“…The current sample of MiocenePliocene mysticete fossils from Langebaanweg represents balaenopterids, although unidentifiable odontocetes are also present. This association is consistent with coeval assemblages from New Zealand and Peru, perhaps suggesting that balaenopterids were dominant throughout the Southern Hemisphere during the Neogene (Dathe 1983, Bearlin 1988, Pilleri 1989, Brand et al 2004, Amiot et al 2008, Bisconti 2011). …”

Origin of the white shark Carcharodon (Lamniformes: Lamnidae) based on recalibration of the Upper Neogene Pisco Formation of Peru

et al. 2012

The taxonomic origin of the white shark, Carcharodon, is a highly debated subject. New fossil evidence presented in this study suggests that the genus is derived from the broad‐toothed ‘mako’, Carcharodon (Cosmopolitodus) hastalis, and includes the new species C. hubbelli sp. nov. – a taxon that demonstrates a transition between C. hastalis and Carcharodon carcharias. Specimens from the Pisco Formation clearly demonstrate an evolutionary mosaic of characters of both recent C. carcharias and fossil C. hastalis. Characters diagnostic to C. carcharias include the presence tooth serrations and a symmetrical first upper anterior tooth that is the largest in the tooth row, while those indicative of C. hastalis include a mesially slanted third anterior (intermediate) tooth. We also provide a recalibration of critical fossil horizons within the Pisco Formation, Peru using zircon U‐Pb dating and strontium‐ratio isotopic analysis. The recalibration of the absolute dates suggests that Carcharodon hubbelli sp. nov. is Late Miocene (6–8 Ma) in age. This research revises and elucidates lamnid shark evolution based on the calibration of the Neogene Pisco Formation.

“…Continental aridity records as well as isotopic measurements from marine vertebrate fossils invoke the existence of an “ancestral Humboldt current” during the Miocene [ Alpers and Brimhall , 1988; Amiot et al , 2008]. HCS evolution over the Cenozoic has been assessed since the late 80s with drillings off Peru (ODP Leg 112; see Summerhayes et al [1992] for a synthesis).…”

Impacts of Andean uplift on the Humboldt Current system: A climate model sensitivity study

et al. 2009

View full text Add to dashboard Cite

[1] Using both an atmospheric global circulation model and a regional oceanic model, we assess the impact of the Andes uplift on the Humboldt Current system (HCS). With three topographic scenarios for the Andes, we show that the uplift played a crucial role in shaping the lower troposphere dynamics over the Pacific Ocean and in turn affected the physical characteristics of the system. Our results show that the uplift has triggered a marked southward shift of the HCS, changing the latitudinal position of coastal upwelling areas as well as the strength of the South Pacific gyre. Our oceanic modeling experiments show that the latitudinal pattern of sea surface temperatures is dramatically modified with reduced Andes, with anomalies reaching up to 3°C. We discuss the feedbacks of these changes on South American climate as well as the potential onset of an altitudinal threshold that would have had triggered these changes.Citation: Sepulchre, P., L.
