Where: Yunnan, China (24.7° N, 102.7° E: paleocoordinates 38.4° N, 163.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Zhongyicun Member (Zhujiaqing Formation), Nemakit-Daldynian (538.8 - 525.5 Ma)

• LITHOSTRATIGRAPHIC RELATIONS: From the Zhongyicun Mbr of the Yuhucun Fm (replaced by Steiner, 2007, with Zhujiaqing Fm. AGE: Meischucunian stage in Feng et al (2001); correlative of Caerfai in Conway Morris & Menge (2001); placed here in Nemakit-Daldynian according to Steiner et al. (2007) based on correlation of Zhongyicun Mbr to lower Meischucunian= Nemakit-Daldynian. STRATIGRAPHIC POSITION: From upper phosphatic bed (Feng et al., 2001) and "bed 7" (Conway Morris & Menge, 1991).
