Geography
| Country: | Thailand |
| Coordinates: | 18.5° North, 100.5° East (view map) |
| Paleocoordinates: | 13.4° North, 105.2° East |
| Basis of coordinate: | based on nearby landmark |
| Geographic resolution: | outcrop |
Time
| Period: | Cretaceous | Epoch: | Early/Lower Cretaceous |
| Key time interval: | Berriasian - Barremian | ||
| Age range of interval: | 145.00000 - 121.40000 m.y. ago |
Stratigraphy
| Formation: | Phra Wihan | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Unit ms4. These fossiliferous beds represent a short period during deposition in the Upper Triassic to Upper Jurassic Nan - Phayao Basin. The exact stratigraphic age of the fossils is unknown due to the lack of index species in the non-marine series. Ward & Bunnag (1964) suggested a Middle Jurassic age for the Phra Wihan Formation from its relative position within the succession. | |||||
