English: Vascularized lamellae of Keurbos susanae gen. et sp. nov. (holotype C1002). A, section of the trunk with the best-preserved lamellae; the morphology of upper vascularized lamellae consists of a frayed and wrinkled lateral margin (black-outlined white arrowheads); a ridge along the midline (black arrowhead) from which extend posterolaterally a series of veins that form a gently scalloped posterior margin (white arrowheads); and a robust ‘strut’ that tapers to a point approximately two-thirds along the lamella margin (grey arrowheads). The white dashed rectangle indicates the area of B, and the black dashed rectangle indicates the area of C. B, fine details of the lower vascularized lamella; note faint veins extending posterolaterally from the central dark line (white arrowheads). C, two upper vascularized lamellae and underlying lower lamella (white arrowhead). Abbreviation: lvl, lower vascularized lamella. Scale bars represent: 20 mm (A); 5 mm (B, C); 1 mm (D).
