Geography
Country:Russian Federation State/province:Buryatia
Coordinates: 53.2° North, 112.8° East (view map)
Paleocoordinates:50.9° North, 120.1° East (Wright 2013)
Basis of coordinate:based on nearby landmark
Geographic resolution:outcrop
Time
Period: Cretaceous Epoch: Early Cretaceous
Stage: Aptian 10 m.y. bin: Cretaceous 3
Key time interval: Aptian
Age range of interval: 121.4 - 113.2 m.y. ago
Stratigraphy
Formation:Zaza
Stratigraphic resolution:group of beds
Stratigraphy comments: Correlative with Baissa locality. C. longipoda, E. trisetalis and Lycoptera all occur in the Zaza Formation indicating that this formation could be correlated with the upper Yixian Formation and the lower Jiufotang Formation in western Liaoning, which have a duration of 122.5-120 Ma. So it is possible to assign the Zaza Formation to an Aptian age. Also correlated with Barremian-Aptian based on plants and pollen.
