Where: Heilongjiang, China (49.0° N, 126.0° E: paleocoordinates 39.7° N, 54.8° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Early/Lower Emsian (409.1 - 402.5 Ma)

• "Hamada (1971) favored Early Emsian age..His discussion suggests that this is the most likely assignment based on known ranges of the genera he recognized. It is unlikely that the age will be outside the Late Siegenian-Emsian range."

• group of beds-level stratigraphic resolution

Environment/lithology: marine; green, argillaceous, calcareous sandstone and sandstone

Collection methods: "Many slabs of fossiliferous sandstone" (Hamada). Table 20 of ref. 7183 (which includes specimen counts for brachiopods), taken from table 5 of Hamada (ref. 7190). Table 20 actually lumps two of Hamada's lists. I have kept Hamada's lists separate and have added other taxa mentioned by Hamada.
