Country:Argentina State/province:Chubut
Coordinates: 43.4° South, 69.2° West (view map)
Paleocoordinates:41.0° South, 28.6° West
Basis of coordinate:unpublished field data
Geographic resolution:outcrop
Key time interval:Late/Upper Toarcian - Early/Lower Bajocian
Age range of interval:180.10000 - 168.40000 m.y. ago
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.
