Stratigraphy
| Formation: | Chilcatay | ||||
| Stratigraphy comments: 39Ar–40Ar dating of local ash layers constrains the age of the level where MUSM 2543 was found to an interval ranging from 19.0 to 18.02 Ma, early Burdigalian (late early Miocene; Di Celma et al. 2018; Bosio et al. 2020a). Based on 87Sr/86Sr ages obtained from samples taken in Ullujaya and Zamaca (see Bosio et al. 2020b) the age could be further restricted to 18.6–18.0 Ma. |
