Coordinates: 36.6° North, 110.7° East (view map)
Paleocoordinates:42.3° North, 91.8° East
Basis of coordinate:based on nearby landmark
Geographic resolution:small collection
Key time interval:Ladinian - Carnian
Age range of interval:242.00000 - 228.00000 m.y. ago
Formation:Tongchuan Member:2
Stratigraphic resolution:bed
Stratigraphy comments: Member 2 of the Tongchuan Formation; Tongchuan Formation disconformably overlies the Ermaying Formation. Member II of the Tongchuan Formation has been radioisotopically dated at 238.6 ± 2.6 Ma and 234.6 ± 6.5 Ma using SHRIMP U-Pb analyses [31]. This suggests a Ladinian to Carnian age
