1. Contextualização taxonômica, tafonômica e morfométrica dos remanescentes ósseos da megamastofauna da Gruta Cuvieri (MG), um sítio paleontológico do Pleistoceno tardio / Taxonomic, taphonomic and morphometric contextualization of the megamastofauna bone remains from Cuvieri Cave (MG), a Late Pleistocene Palaeontological Site.
The limited knowledge regarding the Brazilian megafauna (due to a mainly taxonomist tradition of brazilian paleontologists) and the lack of controlled stratigraphic excavations of paleontological sites in Brazil motivated the excavations of Cuvieri Cave, Minas Gerais, using an unprecedented method of excavation in the country, based on detailed exhumation of

2. Pleistocene deposits of the region of confluence of Negro and Solimões rivers, Amazonas / Depósitos pleistocenos da região de confluência dos rios Negro e Solimões, Amazonas
Mudanças paleoclimáticas desde o Paleógeno na Amazônia são indicadas pela ocorrência de paleossolos lateríticos que limitam as principais unidades sedimentares da sucessão cretácea a pleistocena. Esses paleossolos podem ser usados como marcos estratigráficos regionais e mostram nítida correlação com as superfícies de descontinuidades definidas

3. "História ecológica da floresta de Araucária durante o Quaternário Tardio no setor sul da serra da Mantiqueira: análises sedimentológicas e palinológicas na região de Monte Verde (MG)" / "Ecological history of the Araucaria forest during the late Quaternary: sedimentological and palinological results from the Monte Verde region, Serra da Mantiqueira, Minas Gerais, Brazil"
Low annual average temperature (<18ºC), the localization in a zone of high altitude (>1500 m) and high floristic diversity, representative of the southern part of the Serra da Mantiqueira highlands, turn the Monte Verde region (city of Camanducaia, Southeast of the State of Minas Gerais), propitious for the inquiry of Late Quaternary climatic changes, the a

4. Variations in the quatolnary sedimentation of the coastal embayments of the Ubatuba Region, state of São Paulo / VARIACOES TEMPORAIS NA SIDIMENTACAO QUARTENARIA DOS EMBAIAMENTOS DA REGIAO DE UBATUBA, ESTADO DE SAO PAU-LO.
The objective of the present work is to study the characteristics of the surface bottom sediments of Ilha Grande Bay, Rio de Janeiro state, and their correlation with the modern hydrodynamic processes, as well as with the sedimentary evolution of the southeastern brazilian coastal region, since the maximum regression of the Upper Pleistocene. Ilha Grande Bay

5. A long marine history of carbon cycle modulation by orbital-climatic changes
Pacing of the marine carbon cycle by orbital forcing during the Pliocene and Pleistocene Ice Ages [past 2.5 million years (Myr)] is well known. As older deep-sea sediment records are being studied at greater temporal resolution, it is becoming clear that similar fluctuations in the marine carbon system have occurred throughout the late Mesozoic and Tert
