Also known as Jianchang
Where: Liaoning, China (40.8° N, 119.8° E: paleocoordinates 42.1° N, 123.0° E)
• coordinate based on political unit
• small collection-level geographic resolution
When: Tiaojishan Formation, Oxfordian (163.5 - 157.3 Ma)
• The Daxishan site (also known as the Daxigou site) of Liaoning was most recently dated to be 160±0.99 Ma (12-Liu et al. 2012). The Lanqi Formation, a stratigraphic equivalent of the Tiaojishan in the adjacent Beipiao area, is dated to be 160 Ma in a recent geochronological study (34-Chang et al. 2009) (more discussion on “Geological Age of Tiaojishan Formation”). The Daxishan site is of the Oxfordian age of the Late Jurassic" (Yuan et al. 2013)
