Xianfeng Settlement, 60 km from Kunming (Cambrian to of China)

Where: Yunnan, China (25.1° N, 103.0° E: paleocoordinates 37.0° N, 163.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Siphogonuchites-Paragloborilus small shelly zone, Dahai Member (Dengying Formation), Meishucunian to Meishucunian (530.7 - 521.0 Ma)

• Meishucunian, seemingly in Tommotian part. Formation given as Yuhucun, but Qian & Bengston (1989) say that should be Dengying

• member-level stratigraphic resolution

Environment/lithology: lithified, phosphatic, gray dolomite and lithified, glauconitic, cherty/siliceous dolomite

• Based on Dahai member beds at the Meishucun section, described in Qian & Bengston 1989.
• Grey, thick-bedded, phosphatic and silty dolomite intercalated with cherty and glauconitic horizons

Size classes: macrofossils, mesofossils, microfossils

Preservation: cast

Reposited in the PIN
