The answers of biological communities to climatic fluctuations and to those tectonic movements which determined important environmental changes are one of the principal themes of research in modern Paleontology. The ideal conditions to evaluate the effects of these factors on mechanisms of radiation and differentiation of marine and continental communities and on big scale evolution of the ecosystems occurred in the tropical and temperate belts of American continent, since the uplift of Panama's isthmus. Due to the continuity of stratigraphic record in Neogene-Quaternary marine sedimentary basins and thanks to the rich continental vertebrate faunas of late Pleistocene and Holocene in the Andes cordillera and along the coast, in Ecuador it is possible to collect meaningful paleontologic-statigraphic evidences. With regard to the study of marine sedimentary basins, we will try to define the most significant events in relation to the final establishment of the Panamic Province and to the interpretation of those phenomena which regulated the sedimentary-tectonic evolution of the area under examination. Ad regards the study of continental basins, we will try, by means of the integration of sedimentological, geomorphologic, geochemical, Palynological and paleontological data, to elaborate a model able to give a reliable answer to the question regarding the crisis of mammal megafauna at the Pleistocene / Holocene transition. |
