Also known as Corriguen Aike, Corriguen Kaik, Corriken Aike
Where: Santa Cruz, Argentina (51.2° S, 69.1° W: paleocoordinates 51.8° S, 63.4° W)
• coordinate stated in text
• local area-level geographic resolution
When: Estancia La Costa Member (Santa Cruz Formation), Santacrucian (17.5 - 16.3 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
Size class: macrofossils
Collected in 2003-2009
