Figure 8—SRXTM reconstructions of Scandianthus costatus from the Late Cretaceous Åsen locality, Sweden; 1–3, 3-D cut longitudinal voltex reconstructions (transparent renderings) of small lignitized flower bud (S172368) showing inferior ovary and sepals and petals covering androecium and styles (1, 2), inner whorl of stamens closely adpressed to the two free styles (2), and stamens with short filaments and sagittate, dorsifixed anthers (1–3); section in 1 between orthoslices yz875 and 1075, section in 2 between orthoslices yz770–870 and section in 3 between yz440–560; dataset acquired using 103 objective and a 20 lm thick LAG:Ce scintillator at 10 keV (voxel size 0.74 lm); 4–9, reconstructions of mature, charcoalified specimens (S174119) with strongly ribbed inferior ovary and persistent calyx; dataset acquired using 103 objective and a 20 lm thick LAG:Ce scintillator at 10 keV (voxel size 0.65 lm); 4–6, 3-D reconstructions of flower in cut longitudinal voltex (transparent rendering) (4) and cut isosurface rendering (5, 6), showing persistent sepals (4, 5), stamens with extended filaments, but
