Where: Xiyang, China (31.0° N, 88.0° E: paleocoordinates 20.8° S, 133.4° E)
• coordinate estimated from map
• small collection-level geographic resolution
When: Liangquan Formation, Pragian (410.8 - 407.6 Ma)
• Listed as Pragian
• formation-level stratigraphic resolution
Environment/lithology: offshore shelf; poorly lithified, silty shale and lithified sandstone
Size class: mesofossils
Collection methods: Sample with megabenthos selected at random(toward top); focus is biostratigraphy of Emsian, and so likely only focusing on important zone fossils (although brachiopods are listed as well, despite their status as non-guide taxa); setting as "pooled samples" since unsure whether the section listed is a composite one from this one locality

Purpose of describing collection: biostratigraphic analysis
