Exploring the interior of cuticles and compressions of fossil plants by FIB‐SEM milling and image microscopy

We present the first study of cuticles and compressions of fossil leaves by Focused Ion Beam Scanning Electron Microscopy (FIB‐SEM). Cavities preserved inside fossil leaf compressions corresponding to substomatal chambers have been observed for the first time and several new features were identified in the cross‐section cuts. These results open a new way in the investigation of the three‐dimensional structures of both micro‐ and nanostructural features of fossil plants. Moreover, the application of the FIB‐SEM technique to both fossils and extant plant remains represent a new source of taxonomical, palaeoenvironmental and palaeoclimatic information.
