Resumen
A compilation of the ciliated species found on freshwater and marine ostracods as epibiont or parasite (endobiont) has been carried out based on published records. The checklist includes the taxonomic position of each species of epibiontic and endobiontic ciliate, the species of basibiont ostracodes, the geographic zones and the bibliographic references where they were recorded. Altogether 7 suctorian, 29 peritrich, one apostome and one scuticociliatid species were listed. Two of recorded suctorian species are possible specific to marine ostracodes, whereas only one, Tokophrya sibirica to freshwater hosts. Fourteen species of peritrichs are likely specific to freshwater ostracodes, while three possible specific to marine ostracode hosts. Other suctorian and peritrich ciliate species were found on a variety of host taxa. One species of scuticociliatid was recorded as endobiont in ostracod.

Resumen
In recent decades, research on ostracodes has grown dramatically. While many aspects of the group have been investigated, this review focuses on the paleoenvironmental applications of ostracodes from marine and nonmarine environments. It is argued that while ostracodes have great potential as paleoenvironmental tools, much of that potential has not yet been fully realized because of our imperfect understanding of ostracode biology, taxonomy, systematics and ecology. Future developments will be sure to result from additional studies in these areas, and will also be effected by exchange of ideas with scientists working on related proxies. However, the flow of ideas should not be one-way; workers in other disciplines can also learn from the study of ostracodes.

Resumen
Leperditiocope ostracodes identified asSollenella? sp. were discovered in the Gilboa Formation (upper Givetian, uppermost Middle Devonian) within the continental Catskill Magnafacies of New York State. The deposits in which the ostracodes were found are meandering-fluvial facies that were part of a vast alluvial plain that sloped westward from the eroding Acadian Mountains. Hence, ostracodes colonized freshwater habitats earlier than heretofore thought. It has been widely accepted that, until now, the oldest known unequivocal occurrences of freshwater ostracodes are of Late Carboniferous age. This new discovery means that the first colonization of freshwater habitats by Ostracoda occurred approximately 60 million years earlier than previously known.

Resumen
AbstractTwenty-six genera and 34 species of early Miocene Indian shallow-marine ostracodes were examined for taxonomy and paleobiogeography. A new genus Paractinocythereis and new species Costa ponticulocarinata were described. Early Miocene Indian ostracode fauna shows strong affinity to Eocene–Miocene Eastern and Western Tethyan ostracode faunas and Miocene–Recent Indo-Pacific ostracode fauna, supporting the Hopping Hotspot Hypothesis that the Tethyan biodiversity hotspot has shifted eastward through Arabia to Indo-Australian Archipelago (IAA) together with concomitant biogeographic shifts of the Tethyan elements. The result also indicated an inverse westward distributional shift in a genus. It is important to note that Paleogene and Miocene shallow marine ostracodes from the IAA region remain poorly investigated, and more fossil ostracode data are needed to better test the Hopping Hotspot Hypothesis.UUID: http://zoobank.org/d1e29249-8c5b-49bf-a47a-5f18e1fc4426

Resumen
The shell chemistry of ostracodes is a useful indicator of past environmental conditions especially when the chemistry data are considered along with other proxy data. The complexities involved with the chemical and isotopic changes accompanying hydrologic change, solute evolution, and the autoecology of ostracodes all point to the need to exercise caution when interpreting shell chemistry. Nevertheless, the stable-isotope values and cation ratios (e.g., Mg/Ca, Sr/Ca) as well as the species assemblage of ostracodes can provide powerful tools for the reconstruction of paleoclimate and paleohydrology. In particular, the changes in Mg/Ca and Sr/Ca of well-calcified ostracodes shells record the qualitative changes in solute composition, and when the dissolved Mg/Ca remains relatively constant, the Mg/Ca in the ostracode shell is proportional to water temperature.

Resumen
An ostracode fauna is recorded from the Patti Formation (Late Cretaceous) of Vridhachalam area, Tamil Nadu. The assemblage includes Bairdia pentagonalis, B. cretacea, B. supplanata, Macrocypris limburgensis and Paracypris limburgensis, which are typical of Maestrichtian age. The ostracodes show strong affinities with those recorded from the Ariyalur and Pondicherry areas, and those described from the type-Maestrichtian of Holland. The above assemblage and the presence of distinct Paleocene ostracodes in the overlying Pondicherry Formation throw light on K/T transition in the Vridhachalam area. The paper also discusses the stratigraphic distribution and zoogeographic affinities of the ostracode fauna with equivalent formations in India and the type areas elsewhere.

