FIGURE 5—Three-dimensional (1, 2, 4–6) and 2-D (3) SRXTM reconstructions of the lignitized flower Monetianthus mirus (S122015) from the Early Cretaceous Vale de Agua locality, Portugal; dataset acquired using 43 objective and a 20 lm thick YAG:Ce scintillator at 10 keV (voltex size 1.85 lm); specimen gold coated and studied by SEM prior to the SRXTM analysis; manipulation with Avizo software highlight the gold cover that has higher density than the coalified tissue; 1, 2, 3-D surface rendering of fossil in two different lateral views showing scars from perianth and androecium; 3, 3-D surface rendering of selected ovules superimposed on an 2-D orthoslice showing anatropous ovules with thin funicles directed towards the septum (laminar placentation); 4–6, 3-D reconstructions combining cut voltex (transparent rendering) and surface rendering of fossil in two different lateral views (4, 5) and in apical view (6) showing syncarpous ovary with many small ovules that do not fill the ovary cavity, section in 4 between orthoslices yz380 and 320, section in 5 between orthoslices xz720–750 and section in 6 between xy620–670. Scale bars for 1, 2, 4–6¼500 lm; for 3¼250 lm.
