Abstract The Toarcian Oceanic Anoxic Event (T-OAE, c . 182 Ma) represents a major perturbation of the carbon cycle marked by widespread black shale deposition. Consequently, onset T-OAE has been linked to combined effects global warming, high productivity, basin restriction and salinity stratification. However, processes that led termination event remain elusive. Here, we present palynological data from Arctic Siberia (Russia), Viking Corridor (offshore Norway) Yorkshire Coast (UK), all...
Abstract The Early Cretaceous Weissert event, characterized by a positive carbon isotope excursion and coincident with the Paraná‐Etendeka volcanism, saw biogeochemical chain of events that ultimately led to an increase in burial. A conclusive link between volcanism its impact upon environment remains, however, elusive. Here we reconstruct temperature through event from Mg/Ca ratios belemnites Vocontian Trough (France) SE Spain use isotopes our reconstruction marine records cycling. We...
The Mg/Ca, Sr/Ca, δ18O and δ13C compositions are given for well-preserved specimens of ten belemnite species/genera from three stratigraphic intervals. data help assess the use these proxies palaeo-oceanography. Samples Dorset, UK (Pliensbachian; 5 species); Cambridgeshire, (Callovian; 1 Vocontian Basin, SE France (Valanginian; 4 genera). In none populations (at species or genera level) does Mg/Ca correlate with δ18O. Neither do values along a microsampled radial profile across single...
Abstract The late Oligocene–early Miocene interval records a discernable episode of phosphorite formation, which is considered as the first four main phosphogenic episodes during early and Cenozoic. In order to better constrain processes leading widespread formation we present new radiometric, geochemical, palynological, sedimentological data from drill core Roca Fosfórica Mexicana mine at San Juan de la Costa, Baja California Sur (Mexico). this region, phosphogenesis was enabled by...
Abstract The Middle Jurassic–Lower Cretaceous in the eastern Dutch offshore provides excellent examples of sand-rich sediments that locally accumulated vicinity rift basin margins affected by salt tectonics. These types deposits are often geographically restricted and difficult to identify, but can be valuable targets for hydrocarbon exploration. distribution, thickness preservation potential fluvio-lacustrine, shallow- deep-marine is discussed provide new insights into regional local...
High-resolution ammonite, belemnite and stable isotope record from the most complete Upper Jurassic section of Bakony Mts (Transdanubian Range, Hungary) This research focuses on cephalopod fauna biostratigraphy latest succession Lókút Hill (Bakony Mts, Transdanubia, Hungary). Fossils were collected bed-by-bed Ammonitico Rosso facies subsequent Biancone type rock. The poorly preserved cephalopods lowermost part profile, immediately above radiolarite, may represent a Oxfordian stage. rich...
The classical papers of Raspail (1829, 1830) and Duval-Jouve (1841) described a wide range belemnite species, mainly from the Lower Cretaceous Castellane-Peyroules area (Alpes de Haute-Provence, France). present work focuses on biostratigraphy these previously taxa for their stratigraphic relationships had not been determined precisely. Here, is related to lithologic successions faunal associations (ammonites) various outcrops in studied. Complementary data were obtained La Lagne, Les...
The first record of belemnites from fossil hydrothermal vent sites in the Mecsek Mountains Hungary emphasizes occurrences Mesozoic chemosynthetic-microbial based ecosystems reported only cold seep carbonates to date. From outer shelf-upper bathyal (<300 m) site latest Valanginian - Early Hauterivian taxa Adiakritobelus (?), Hibolithes, Duvalia, and Pseudobelus (belemnites) organic-walled dinoflagellate cysts (a.o. Spiniferites dentatus) are reported. laterally extending hemipelagic facies...
This paper deals with the distribution of belemnites in latest Hauterivian to early Bedoulian Angles Barremian Stratotype Section (ABSS). The ABSS is not uniform, mainly due inaccessibility certain beds. To cover this, and compare more proximal settings, we investigated a section north Le Bourguet. sediments yield Hibolithes ex gr. subfusiformis besides some Duvalia dilatata. earliest deliver richer association that yields last spp. first typical occur just one bed above...
A zonation based on the temporal distribution of belemnites is presented for Valanginian and its boundaries. It calibrated ammonite controlled bed-by-bed correlated sections from pre-Vocontian Basin (southeast France). Three new are introduced herein that have previously not been investigated. All together, seven zones six subzones introduced. In addition, both within Vocontian area, as well outside (Bulgaria, Crimea, Czech Republic, France, Hungary, Morocco, Romania, Slovakia, Spain,...
Abstract Herein, Ryazanian (Berriasian) macrofossils from three well cores in the Central Graben (wells B18-02, L06-02, The Netherlands) and on Jæren High (well 7/7-2, Norway) southern North Sea region are described. Macrofossils mainly represented by buchiid bivalves ( Buchia volgensis ) ammonites Surites , Lynnia Praetollia ?). genus is recorded for first time outside its topotypical area, systematic position stratigraphic ranges discussed. Additionally, studied core sections yielded...
Abstract Based on a new cored succession at Winterswijk, evidence is uncovered of the end-Triassic mass-extinction (ETME) event in subsurface sedimentary Netherlands. The ETME was one most devastating events for biosphere during Phanerozoic era. Massive volcanism from Central Atlantic Magmatic Province initiated breakup supercontinent Pangea and resulted terrestrial marine extinction pulses, which drastically altered course life Earth. newly material reveals representing shallow setting...
Fossil ikaite, preserved as the pseudomorph glendonite, occurs in vast amounts Jurassic and Cretaceous successions high Arctic. Thermodynamics predict that ikaite is only stable at near-freezing temperatures glendonite thus widely used a paleo-indicator of cold climate conditions, conflicting with traditional views very warm equable Mesozoic greenhouse. Here, we show based on multi-proxy investigation glendonites from Siberia Svalbard this one-dimensional view detracts their exceedingly...
