Reflections on the Other Side. A Southern Iberia Origin for the First Pottery Production of Northern Morocco?

2021

Archaeological works in Morocco (the Spanish-Moroccan team) were funded by a European Research Council Advanced Grant AGRIWESTMED (Origins and spread of agriculture in the western Mediterranean region) coordinated by L.P.-CH. Processing works were performed thanks to a IJCI-2016-27812 -Spanish Ministry of Science, Innovation and Universities-Universidad de Granada, Juan de la Cierva-Incorporacion Agreement (2016, by RMMS), and by funding provided in the framework of project "Archaeobiology of the Neolithic of the Southern Iberian Peninsula" (NeArqBioSI) A-HUM-460-UGR18 by Consejeria de Economia, Conocimiento, Empresas y Universidad.

Reply to Douka et al: Critical evaluation of the Ksâr 'Akil chronologies

2015

Our paper (1) proposes a new chronology for Ksâr 'Akil based on 16 accelerator mass spectrometry (AMS) determinations on shells. To minimize the possibility of dating diagenetically compromised samples, we conducted amino acid racemization analyses on the intracrystalline proteins, oxygen isotope analysis, and geochemical characterization of all dated shells. Our calibrated radiocarbon ages fit well with existing Levantine chronologies, but are up to 4,000 y older than Douka et al.’s (2). Our paper explores several possibilities for this difference, whereas Douka et al. (3) provide alternative explanations. They accept our radiocarbon ages as correct but question our sample selection and Ba…

New insights into the neolithisation process in southwest Europe according to spatial density analysis from calibrated radiocarbon dates

2017

The agricultural way of life spreads throughout Europe via two main routes: the Danube corridor and the Mediterranean basin. Current archaeological literature describes the arrival to the Western Mediterranean as a rapid process which involves both demic and cultural models, and in this regard, the dispersal movement has been investigated using mathematical models, where the key factors are time and space. In this work, we have created a compilation of all available radiocarbon dates for the whole of Iberia, in order to draw a chronological series of maps to illustrate temporal and spatial patterns in the neolithisation process. The maps were prepared by calculating the calibrated 14C date …

Towards a dendrochronologically refined date of the Laacher See eruption around 13,000 years ago

2020

Highlights • Previous age estimates of the Laacher See Eruptions (LSE) around 12,900 years are still diverging and imprecise. • The combination of dendrochronology, wood anatomy, and 14C measurements holds the potential to establish a precise LSE date. • An absolute calendric date of the LSE would improve the synchronization of European Late Glacial to Holocene archives. Abstract The precise date of the Laacher See eruption (LSE), central Europe’s largest Late Pleistocene volcanic event that occurred around 13,000 years ago, is still unknown. Here, we outline the potential of combined high-resolution dendrochronological, wood anatomical and radiocarbon (14C) measurements, to refine the age …

Luminescence Dating of Fluvial Deposits in the Rock Shelter of Cueva Antón, Spain

2015

Abstract The fluvial sediments at Cueva Antón, a Middle Palaeolithic rock shelter located in the valley of the River Mula (Southeast Spain), produced abundant lithic assemblages of Mousterian affinities. Radiocarbon dates are available for the upper part of the archaeological succession, while for the middle to lower parts chronometric data have been missing. Here we present luminescence dating results for these parts of the succession. Quartz OSL on small aliquots and single grain measurements yield ages ranging from 69 ± 7 ka to 82 ± 8 ka with a weighted mean of 72 ± 4 ka for sub-complexes AS2 to AS5. Equivalent dose estimates from large aliquots were highest and inconsistent with those f…

The triumphal cross of the cathedral of Nevers: painting technique and examination

2019

The large polychrome wooden cross preserved in the Saint-Cyr et Sainte-Julitte cathedral in Nevers was badly damaged during the bombing in July 1944. Restored and put on display on a modern cross in front of the choir, the sculpture suffered a new fall in 2015. The conservation of the work, directed by DRAC-CRMH of Burgundy-Franche-Comté, was preceded by a phase of technical study. Micro-stratigraphic, taxonomic and radiometric analyses and the dendrochronology of the cross were carried out. The dendrochronology of the cross of Nevers and the comparison with radiocarbon dating place the elaboration of the work in the last quarter of the 12th century while confirming the contemporaneousness …

A mediterranean perspective of the neolithization process. The cave of Nerja in the context of andalusia (Spain)

2013

[EN] This paper offers an overview for the Early Neolithic of the southern coast of Andalusia (Spain). Analyses of materials recovered during the 1979-87 excavations in Nerja cave by professor Francisco Jordá Cerdá, including new radiocarbon dates on domestic taxa, allow us to examine the Mesolithic-Neolithic transition. Paleoenvironmental and paleoeconomic data (stratigraphy and bioarcheological data) combined with archaeological data (ornaments, bone tools, lithics, and ceramics were analysed) to provide a regional perspective on the neolithisation of the western Mediterranean. There is an apparent 500-year gap between occupations by the last coastal foragers and the earliest Neolithic fa…

Combined spatial Radiocarbon density maps and refined SCPD method to explore food production spread through the central and western mediterranean

2018

The neolithisation process in Europe constitutes a fundamental issue of interest in social evolutionary studies. The pioneer work of Ammerman and Cavalli-Sforza (1984) has been considered the basis for discussing the mechanisms involved in the expansion of farming and herding practices in a continental scale, assuming their spread from the Near East domestic core area. From an evolutionary perspective the introduction of agriculture and livestock implies major shifts in social dynamics including changes in demographic patterns as well as in settlement distribution and cultural models. Spatial analysis together with the use of radiocarbon data as a demographic proxy maybe one of the keys to …
