Geography
Country: | Argentina | State/province: | Chubut |
Coordinates: | 43.4° South, 69.2° West (view map) | ||
Paleocoordinates: | 41.3° South, 28.1° West | ||
Basis of coordinate: | unpublished field data | ||
Geographic resolution: | outcrop |
Time
Period: | Jurassic | Epoch: | Early/Lower Jurassic |
Stage: | Toarcian | 10 m.y. bin: | Jurassic 3 |
Key time interval: | Middle Toarcian - Late/Upper Toarcian | ||
Age range of interval: | 182.90000 - 174.70000 m.y. ago |
Stratigraphy
Geological group: | Sierra de Olte | Formation: | Cañadón Asfalto | ||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: Usually given as Callovian, new work indicates that the Cañadón Asfalto Formation is considerably older, with dates ranging from the late Toarcian to the earliest Bathonian (Salani 2007; Cabaleri et al. 2010; Cuneo & Bowring 2010). Since the Queso Rallado locality does not represent the highest part of the formation, a Bathonian age can be exluded. |
