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...

Ordovician limestone-marl alternations in the Oslo-Asker District have been interpreted as signaling glacio-eustatic lowstands, which would support a prolonged "Early Palaeozoic Icehouse". However, these rhythmites could alternatively reflect differential diagenesis, without sedimentary trigger. Here, we test both hypotheses through one Darriwilian and three Katian sections. Our methodology con...

Palynology is a long established and respected branch of environmental science that has been applied to criminal investigation in a meaningful way only in recent years. It has proved to be remarkably versatile in many kinds of criminal enquiry. It is not, however, an absolute science; palynological data are on a par with the suites of symptoms which allow medical practitioners to make diagnoses...

Assemblages de palynomorphes et palynofaciès non polliniques du Crétacé inférieur d'Irak: aperçu la paléobiologie paléoenvironnement. La formation Yamama inférieur, dans le sud l'Irak, est bien connue pour être l'un des principaux réservoirs carbonatés pétrole nombreux champs pétrolifères ce secteur. Toutefois, son environnement dépôt a jusqu'à présent été peu décrit à l'aide techniques palynol...

A large population of the acritarch genus Pyloferites Quadros 1999 was recovered from Devonian strata Paraná Basin, Alto Garças Sub-basin (Brazil), at Jaciara section. Based on a literature review and examination new material, including morphometric analyses, shows wide morphological variability, and, therefore, is herein emended. Additionally, species emendation are instituted: escobaides (Cra...