Resumen
The results of a pilot study on late Arenigian ostracodes of Bornholm, Denmark, are reported. The hard thermally altered limestone was disintegrated with sodium hyposulphite, the yielded ostracode material is of satisfactory preservation. The ten identified genera include palaeocopes (Glossomorphites, Aulacopsis, Ctenentoma, Asteusloffia, Euprimites), eridostracans (Conchoprimitia), cytherelliformes (Unisulcopleura) and metacopes (Elliptocyprites, Longiscula, Microcheilinella and “Silenis”). The studied ostracode assemblage shows resemblance to that of the Central Baltoscandian Confacies Belt.

Resumen
Ostracodes are bivalved Crustacea whose fossil shells constitute the most abundant and diverse metazoan group preserved in sediment cores from deep and intermediate ocean water depths. The ecology, zoogeography, and shell chemistry of many ostracode taxa makes them useful for paleoceanographic research on topics ranging from deep ocean circulation, bottom-water temperature, ecological response to global climate change and many others. However, the application of ostracodes to the study of climate change has been hampered by a number of factors, including the misconception that they are rare or absent in deep-sea sediments and the lack of taxonomic and zoogeographic data. In recent years studies from the Atlantic, Pacific, and Arctic Oceans show that ostracodes are abundant enough for quantitative assemblage analysis and that the geochemistry of their shells can be a valuable tool for paleotemperature reconstruction. This paper presents practical guidelines for using ostracodes in investigations of climate-driven ocean variability and the ecological and evolutionary impacts of these changes.

Resumen
During examination of the large ostracode assemblage collections at the Department of Scientific and Industrial Research, Geology & Geophysics, Lower Hutt, New Zealand, a single specimen of unusual shape was encountered. So unusual is the crescentic outline and infolding of the entire shell periphery that assignment even to a phylum was difficult, and it was only upon scanning electron microscopic study that subcentral muscle scars were clearly observed and these enabled confident identification of the specimen as an ostracode. One specimen is not usually considered sufficient to propose a new taxon; however, in this case there is no doubt that this unique specimen clearly represents a new species, genus, and probably family of Ostracoda. A search for additional specimens from the type unit is underway, but has, as yet, been unsuccessful to find this rare intriguing ostracode. Unlike other unusual ostracodes described from the Southern Hemisphere such as the punciids, this specimen appears to have no similarity with Paleozoic taxa.

Resumen
Os ostracodes são microcrustáceos predominantemente bentônicos que deixaram rico registro fóssil, constituindo-se em importante ferramenta para a interpretação paleoambiental e bioestratigráfica. Estudos que tratam dos ostracodes recentes são de grande importância à Paleomicrontologia, pois muitos gêneros e até mesmo espécies do Cenozoico ainda são encontrados nos mares atuais. Diversos estudos versam sobre os Ostracoda na plataforma continental e talude superior no Brasil, mas são raras as pesquisas nas águas mais rasas do infralitoral. O principal objetivo deste estudo foi identificar e ilustrar a riqueza de espécies ao longo de uma ampla área litorânea do sul do Brasil, cuja costa é formada por numerosas pequenas praias guardadas por promontórios rochosos. Discutir aspectos relacionados à zoo- e à paleozoogeografia em especial dos elementos autóctones desta ostracofauna, além de introduzir a discussão sobre a fidelidade composicional entre associação viva e morta na área de estudo, estão entre os objetivos subsequentes.Dezoito famílias, 33 gêneros e 46 espécies foram identificados nesse estudo. A família Hemicytheridae é a mais representativa com 18 espécies, seguida por Cytheruridae com seis espécies. Duas espécies do gênero Xestoleberis Sars foram identificadas como prováveis novos táxons para Xestoleberididae. Preliminarmente, a fidelidade composicional é baixa, com maior riqueza na associação morta, bem como grande dominância e baixa riqueza na associação viva, um padrão esperado para zonas marinhas rasas como o infralitoral.
Ostracoda are microcrustaceans with predominantly benthic habit which exhibit an abundant fossil record and constitute an important tool for paleoenvironmental and biostratigraphic studies. Research about recent ostracodes are extremely relevant to Paleomicrontology since many genera and even species from Cenozoic are still found nowadays. Several studies on Ostracoda from Brazil have focused on continental shelf and upper slope. The present work aims to identify and illustrate the species richness over a broad coastal area from southern Brazil, which coast is represented by numerous small sandy beaches guarded by rock promontories. Also, discuss zoo- and paleozoogeographic aspects, mainly related to autochthonous elements of this ostracofauna, and to introduce the discussion of compositional fidelity between living and dead ostracode assemblages, are among the subsequent objectives. Eighteen families, 33 genera and 46 species were identified. The family Hemicytheridae is the most representative with 18 species followed by Cytheruridae with six species. Two Xestoleberididae species herein identified are probably new taxa. A preliminary analysis showed low compositional fidelity with richness higher in death than in living assemblages. The living assemblage showed high dominance and low richness. This pattern is common for shallow marine zones such the infralittoral.

