The Bahía Inglesa Formation (alternatively misspelled "Bahia") is a littoral, sedimentary, and highly fossiliferous geological formation that outcrops across the nearby coastal zones of Caldera, Chile. The unit is part of the greater Caldera Basin and was deposited in deep-shallow water, littoral paleoenvironments. It holds an exquisite fossil record in several localities (such as Cerro Ballena or Los Dedos), mostly composed of marine mammals, as well as invertebrate taxa.[1][2][3][4]
