Cerro Ballena (Miocene to of Chile)

Where: Chile (27.0° S, 70.8° W: paleocoordinates 27.3° S, 68.8° W)

• coordinate stated in text

• local area-level geographic resolution

When: Bahia Inglesa Formation, Tortonian to Tortonian (11.6 - 5.3 Ma)

• 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

• fine to very fine-grained sandstones

Size class: macrofossils

Preservation: original phosphate

Collection methods: surface (in situ),
