Where: China (28.0° N, 107.0° E: paleocoordinates 7.9° N, 127.2° E)

• coordinate estimated from map

• basin-level geographic resolution

When: Hanchiatien Formation, Telychian (438.5 - 433.4 Ma)

• Except where otherwise stated, ref. 7624 uses Lower Silurian as equivalent to Llandovery, Middle Silurian as equivalent to Wenlock, and Upper Silurian as equivalent to Ludlow plus Pridoli. Formation may be Llandovery to Wenlock in age, but fauna and lithologic relationships with other units in the Yangtze region suggest late Llandovery age. Chen et al. 1995 put it in the Telychian (PJW).

• formation-level stratigraphic resolution

Environment/lithology: marine; gray, green, yellow shale and sandstone

Size class: macrofossils

Collection methods: Some overlap with PBDB collection 25811.
