The locality of Skaar Ridge in the Central Transantarctic Mountains. It is at 2200 m, on top of a mountain that rises above the Antarctic icesheet, photo by Rudolph Serbet.
Transverse sections of a young Glossopteridale root (R) with its typical structure with wedges of wood producing a sucker shoot (S) with a conspicuous pith and “normal” wood cylinder. A later stage when they are separated but the two axes are still englobed within the same bark tissues (right). Scale bars = 200 µm.
Already #ancient antarctic #tree showed a clever survival trick! Root sprouting - new stems popping up from the roots after damage. These #Permian forests regenered from belowground and from roots! ▶️ 1url.cz/MJY2G
