Abstract Episodes of Environmental Change (EECs) were times of accelerated hydrological cycle that punctuated the Early Cretaceous. Uncertainties in the geologic time scales …
Early marine seafloor lithification of carbonate sediments leads to the formation of hardgrounds and is known from rocks as old as the Proterozoic. Hardground surfaces …
A detailed investigation of a glauconite bed within the Late Cretaceous Bryozoan Limestone Formation of the Bagh Group in central India, as well as the study of existing records, reveals …
The ages and durations of the stages in the Early Cretaceous commonly show discrepancies of several million years when the Geologic Time Scale (2020) from the …
Abstract Spumellaria (Radiolaria, Rhizaria) are holoplanktonic amoeboid protists, ubiquitous and abundant in the global ocean. Their silicified skeleton preserves very well in sediments …
Abstract The Late Jurassic–Early Cretaceous is an interval of unstandardized stages and includes the only Mesozoic system boundary without a Global Boundary Stratotype Section …
The recognition of regional ammonite bio-events spanning the late Barremian–early Aptian interval in Provence invalidates previous chronostratigraphic models of the Urgonian …
We present new quantitative calcareous nannofossil data from a Barremian (Early Cretaceous) black shale interval of the Boreal Realm. Thirty samples from two sections in …
Two sections in the Subbetic domain of the Betic Cordillera (Río Argos and Arroyo Gilico), encompassing the latest Hauterivian–earliest late Barremian interval, and including the …
