Also known as Chubutisaurus type

Where: Chubut, Argentina (43.4° S, 68.3° W)

• Paleocoordinates: 39.6° S, 26.9° W (Wright 2013)

• coordinate stated in text

• small collection-level geographic resolution

When: Puesto La Paloma/Cerro Castaño Member (Cerro Barcino Formation), Late/Upper Aptian to Late/Upper Aptian (119.6 - 110.1 Ma)

• sometimes listed as Cerro Barcino member of Gorro Frigio Fm.

•

•Previously Bayo Overo Member. Krause et al. 2020 and Silva Nieto et al. 2017 consider the Bayo Overo member as an undifferentiated correlative of the Puesto La Paloma and Cerro Castaño members that crop out in the eastern localities of the Somuncurá-Cañadón-Asfalto basin, as in these eastern localities, the Puesto La Paloma, Cerro Castaño and Las Plumas members cannot be easily differentiated. Based on Krause et al. 2020 and Carballido et al. 2017. The contact zones between Puesto La Paloma and Cerros Castaño is approximately Aptian-Early Albian at ~118.5-110.8 Ma.
