Geography

Basis of coordinate:stated in text
Geographic resolution:outcrop
Time
Period:Jurassic Epoch:Middle Jurassic
Stage:Callovian 10 m.y. bin:Jurassic 5
*Period:Late/Upper Jurassic
*International age/stage:Oxfordian - Tithonian
Key time interval:Early/Lower Callovian
Age range of interval:164.70000 - 161.20000 m.y. ago

* legacy (obsolete) database fields
Stratigraphy
Formation:Tiaojishan
Stratigraphic resolution:formation
Stratigraphy comments: Zhou et al (2013): "The Daohugou site in the Tiaojishan Formation of Inner Mongolia, China; the locality was directly dated to be 165–164 million years (Myr) old".

Older information: "possible dates [range] from Middle Jurassic to Early Cretaceous. However, published radioisotopic [both 40Ar/39Ar and zircon U-Pb] dating results span... 152 to 168 Myr" = Bathonian to Kimmeridgian (Zhang et al. 2008). Also referred to as Haifanggou Formation

"Several recent isotope datings, using both 40 Ar/39Ar and SHRIMP U-Pb methods, have indicated that the age of the (underlying) ignimbrite is between the late Middle Jurassic and early Late Jurassic, or 159-164 Ma. Therefore, the Daohugou Bed cannot be older than this age, and is not comparable to the Middle Jurassic Jiulongshan Formation" (Wang et al. 2005). Unit is older than overlying Yixian Formation. Age is therefore constrained to Callovian-Barremian
