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Basis of coordinate:unpublished field data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.
