Jiufotang Formation, Jehol Biota
Melanosome analysis of specimen CUGB P1202 demonstrated that contour feathers on the head, nape, and trunk possessed structural iridescence. Melanosomes were also identified in the wing flight feathers (remiges); however, their fine morphological structure was too degraded by taphonomic processes during fossilization to reconstruct the wing coloration with certainty.
