| 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. |
