Text-fig. 4. Synchrotron radiation X-ray tomographic microscopy (SRXTM) images (volume renderings, a, b; orthoslices, c, d) of a shoot and leaves of Polytrichastrum incurvum HEDENÄS, BOMFLEUR et E.M.FRIIS from the Early Cretaceous Catefica mesofossil flora, Almargem Formation, Portugal. a, b: Shoot apex showing incurved leaves with distinctly incurved leaf margins. Note a section through the proximal part of a leaf (b) showing lamellae (arrow) over the costa and the unistratose leaf lamina (arrow head). c: Transverse section (orthoslice xy1440) of a shoot showing sections through the distal portions of six leaves showing the distinct lamellae (arrows). d: Transverse section (orthoslice xy2160) of a shoot showing sections through the proximal portions of several leaves showing the unistratose leaf lamina (arrow) with smooth cells. Specimen, Catefica 49-S266392 (a–d). Scale bars = 1 mm (a), 500 µm (b), 200 µm (c, d). in Fossil Mosses From The Early Cretaceous Catefica Mesofossil Flora, Portugal - A Window Into The Mesozoic History Of Bryophytes
