Semi-articulated fish with ganoid scales, probably a redfieldiid, from coprolite ZPAL AbIII/3401. (A) The entire coprolite (transparent) with internal fish remains colored as follows: orange – bony part of fish scales; purple – ganoine on the exterior part of the scales (and “infilling” material in cracks); greenish yellow – lepidotrichia of the fins; white – bone and bivalve shells; red – infilled empty spaces in pelvic girdles. The dotted line indicates the inner margin of the spiral coil. (B) Ventral view of the left and right pelvic girdles of the fish with the right pelvic fin attached to the girdle. (C) Examples of two fish scales of the lateral line in exterior (top) and interior (below) views. The arrows indicate lateral line canal and pore openings. (D) Exterior view of a fragmented bivalve shell with arrows indicating surfaces of rupture. (E) Close-up of articulated fish scales and fin lepidotrichia. (F) Virtual thin section “thick slab” of fish scales and lepidotrichia (visible in the center of the image). Abbreviations: ant. – anterior; d.p. – dorsal peg; v.s. – ventral socket.
