Anatomical details of the fossil. X-ray computed microtomography projections and 3D views. (a) X-ray projection of the fossil showing the zeolite coating and the carbon-rich material. This image demonstrates that the material inside and outside the fossil is identical. (b) 3D side view of the whole insect exuvia with colored anatomical parts; the inset (bottom right) highlights cuticle hairs. (c) Frontal view of the forelegs with rostrum highlighted in blue. (d) Internal side view of the right foreleg, after numerically removing the zeolite coating. Animated images corresponding to (b), (c) and (d) are available in Supplementary Information 1.
