Inventory and assessment of geoarchaeosites in the Middle Eure Valley (Paris Basin, France): An integrated approach to geoarchaeological heritage

open access: yesInternational Journal of Geoheritage and Parks, 2023
For the last decade, there has been an abundance of scattered case studies on geoarchaeological heritage in the scientific literature. Yet, there is a lack of methodological guidelines to inventory and numerically assess a collection of “geoarchaeosites”

The Giant Marine Gastropod Campanile Giganteum (Lamarck, 1804) as a High‐Resolution Archive of Seasonality in the Eocene Greenhouse World

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Giant gastropods are among the largest mollusks in the fossil record, but their potential as paleoseasonality archives has received little attention.

The circulation of Ghlin flint during the time of the Blicquy - Villeneuve-Saint-Germain culture (Early Neolithic)

open access: yesJournal of Lithic Studies, 2014
In the North of France and Belgium, the Blicquy - Villeneuve-Saint-Germain culture marks the end of the Early Neolithic Period (beginning of the 5th millennium).

Million-year-scale alternation of warm–humid and semi-arid periods as a mid-latitude climate mode in the Early Jurassic (late Sinemurian, Laurasian Seaway) [PDF]

open access: yesClimate of the Past, 2021
Clay mineral and stable isotope (C, O) data are reported from the upper Sinemurian (Lower Jurassic) of the Cardigan Bay Basin (Llanbedr–Mochras Farm borehole, northwestern Wales) and the Paris Basin (Montcornet borehole, northern France) to highlight the

Residence time of Chalk groundwaters in the Paris Basin and the North German Basin: a geochemical approach [PDF]

open access: yesApplied Geochemistry, 1998
The comparative geochemical and isotopic study of confined and unconfined Chalk groundwaters of the Paris Basin and the N German Basin proves a significant chemical evolution during groundwater flow from the recharge zones to the deep confined aquifer. Different time dependent geochemical parameters have been tested as dating tools: Cation ratios (Sr2+/

A new fossil ichneumon wasp from the Lowermost Eocene amber of Paris Basin (France), with a checklist of fossil Ichneumonoidea s.l. (Insecta: Hymenoptera: Ichneumonidae: Metopiinae)

open access: yesGeologica Acta, 2004
We describe a new fossil genus and species Palaeometopius eocenicus of Ichneumonidae Metopiinae (Insecta: Hymenoptera), from the Lowermost Eocene amber of the Paris Basin. A list of the described fossil Ichneumonidae is proposed.

Asymétries directionnelles et fluctuantes en période périnatale : étude exploratoire dans les populations du passé

open access: yesBulletins et Mémoires de la Société d’Anthropologie de Paris, 2021
Directional asymmetry (the preferential expression of a character on one side rather than the other) and fluctuating asymmetry (minor, random and independent deviations from bilateral symmetry) are increasingly investigated in modern corpuses of deceased

Thermal evolution of the intracratonic Paris Basin: Insights from 3D basin modelling

open access: yesMarine and Petroleum Geology, 2020
The thermal evolution of the Paris Basin (PB) has been widely studied using 1D, 2D and, more rarely, 3D thermal models. It is well documented that the PB experienced higher temperatures in the past compared to what is currently observed. However, a quantitative analysis of the main processes and parameters that affect the temperature distribution, at ...

The Functional and Symbolic Value of Grinding Stone Tools from the Late Bandkeramik of North-Western Europe

open access: yesInternet Archaeology, 2009
The arrival of late LBK populations in north-western Europe (Hainaut, Hesbaye and the Paris Basin) was accompanied by a change in the functional and symbolic practices related to grinding stone tools. Contrary to former LBK practices, grinding tools were
