Description
Summary:We present a review and discussion of a palaeoclimatic model that considers that the "El Niño"-Southern Oscillation (ENSO) phenomena started in the Cenozoic period. We provide paleogeographic and paleoceanographic evidences recovered from the Pacific Ocean dating from the Eocene, Pliocene and Pleistocene. The available data indicate that the origin of El Niño could be dated to the Pliocene and the Pleistocene, and also that there were oscillations between El Niño and "La Niña". The evolutionary effects of the ENSO among the Eastern Pacific marine organisms are not yet clear, but fish remains can be useful to further study the ENSO occurrences during the Terminal Pleistocene and Early Holocene.
