Stratigraphy comments: "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)

Lithology and environment
Primary lithology:"cross stratification",gray,red lithified "shale"
Lithology description: The Tiaojishan Formation is represented by intermediate extrusive and pyroclastic rocks, with intercalations of basic volcanic and sedimentary rocks (Fig . 2, ( b), ( c) ; Fig. 3), attaining a thickness of 2420 m. The Tuchengzi Formation, previously recognized as Middle Jurassic, may be Late Jurassic to Early Cretaceous in age according to new investigations of megaplants and isotope dating [14-16] . This formation conformably overlies the Middle Jurassic Tiaojishan Formation, and consists of gray-purple, purple-red shales, and sandstones with large scale cross-bedding ( Fig. 2 ( d) ) .
Environment:terrestrial indet.
