Stratigraphy
Formation:Shanwang
Stratigraphy comments: Originally dated to Middle Miocene (Chiu et al. 1979), now MN7, Astaracian, Tunggurian.
From He et al. 2011: "40Ar/39Ar ages obtained from basalts of the Niushan and Yaoshan Formations, which underlie and overlie the Shanwang Formation, are 21.0 ± 2.5 Ma (2σ, full external error) and 17.3 ± 1.5 Ma (2σ, full external error), respectively. The 40Ar/39Ar age of the basalt in the Shanwang Formation is 17–18 Ma. Given the age constraints of the basalts of the Yaoshan and Shanwang Formations, the age of the Shanwang biota is estimated to be ca. 17 Ma, late Burdigalian of the Early Miocene,". Yu et al. 2021 support this, stating "Paleomagnetic and radio isotope dating data shows that the diatomaceous shale was deposited during Chron C5En, which places it at approximately 18.5 Ma during the Burdigalian stage of the Early Miocene, rather than in the Middle Miocene as previously thought."
