Since that first feathered dinosaur discovery, several other extinct feathered animals have been analysed using this method. This includes the four winged dinosaur Microraptor, and the possible early bird Anchiornis. In fact, one study on Microraptor has actually suggested that you can see iridescence from looking at the pattern of melanosomes within the fossils.