Resumen
Les ostracodes, microcrustacés (Arthropoda), sont relativement abondants dans les archives paléontologiques. Sensibles aux variations paléoenvironnementales, la composition des assemblages et leur diversité sont d’excellents marqueurs des changements qui affectent le benthos marin néritique. Leur diversité est connue pour être fortement affectée par la crise biologique marquant la limite Permien-Trias, mais leur histoire à la fin du Permien moyen reste peu documentée.Près de 10 Ma avant la limite Permien-Trias, à la fin du Permien moyen, un important épisode d’extinction intervient, préfigurant le déclin de la biodiversité à la fin du Paléozoïque.L’étude systématique des échantillons prélevés le long des coupes de Chaotian (province du Sichuan, Chine) et de Penglaitan (province du Guangxi, Chine) a permis l’identification de 115 espèces d’ostracodes, dont 7 nouvelles. Le travail réalisé sur ces coupes constitue la toute première étude des événements de la fin du Permien moyen et du début du Permien supérieur s’appuyant sur l’observation des assemblages d’ostracodes. L’état de conservation des carapaces d’ostracode, étudié lors de ce travail, enregistre les effets de la fin d’un épisode de régression et le début d’un épisode de transgression au sommet du Permien moyen à Penglaitan. Les résultats s’avèrent en accord avec les données lithologiques et paléontologiques présentées dans la littérature, un modèle de reconstitution paléoenvironnementale basé sur les données de préservation des ostracodes est proposé.Une analyse critique de la qualité du jeu de données a permis d’évaluer l’influence des biais d’échantillonnage sur la représentativité du matériel fossile dans les études sur la paléobiodiversité et la paléoécologie. Les biais peuvent être corrigés par un traitement méthodologique approprié qui rend valide la comparaison des données de biodiversité. La richesse générique et spécifique décroît sensiblement au cours du Capitanien. Le passage du Permien moyen au Permien supérieur enregistre une augmentation de la richesse spécifique, malgré une faible diversité générique. L’ordre des Palaeocopida apparait ici affecté par une baisse de diversité générique et spécifique au Wuchiapingien inférieur.

Resumen
Ostracodes são microcrustáceos que possuem uma carapaça bivalve constituída por quitina e carbonato de cálcio, que vivem em ambientes marinhos e não-marinhos. São amplamente utilizados em estudos paleoceanográficos e paleoclimáticos, sendo bons indicadores batimétricos, de salinidade e de temperatura. Nas bacias brasileiras, os ostracodes têm larga aplicação bioestratigráfica, especialmente em intervalos não marinhos cretáceos. Por sua vez, os ostracodes marinhos têm se destacado pelos bons resultados paleoceanográficos em bacias marginais, entre elas a Bacia de Pelotas. Este trabalho propõe novas espécies eomiocênicas da família Cytherellidae e do gênero Actinocythereis. A partir do estudo taxonômico discutem-se implicações paleozoogeográficas de eventos como o estabelecimento da Corrente Circumpolar Antártica e da Corrente das Malvinas, cuja ação influenciou a dispersão dos ostracodes ora registrados na Bacia de Pelotas. A partir da análise do intervalo testemunhado 1300 m-1318 m do poço offshore 2-RSS-1 coletado pela Petrobras na década de 1970, são registradas cinco espécies da família Cytherellidae, duas das quais aqui descritas, como segue: Inversacytherella atlantica sp. nov., Cytherella pelotensis sp. nov., Cytherella sp. 1, Cytherella sp. 2 e Grammcythella? sp. É também proposta Actinocythereis imbeensis sp. nov., a qual constitui a segunda espécie descrita para o gênero no Brasil. São ainda registradas, Krithe coimbrai, Krithe gnoma e Henryhowella kempfi, atribuídas em trabalhos anteriores ao estabelecimento de massas de água frias na costa Sul-Brasileira. As ocorrências de Inversacytherella e Grammcythella, por sua vez, constituem evidências para o intercâmbio faunístico entre a América e a Oceania decorrentes de mudanças hidrológicas no Oceano Austral ao longo do Neogeno. O Apêndice 1 apresenta a lista e a documentação fotográfica das demais espécies registradas.
Ostracods are microcrustaceans with a bivalve carapace composed by chitin and calcium carbonate, living in both marine and non-marine environments. They are broadly used in paleoceanographic and paleoclimatic studies as indicators of bathymetry, salinity and temperature. In the Brazilian sedimentary basins the ostracodes have biostratigraphic importance, mainly in Cretaceous non-marine sections. The marine species, on the other hand, supply good paleoceanographyc data in marginal basins, including Pelotas Basin. In this work new Early Miocene species of the family Cytherellidae and the of genus Actinocythereis are proposed. Based on this taxonomic study some paleozoogeographic remarks are made, linking to the inception of the Antarctic Circumpolar Current and the Malvinas Current, to the dispersal of the ostracodes recorded in the Pelotas Basin. From the analysis of the core section 1300 m-1318 m of the offshore well 2-RSS-1 drilled by Petrobras in the 1970 decade, five species of cytherellids are recorded, two of them herein described, as follows: Inversacytherella atlantica sp. nov., Cytherella pelotensis sp. nov., Cytherella sp. 1, Cytherella sp. 2 and Grammcythella? sp. It is also proposed Actinocythereis imbeensis sp. nov., which constitutes the second species described for the genus in Brazil. Moreover, Krithe coimbrai, Krithe gnoma and Henryhowella kempfi, assigned in previous studies to the inception of cool water masses in Southern Brazilian coast, are recorded. The presence of Inversacytherella and Grammcythella, supply additional evidence for the faunal interchange between America and Oceania influenced by hydrological events in Southern Ocean along the Neogene. The Appendix 1 features the list and photographic documentation of other species registered.

