FIGURE 2. Shipingia hebaozhaiensis Shen in Zhang et al., 1976. A is a light micrograph, the others are SEM images. A, External mould of a left valve, holotype, NIGP 29859. B, Large sized reticulate platform on a growth band near the umbo. C, A reverse image of B, showing the large sized reticulations on a growth band near the umbo. D, External mould on growth bands in the posterior dorsal part of the carapace, showing the transition from small to moderate nodules. E, A reverse image showing the fine reticulations on growth bands in the antero-ventral part of the carapace. F, A reversal image of D, showing the transition from fine to large-sized reticulations on growth bands in the posterior dorsal part of the carapace. G, A reverse image showing the fine reticulations on a growth band in the ventral part of the carapace. H, A reverse image, showing the transition from large-sized reticulation to fine reticulations on growth bands in the middle part of the carapace. Scale bars = 1 mm in A; 20 µm in B, C, G; 40 µm in H; 50 µm in E; 100 µm in D, F.
