  abstract = {{T}he highly productive waters of the {H}umboldt {C}urrent {S}ystem ({HCS}) host a particular temperate ecosystem within the tropics, whose history is still largely unknown. {T}he {P}isco {F}ormation, deposited during {M}io-{P}liocene times in the {P}eruvian continental margin has yielded an outstanding collection of coastal-marine fossils, providing an opportunity to understand the genesis of the {HCS} ecosystem. {W}e present a comprehensive review, completed with new results, that integrates geological and paleontological data from the last 10 {M}y, especially focusing on the southern {E}ast {P}isco {B}asin ({S}acaco area). {W}e discuss the depositional settings of the {P}isco {F}ormation and integrate new {U}/{P}b radiometric ages into the chronostratigraphic framework of the {S}acaco sub-basin. {T}he last preserved {P}isco sediments at {S}acaco were deposited similar to 4.5 {M}a, while the overlying {C}aracoles {F}ormation accumulated from similar to 2.7 {M}a onwards. {W}e identified a {P}liocene angular unconformity encompassing 1.7 {M}y between these formations, associated with a regional phase of uplift. {L}ocal and regional paleoenvironmental indicators suggest that shallow settings influenced by the offshore upwelling of ventilated and warm waters prevailed until the early {P}liocene. {W}e present an extensive synthesis of the late {M}iocene-{P}leistocene vertebrate fossil record, which allows for an ecological characterization of the coastal-marine communities, an assessment of biodiversity trends, and changes in coastal-marine lineages in relation to modern {HCS} faunas. {O}ur synthesis shows that: (i) typical endemic coastal {P}isco vertebrates persisted up to similar to 4.5 {M}a, (ii) first modern {HCS} toothed cetaceans appear at similar to 7-6 {M}a, coinciding with a decline in genus diversity, and (iii) a vertebrate community closer to the current {HCS} was only reached after 2.7 {M}a. {T}he genesis of the {P}eruvian coastal ecosystem seems to be driven by a combination of stepwise transformations of the coastal geomorphology related to local tectonic pulses and by a global cooling trend leading to the modern oceanic circulation system.},
