From: Deciphering pyritization-kerogenization gradient for fish soft-tissue preservation
Thin section images and SEM of fish (Fig. 6a) with preserved carbonaceous soft-tissues. Thin sections GP/L 16 (a–c,f,g) and GP/L 17 (d,e,h–k). Dark opaque sinuous laminated, locally convolute muscle tissues (a–c), composed of alternating, differently coloured light/dark bands (d,e). Muscle tissue is composed of dark fibres (b,c; arrows). (f) Degraded soft-tissues and bones. (g) SEM micrograph of muscle fibre detail. (h,i) Muscle fibres (mf) in cross-section, depicting endomysium/perimysium-like connective tissues (ct) and muscle bundles (dashed ellipsis). (j,k) Scales are interlayered with soft-tissues (black) and calcite cement. Scale bars: (a–c,e,f,j,k)– 0.2 mm; (d)– 0.5 mm; (g)– 20 µm; (h)– 0.1 mm; (i)– 0.02 mm.
