Where: Guangxi, China (23.3° N, 109.3° E: paleocoordinates 5.0° N, 125.9° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Spathognathodus remscheidensis conodont zone, Beijuntang Formation, Lochkovian (419.2 - 410.8 Ma)

• "Immediately below Monograptus hercynicus - Monograptus praehercynicus zone and above the Monograptus uniformis zone." PJW: the Monograptus praehercynicus zone comes after the Monograptus uniformis, so I am putting it at the boundary.