O presente trabalho consiste no estudo taxonômico dos ostracodes marinhos da bacia de Pelotas e os respectivos aspectos paleoecológicos da assembléia no intervalo Cretáceo e Cretáceo – Paleógeno Inferior. Foram analisadas 479 amostras de calha, provenientes dos cinco poços 1-RSS-2, 1-RSS-3, 2-RSS-1, 1-SCS-3B e 1-SCS-2. A fauna registrada totalizou 98 espécimes, distribuídos em nove famílias, 21 gêneros, 34 espécies. Dois gêneros e duas espécies foram mantidos como táxons indeterminados. As espécies identificadas foram: Cytherella cf. C. araucana Bertels, 1974; Cytherelloidea spirocostata Bertels, 1973; Bairdoppilata triangulata Edwards, 1944; Actinocythereis indígena Bertels, 1969; Brachycythere gr. sapucariensis Krömmelbein, 1964; Wichmannella araucana Bertels, 1969 e Wichmannella meridionalis Bertels, 1969. Os gêneros mais diversificados foram Cytherella e Paracypris com sete e quatro espécies, respectivamente. O intervalo Turoniano foi o mais abundante, com a significativa presença dos gêneros Brachycythere e Cytherella . A família mais abundante foi a Trachyleberididae, com oito gêneros e 12 espécies, seguida da família Cytherellidae com dois gêneros e oito espécies. A passagem do limite Cretáceo – Paleógeno Inferior (K– Pg) na bacia de Pelotas foi marcada por uma mudança faunística com o desaparecimento dos gêneros, therelloidea, Argilloecia, Cythereis, Brachycythere, Pondoina e Rostrocytheridea, e o aparecimento de Neonesidea, Bairdoppilata, Ambocythere, Buntonia, Langiella?, Trachyleberis e Krithe . A associação dos ostracodes cretácicos na bacia de Pelotas sugere um ambiente marinho nerítico com águas quentes.
The taxonomic study of marine ostracods from Pelotas Basin and the respectives paleoecological assemblages aspects in the Cretaceous and Cretaceous – Lower Paleogene interval were studied. 479 cutting samples from wells 1-RSS-2, 1-RSS-3, 2-RSS-1, 1-SCS-3B e 1-SCS-2 were analized. 98 specimes belonging to 9 families, 21 genera and 34 species. 2 genera and 2 species were supported as undetermined taxon. The species identified were: Cytherella cf. C. araucana Bertels, 1974; Cytherelloidea spirocostata Bertels, 1973; Bairdoppilata triangulata Edwards, 1944; Actinocythereis indígena Bertels, 1969; Brachycythere gr. sapucariensis Krömmelbein, 1964; ichmannella araucana Bertels, 1969 and Wichmannella meridionalis Bertels, 1969. The most diversified genera were Cytherella and Paracypris with 7 and 4 species, respectively. The Turonian was the most ostracodes-rich interval with significant presence of the genera Brachycythere and Cytherella. The most abundant families were Trachyleberididae and Cyther ellidae with 2 genera and 8 species. The K – Pg boundary in the Pelotas basin is marked by a faunal change which disappearance the genera Cytherelloidea, Argilloecia, Cythereis, Brachycythere, Pondoina and Rostrocytheridea, and the first occurrence of Neonesidea, Bairdoppilata, Ambocythere Buntonia, Langiella?, Trachyleberis and Krithe. The Cretaceous ostracods association in Pelotas Basin sugest a neritic marin e environment with warm water temperatures.

