English: Internal (a) and external (b) views of scale field from left flank. (c) Scales outlined in panel b showing median ridge on internal surface. Internal (d) and external (e) views of scale field from dorsal midline. (f) Left pectoral fin in ventral aspect showing the position of individual scales figured in panels g-l. (g) Scales that covered the humerus ventrally. (h, i) Elongate scales from leading edge. (j–l) Small scales from the ventral surface of the fin.

(n, o) Left lateral line scale in external and internal views. (p, q) Scale with reduced opacity and the canal shown in blue. Midway along the length of the scale, a pore connects fluid in the canal and the external environment. (r) Two of the preserved lateral line scales in reconstructed position showing their degree of overlap and expected orientation relative to the epidermis. In panels m, n: area of overlap with adjacent scale in the row shown in orange, area of overlap with scale in adjacent row shown in pink.
