English: Figure 1. Micro-CT images of Chuandianella ovata. (A,C-F) YKLP 16218. (A) Ventral view. Scale bar = 5.0 mm. (C) Endopod of 6th appendage showing endites. Scale bar = 1.6 mm. (D) Ventral view (white rectangle in A), showing details of second appendage (a2, green). Scale bar = 2.0 mm. (E) Same as D but with a2 not coloured. Scale bar = 2.0 mm. (F) Close-up view of 2nd appendages (rotated by 90 degrees with anterior to upper position), with podomeres numbered. Scale bar = 1.4 mm. (B,G) YKLP 16216. (B) Taphonomically deformed specimen, showing ventral view of the carapace and dorsal view of the soft parts (cf. Supplementary Figure 1). Scale bar = 3.8 mm. (G) Dorsal view of part of right side of the body, showing exopods (blue) and endopods (green). Scale bar = 1.4 mm. (H) YKLP 16238, left lateral view, showing endopods and exopods of trunk appendages. Scale bar = 4.9 mm. (I,J) YKLP 16239. (I) Ventral view, showing circa 20 eggs within the left valve. Scale bar = 4.3 mm. (J) Endopods of 3rd and 5th (?) appendages showing long blade-like endites each with a terminal seta. Proximally in this image two endopods overlap, giving the false impression of setae along the lateral margins of the endites. Scale bar = 3.4 mm. All panels are stereo-pairs. Abbreviations: a1, antennule; a2, second appendage; a3-a12, biramous appendages; ab1-4, abdominal segments 1 to 4; an, anus; asc, anterior sclerite; cs, caudal structure; eg, egg; en, endopod; es, eye stalk; et, endite; ex, exopod; ey, stalked eyes; lv, left valve; rv, right valve; se, seta; tp, tailpiece; tr, trunk. Italics indicate a right-side appendage.
