An iridescent feathered dinosaur

Hot in science news today is a recently published paper from Nature about a newly discovered plumed dinosaur with iridescent feathers. In the past few years, we’ve had to rethink our conception of dinosaurs as giant lumbering lizards to nimble, gregarious, and feathered proto-birds.
What’s particularly exciting about this dinosaur, named Caihong (meaning ‘rainbow’), is the range of techniques brought to bear to reconstruct the colors it may have had. The scientists based these on electron microscope readings of imprints on rocks, comparing them with modern extant samples to determine their light absorbing properties.
