Also known as Reef 57

Where: Guizhou, China (25.4° N, 105.7° E: paleocoordinates 16.6° N, 93.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Zhuganpo Formation, Ladinian (242.0 - 235.0 Ma)

• The Yanliujing ranges from uppermost Anisian to lower Ladinian. A Ladinian age is indicated by the reference. From Deng 2006: On the basis of a research of bivalves the coral-bearing horizon had been proven not the Yanliujing Formation but the Zhuganpo Formation.
