Geochemistry of the Crato Member fossil fish from BL. (a) Specimen GP/2E 9014 from BL with points (P1, P2 – decayed soft-tissue area; P3 – bones; P4, P5 – matrix) analyzed in (b). (b) EDXRF results of the selected points in fossil depicted in (a). (c) Fossil GP/2E 7781 g. The dashed line indicates the approximate direction of thin section in (d). (d) Thin section (GP/L 20) of specimen in c depicting calcite cement filling vertebrae (1), vertebrae (2), and soft-tissues (3) around vertebrae. The red square delimits the area analyzed in (e). (e) Energy dispersive X-ray (EDS) maps of several elements distributed among the three main regions (1–3) in (d) Scale bars: (a)– 1 cm; (c)– 0.5 cm; (d)– 0.1 mm; (e)– 0.1 mm.
