Geography
Country:Argentina State/province:Buenos Aires County:Rancul
Coordinates: 35.7° South, 64.7° West (view map)
Paleocoordinates:35.4° South, 63.0° West (Wright 2013)
Basis of coordinate:stated in text
Geographic resolution:outcrop
Time
Period: Neogene Epoch: Miocene
Stage: Messinian 10 m.y. bin: Cenozoic 6
Key time interval: Messinian
Age range of interval: 7.246 - 5.333 m.y. ago
Age estimate: 6.214 to 5.115 Ma (other)
Stratigraphy
Formation:Saldungaray
Stratigraphy comments: The stratotype is recognized in the lower levels of the Cerro Azul Formation in this locality

Prevosti et al. (2023): By combining our new radioisotopic dates with biochronology (Supplementary Table S6), a further refinement of the sigmodontine temporal record is now possible. Our results indicate a median age of 5.773 Ma (range 6.214 –5.115 Ma) for the Caleufú assemblage.