Resumen
Os estudos com ostracodes recentes e sub-recentes da plataforma continental do Brasil têmse concentrado, até o momento, principalmente nas plataformas equatorial e sul/sudeste. A região leste/nordeste, localizada entre estas duas áreas, aqui considerada como a área entre o Cabo de São Roque (RN) e Cabo Frio (RJ), não foi devidamente estudada, apresentando diversas lacunas do ponto de vista taxonômico e zoogeográfico. Visando suprir esta carência, o presente trabalho tem por objetivo o estudo da taxonomia dos ostracodes das plataformas leste e nordeste do Brasil, buscando a integração destas informações à compreensão da sua origem e distribuição zoogeográfica. O material de estudo incluiu 102 amostras sedimentológicas, coletadas por amostradores tipo Phipps ou Van Veen, provenientes do projeto REMAC (Reconhecimento Global da Margem Continental), tratos 4 e 7, em profundidades que variaram de 12 a 110 m. Os ostracodes recuperados das amostras foram acondicionados em lâminas de células múltiplas através das técnicas usuais para a preparação e o estudo de carapaças e valvas de ostracodes. Foram reconhecidas 128 espécies não se descartando a possibilidade de espécies novas. A área de estudo é caracterizada por possuir 34% de espécies típicas de águas temperadas, 42% de águas quentes e 5% de espécies euritérmicas. As 19% restantes não puderam ser avaliadas por apresentarem baixa ocorrência. A comparação da distribuição da fauna de águas temperadas com a de águas quentes permitiu a identificação plena dos limites da zona de transição proposta por Coimbra & Ornellas (1989) e modificada por Coimbra et al. (1995). O levantamento total da fauna da porção setentrional da plataforma continental brasileira (entre o Cabo Orange e Cabo Frio) reconheceu 213 espécies, sendo 32% endêmicas. A análise da distribuição da ostracofauna permitiu o reconhecimento de cinco padrões de distribuição da fauna, todos aparentemente limitados por fatores ambientais. Baseado no grau de endemismo, na distribuição da fauna e nas características ambientais da área de estudo, foi proposta uma nova província zoogeográfica, a Província Brasileira, cujo limite sul está em torno das latitudes 15º/16ºS. O limite norte continua em aberto devido à inexistência de trabalhos para Ostracoda na região situada entre a Guiana Francesa e Guiana. Os representantes fósseis da Província Brasileira contam com espécies que ocorrem desde o Terciário. A ostracofauna não endêmica provavelmente teve seu sucesso de dispersão facilitado pelas variações eustáticas que ocorreram ao longo do Neógeno e Quaternário. A presença de massas d’água mais quentes é a característica que melhor explica a distribuição atual dos ostracodes marinhos rasos da porção setentrional da plataforma continental brasileira.
The studies concerning Recent and Sub-Recent ostracodes from the Brazilian continental shelf have been so far devoted mainly to the Equatorial and to the South/Southeast shelves. The region between these two shelves, consisting of the area between Cabo de São Roque (RN) and Cabo Frio (RJ), has not been appropriately studied and displays several gaps in Ostracoda taxonomy and zoogeography. In order to improve these deficiencies, the present study approaches the taxonomy of ostracodes form the East and the Northeast Brazilian shelves, aiming at the understanding of its origin and zoogeographical distribution. The 102 samples on which this study is based on were collected by Phillips and Van Veen grabs samplers from Remac Project (legs 4 and 7), at depths that vary from 12 m to 110 m. One hundred twenty-eigth species have been identified, some of which may be new. 34% of the species found in the study area are typical of temperate water, 42% of warm water and 5% are eurythermal. The remaining 13% of the species could not be evaluated due to insufficient occurrence. The comparison of the distribution of the temperate water fauna with the warm water fauna allowed the full identification of the limits of the transition area proposed by Coimbra & Ornellas (1989) and modified by Coimbra et al. (1995). The complete review of the fauna of the northern portion of the Brazilian Continental Shelf from Cabo Orange (AM) to Cabo Frio (RJ) recognized 213 species, 32% of which are endemic. The analysis of the distribution of the ostracode fauna allowed the identification of five distribution patterns, all of which are apparently limited by ambiental factors. A new zoogeographical province (the Brazilian Province) has been proposed. Its southern limit is located in the 15º/16º S latitude. The northern limit remains indeterminate, due to the inexistence of ostracode studies in the region from French Guyana to Guyana. Fossil representatives for the Brazilian Province display specimens that are as old as the Tertiary. The non-endemic ostracode fauna probably has its dispersion success rendered easier by the sea-level fluctuations that occurred in the Neogene and Quaternary. The presence of warmer water masses is the factor that more appropriately explains the present distribution of shallow marine ostracodes in the northern portion of the Brazilian continental shelf.

