A comprehensive review and study of the rich dinosaur track record of the Tremp Formation in the southern Pyrenees of Spain (Southwestern Europe) shows a unique succession of footprint localities prior to the end-Cretaceous mass extinction event. A description of some 30 new tracksites and data on sedimentary environments, track occurrence and preservation, ichnology and chronostratigraphy are ...

High resolution benthic oxygen isotope records combined with radiocarbon datings, from cores retrieved in the North, Equatorial, and South Atlantic are used to establish a reliable chronostratigraphy for the last 60 ky. This common temporal framework enables us to study the timing of the sub-Milankovitch climate variability in the entire surface Atlantic during this period, as re#ected in plank...

Fossil-wood carbon-isotope data are presented for the Wessex Formation, a non-marine unit within the Lower Cretaceous (Valanginian–Barremian) Wealden Group of the Isle of Wight and Dorset, southern England. The carbon-isotope values have a range ( C c. 26.6 to 19.8‰) that is consistent with that expected for Mesozoic C3 plants. Consideration of the Isle of Wight fossil-wood carbon-isotope data ...

The current Triassic chronostratigraphic scale is a hierarchy of three series divided into seven stages, divided further into 15 substages. Ammonoid and conodont biostratigraphies provide the primary basis for chronostratigraphic definition based on global stratotype sections and points (GSSP). I propose that Triassic chronostratigraphic definition should rely entirely on ammonoid biochronologi...

We reconstruct a Plio-Pleistocene microscopic tephrostratigraphy for DSDP Site 231 in the Gulf of Aden. Systematic microtephrostratigraphy increases the potential for identifying tephra horizons for regional stratigraphic correlation and age control, as well as providing information about eruptive histories. Microtephra reveal three main pulses of volcanism c. 4.0–3.2 Ma, 2.4 Ma and 1.7–1.3 Ma,...

A stratigraphy of a buried travertine deposit was developed using stable isotope geochemistry, trace elements, and radiometric dating. The identified in well at Prima Porta (north Rome, Italy), located the western boundary Tiber Valley, morpho-tectonic depression extensional origin. It deposited close to spring that discharged groundwaters from nearby volcanic aquifer associated with rise deep-...

ABSTRACT Caves containing perennial ice deposits make up a little-known, but emerging part of the cryosphere under increasing scrutiny from scientific community. M-17, sag-type cave opening at 1879 m asl in Tolminski Migovec massif Julian Alps (NW Slovenia) contains underground deposit whose paleoclimate sensitivity is poorly understood and longevity current climate change risk. The past mass b...

The neritic region of the Chaoshan plain is located on northeastern (NE) boundary South China Sea (SCS). Despite extensive research stratigraphic architecture and sedimentary processes within plain, neighboring area remains largely unexplored. In this study, we provide a new set ages seventeen quartz optically stimulated luminescence (OSL) dating results from four cores (SY2-2, SY3-1, SY3-2, HS...
