Where: Shandong, China (36.5° N, 118.5° E: paleocoordinates 36.4° N, 116.3° E)

• coordinate based on nearby landmark

When: Middle Member (Shanwang Formation), Astaracian (16.0 - 11.6 Ma)

• MN6, Aragonian, Middle Miocene. There are six layers, which are grouped into 3 members. These members contain 3 fossil-bearing beds. SW2 is the richest level and is 20-30m thick.

The shore deposits consist of coarser clasolites which are gradually transferred into mudstone and shales towards the centre of the basin. Containing rich fossil diatoms, phosphate concretions and pyritic particles. (Yan et al. 1983)'
