A 95 m thick succession of grey siliceous limestone and marl on Mount Rettenstein in the Northern Calcareous Alps allowed us to study well-preserved diverse radiolarian assemblages across Sinemurian–Pliensbachian boundary. The distribution 31 most characteristic species is presented. Ammonites Jamesoni Subzone, topmost subzone Zone, have been previously found upper part section. data are complemented with calcareous nannofossil biostratigraphy, carbon strontium isotope analyses bulk...
Abstract Quantitative analysis performed on latest Pliensbachian–early Toarcian calcareous nannofossil assemblages from the Camino section (Basque Cantabrian Basin) allowed their response to environmental changes recorded during this time interval be deciphered, characterized by an extinction event. The results were introduced within a principal component and compared with stable isotope total organic carbon curves. During Pliensbachian, Mirabile lowermost part of Semicelatum Ammonite...
Abstract Pelagic sediments from the subtropical South Atlantic Ocean contain geographically extensive Oligocene ooze and chalk layers that consist almost entirely of calcareous nannofossil Braarudosphaera . Poor recovery lack precise dating these horizons in previous studies has limited understanding number acmes, their timing durations, therefore likely cause. Here we present a high‐resolution, astronomically tuned stratigraphy oozes (29.5–27.9 Ma) Drilling Program Site 1264 southeastern...
This paper studies ten Subbetic (Betic External Zones) stratigraphic sections spanning the Pliensbachian–early Toarcian time interval. Eight lithofacies were distinguished: crinoidal limestones, peloidal breccias, cherty nodular hardground surfaces and condensed levels, marls marly limestone alternance, dark marls. The biostratigraphy matches data from ammonite calcareous nannofossil zonations. In addition, we analyzed C O isotopes bulk samples three of studied in which lower sedimentation...
Se estudian los nanofosiles calcareos identificados en materiales del Pliensbachiense de la seccion Tudanca (Cuenca Vasco-Cantabrica, Espana). han reconocido doscientos catorce niveles estratigraficos constituidos, fundamentalmente, por una alternancia margas y calizas, que se tomado un total sesenta cinco muestras. ha realizado analisis semicuantitativo sobre las smear slides preparadas observandose, mayoria ellas, estado preservacion malo a moderado abundancia rara frecuente....
Belemnites were a type of cephalopod abundant in the Jurassic and Cretaceous, whose fossils have been extensively used for paleo-oceanographic studies. For this study, we analyzed 69 elements by Inductively Coupled Plasma-Sector Field Mass Spectrometry (ICP-SFMS) 15 belemnite rostra from West Rodiles section Asturian Basin, Northern Spain. We aim to determine if carbonate chemistry reflects changes seawater during Late Pliensbachian–Early Toarcian time interval examine how belemnites can be...
The paper by Magalhães et al. (2023) concerns the Jurassic coastal outcrop between Consolação and São Bernardino beaches, in western-central Lusitanian Basin (LB), Portugal (Figure 1). authors used a sequence stratigraphic approach, defining multi-scale cycles and, based on nannofossils dinoflagellate cysts (dinocysts) data, they re-assigned section to Middle ‘Candeeiros Formation’; formerly had been established as part of Upper Alcobaça Formation (namely Fürsich al., 2022; Leinfelder, 1986;...