Resumen
O município de Bonito e arredores em Mato Grosso do Sul apresentam atrações turísticas relacionadas a diversos tipos de depósitos carbonáticos quaternários, que formam cachoeiras, barragens naturais e tornam as águas de turbidez quase nula. A área está inserida no Parque Nacional da Serra da Bodoquena e na Reserva da Biosfera do Pantanal (UNESCO). As tufas calcárias são rochas porosas formadas pela precipitação do carbonato de cálcio em água doce e podem conter diversos tipos de fósseis. Apresentam-se sob a forma de cachoeiras, barragens e sedimentos lacustres que formam depósitos micríticos inconsolidados, descritos dentro da Formação Xaraiés. Os micritos são extensos e relativamente espessos em toda a região. Contudo, a maior parte das ocorrências está intemperizada, parcialmente erodida e distribuída em áreas limitadas. O presente estudo foca a caracterização paleontológica, granulométrica e geoquímica (elementos maiores, menores, traços e isótopos de carbono e oxigênio), através de levantamento de detalhe dos micritos da área da Mineração Calcário Xaraés, em Bonito (MS). As amostras foram obtidas por furo de trado, coleta de amostras superficiais e de bloco decimétrico orientado para estudo tafonômico, complementado com investigação de campo e amostragem de algumas áreas na Serra da Bodoquena, Pantanal e Corumbá. Os micritos da Mineração Calcário Xaraés, são depósitos lacustres e podem ser descritos em três eventos: 1: base afossilífera, oncólitos, argilominerais e dados isotópicos marcam um período de maior umidade; 2: ostracodes, algas caráceas e gastrópodes fósseis que colonizaram este estágio e a baixa variação dos dados isotópicos sugerem um período estável; 3: gastrópodes de água doce resistentes a ressecamento colonizaram esta etapa, em associação com os dados isotópicos sugerem processos alternados de evaporação e umidade. O topo da seção estudada é marcada por evaporação total da água do lago, morte em massa do gastrópode Biomphalaria e instalação do gastrópode Idiopyrgus. A ausência de estruturas sedimentares, orientação, seleção e fragmentação dos bioclastos e o empacotamento fraco a disperso e feições de alteração dos bioclastos por tempo de exposição na interface água-sedimento denotam condições estáticas do ambiente durante o processo final de deposição. Estas características também sugerem abastecimento do lago por águas subterrâneas, pois produzem menor taxa de alteração dos bioclastos e manutenção das condições químicas da água, como demonstrado pela homogeneidade dos dados geoquímicos. Outros depósitos estudados de micritos também apresentam resultados semelhantes. Há forte presença de indivíduos do gênero Biomphalaria e da Família Hydrobiidae nos depósitos. Dados de campo mostram os depósitos de tufas calcárias na região com extensão maior que as registradas, ocorrendo principalmente próximos aos leitos dos rios atuais, que os dissolvem nos períodos chuvosos. Os depósitos de tufas calcárias da Serra da Bodoquena, principalmente os micríticos, provavelmente foram formados nos últimos 10.000 anos, indicando período mais quente e seco que o atual. Os últimos 2.700 na região podem ser caracterizados por aumento da umidade, extinção dos depósitos micríticos e instalação dos depósitos de tufas de cachoeira e barragens.
Bonito town and surrounding areas in Mato Grosso do Sul state are tourist attractions related with many quaternary carbonate deposits which form waterfalls, dams and render almost zero turbidity waters. That area is part of the National Park of Bodoquena Range and Pantanal Biosphere Reserve (UNESCO). Calcareous tufa are porous rocks formed by calcium carbonate laid down in freshwaters containg a great variety of fossils. They were presented in form of waterfalls, dams and lacustrine sediments, forming unconsolidated micritic deposits, being part of the Xaraés Formation. Micritic deposits are extensive and thick in whole area. Most of the deposits are weathered, partly eroded and distributed in restricted areas. The present study focuses on paleontological, granulometric, and geochemical (major, minor and trace elements, carbon and oxygen isotopes) data. The micritic deposits of Calcário Xaraés Mine in Bonito (MS) are detailed studied. Samples were obtained by auger drilling, also in outcrops area and one orientated centimetric indeformed block for taphomic study. The research was complemented with field study and sampling in the Bodoquena Range, Pantanal and Corumbá. Calcário Xaraés Mine micrites are lacustrine deposits. We described through three events: 1: their base does not contain fossils, but bears oncoids, clayminerals. Isotope data point to a wetter period, 2: ostracods, charophytes and gastropods fossils colonized this episode and homogeneity of isotope data suggest a stable event, 3: freshwater gastropods endured scarce water conditions so colonized the area. The isotope data then was varied suggesting alternated periods of evaporation and humidity. Total water lake evaporation resulted in the mass death of the Biomphalaria gastropod and consequent with diffusion of Idiopyrgus gastropod. Absence of sedimentary structures, bioclastic orientation, selection and fragmentation, weak to dispersal packing bioclast and bioclastic alteration features, are indications of long durantion in the water-sediment interface. These features suggest environmental static conditions during the final deposition. These features also suggest groundwater supplies to the lake, leading to less bioclastic alteration, and maintaing chemical water conditions, such as homogeneity of geochemical data. Other studied micritic deposits show almost the same results. There is strong presence of gastropod Biomphalaria and Hydrobiidae Family on these deposits. Field data show calcareous tufa deposits with an extension larger than the studied area, occurring mainly next to the rivers, which dissolve micritic in the rainy period. Bodoquena Range calcareous tufa deposits, mainly micritic sediments, probably were formed in the last 10.000 years, indicating a hotter and drier period than nowadays. The last 2.700 years in this region can be characterized by humidity increase, micritic deposits extinctions and installation of waterfalls and dams tufa depositions.

