between two layers of alluvial sand at a coastal site in northern Norway. We thought it might be fern at first glance, but the small cells oriented in horizontal rows are puzzling. Do you recognize what kind of organism? The age may be late Neolithic or Bronze Age. The scale bar of the photos at page 1 and 2 is 1 mm.
