The Cenozoic palaeoenvironment of the Arctic Ocean [PDF]

open access: yesNature, 2006
The history of the Arctic Ocean during the Cenozoic era (0-65 million years ago) is largely unknown from direct evidence. Here we present a Cenozoic palaeoceanographic record constructed from >400 m of sediment core from a recent drilling expedition to the Lomonosov ridge in the Arctic Ocean.

Why Mesolithic Populations Started Eating Crabs on the European Atlantic Façade Only Over the Past 15 Years?

open access: yesOpen Archaeology, 2022
Mesolithic populations from coastal areas are known as hunter-gatherer-fishers. This way of life is visible in the landscape owing to the presence of large accumulations of shells named shell middens. These anthropogenic refuse heaps are composed of high

The palaeoecology of two Scottish encrinites: Jurassic crinoid assemblages from the Trotternish Peninsula, Isle of Skye, Scotland [PDF]

open access: yes, 2009
Despite a long history of investigation, articulate crinoids from the Jurassic of Scotland have not received great attention compared to their counterparts in Southern England or continental Europe; this is thought to be largely due to poor preservation.

Holocene evolution of the Banni Plain at the north‐east margin of the Arabian Sea: Constraints from a ca 50 m long sediment core

open access: yesThe Depositional Record, 2023
Holocene evolutionary history of the Banni Plain in the Great Rann of the Kachchh Basin is reconstructed from a subsurface sediment core of ca 50 m. Detailed data on textural and lithofacies variations, grain‐size analysis, environmental magnetism and ...

Détection de sites de la Préhistoire ancienne sur le chantier du contournement ouest de Strasbourg

open access: yesArchéopages, 2022
The loess soils of Alsace were identified for many years as having great potential for the preservation of ancient prehistoric occupations and the recording of palaeo-environmental data.

Palynofacies, palaeoenvironments and petroleum [PDF]

open access: yesJournal of Micropalaeontology, 1982
Abstract. During the past decade, transmitted light microscopy of dispersed organic particles has become an important tool for assessing the petroleum potential of sedimentary basins. The main components of palynofacies and the colours of the microfossils preserved therein are widely used in the oil industry to aid the determination of organic ...

Trilobites, their traces and associated sedimentary structures as indicators of the Cambrian palaeoenvironment of the Ociesęki Range (Holy Cross Mountains, Poland) [PDF]

open access: yes, 2013
Enrolled specimens of trilobite species Strenuella polonica, partly preserved within their escape structures and burrows from the Cambrian Series 2 Ociesęki Sandstone Formation, are described. The specimens are interpreted as buried during storm episodes.

Peuplements paléolithiques et paléoenvironnements pléistocènes dans le Massif central

open access: yesArchéopages, 2022
During the last decades, the deployment of preventive operations related to ancient Prehistory in Auvergne permitted the exposure of many sites, whose contribution appears to be complementary to that of great historic locations.

Land Snail Extinctions at Kalaeloa, O`ahu

open access: yesInternet Archaeology, 2001
In this article we show that the interpretation of Polynesian influence drawn from the stratigraphic record of sub-fossil land snails at Kalaeloa (O'ahu, Hawai'i) is based on a unique stratigraphic sequence at a single sinkhole.