Resumen
Les associations fauniques d'ostracodes (crustaces) provenant de 48 affleurements et 5 forages permettent de differencier les paleomilieux developpee en aquitaine ; ceux des environnements continentaux, saumatres, infralittoraux cotiers et phytaux, circalittoraux a epibathyaux. Par ailleurs, elles permettent de distinguer stratigraphiquement le stampien, l'oligocene superieur, l'aquitanien et le burdigalien. La limite stampien/oligocene superieur est tres accusee. Celle de l'oligocene superieur avec l'aquitanien est egalement assez marquee. La transition aquitanien-burdigalien est discrete. Pour ameliorer l'echelle stratigraphique on utilise les methodes de population : analyse des variations morphologiques discontinues (morphes) et continues (taille) : cyamocytheridea strigulosa, cyamocytheridea punctarella et cnestocythere reticulata sont etudiees. Elle revele les types de strategies adaptatives mises en oeuvre lorsqu'elles sont confrontees aux memes changements paleogeographiques, paleoclimatiques et paleotectoniques

Resumen
Le thème principal de ce travail de thèse se rapporte à l'étude micropaléontologique et sédimentologique des dépôts émersifs de la plate-forme jurassienne (S. -E. De la France et Suisse occidentale) entre le Jurassique moyen et le Crétacé inférieur (faciès purbeckiens et wealdiens). Grâce aux données complémentaires de coupes sélectionnées dans le N. -E. De l'Espagne (Maestrazgo) et le S. -E. De la France (Basse-Provence), une biozonation continentale principalement basée sur les Charophytes et un nouveau schéma phylogénétique des Clavatoracées (Charophytes) sont établis pour le Jurassique supérieur - Crétacé de l'Europe occidentale. D'autre part, le polymorphisme des gyrogonites des Porocharacées et des Characées (Charophytes) est mis en évidence avec une révision taxonomique. D'après une comparaison entre les données fossiles du Jurassique-Crétacé avec le matériel récolté dans des environnements similaires de l'Actuel, ce polymorphisme résulte des variations de certains paramètres écologiques (salinité, pH, luminosité, température) influençant la croissance des thalles et des fructifications des Charophytes. L'analyse micropaléontologique et sédimentologique des dépôts émersifs mésozoïques de la plate-forme jurassienne permet en outre de déceler l'activité d'une tectonique synsédimentaire d'origine tardi-hercynienne au Crétacé inférieur (phase néocimmérienne) et de reconnaître un climat subtropical à alternances saisonnières de périodes sèches et humides dans l'intervalle Jurassique moyen - Crétacé inférieur. La présence très particulière dans le Jura de rares restes de Dinosauriens (Allosaurus) et de certaines Characées (Aclistochara bransoni) autorise également à postuler durant le Jurassique supérieur et le Crétacé basal des échanges biologiques entre la marge nord-téthysienne (Eurasie) et l'Amérique du Nord. Plus précisément, d'autres éléments de corrélation (Ostracodes, Charophytes, Dinokystes, Ammonites) originaires respectivement des domaines téthysien ou boréal démontrent la réalité de connexions avec la plate-forme jurassienne au Crétacé basal (Berriasien-Valanginien / Volgien-Ryazanien). Dans ses conclusions, ce travail présente une interprétation séquentielle des dépôts margino-littoraux du Jurassique-Crétacé de la plate-forme jurassienne et évalue l'influence des cycles climatiques glacio-eustatiques ou de la dérive des continents dans la mise en place des faciès d'émersion laguno-lacustres sur les marges continentales et les aires cratoniques. Enfin, la lignée phylogénétique des Hemiglobator-Globator (Clavatoracées, Charophytes) est prise comme exemple significatif pour une réflexion sur la théorie néo-darwiniste de l'Evolution et le créationnisme, apparemment contradictoires mais en fait complémentaires
The main topic of this work concerns the micropaleontological and sedimentological study of the emersive deposits on the Jura platform (S. -E. France and western Switzerland) since the Middle Jurassic to the Lower Cretaceous (Purbeckian and Wealdian facies). By additional data of selected outcrops in N. -E. Spain (Maestrazgo) and S. -E. France (Basse-Provence), a continental biozonation mainly based on the Charophytes and a new phylogenetic diagram of the Clavatoraceae (Charophytes) are set for the Upper Jurassic - Cretaceous of the Western Europe. Moreover, the polymorphous gyrogonites of the Porocharaceae and Characeae (Charophytes) is underlined with a taxonomic review. After a comparison including the Jurassic-Cretaceous fossi! data and the material collected in similar recent environments, this polymorphism is related to the interaction of sorne fluctuating ecologic parameters (salinity, pH, lighting, temperature) on the growth of the Charophytes thallus and fructifications. The micropaleontological and sedimentological analysis of the Jura platform's Mesozoic emersive deposits allows to notice likewise a Lower Cretaceous tectonic activity related to a tardi-hercynian origin and connected with the Neo-Cimmerian phase, as well as to recognize a subtropical climate with alternated seasonal dry and wet periods in the Middle Jurassic - Lower Cretaceous interval. The very particular occurrence in the Jura Mountains of scarce Dinosaurs remains (Allosaurus) and some Characeae (Aclistochara bransoni) agrees to postulate during the Upper Jurassic and the lowermost Cretaceous biological exchanges between the northern Tethyan margin (Eurasia) and North America. More precisely, other correlation tools (Ostracods, Charophytes, Dinokysts, Ammonites) from respectively Tethyan or Boreal realms indicate the evidence of connections with the Jura platform in the lowermost Cretaceous (Berriasian-Valanginian / Volgian-Ryazanian). As conclusions, this study introduces a sequential interpretation of the Jurassic-Cretaceous coastal deposits on the Jura platform and evaluates the share of the glacio-eustatic climatic cycles or of the continental drift inducing the brackish-Iacustrine emersive facies on the continental margins and cratonic areas. At last, the phylogenetic lineage of the Hemiglobator-Globator (Clavatoraceae, Charophytes) is used as a significant exemple to argue about the neo-darwinist theory of Evolution and the creationism, apparently conflicting but in fact complementary

