Puesto Estancia La Costa (Miocene of Argentina)

Also known as Corriguen Aike

Where: Santa Cruz, Argentina (51.2° S, 69.1° W: paleocoordinates 52.0° S, 62.4° W)

• coordinate stated in text

• local area-level geographic resolution

When: Estancia La Costa Member (Santa Cruz Formation), Early/Lower Miocene (23.0 - 16.0 Ma)

• Dates from three levels in the lower one-third of the Santa Cruz fossiliferous beds at Monte Observación, rangebetween 16.42 Ma and 16.18 Ma and between 16.56 Ma and 16.28 Ma at Monte León. The dates are not wholly concordant but permit the assignment of the bulk of the coastal Santacrucian faunas to the late–early Miocene

• formation-level stratigraphic resolution

Environment/lithology: terrestrial; green, sandy claystone and tuffaceous, silty sandstone

• tuffaceous silty sands, andgreenish silty clays.

Size class: macrofossils
