Paleoecology of late cretaceous coccolithophores

, 2021
Coccolithophores, common primary producers in Mesozoic, Cenozoic, and present oceans, are significant components of the earth’s biogeochemical cycles. Being the most productive calcifying organism on earth, their carbonate oozes play a major role in fixing \(CO_2\), thereby forming the most important long-term \(CO_2\) sink throughout the last 100 Ma ...

High elevation of the ‘Nevadaplano’ during the Late Cretaceous

Earth and Planetary Science Letters, 2014
During the Late Cretaceous, central Nevada may have been a high elevation plateau, the Nevadaplano; some geodynamic models of the western US require thickened crust and high elevations during the Mesozoic to drive the subsequent tectonic events of the Cenozoic while other models do not. To test the hypothesis of high elevations during the late Mesozoic,

High temperatures in the Late Cretaceous Arctic Ocean

Nature, 2004
To understand the climate dynamics of the warm, equable greenhouse world of the Late Cretaceous period, it is important to determine polar palaeotemperatures. The early palaeoceanographic history of the Arctic Ocean has, however, remained largely unknown, because the sea floor and underlying deposits are usually inaccessible beneath a cover of floating

Discovery of chemosynthesis-based association on the Cretaceous basal leatherback sea turtle from Japan

Acta Palaeontologica Polonica, 2017
We report a Late Cretaceous chemosynthetic community fueled by decomposing basal leatherback sea turtle on the ocean floor in the western Pacific. The fossil association representing this community has been recovered from the matrix of a concretion ...

Late Cretaceous Aquatic Plant World in Patagonia, Argentina

PLoS ONE, 2014
Dans cette contribution, nous décrivons les dernières communautés de plantes aquatiques du Crétacé de la Formation de La Colonia, en Patagonie, en Argentine, en fonction de leurs composantes taxonomiques et de leurs attributs paléoécologiques. La Formation de La Colonia est une unité géologique déposée lors d'un épisode transgressif maastrichtiano ...

Hadrosauroid Dinosaurs from the Late Cretaceous of the Sultanate of Oman

PLOS ONE, 2015
Fragmentary post-cranial remains (femora, tibia, vertebrae) of ornithischian dinosaurs from the Late Cretaceous of the Sultanate of Oman are described and referred to hadrosauroids. The specimens come from the Al-Khod Conglomerate, of latest Campanian to Maastrichtian age, in the north-eastern part of the country.

Late Cretaceous paleogeodynamics of Bulgaria

Geologica Balcanica, 1993
The Tethyan system consisted in the Late Cretaceous of four plates, and namely Eurasia, the Oceanic Neotethys, Apulia (+ Menderes) and Africa (+Arabia). The Balkan microcontinent was situated between the Neotethys (Vardar ocean) and the Dobrogea cimmerian orogen. It was an integral whole (Albian-Turonian), or was fragmented through extension (Coniacian

Late Cretaceous Tectono-Metamorphic Events in the Skyros Upper Metamorphic Unit (Olympus Mountain), Aegean Sea, Greece

Geosciences
Late Cretaceous metamorphic events are known in Crete and the Cyclades from klippen above the External Hellenides. This work extends their occurrence to the North Aegean area within the tectonic units of the Internal Hellenides.

A complete skull of an early cretaceous sauropod and the evolution of advanced titanosaurians.

PLoS ONE, 2011
Advanced titanosaurian sauropods, such as nemegtosaurids and saltasaurids, were diverse and one of the most important groups of herbivores in the terrestrial biotas of the Late Cretaceous.
