Where: Hunan, China (28.4° N, 109.5° E: paleocoordinates 21.9° N, 146.8° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Glyptagnostus reticulatus trilobite zone, Huaqiao Formation, Furongian (497.0 - 485.4 Ma)

Dong and Knoll 1996 included the bed in the lower part of the Bitiao Formation, but following revision of stratigraphic nomenclature (Peng & Robison, 2000), the Huaqiao, Chefu, and Bitiao formations have been grouped into a single unit, the Huaqiao Formation. Paibian stage
• bed-level stratigraphic resolution
Environment/lithology: slope; lithified limestone
Size class: macrofossils
Preservation: mold/impression
