| Incomplete drill holes produced by naticid snails are occasionally found in late Cenozoic gadid otoliths from the North Sea Basin. Among the Neogene otoliths found at Mill-Langenboom naticid drill holes are relatively common. Their occurrence is linked to strata that formed under reduced rates of sedimentation and/or that reflect non-sedimentation and erosion. The Upper Miocene–Upper Pliocene deposits at Mill-Langenboom (province of Noord-Brabant, the Netherlands) constitute a condensed sequence comprising most North Sea Basin stages of this interval from the Gramian to the end of the Pliocene, as demonstrated by index taxa amongst gadid otoliths, with a considerable hiatus between Miocene and Pliocene strata. The lag deposit at the base of the Pliocene... |

| This paper presents the integration of micropaleontological (palynology and foraminifera) and isotopic (87Sr/86Sr) analysis of a selected interval from the well 2-TG-96-RS, drilled on the onshore portion of the Pelotas Basin, Rio Grande do Sul, Brazil. A total of eight samples of the section between 140.20 and 73.50 m in depth was selected for palynological analysis, revealing diversified and abundant palynomorph associations. Species of spores, pollen grains and dinoflagellate cysts are the most common palynomorphs found. Planktic and benthic calcareous foraminifera were recovered from the lowest two levels of the section (140.20 and 134.30 m). Based on the stratigraphic range of the species of dinoflagellate cysts and sporomorphs, a span age from Late... |

| Cerca de 200 muestras de cuatro muestreadores de pistón provenientes de ambos flancos de la Cordillera Submarina Carnegie, Pacífico Ecuatorial Oriental, fueron analizadas. Cocolitofóridos fueron usados para el estudio bioestratigráfico. La presencia o ausencia de las distintas especies no concuerda con los ciclos climáticos. Las variaciones del contenido de carbonato de calcio, obedecen a mayor o menor disolución durante épocas no glaciales o glaciales respectivamente. La preservación de cocolitos y el aparente alto contenido del carbonato de calcio antes de 251.000 años sugiere poca variación de condiciones climáticos, correspondiendo a una menor disolución de material calcáreo. |

| The Aquidauana Formation is a Permo-Carboniferous sedimentary unit, widely stratigraphicaly distributed in the northwestern and northern portions of the Paraná Basin. However, little paleontological data is available from this formation, preventing accurate biostratigraphic and paleoecological interpretations. An abundant, diversified and well preserved assemblage of palynomorphs was recognized from sampling conducted in an outcrop section in Cipolândia District of Aquidauana Municipality, state of Mato Grosso do Sul, Brazil. A total of 35 indigenous palynomorph taxa was recognized, comprising 6 species of spores (related to 5 genera), 28 species of pollen grains (14 genera) and 1 species of chlorophycean algae. Monosaccate pollen grains are exceptionally... |

| Two different tectono-stratigraphic domains are recognised in the Cantabrian Mountains, Asturian-Leonese (Cantabrian Zone) and Palentian (Palentian Zone). The area under investigation belongs to the southern part of the Palentian Domain and attention is focused on the Upper Viséan to lowermost Bashkirian limestones at the village of La Lastra in northern Palencia. A new geological map of the Palentian Zone is accompanied by a more detailed map centred on La Lastra. The Barcaliente Limestone Formation (Serpukhovian to lowermost Bashkirian) occurs in the overturned limb of a recumbent anticline which constitutes the head of a south-verging major thrust unit, the Carrionas Thrust Sheet (Palentian Zone). It shows here a shallowing trend in the Serpukhovian.... |

| Upper Cretaceous and Cenozoic deposits from the Colorado and Austral basins, Argentina and the Punta del Este Basin, Uruguay contain diverse organic-walled dinoflagellate cysts, including Diconodinium lurense sp. nov. which occurs in the late Maastrichtian and Danian throughout the basins. The new species is characterized by an autophragm that is densely covered by short spines and by relatively long apical and antapical horns, and by a variable Ia to IPa archeopyle. On our evidence, the stratigraphical range of Diconodinium lurense sp. nov. is latest Maastrichtian to Danian, and is thus a useful biostratigraphical marker for the Cretaceous-Palaeogene transition in the southwest Atlantic basins. |

