Landscape and fuel management in the context of prehistoric and historical occupations of Cova des Moro (Manacor, Mallorca, Spain)

2021

Abstract In this paper, the first results of charcoal analyses carried out at Cova des Moro (Manacor, Mallorca, Spain) are presented. This cave is an archaeological but also palaeontological site that provides information on endemic fauna (the extinct caprine Myotragus balearicus) before the arrival of humans and, later, the relationship between the first farmers and the landscape. Several human occupations in the cave have been documented, from the Chalcolithic (end of the 3rd millennium cal BC), the Bronze Age (2nd millennium cal BC) and, finally, the Almohad period (13th century AD), during which the cave was used for different purposes. The first results of charcoal analyses at Cova des…

Dietary evidence from Central Asian Neanderthals: A combined isotope and plant microremains approach at Chagyrskaya Cave (Altai, Russia).

2021

Neanderthals are known primarily from their habitation of Western Eurasia, but they also populated large expanses of Northern Asia for thousands of years. Owing to a sparse archaeological record, relatively little is known about these eastern Neanderthal populations. Unlike in their western range, there are limited zooarchaeological and paleobotanical studies that inform us about the nature of their subsistence. Here, we perform a combined analysis of carbon and nitrogen stable isotopes on bone collagen and microbotanical remains in dental calculus to reconstruct the diet of eastern Neanderthals at Chagyrskaya Cave in the Altai Mountains of Southern Siberia, Russia. Stable isotopes identify…

L’étude archéologique des mortiers de chaux médiévaux : vers une meilleure compréhension des gestes du maçon

2020

International audience; Ces dernières décennies, l’étude des mortiers archéologiques, en particulier médiévaux, a connu un essor considérable en lien étroit avec celui de l’archéologie du bâti. Matériaux composites, possédant à la fois une forte identité géologique et un caractère anthropique certain, les mortiers sont considérés comme étant des marqueurs chronologiques potentiels pouvant aider à la compréhension de l’évolution d’un bâtiment. Mais, au-delà des problèmes de chronologie, l’étude du mortier de chaux, qui représente près de la moitié du volume d’une maçonnerie, a permis également de progresser sur la connaissance de toute la chaîne opératoire associée. Ainsi, du four à chaux au…

Economic Conditions in the Area Around the Sea of Galilee in Pre-Hellenistic Times

2017

Abstract In a landscape archaeology project all the fertile fields around the Sea of Galilee (an area of 50 × 30 km) were mapped. The whole territory was subdivided in 5 regions: Jordan valley, Lower Galilee, Upper Galilee, Golan and Transjordanian Hill Country. Additionally all ancient sites from the Neolithic to the Persian period, which are mentioned in archaeological literature, were collected – all together more than 300 sites. These data allow a reconstruction of the economic conditions in antiquity in the area around the Sea of Galilee. Landscape archaeology clearly demonstrates that the economic basis may have been completely diverse in the five sub-regions, and also during differen…

À l’aube des villes antiques : vocabulaire de la cité et formes urbaines. – Introduction

2020

How to envisage research on the ancient city? What are the most appropriate instruments to analyse it? What are the relationships between the emergence of the city as an independent community and the urbanization as archaeology can restore it? Without claiming to resolve these difficult questions, the contributions gathered here show that urbanization and the definitions of the ancient city used by contemporary historians and archaeologists are far from being precisely determined; they can even vary according to the authors, disciplines, periods and contexts. As a consequence, there is no town, but towns; no city, but cities. The issue of a definition is also the evaluation of theories, in …

The ecogenetic link between demography and evolution: can we bridge the gap between theory and data?

2007

Calls to understand the links between ecology and evolution have been common for decades. Population dynamics, i.e. the demographic changes in populations, arise from life history decisions of individuals and thus are a product of selection, and selection, on the contrary, can be modified by such dynamical properties of the population as density and stability. It follows that generating predictions and testing them correctly requires considering this ecogenetic feedback loop whenever traits have demographic consequences, mediated via density dependence (or frequency dependence). This is not an easy challenge, and arguably theory has advanced at a greater pace than empirical research. Howeve…

Drivers of shell growth of the bivalve, Callista chione (L. 1758) - Combined it environmental and biological factors

2018

WOS:000426027100014; Seasonal shell growth patterns were analyzed using the stable oxygen and carbon isotope values of live-collected specimens of the bivalve Callista chione from two sites in the Adriatic Sea (Pag and Cetina, Croatia). Micromilling was performed on the shell surface of three shells per site and shell oxygen isotopes of the powder samples were measured. The timing and rate of seasonal shell growth was determined by aligning the delta O-18(shell)-derived temperatures so that the best fit was achieved with the instrumental temperature curve. According to the data, shells grew only at very low rates or not at all during the winter months, i.e., between January and March. Shell…

Growth patterns and life-history strategies in Placodontia (Diapsida: Sauropterygia)

2015

Placodontia is a clade of durophagous, near shore marine reptiles from Triassic sediments of modern-day Europe, Middle East and China. Although much is known about their primary anatomy and palaeoecology, relatively little has been published regarding their life history, i.e. ageing, maturation and growth. Here, growth records derived from long bone histological data of placodont individuals are described and modelled to assess placodont growth and life-history strategies. Growth modelling methods are used to confirm traits documented in the growth record (age at onset of sexual maturity, age when asymptotic length was achieved, age at death, maximum longevity) and also to estimate undocum…

Flore turonienne des silex fossilifères de Châtellerault (Ouest de la France)

2018

International audience; Three new localities yielding fossiliferous flints are reported from the Châtellerault area (Vienne, western France). They include one archaeological site (La Grande Vallée) and two zones with alterite deposits (L’Aunas and Les Bariollières). Broken surfaces of flint nodules show co-occurrence of marine invertebrates such as bryozoans, echinoids (Micraster Agassiz, Orthopsis Cotteau), gastropods (Acteonella d’Orbigny), rudists, and sponges. The association of Acteonella, Micraster and Orthopsis confirms the Turonian age (Upper Cretaceous) of the fossil assemblage. The marine invertebrates co-occur with plant macroremains including fragments of conifer leafy axes such…
