<p>(A) Optical microscope image of a section of barbules of a <i>Gansus yumenensis</i> feather (MGSF317) in reflected light, approximate position on the feather denoted by the yellow dot in <a href="" target="_blank">figure 1B</a>. (B) A map of infra-red absorption of the carboxylic acid C = O symmetric stretch at 1415 cm<sup>-1</sup> of the whole optical image taken in ATR mode. (C) A diagrammatic interpretation of (A) shows the separation of feather barbules (bottom) and sedimentary matrix (top) to guide the eye.</p
