Some fossils of beetles that have been found in Messel, Germany almost appear as they did in real life. Not only are their shapes and structures perserved, but also the color of their original shells are only slightly changed. Unlike the colors we see, from light bouncing off a chemical, structural colors don't need chemicals. Meaning, that even though it's been millions of years, you can still see the colors in these beetle fossils. What other insects can do the same thing?
