Extended Data Fig. 1: Comparison of transmitted polarized light and Cathode-luminescence (CL) observation of cortical cells of T. miraclensis.
From: Ordovician marine Charophyceae and insights into land plant derivations
a, c, Transmitted polarized light micrograph, showing transverse section of axis with surrounding cortical (cor.) cells, TZ16-14-73-70 (2). b, d, CL observation of the same field of view a and b, very dull cathodoluminescence of the encrustations of the cortical cells indicates relatively good preservation and minimal alteration by contemporaneous fluids. e, Transmitted polarized light micrograph, showing a longitudinal section through an axis with parallel cortical (cor.) cells, TZ16-14-73-70 (2). f. CL observation of the area of the yellow dashed outline in (e), very dull cathodoluminescence of the encrustations of cortical cells indicates relatively good preservation and minimal alteration by contemporaneous fluids.
