Fertile axes and strobili of Guangdedendron micrum from Jianchuan (A–E, H–J, L, M) and Yongchuan (F, G, K) mines. A, B Part and counterpart of a once-dichotomized axis bearing linear leaves and a single strobilus. The arrow in A indicating a leafy stem enlarged in Fig. 3W. Arrow in B indicating portion enlarged in Fig. 7D. PKUB16052a, 16052b. C A strobilus without basal fertile axis preserved. Arrows 1 and 2 indicating portions enlarged in Fig. 7E,  G, respectively. Middle arrow indicating portion where carbonaceous material was peeled for maceration and displayed in Fig. 8A. PKUB16053. D, E Part and counterpart of a strobilus terminating a fertile axis. PKUB16001a, 16001b. F, G Part and counterpart of terminal strobili in pairs, with sporophylls along central strobilar axis and persistent vegetative leaves on fertile axis. PKUB21002a, 21002b. H At least eight strobili (arrows 1–8) preserved in the same direction (1 and 2, 7 and 8 possible paired, respectively). PKUB16047. I A dichotomized strobilus. PKUB21011. J Terminal strobili in pairs. PKUB16035. K A single and a pair of strobili perpendicular to the layers. L A short strobilus may partially preserved. PKUB16065. M Strobilus displaying central strobilar axis. PKUB16020a. Scale bars: A, B (5 cm), C, J, L, M (1 cm), D–I (2 cm); diameter of the coin for scale: 2 cm (K)
