Supply and uses of wood in Auvergne, from the Iron Age in the Middle Ages

2018

Waterlogged woods are rare discoveries in archeology because of the conditions inherent in their conservation. When they reach us, they give a lot of data on the importance of this material for past populations.Auvergne is a privileged context for their conservation. Thousands of woods from fortuitous discoveries or archaeological excavations are dated from the Neolithic to the modern era, however the corpus covers mostly the Second Iron Age until the Middle Ages.The diversity of the woods enables a better understanding of different uses according to their respective destination.The state of conservation of many elements gives information about the different stages of shaping, from the fell…

Environmental and depositional controls on laminated freshwater carbonates: An example from the Roman aqueduct of Patara, Turkey

2013

Carbonate deposits in aqueducts are a new high-resolution data source for environmental changes during the time of the Roman Empire, notably in the fields of palaeoclimate and spring hydrology. In order to distinguish environmental effects from those related to depositional setting, laminated carbonate deposits were compared along the entire length of an ancient aqueduct channel at Patara, Turkey. The carbonate deposits, up to 80mm in thickness, are composed of lamina couplets up to 1mm thick of alternating porous microspar and dense, columnar sparite. The former formed in the dry, warm season and the latter in the wet, cool season. The presence of biofilms seems to play a role in the devel…

A 4500 year record of palaeomagnetic secular variation and relative palaeointensity from the Tyrrhenian Sea

2020

A marine sediment core from the western Mediterranean provides a newhigh-resolution 4,500-year record of palaeomagnetic secular variation and relativepalaeointensity. In 2013, the 7.1-metre C5 core was recovered from the TyrrhenianSea as part of the NextData climate data project. The coring site, 15 km offshorefrom the Volturno river mouth, is well-located to record combined marine andterrestrial palaeoclimatic influences, and the fine-grained, rapidly deposited sedimentsare effective palaeomagnetic recorders. We investigate the palaeomagnetic field direction and strength recorded in the core, which provide a valuable high-resolution recordof Holocene geomagnetic variation in the area. Usin…

Central Iberian Mediterranean as refugium (MIS 5–3). Data and script

2020

Se aporta por un lado los datos base de los restos arqueobotánicos y arqueozoológicos identificados en yacimientos del Paleolítico medio y superior de la región central del Mediterráneo ibérico (Cova Negra, Abrigo de la Quebrada, Cova de les Malladetes y Cova de les Cendres). Y por otro, el script generado en el software R (con el paquete "Vegan") para calcular diferentes índices de diversidad. Todo ello utilizado en el artículo "Could the central Iberian Mediterranean region be defined as a refugium? Fauna and flora in MIS 5–3 and their implications for Palaeolithic human behaviour".

HIGH-RESOLUTION PALAEONVIRONMENTAL RECONSTRUCTION OF ODP HOLE 963D (SICILY CHANNEL) DURING THE LAST DEGLACIATION BASED ON CALCAREOUS NANNOFOSSILS

2004

Abstract A palaeoenvironmental reconstruction of Ocean Drilling Program (ODP) Hole 963D (Sicily Channel) has been obtained on the basis of quantitative abundance fluctuations in the calcareous nannofossil assemblages. The studied hole is characterized by a very high sedimentary resolution and covers the last ca. 20 kyr. A new palaeoclimatic curve, based on the Gephyrocapsa muellerae/Upper Photic Zone (UPZ) group ratio, permitted the detection of the rapid climatic fluctuations that characterized the last deglaciation. Cold water masses occupied the Sicily Channel during the glacial period and the Younger Dryas, whereas they were generally warm during the Bolling–Allerod and the Holocene. An…

Palaeontological Virtual Congress: A new way to make science

2019

On the first month of 2018, one of the authors (VDC) of this preface had an interesting idea: to hold a virtual congress. At first, he did not know of the existence of this kind of congress, but a quick internet search showed him that there were some examples in the fields of medicine and veterinary medicine; however, it had never been done in palaeontology. For that reason, with the help of other co-workers from the Universitat de València, Museo Paleontológico de Alpuente and Museu Valencià d’Historia Natural, we decided to undertake this adventure.

YTTRIUM AND REE SIGNATURE RECOGNIZED IN CENTRAL MEDITERRANEAN SEA (ODP SITE 963) DURING THE MIS 6 – MIS 5 TRANSITION

2010

The Mediterranean Sea acts as a miniature ocean with the development of its own conveyor belt. It constitutes an ideal location to study and forecast how the marine environment responds to rapid climatic change. Here we present a palaeoenvironmental study carried out on the sediments of ODP Site 963, recovered in the Sicily Channel, the sill which divides the western from the eastern Mediterranean basin. We focused on the transition between the penultimate glacial (MIS 6) and the last interglacial (MIS 5), between approximately 130 and 115 kyr BP. A novel approach is proposed, taking into account centennial-scale geochemical data on major elements, selected trace elements, and yttrium and R…
