Image of the Month: Ancient Amphibian Autopsy

A combination of scanning electron microscopy and synchrotron rapid-scanning X-ray fluorescence has revealed the most anatomically detailed structures of fossilized frogs to date. Fossilized melanosomes – the cellular repositories of the pigment melanin, in addition to a variety of different metal ions – proved to be the perfect biomarker.
