Shahai formation, coal series, Badaohao (Cretaceous of China)

Also known as Fuxin formation (1970-1992), Jiufotang formation (1992-1998)

Where: Liaoning, China (41.8° N, 122.0° E)

• Paleocoordinates: 41.1° N, 133.0° E (Wright 2013)

• coordinate estimated from map

When: Shahai Formation, Aptian (125.0 - 113.0 Ma)

• Since 1970 the coal series were estimated to belong to the Fuxin formation. 1992 they were counted to the Jiufotang formation. In this paper they are described as to belong to the lower part of the Shahai formation.

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; lithified, gray mudstone and lithified coal

• Alteration of gray, gray-white, gray-dark sandy mudstone and mudstone with tuff, but mudstone is dominant. Four coal layers are interbedded.
