A new study has revealed that the metallic rainbow sheen that is the mark of a fossilized beetle actually becomes redder over time.

To reveal the insects’ true colors, Yale University postdoctoral researcher Maria McNamara and her colleagues took tiny samples from beetle fossils dating back 15 million to 47 million years that were found in various spots in Germany and Idaho. The researchers analyzed the samples using a scanning electron microscope and a transmission electron microscope, both tools that use beams of electrons to create higher-resolution images of an object than could be produced using a light microscope.
