The Jurassic/Cretaceous transition was accompanied by significant changes in palaeoceanography and palaeoenvironments the Tethyan Realm, but outside Tethys such data are very scarce. Here we present results of a study most complete section Panboreal Superrealm, Nordvik section. Belemnite δ18O show an irregular decrease from values reaching up to +1.6‰ Middle Oxfordian +0.8 −1.7‰ basal Ryazanian, indicating prolonged warming. biodiversity were strongly related sea-level oscillations, showing...
Here in the first part of this publication we discuss possibilities for selection a GSSP Berriasian Stage Cretaceous System, based on established methods correlation Tithonian/Berriasian interval. This will be followed, second part, by an account stratigraphic evidence that justifies locality Tré Maroua (Hautes-Alpes, SE France) as proposed GSSP. historical J/K boundary interval, and evolution thinking positioning over recent generations, relation to research last ten years. The level is...
This paper presents the results of a detailed study Bajocian-Bathonian sections in “Sokur” Quarry near city Saratov and borehole drilled same quarry. The these boundary beds, unique for Boreal-Tethyan ecotone, offers solution to much-debated problem Middle Jurassic correlation. BajocianBathonian beds this section contain both Peri-Tethyan Boreal ammonite species, allowing recognition zones associated “Boreal” Bathonian based on belemnites, bivalves, foraminifers. integrated biostratigraphy...
In part 1 of this work we discussed the possibilities for selection a GSSP Berriasian Stage Cretaceous System, based on prevailing practical methods correlation in that J/K interval, traditional usage and consensus over best boundary markers had developed last forty years. This has further, results multidisciplinary studies numerous sites decade. Here Part 2 give an account application those by Working Group (ISCS), present stratigraphic evidence justifies locality Tré Maroua (Hautes-Alpes,...
Abstract The reality of the global‐scale sedimentation breaks remains controversial. A compilation data on Jurassic–Cretaceous unconformities in a number regions with different tectonic settings and character sedimentation, where new or updated stratigraphic frameworks are established, permits their correlation. Unconformities from three large reference regions, including North America, Gulf Mexico, Western Europe, were also considered. unconformities, which encompass Jurassic‐Cretaceous,...
This paper presents a refined belemnite based biostratigraphy for the Bajocian-Bathonian transition in Yuryung-Tumus peninsula (northern Siberia, Russia). A revision of Siberian zonation is proposed. Herein two new biostratigraphic units are introduced: Paramegateuthis subishmensis Zone (upper part Lower Bajocian) and ishmensis (Lower-Middle Bathonian boundary interval). STOYANOVA-VERGILOVA, recorded first time Siberia previously only known from Bulgaria (Sub-Mediterranean domain), provides...
