Amber, a natural polymer, is fossil tree resin derived from diverse botanical sources with
varying chemical compositions. As such, all amber is susceptible to the effects of light …

Three-dimensional fossils, especially those preserving soft-part anatomy, are a rich source
of palaeontological information; they can, however, be difficult to work with. Imaging of serial …

Micro-computed tomography (micro-CT or microtomography) is a non-destructive imaging
