SF-2, Fucheng Section (Cambrian of China)

Where: Shaanxi, China (32.5° N, 107.3° E: paleocoordinates 26.6° N, 163.3° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Xiannüdong Formation, Atdabanian (521.0 - 516.0 Ma)

• "Based on examination of the Shatan section, Zhou & Yuan (1980) provisionally placed the Xiannüdong Formation in the upper Qiongzhusian Stage, citing in support the presence of the basal part of the Yanwangbian Formation (with the trilobites Yiliangella, Shatania, and Pseudoredlichia), and the occurrence of the trilobites Wutingaspis, Yunnanocephalus, Malungia, and Zhenbaspis

•in the upper part of the Guojiaba Formation.

•

•Steiner et al. (2007 f. 9) put the bottom of this formation in the Qiongzhusian.

• bed-level stratigraphic resolution

Environment/lithology: packstone and ooidal limestone

• The 70m-thick lower member consists mainly of bioclastic packstones and marly limestones intercalated with oolitic limestones. It contains abundant fossils including archaeocyathans, calcified algae, phosphatic microbrachiopods, and Sphenothallus. Together with calcified algae (Girvanella, Epiphyton and Renalcis), the archaeocyathans occur in six discrete bioherm beds (Ye et al. 1996; Yuan et al. 2001).

Size classes: macrofossils, mesofossils, microfossils
