Where: Xinjiang, China (46.6° N, 86.0° E: paleocoordinates 23.3° N, 62.0° E)

• coordinate based on political unit

• outcrop-level geographic resolution

When: Hongguleleng Formation, Famennian (372.2 - 358.9 Ma)

• member-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified limestone

• "...a few limestone beds, which yielded the fossils.." Author also lists as present lithotypes: "yellowish brown, purplish red, grayish green tuffaceous sandstone and conglomerate, siliceous siltstone." These are apparently alternating marine and continental facies.
