Geochemistry of the Crato Member fossil fish from GL. (a) Specimen GP/2E 9666 from grey limestones (GL). The approximate direction of thin section (in b) extraction is marked by dashed line. (b) Thin section (GP/L 16) of specimen in (a) showing calcite cement (1), vertebrae (2), and soft- tissues (3). (c) EDS maps of elemental distribution over areas (1–3) selected in (b). (d) Area mapped by SR-µXRF of the thin section GP/L 16. (e–g) SR-µXRF maps. (e) Ca – red, Fe – green. (f) Ca – red, Cu – blue. (g) Zn. Colour brightness is proportional to element concentration, and both map horizontal and vertical scale axes are in mm. Elemental maps of all elements (except for Zn) are in Supplementary Figure 9. Scale bars: (a)– 1.5 cm; (b)– 0.5 mm; (c)– 1 mm; (d)– 2 mm.
