Where: Liaoning, China (40.9° N, 119.7° E: paleocoordinates 42.2° N, 122.8° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Tiaojishan Formation, Oxfordian (163.5 - 157.3 Ma)
• "The Tiaojishan Formation is generally regarded as Middle (Zhang & Zheng 1991; Liu et al. 2006; Cheng & Li 2007) to Upper Jurassic (Chang et al. 2009) (Late Bathonian-Early Kimmeridgian) in age, although it may date to the early Middle Jurassic (Aalenian) in Jianchang County (Davis et al. 2001). The unit has been dated using radiometric techniques at 169-152 Mya by Liu et al. (2006) and 165-156 Mya by Zhang et al. (2008)." (Lü et al. 2010, Proceedings B: supplement)
