Shimen village, Yangshulin, Pingquan County (CNU 2010 collection) (Cretaceous of China)

Where: Hebei, China (41.0° N, 118.9° E: paleocoordinates 43.6° N, 120.5° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Jianshangou Member (Yixian Formation), Early/Lower Aptian (125.5 - 122.5 Ma)

• U-Pb dating from the Sihetun area indicates that the Yixian Formation ranges from 124.9 ± 1.7 Ma to 122.8 ± 1.6 Ma (Yang et al., 2007). Chang et al. (2017) obtained Ar/Ar ages of 125.8 ± 1.0 Ma and 126.0 ± 0.8 Ma from the Lujiatun Unit, the lowest part of the Yixian Formation, below the lacustrine shales. They infer an age of 125.22 ± 0.22 Ma for the lower part of the Jianshangou Unit, based on their date and previously published information. It is not clear if the formation is the same age elsewhere, but for now the same age is assigned.
