Also known as Queso Rayado
Where: Chubut, Argentina (43.4° S, 69.2° W: paleocoordinates 41.3° S, 28.1° W)
• coordinate based on unpublished field data
• outcrop-level geographic resolution
When: Cañadón Asfalto Formation (Sierra de Olte Group), Middle Toarcian to Middle Toarcian (182.0 - 175.6 Ma)
• 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.
• bed-level stratigraphic resolution
Environment/lithology: lacustrine; cherty/siliceous mudstone
Size classes: macrofossils, mesofossils, microfossils
Collection methods: surface (float), surface (in situ), mechanical,
