Where: Chile (27.0° S, 70.8° W)
• Paleocoordinates: 26.6° S, 68.9° W (Wright 2013)
• coordinate stated in text
• local area-level geographic resolution
When: Bahía Inglesa Formation, Messinian (7.2 - 5.3 Ma)
• highly articulated cetacean carcasses preserved at Cerro Ballena were rapidly deposited in a barrier-protected shoreface environment at ca. 6.1 Ma (Martinez et al 2025)
•
•the strata in Cerro Ballena were deposited at a time period in between the deposition of the ELJ and MTM horizons of the Pisco Formation. Thus, we infer a Late Miocene age (or Late Tortonian to Early Messinian stage) for the Bah ́ıa Inglesa Formation part of the section at Cerro Ballena
• group of beds-level stratigraphic resolution
Environment/lithology: lagoonal or restricted shallow subtidal; fine sandstone
•
•The assemblage at Cerro Ballena shares specific features with HAB-mediated mass strandings.
•
•lagoonal/restricted shallow subtidal, submarine canyon, upper continental slope to outer shelf
Size class: macrofossils
Preservation: original phosphate
Collection methods: surface (in situ),
