Fig. 2. Pleuromeialean lycophyte reproductive structures from the Upper Triassic of the "Alfie's Elbow" site, central Transantarctic Mountains. A. Articulated fragment of a strobilus. Individual sporophylls can be recognized by the longitudinal striations on the abaxial surface (compare Fig. 2B, C; see Fig. 3). B. Isolated sporophyll, abaxial surface. C. Same sporophyll as Fig. 2B, but after manual preparation, showing globose adaxial sporangium (s) beneath the sporophyll. D, E. Sporangia. F. Cluster of megaspores. G. Megaspores showing trilete marks and curvaturae (arrows). H–J. Distal faces of megaspores showing variation in surface ornamentation or preservation, including verrucate, conate, and echinate patterns. ... : 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 197, DOI: 10.4202/app.2010.0022, http://zenodo.org/record/13279913 ...
