Shanwang, Linqu County, collection Dong (Miocene of China)

Where: Shandong, China (36.6° N, 118.7° E: paleocoordinates 36.5° N, 116.3° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Shanwang Formation, Burdigalian (20.4 - 16.0 Ma)

• Paleomagnetic and radiometric evidence correlates the Shanwang Formation to subchron 5En of Chron 5. The main part of the Shanwang Formation covers 18.524 Ma to 18.056 Ma, with the Shanwang Formation as a whole covering 18.5 ma to 17.5 Ma. Recent paleontological results show that the Shanwang Formation can be correlated with the European mammalian zone MN instead of the previous MN5.

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine - large; lithified, diatomaceous, tuffaceous mudstone

• Two minor volcanic faulted basins, the Linqu and Shanwang Basins, are present in the study area. The former lies near the county town of Linqu, and the latter in the Shanwang National Geopark, east of this town. The faulted basins are the result of intense Mesozoic-Cenozoic tectonic extension and rifting; the development of these basins was closely related in time with the nearby NE-SW and NW-SE trending faults in the Yishu Fault Zone.

Size classes: macrofossils, mesofossils

Preservation: adpression

Collection methods: Repository: either Shandong Provincial Museum or the Museum of Shanwang fossils. This collection contains specimens labeled with the character "dong" followed by a two-digit number and "south"
