Also known as Baizai, Xundian - [Zhongyicun Mbr, Yuhucun Fm]

Where: Yunnan, China (25.6° N, 103.1° E: paleocoordinates 36.1° N, 163.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Anabarites trisulcatus - Protohertzina anabarica / Siphogonuchites triangularis - Paragloborilus subglobosus small shelly zone, Zhongyicun Member (Zhujiaqing Formation), Meishucunian to Meishucunian (530.7 - 525.5 Ma)

• LITHOSTRATIGRAPHIC RELATIONS: From the Zhongyicun Mbr of the Zhujiaqing Fm. AGE: Meischucunian stage in Feng et al (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).