Resumen
Colonial National Historical Park (COLO) in eastern Virginia was established for its historical significance, but significant paleontological resources are also found within its boundaries. The bluffs around Yorktown are composed of sedimentary rocks and deposits of the Yorktown Formation, a marine unit deposited approximately 4.9 to 2.8 million years ago. When the Yorktown Formation was being deposited, the shallow seas were populated by many species of invertebrates, vertebrates, and micro-organisms which have left body fossils and trace fossils behind. Corals, bryozoans, bivalves, gastropods, scaphopods, worms, crabs, ostracodes, echinoids, sharks, bony fishes, whales, and others were abundant. People have long known about the fossils of the Yorktown area. Beginning in the British colonial era, fossiliferous deposits were used to make lime and construct roads, while more consolidated intervals furnished building stone. Large shells were used as plates and dippers. Collection of specimens for study began in the late 17th century, before they were even recognized as fossils. The oldest image of a fossil from North America is of a typical Yorktown Formation shell now known as Chesapecten jeffersonius, probably collected from the Yorktown area and very likely from within what is now COLO. Fossil shells were observed by participants of the 1781 siege of Yorktown, and the landmark known as “Cornwallis Cave” is carved into rock made of shell fragments. Scientific description of Yorktown Formation fossils began in the early 19th century. At least 25 fossil species have been named from specimens known to have been discovered within COLO boundaries, and at least another 96 have been named from specimens potentially discovered within COLO, but with insufficient locality information to be certain. At least a dozen external repositories and probably many more have fossils collected from lands now within COLO, but again limited locality information makes it difficult to be sure. This paleontological resource inventory is the first of its kind for Colonial National Historical Park (COLO). Although COLO fossils have been studied as part of the Northeast Coastal Barrier Network (NCBN; Tweet et al. 2014) and, to a lesser extent, as part of a thematic inventory of caves (Santucci et al. 2001), the park had not received a comprehensive paleontological inventory before this report. This inventory allows for a deeper understanding of the park’s paleontological resources and compiles information from historical papers as well as recently completed field work. In summer 2020, researchers went into the field and collected eight bulk samples from three different localities within COLO. These samples will be added to COLO’s museum collections, making their overall collection more robust. In the future, these samples may be used for educational purposes, both for the general public and for employees of the park.
