Geography
| Country: | Russian Federation | State/province: | Buryatia |
| Coordinates: | 53.3° North, 112.1° East (view map) | ||
| Paleocoordinates: | 56.0° North, 108.5° East | ||
| 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 m.y. ago |
Stratigraphy
| Formation: | Zaza | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: 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. | |||||
