Figure 9. ‘Sinoeocrinus globus’ (GM-9–4–1524) with stereomic microstructure from the Kaili Formation. (a) Brachioles. (b) Close-up of a brachiole section. (c) A twisted region of a single brachiole. (d) A portion of thecal plates with stereom in adjacent plates infilled with syntaxial calcite cement. (e) Close-up of thecal plates with stereom. (f) Close-up of brachiolar plates. (g) Close-up of a single thecal plate with stereom. (h, i) Details of stereom in thecal plates. (a, b, g, h) Secondary electron images; (c–f, i) backscatter electron images. Scale bars = 4 mm (a); 400 µm (b); 600 µm (c, f); 1 mm (d, e, g); 100 µm (h, i). Abbreviations: b.s. – brachiolar stereom; c.c. – carbonate cement.
