Described in a study published today in Journal of the Royal Society Interface, the feathers belong to an extinct bird, Eocoracias brachyptera, that was recovered from Germany’s Messel Pit. This wonderland of well-preserved fossils dates back to the Eocene period, which lasted from 56 to 33.9 million years ago.

Researchers could infer E. brachyptera’s blue color only because they could compare it with its modern relatives, the rollers. Tiny structures preserved in the fossilized feathers resemble…