| Dinoflagellates are part of the marine plankton and about 200 species produce a cyst (dinocyst) during their life cycle, these organic-walled sexually-produced cysts being fossilizable in sediments for hundreds of millions of years. Over the past 40–50 years, dinocysts have led to major advances on Mesozoic-Cenozoic research, in terms of biostratigraphy and paleogeogeography. Dinocyst taxonomy has then been continuously revised, with the tabulation being the main morphological link between living dinoflagellates and fossilized cysts. Over the Quaternary, and based on the principle of uniformitarianism (i.e. species ecology did not change through time), relationships between modern assemblages and present-day environmental factors controlling their... |

| Holoplanktonic Mollusca collected from c. 60 localities in Cenozoic (Eocene-Ypresian to Miocene-Serravallian) rocks of the Aquitaine Basin (southwest France) are represented by 75 taxa: five supposed Heteropoda (Pterotracheoidea) and 70 Pteropoda (69 Thecosomata, one Gymnosomata). All Heteropoda and 19 species of the Pteropoda had to be included in open nomenclature or with a query. Twelve species of pteropods are described as new to science: Heliconoides daguini sp. nov., H. merlei sp. nov., H. pyrenaica sp. nov. and Limacina? vegrandis sp. nov. from the Ypresian; Creseis antoni sp. nov. and Vaginella gaasensis sp. nov. from the Rupelian; Clio lozoueti sp. nov. and Clio vasconiensis sp. nov. from the Chattian; Diacrolinia cluzaudi sp. nov., from the... |

| The insectivores of three assemblages from the Kargi K.Y.B. lignite mine are described. These assemblages are considered to be of Early Miocene age, intermediate between those from Inkonak and Kilçak. In Kargi 2 a shrew was found that was not yet known from Lower Miocene deposits in Anatolia. All other insectivores found were encountered in Inkonak and/or Kilçak also. Notable absentees are the talpids Theratiskos and Suleimania, a small shrew and the dimylid Turkodimylus. The two talpids and the shrew are probably Asian immigrants that appeared in Anatolia after the deposition of the Kargi lignite sequence. The absence of Turkodimylus is probably a result of the small sampling sizes. |

| This article deals with biostratigraphy, palaeoecology and biogeography of the Late Oligocene/Early Miocene insectivore faunas from Anatolia. With the exception of the much younger fauna from Keseköy, all faunas contain the same insectivore species. Keseköy contains the same genera, but mostly different species. It has been suggested that insectivores are of limited stratigraphical use due to the longevity of the taxa. This seems to hold true for the Early Miocene faunas from Anatolia. Changes in the composition of the insectivore faunas are used to infer environmental changes. A rise in the abundance of insectivores near the MP 30/MN 1 transition is believed to be indicative of a climatic amelioration. The dominance of Theratiskos in Harami and Keseköy... |

| A borehole was drilled at Rotterdam in 1955 as a demonstration during the E55 exhibition. Holoplanktonic molluscs (pteropods) were found to be present in the interval 504.5-655.0 m below rotary table (= RT). The upper sample of Middle Eocene (Lutetian) age yielded just a few unidentifiable limacinids. The section between 507.5-607.0 m, of Early Eocene (Ypresian) age, yielded poorly preserved pteropods and demonstrated that the complete interval belongs to pteropod zone 9. Apart from the most abundant species, Camptoceratops priscus, which is the index taxon of pteropod zone 9, the section yielded Heliconoides mercinensis and Limacina taylori, which are known to accompany the index species. Two further limacinid species are described as new to science, viz.... |

| ABSTRACT We review geological evidence on the origin of the modern transcontinental Amazon River, and the paleogeographic history of riverine connections among the principal sedimentary basins of northern South America through the Neogene. Data are reviewed from new geochronological datasets using radiogenic and stable isotopes, and from traditional geochronological methods, including sedimentology, structural mapping, sonic and seismic logging, and biostratigraphy. The modern Amazon River and the continental-scale Amazon drainage basin were assembled during the late Miocene and Pliocene, via some of the largest purported river capture events in Earth history. Andean sediments are first recorded in the Amazon Fan at about 10.1-9.4 Ma, with a large increase... |
