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)

• dark gray argillaceous limestone.

Size class: macrofossils
