Late Quaternary coastal uplift of southwestern Sicily, central Mediterranean sea
2021
Abstract Mapping and luminescence aging of raised marine terraces and aeolian ridges along an ∼90 km coastal stretch in southwestern Sicily provide the first quantitative assessment of vertical tectonic deformation in this region, which spans the frontal part of an active thrust belt. We recognized a staircase of eleven terraces and nine related aeolian ridges. The elevation profile of terraces parallel to the coast shows a >90 km long bell-shaped pattern, onto which shorter-wavelength (∼10 km long) undulations are superimposed. Luminescence ages from terraced beach deposits and aeolian sediments constrain the position of paleoshorelines formed during MIS 5e, 7a and 7c, with a maximum uplif…
Earliest evidence of Neolithic collective burials from Eastern Iberia: Radiocarbon dating at the archaeolgoical site of Les Llometes (Alicante, Spain)
2016
AbstractIn the Valencia region of Spain, the dominant use of natural caves for collective burials during the Late Neolithic and Chalcolithic periods has been documented. Collective burials are central to the hypothesis about social relationships in Copper Age societies from Iberia, and key to interpreting kinship-based societies. Les Llometes (Alcoi, Alicante) is one of the biggest collective burial sites existing in eastern Iberia. This article presents the direct14C dates on 25 skeletal remains at the site. The results indicate that the site was used as a burial place from the end of the 5th millennium cal BC until the end of the 4th millennium cal BC, and is a first milestone for future …
El yacimiento calcolítico de Karea en el contexto de las cuevas sepulcrales de Gipuzkoa (País Vasco)
2018
En el yacimiento arqueológico de Karea (Aia, Gipuzkoa), integrado por las cavidades contiguas de Karea-A y Karea-B, se recuperaron numerosos restos cerámicos y faunísticos (Karea-A) y vestigios de una inhumación calcolítica (Karea-B). El presente trabajo se ha vertebrado en dos ejes. En primer lugar, el estudio de ambos depósitos mediante diferentes disciplinas: (1) estudio antropológico; (2) estudio del ajuar, compuesto por restos cerámicos y faunísticos; (3) identificación antracológica de los restos leñosos recuperados en el depósito funerario y por último, (4) estudios isotópicos que nos han permitido obtener datos de la alimentación (δ13C y δ15N) y procedencia (87Sr/86Sr) del sujeto in…
Mobility across the pre-Pyrenean mountain ranges during the Chalcolithic through strontium isotopes in human enamel: La Cueva de los Cristales (Sarsa…
2020
Abstract There is an increasing abundance in the archaeological record in Iberia for the Late Neolithic and the beginning of the Chalcolithic periods, mostly regarding burials. The higher pre-Pyrenean areas began to be settled more frequently, but the poor weather conditions have led researchers to suggest that human presence mostly took the form of sporadic visits. This argument has provoked substantial controversy given the increase not only in the archaeological artefacts recorded but also in the number of burial sites in less accessible places. To shed more light on the knowledge of these Chalcolithic mountain groups, we have carried out strontium isotope analysis of human enamel of ind…
The lay of land: Strontium isotope variability in the dietary catchment of the Late Iron Age proto-urban settlement of Basel-Gasfabrik, Switzerland
2018
Abstract Basel-Gasfabrik (Switzerland) comprises an extensive La Tene (chiefly Lt D, 150–80 BCE) settlement and two associated cemeteries at which strontium (87Sr/86Sr) isotope analysis of human and animal teeth investigated regional and supra-regional contacts. The interpretation of the analytic data, however, requires information on the isotopic baseline values around the site. Using 102 modern vegetation and 9 water samples from 51 localities, this study characterizes the isotopic ratios of the biologically available strontium of geological units and watercourses around Basel and compares these to 28 human infant, 6 pig, and 5 dog teeth from the site. Furthermore, pedological criteria ev…
Volcanic climate forcing preceding the inception of the Younger Dryas: Implications for tracing the Laacher See eruption
2021
Climatic warming from the last glacial maximum to the current interglacial period was punctuated by a similar to 1300 years long cold period, commonly referred to as the Younger Dryas (YD). Several hypotheses have been proposed for the mechanism triggering the abrupt inception of the YD, including freshwater forcing, an extra-terrestrial impact, and aerosols from volcanic eruptions. Here, we use synchronised sulphate and sulphur records from both Greenland and Antarctic ice cores to reconstruct volcanic forcing between 13,200-12,800 a BPGICC05 (years before 1950 CE on the Greenland Ice Core Chronology 2005; GICC05). This continuous reconstruction of stratospheric sulphur injections highligh…
Images of camels on a mammoth tusk from West Siberia
2020
International audience; This study introduces the engravings on a mammoth tusk from the lower reaches of the Tom River in WestSiberia. The tusk was found in 1988 during construction works and was later transferred to the Tomsk StateUniversity, but it remained almost unknown to specialists until now. Radiocarbon dating by AMS reported theage of the tusk as 13,100–13,005 Сal BP (95% confidence level). The surface of the tusk is engraved with imagesof two-humped camels arranged in two pairs. In addition, arrows and wounds within the contours of the animalscan be seen. The comparative analysis of the stylistic features of the camel figures shows that they correspond tothe age of the tusk itself, …
Climbing into the past—first Himalayan mummies discovered in Nepal
2003
In a cave system in Mebrak (Mustang District, Western Nepal), a team of archaeologists investigating extensive abandoned settlements in the high Himalayas made an extraordinary discovery in 1995. One of the caves had been used as a community burial chamber from ca. 400 BC to 50 AD. Inside, approximately 30 naturally mummified bodies rested in bed-like wooden coffins exhibiting ornamental carving and elaborate painting. The dead had been furnished with a rich store of grave goods consisting of both personal ornaments and objects of daily life as well as the remains of domestic animals. Due to the favourable climatic conditions, all of the artefacts, which also include fur and textile garment…
The first archaeometric characterization of obsidian artifacts from the archaeological site of Samshvilde (South Georgia, Caucasus)
2019
This paper presents the first results about the provenance of obsidian fragments recovered in the archaeological site of Samshvilde (South Georgia, Caucasus) with the aim to obtain knowledge related to the network distribution and procurement of obsidian in Georgia. The geochemical characterization of thirty archaeological finds was obtained by the LA-ICP-MS method, an almost non-destructive technique capable of chemically characterizing the volcanic glass. A comparison of geochemical results obtained on both archaeological artefacts and geological samples collected from Chikiani outcrop in Georgia, together with literature data of southern Caucasus and eastern Turkey, allowed us to define …
Revisiting the Epipalaeolithic-Neolithic Transition in the Extreme NW of Africa : The Latest Results of the Chronological Sequence of the Cave of Kaf…
2021
[EN] This study focuses on the chronostratigraphic sequence of the Cave of Kaf Taht el-Ghar (Dar Ben Karrich, Tétouan, Morocco) excavated in 2012 in the framework of the AGRIWESTMED research project. The broad sequence reveals a series of occupations ranging from the Pleistocene (Moroccan Aterian) to recent historical times. Our research identifies a rich Early Neolithic phase (sixth millennium cal BC) containing the earliest pottery and domesticated animal and plant remains in the western Maghreb. However, this Early Neolithic level is not an immediate successor of the last traces of the Epipalaeolithic hunter-gatherer occupation, which started at the end of the Younger Dryas (10,900–9700 …
