Liufengshan Hill, Section 4, Loc. 23 (Devonian of China)

Where: Guangxi, China (23.6° N, 109.7° E: paleocoordinates 1.2° N, 123.7° E)

• coordinate based on political unit

• small collection-level geographic resolution

When: Upper Member (Ertang Formation), Late/Upper Emsian (402.5 - 391.9 Ma)

• 19 m thick. [JA: originally entered as Emsian; Polygnathus inversus and P. serotinus are present in the lowest unit of the "Sipaian Stage" (probably this formation), so it is late Emsian]

• group of beds-level stratigraphic resolution

• gray medium bedded limestone intercalated with thin bedded nodular limestone.

Size class: macrofossils
