Also known as Fuxin formation (1970-1992), Jiufotang formation (1992-1998)
Where: Liaoning, China (41.8° N, 122.0° E: paleocoordinates 45.3° N, 122.0° E)
• 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.
