86m sample, Liangquan Formation (Devonian of China)

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

• Lithology interpreted from lithologic code of section; environmental interpretation based on mention of "typical pelagic sequence" and relationship to adjacent lithologies
• Silty shale occasionally interbedded with thin-bedded sandstones (or siltstones)

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
