| Summary: | Fig. 4. Pleuromeialean lycophyte leaf Mesenteriophyllum serratum Sixtel, 1961 from the Upper Triassic of the "Alfie's Elbow" site, central Transantarctic Mountains. A. Two overlying leaf fragments recognizable primarily by the distinct serrate appearance of the leaf margins. B. Detail of A showing serrate appearance of margins. C. Detail of leaf margin with alternating transverse ridges and furrows, and preserved cell pattern. Note longitudinal striae (s), circular holes on central leaf portion (some marked with arrows), and vertical alignment of transversely elongated epidermal cells (e) on leaf margin. D. Detail of leaf margin with cellular preservation, showing transversely elongated cells aligned in vertical rows. E. Detail of longitudinal striae on central leaf portion. F, G. Orthogonal pattern of epidermal cells in central leaf portion, visible only in places where carbonized cuticle layer is lifted off. ... : Published as part of Bomfleur, Benjamin, Krings, Michael, Taylor, Edith L. & Taylor, Thomas N., 2011, Macrofossil evidence for pleuromeialean lycophytes from the Triassic of Antarctica, pp. 195-203 in Acta Palaeontologica Polonica 56 (1) on page 199, DOI: 10.4202/app.2010.0022, http://zenodo.org/record/13279913 ... |
