Reader Ant sent me a link to this photo and short article from ZME Science showing a beetle that is way, way old, with jeweled exoskeleton nicely preserved. The caption (the website is starting a “Fossil Friday” feature):
So, here’s a jewel beetle from the Messel Pit, Germany, 47 million years old. It’s fossilized in such a way that it maintains its iridescence and you can still see the contour of the exoskeleton – stunning!
