Also known as Cañadón Tournouër, Casamayor, Punta Casamayor, Ètage Notostylopéen
Where: Chubut, Argentina (45.4° S, 67.4° W)
• Paleocoordinates: 46.2° S, 59.6° W (Wright 2013)
• coordinate based on political unit
• local area-level geographic resolution
When: Barrancan zone, Bartonian (41.3 - 38.0 Ma)
• Cifelli (1985) listed this collection as a Casamayoran locality without specifying its allocation to the Barrancan or Vacan, but the fauna is Barrancan.
•
•Pascual et al. 2002: De acuerdo con Cifelli (1985:20-21, figura 10, tabla 8), a pesar de lo escaso de la fauna, sus mayo- res afinidades son con los mamíferos de su «Sub-Age Barrrancan», la más moderna de las dos subedades (Subedad Vaquense y Subedad Barranquense) en que subdividió la SALMA Casamayorense.
•
•Woodburne et al. (2014) consider the Barrancan to be Middle Eocene (late Lutetian–Bartonian) in age.
