The Ediacaran–Cambrian transition witnessed some of the most important biological, tectonic, climatic and geochemical changes in Earth's history. Of utmost importance for early animal evolution is likely shift redox conditions bottom waters, which might have taken place distinct pulses during late Ediacaran Paleozoic. To track this transition, we present new trace element, total organic carbon both inorganic isotopes, first iron speciation data on Tamengo Guaicurus formations Corumbá Group...
Abstract The present work presents a detailed taxonomic study on Ostracoda from the Quiricó Formation, Areado Group, São Francisco Basin, Brazil. samples were collected three outcrops in Minas Gerais State: Tereza Farm (João Pinheiro Municipality), and banks of José creeks (Presidente Olegário Municipality). Sixteen ostracode species recovered: Harbinia alta , aff. H . angulata aff crepata salitrensis symmetrica Brasacypris fulfaroi ovum Cypridea conjugata hystrix infima jequiensis...
A biostratigraphic and paleozoogeographic revision of the upper Aptian-Albian ostracods Riachuelo Formation, in Sergipe-Alagoas Basin, Brazil, was conducted.The studied material comprised 336 samples from several outcrops, along with well cores drilled by Petróleo Brasileiro S.A. (PETROBRAS).After taxonomic analysis, including description Reticulocosta edrianae n. sp., a new biozonation scheme obtained for Albian interval that formation, affi nities Brazil-Central West Africa province were...
Two species of Ostracoda are described for the first time from parastratotype-section Vila Maria Formation; this section is 30 m thick, located on northern border Paraná Basin.The Formation records Upper Ordovician-Lower Silurian boundary Basin in Bom Jardim de Goiás, State central Brazil.The new represents earliest occurrence Brazilian strata.Delicate internal and external molds isolated valves abundant basal portion Formation.This interval comprises black shales that record post-glacial...
The Ediacaran is a period characterized by the diversification of early animals and extensive neritic carbonate deposits. These deposits are still not well understood in terms facies carbon isotope composition (δ 13 C). In this study we focus on Tamengo Formation, southwestern Brazil, which constitutes one most continuous well-preserved sedimentary record late South America. We present new detailed lithofacies stable isotopes data from two representative sections (Corcal Laginha) revise...
It is herein presented the unprecedented occurrence of Cloudina carinata Cortijo et al., 2010 in American continent. This new expanded geographic distribution this species, until now reported from sections Spain and Siberia. The assembled biomineralizing metazoans carinata, lucianoi (Beurlen & Sommer, 1957) Corumbella werneri Hahn 1982 are for first time Tamengo Formation, Corumbá Group, Porto Figueiras section, Municipality, Mato Grosso do Sul State, Brazil. could be employed as an...
The recovery of microfossils from Proterozoic rocks is commonly challenging because metamorphism. In this study, an application different methods usually applied on Phanerozoic to test efficiency recovering microfossil units presented. Chemical, physical, and biological factors can influence the microfossils, thereby becoming a barrier for biostratigraphic paleoecological studies. Furthermore, low-cost projects with reduced amount sample collected, such as drill core sampling, need optimize...
Abstract Herein is reported the first occurrence of ostracodes from Iapó Formation, an uppermost Ordovician unit Rio Ivaí Group in Paraná basin, Brazil. Two ostracode species were identified Três Barras Farm section: Harpabollia harparum (Troedsson, 1918) and Satiellina paranaensis Adôrno Salas et al., 2016 recovered dropstone-bearing shale overlying glaciogenic diamictites, a feature typical Hirnantian (uppermost Ordovician) strata throughout Gondwana. The taxonomy Genus , as well its type...
The Três Barras Farm section is an outcrop located at the northern border of Paraná Basin, in Midwest Brazil. Rocks Ordovician-Silurian age are found this section, represented by Iapó and Vila Maria formations Rio Ivaí Group, which directly overlay crystalline basement. Devonian rocks Furnas Formation also observable top section. Although first fieldwork conducted there dates back to 1985, has been visited different generations researchers, often executing paleontological studies. fossil...
Este estudio presenta una actualización del registro isotópico de la Formación Tamengo, parte superior Grupo Corumbá, que se encuentra en meridional Cinturón Paraguayo. trabajo incluye cortes estratigráficos detallados enlazados con geoquímica alta resolución δ13C y δ18O dos yacimientos mineros cercanos a Corumbá (Mato Grosso do Sul, Brasil).
Se presenta en este trabajo el análisis paleontológico de 26 especies fósiles muestradas cinco cortes las Formaciones Tamengo y Guaicurus regines Corumbá Ladário: canteras Corcal Laginha, Porto Sobramil, Figueiras Ecoparque Cacimba. Además, se añaden varias interpretaciones paleoecológicas ambientales, basadas registro fósil. Cloudina carinata Cortijo et al., 2010, previamente citada España Siberia, aparece por primera vez continente Americano, concretamente limolitas la Formación corte...
