Where: Guangxi, China (24.1° N, 110.0° E: paleocoordinates 0.6° N, 123.6° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Sipai Formation, Late/Upper Emsian (402.5 - 391.9 Ma)
• [JA: originally entered as Emsian; Polygnathus inversus and P. serotinus are present in the lowest unit, so the entire formation is late Emsian]
• formation-level stratigraphic resolution
Environment/lithology: marine; lithified limestone and shale
Size class: macrofossils
Collection methods: Grab samples from various levels in the Sipai Fm.
