1. Ostracoda and foraminifera from Paleocene (Olinda well), Paraíba Basin, Brazilian Northeast
ABSTRACT Paleocene ostracods and planktonic foraminifera from the Maria Farinha Formation, Paraíba Basin, are herein presented. Eleven ostracod species were identified in the genera Cytherella Jones, Cytherelloidea Alexander, Eocytheropteron Alexander, Semicytherura Wagner, Paracosta Siddiqui, Buntonia Howe, Soudanella Apostolescu, Leguminocythereis Howe an

2. Carbonate Buildups in the Pernambuco Basin, NE Brazil
ABSTRACT The Pernambuco Basin represents one of the most prominent regions for deep water oil and gas exploration off the Brazilian coast. This study aims to identify and describe the occurrence of carbonate buildups in the offshore regions of the basin. The study was based on an analysis of a set of 143 2D time-migrated seismic sections that cover the offsh

3. Taxonomic revision of the fossil pulmonate mollusks of Itaboraí Basin (Paleocene), Brazil
Os calcários da Bacia de Itaboraí (Paleoceno Médio), Rio de Janeiro, Brasil, abrigam uma rica fauna de gastrópodes pulmonados do Paleoceno Médio, tanto terrestres quanto dulciaquícolas. No presente trabalho realiza-se uma extensiva revisão taxonômica dessa paleofauna. Duas novas espécies, Eoborus fusiforme e Gastrocopta itaboraiensis, são descritas

4. Biogeography on the early distribution of cuckoos (Aves: Cuculiformes)
Cuckoos are widely distributed, but are concentrated in the tropics, where they occupy a wide range of habitats. Both terrestrial and arboreal behaviors can be found in this group, but there is no consensus on as to whether these behaviors have arisen more than once. Moreover, the historical distribution of cuckoos is poorly understood. This paper presents a

5. Revisão taxonômica da malacofauna fóssil da Bacia de Itaboraí (Paleoceno), Rio de Janeiro / Taxonomic revision of the fossil molluscan fauna of Itaboraí Basin (Paleocene), Rio de Janeiro
As fácies calcárias da Bacia de Itaboraí, Rio de Janeiro, Brasil, são muito famosas por sua abundante fauna de mamíferos. Entretanto, Itaboraí também abriga uma rica fauna de gastrópodes pulmonados do Paleoceno Médio, tanto terrestres quanto dulciaquícolas. Contudo, os estudos lidando com essa malacofauna abrangem apenas as descrições originais d

6. Os vertebrados da Bacia da ParaÃba: CretÃceo Superior-Paleoceno, Nordeste do Brasil
The aim pourpose of this research is the study of the vertebrate fauna of ParaÃba Basin, using taxonomic, paleoecologic and paleoenvironment aspects with emphasis in the tooth analysis of reptiles and bone fishes (Enchodus), for the diagnostic characteristics that allow the taxonomic classification. It was indentified and revised taxonomic of 36 taxon, from

7. "Tectônica rúptil mesozóico-cenozóica na região da Serra dos Órgãos, RJ" / "Mesozoic-Cenozoic brittle tectonics of the Serra dos Órgãos range, RJ"
Mezosoic-Cenozoic brittle tectonics of the Serra dos Órgãos range in the Rio de Janeiro State, southeastern Brazil, was investigated using morphostructural analysis and field surveys. The study area is a sector of the Serra do Mar coastal range, with summits over 2.200 m a.s.l., and is included in the central segment of the Neoproterozoic-Cambrian Ribeira

8. Seismic interpretation of post-aptian magmatic events in the Cabo Frio high, Southeast Brazil, its genesis and its relation with pre-salt alignments / Interpretação sísmica dos eventos magmáticos pós-aptianos no alto de Cabo Frio, sudeste do Brasil, gênese e relação com os lineamentos pré-sal
The continental shelf of the Cabo Frio Area, at the southern part of the Campos Basin, shows unique features in its tectono-sedimentary evolution when compared to other areas of the Campos and Santos basins. The presence of a regular pattern of antithetic faults in the basement and in the syn-rift and the post-rift sedimentary sections, along with important

9. EvoluÃÃo da Bacia ParaÃba Durante o Maastrichtiano-paleoceno - FormaÃÃes gramame e Maria Farinha, NE do Brasil / Evolution of the ParaÃba Basin During the Maastrichtiano-paleoceno - Formations gramame and Maria Flour, NE of Brazil
This work presents new information about the evolution of the Paraiba Basin during the Maastrichtian-Paleocene times. This period is represented by Gramame and Maria Farinha formations, carbonate units which occur in this basin. The main purpose of the present work was the improvement of the existent knowledge about these units. This research has used data f

10. Trace shape and multi-attribute seismic facies analysis applied to paleocene/eocene reservoirs on deepwater Campos Basin
Este trabalho ilustra uma nova abordagem para caracterização de reservatórios usando metodologia de reconhecimento de padrão sísmico baseado em análise do componente principal, forma do sinal e classificação de multi-atributos 3D em um volume de dados sísmicos 3D. Nós desenvolvemos o fluxograma de interpretação do reservatório como se segue: 1)

12. Leaf assemblages across the Cretaceous-Tertiary boundary in the Raton Basin, New Mexico and Colorado
Analyses of leaf megafossil and dispersed leaf cuticle assemblages indicate that major ecologic disruption and high rates of extinction occurred in plant communities at the Cretaceous-Tertiary boundary in the Raton Basin. In diversity increase, the early Paleocene vegetational sequence mimics normal short-term ecologic succession, but on a far longer time sc
