The town of Rue was one the most important coastal harbours Picardy, Northern France, from beginning 12th century to end 15th CE. Document sources and ancient maps confirm existence this vibrant harbour. Until now, however, no palaeoenvironmental studies have attempted reconstruct configuration region's coastline during medieval times. Here we employ a geoarchaeological approach Mid-to Late Hol...

The late Paleozoic ice age (LPIA) during the Carboniferous and Permian (ca. 360–260 Ma) was vegetated Earth's only recorded icehouse-to-greenhouse transition provides a deep-time perspective for climate-glaciation-environment coevolution future climate change. During LPIA, changes in glacial-interglacial cycles have been closely linked to atmospheric pCO2. In this paper, we investigate relation...

The 100 m thick stratigraphic section exposed at Dinosaur Provincial Park (DPP, southern Alberta) contains bentonites that have been used for more than 30 years to date DPP's rocks and fossils using the K-Ar decay scheme. Limited reproducibility among different vintages of 40Ar/39Ar ages inhibited development a high resolution chronostratigraphy. Here we employ further test recently completed C...

A Hildoglochiceras -rich horizon is reported from a thin carbonate intercalation within the siliciclastic Upper Jurassic Jhuran Formation of Jara Dome, western Kachchh Mainland. The specimens have been used for first population-level study genus based on multivariate analysis. High phenotype instability in large sample confirms occurrence transient forms between morphospecies. Key morphological...

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 comple...

A 10Be/9Be-based chronostratigraphy has been determined for ODP 181, Site 1121 sediment core, recovered from the foot of the Campbell Plateau, Southwest Pacific Ocean. This core was drilled through the Campbell ‘skin drift’ in ca. 4500 m water depth on the mid-western margin of the extensive Campbell Nodule Field, beneath the flow of the major cold-water Deep Western Boundary Current (DWBC). In...

The paper presents the results of optical dating of potassium-rich feldspar grains obtained from the Haua Fteah cave in Cyrenaica, northeast Libya, focussing on the chronology of the Deep Sounding excavated by Charles McBurney in the 1950s and re-excavated recently. Samples were also collected from a 1.25 m-deep trench (Trench S) excavated during the present project below the basal level of the...
