Bazhai section [Xiangshudong Fm] (Devonian of China)

Where: Guizhou, China (26.0° N, 104.0° E: paleocoordinates 1.0° S, 116.1° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Xiangshudong Formation, Late/Upper Frasnian (379.5 - 376.1 Ma)

• STRATIGRAPHIC RELATIONS: From the Xiangshudong Fm, which unconformably overlies the Huohong Fm (Middle Devonian), and is overlain by the Daihua Fm (Upper Devonian). AGE: upper Frasnian, on the basis of microfossil biostratigraphy. STRATIGRAPHIC POSITION: Collection is representative for the entire formation.

• formation-level stratigraphic resolution

Environment/lithology: marine; lithified chert and lithified shale

• SPECIFIC LITHOLOGY: Thinly bedded siliceous rocks and muddy shales. LITHIFICATION: Lithified, on the basis of facies description and sample preparation techniques.

Size class: macrofossils

Reposited in the NIGPAS

• COLLECTOR: Presumably the authors. REPOSITORY: Institute of Geology and Palaeontology, Academia Sinica, Nanjing, China.
