Fossil (A,B; 47-million-year-old Volkeria messelensis from the Messel World Heritage site in Germany) and living (C,D; Hypolytrum nemorum) tropical forest sedge fruiting heads studied with synchrotron X-ray tomographic microscopy to non-destructively reveal internal structure, as shown by the digital longitudinal sections (B, D). With this technique we can also look at overall morphology (e.g., C, a digital rendering). Scale bars: A = 2 mm; B, C, D = 1mm
