Figure 11. Chemical analyses (indicated by white rectangles) of calcite-bearing gogiid specimens from the Kaili Formation. (a) Thecal plate of ‘S. globus’ (GM-9–4–1524) with stereom. (b) Thecal plate of ‘S. globus’ (GM-9–4–1524) infilled with calcite cement. (c) Stalk plate of S. lui (GM-9–2–3676B) with stereom. (d) Stalk plate of S. lui (GM-9–2–3676B) infilled with calcite cement. (e) Platelets of attachment structure of S. lui (GM-9–2–3676B). (f) Matrix of a S. lui-bearing slab (GM-9–2–3676B). Scale bars = 1 mm (a–d); 600 µm (e, f). See Gaines, Kennedy & Droser (2005, p. 196, fig. 5) or Skinner (2005, p. 169, fig. 1b) for methods.
