Emuha location (Devonian of China)

Also known as E

Where: Xinjiang, China (46.8° N, 86.3° E: paleocoordinates 23.6° N, 61.9° E)

• coordinate stated in text

• small collection-level geographic resolution

When: crepida to marginifera conodont zone, Hongguleleng Formation, Famennian (372.2 - 358.9 Ma)

• formation-level stratigraphic resolution

Environment/lithology: green shale and brown, yellow marl

• Maroon and green beds and the underlying marly beds. The marly beds at Emuha weather yellow-tan and, based on physical stratigraphic relations, are equivalent to the marly beds at the Boulongour Reservoir section.

Size classes: macrofossils, mesofossils

• The interval contains abundant brachiopods, bryozoans, corals, and trilobites, along with an abundant, diverse, and well-preserved echinoderm fauna.

Preservation: original calcite

Collection methods: surface (float), surface (in situ),
