Where: Hunan, China (29.1° N, 111.0° E: paleocoordinates 20.7° N, 147.1° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution

• bed-level stratigraphic resolution
Environment/lithology: slope; lithified limestone
Size class: macrofossils
Preservation: cast, mold/impression
