Fossilized Biophotonic Nanostructures Reveal the Original Colors of 47-Million-Year-Old Moths
(A) Vertical longitudinal section through a stack of four scales; scales are fractured locally. r, resin; s, sediment. (B) Detail of multilayer nanostructure in a longitudinal section through a single scale. (C) Transverse section through a scale showing broad ridges and the concave geometry of the interridge surface and of the underlying multilayer structure. Scale bars: (A, C), 1 µm; (B), 500 nm.
