Also known as SASw

Where: Peru (15.6° S, 74.7° W)

• Paleocoordinates: 15.2° S, 73.2° W (Wright 2013)

• coordinate stated in text

• local area-level geographic resolution

When: Pisco Formation, Messinian (7.2 - 5.3 Ma)

• See Muizon and de Vries (1985). Basal most Pliocene. A tuff layer from the Sacaco level, above the Sud-Sacaco level, has been dated radiometrically (K/Ar) to 3.9 Myr (de Muizon & Bellon, 1980, 1986). Ehret et al (2012) updated the age to Messinian (5.93 Sr isotopes) rather than Zanclean.

•"The Sud-Sacaco West locality is late Messinian in age, with Sr isotopes ranging from 6.15 ± 0.15 to 5.85 ± 0.15 Ma and U–Pb maximum depositional ages of 6.28 ± 0.05 Ma (MG4-25; Figs. 4D) and 6.62 ± 0.10 Ma (MG4-01; Fig. 4D)." (Ochoa et al. 2022)

• bed-level stratigraphic resolution

Environment/lithology: foreshore; diatomaceous siltstone
