Fauna e industria en materia dura de origen animal del lugar sagrado de la Cultura de las Motillas: Castillejo del Bonete (Terrinches, Ciudad Real)
2020
En los últimos años revistas científicas han publicado diversos estudios (cerámica, metal, material lítico, etc.) sobre Castillejo del Bonete. Este trabajo presenta datos inéditos sobre la industria ósea, micro y macromamíferos encontrados en este yacimiento. La industria elaborada sobre materia dura de origen animal está constituida principalmente por piezas elaboradas con hueso, asta o dientes, que fueron utilizados como medios de producción o complementos para vestir y adornar a los difuntos, o tallar ídolos. El estudio de los micromamíferos aporta información sobre el final del uso de estos túmulos, así como sobre aspectos ambientales. Los perfiles de mortalidad de los grandes mamíferos…
Ancient DNA provides no evidence for independent domestication of cattle in Mesolithic Rosenhof, Northern Germany
2008
Abstract Recent studies of modern and ancient mtDNA in domesticated and wild cattle has indicated that members of the extinct Near Eastern aurochs population (Bos primigenius primigenius) were the wild progenitors of European domesticated cattle (Bos taurus) (Bollongino, R., Edwards, C.J., Burger, J., Alt, K.W., Bradley, D.G., 2006. Early history of European domestic cattle as revealed by ancient DNA. Biol. Lett. 2, 155–159; Edwards, C.J., Bollongino, R., Scheu, A., Chamberlain, A., Tresset, A., Vigne, J.-D., Baird, J.F., Larson, G., Ho, S.Y.W., Heupink, T.H., Shapiro, B., Freeman, A.R., Thomas, M.G., Arbogast, R.-M., Arndt, B., Bartosiewicz, L., Benecke, N., Budja, M., Chaix, L., Choyke, A…
An integrated program of geophysical survey, coring, and test excavations to study a 4th millennium bc-cal ditch at Alt del Punxó (Muro de L’alcoi, A…
2008
The potentially long and interesting archaeological sequence revealed by systematic survey at the site of Alt Del Punxó (Muro de l’Alcoi, Alacant) was the basis for initiating a study of the locality’s subsurface structures using new methods of remote sensing. Geophysical survey (magnetometry and tomography) and systematic augering revealed buried structures, including monumental earthworks, and guided subsequent excavations to collect more detailed data about the nature and age of these prehistoric features. The information recovered, including new radiocarbon dates, offers a new perspective on the organization of prehistoric populations in this region of south-central Valencia since the b…
Osteological and paleodietary investigation of burials from Cova de la Pastora, Alicante, Spain
2011
We present results of osteological and isotopic analyses of human remains from Cova de la Pastora (Alcoi, Alicante, Spain) and discuss the implications in light of a new sequence of radiocarbon dates indicating that the cave was used as a burial site in the Late Neolithic (ca. 3800e3000 cal BC), Chalcolithic (ca. 3000 e2500 cal BC), Bell Beaker Transition (Horizonte Campaniforme Transicional - HCT; ca. 2500e2200 cal BC) and the Bronze Age (ca. 2200e1500 cal BC). Similarities in stable isotopic values of C and N indicate little variation in subsistence between men and women, and a similar nutritional base from the Late Neolithic to the Bronze Age. This pattern of stability is augmented by ev…
From pedologic indications to archaeological reconstruction: deciphering land use in the Islamic period in the Baida district (north-western Sicily)
2013
Abstract The aim of this work was to detect imprints on soil properties from former Islamic land use (9th to 11th century) using a multi-method, soil-chemical approach. Four soil profiles (with buried horizons) found in the vicinities of former Islamic settlements in Sicily were analysed for phosphorus (total, organic and inorganic), nitrogen (total, NO 3 − and NH 4 + ), carbon compounds (δ 13 C, lipids, polycyclic aromatic hydrocarbons (PAH) and functional groups), physical and chemical C-fractions and the state of soil weathering. Two soil profiles contained ceramic sherds from the Islamic period. Inorganic nitrogen forms, phosphorous and the PAH content indicated strong impacts from trad…
From sepulchre to butchery-cooking: Facies analysis, taphonomy and stratigraphy of the Upper Palaeolithic post burial layer from the San Teodoro Cave…
2020
Abstract The San Teodoro Cave is considered the most significant witness of the first, Epigravettian, human colonization of Sicily from the Italian continent. Furthermore the site is a paradigmatic horizon in the Pleistocene faunal record, demonstrating a progressive transition from mega faunas to smaller-sized, Boreal, faunas. The site has been repeatedly studied and excavated, with different aims and approaches, leading to an interpretation of Epigravettian burial site and daily attendance. Here we propose a reappraisal of the study of the stratigraphy of the site, and in particular of the bone-rich layer (PAL) accumulated over the red ochre layer that apparently sealed all the different …
Antiguas excavaciones, nuevas respuestas. El yacimiento epimagdaleniense de la Cova del Clot de l'Hospital (Roquetes, Baix Ebre)
2015
El objetivo de este trabajo ha sido estudiar los materiales obtenidos con las excavaciones de Francesc Esteve Gálvez en la Cova del Clot de l’Hospital (Bajo Ebro), yacimiento de finales del Pleistoceno-inicios del Holoceno, descubierto por él mismo el año 1945. La representación de raspadores, truncaduras, buriles y laminitas de dorso, entre otros tipos, permite atribuirlo al Epimagdaleniense, atribución corroborada por dos fechas radiocarbónicas sobre huesos de fauna: 11.115 y 10.045 BP. De esta forma, este yacimiento se suma a un numeroso conjunto de yacimientos del período citado, conocidos en las provincias de Tarragona y de Castellón de la Plana. Así mismo, el estudio de los restos fau…
Mid-Holocene vegetation dynamics in the Tejo River estuary based on palaeobotanical records from Ponta da Passadeira (Barreiro-Setúbal, Portugal)
2014
This paper presents the results of pollen and charcoal analyses carried out in the sedimentary formation of Ponta da Passadeira, south of the Tejo River estuary, Portugal. The data provide information regarding the evolution of the coastline and ecosystem of the estuary during the mid and late Holocene. The study focuses on a group of upright woody fossilized tree remains that, together with those identified earlier by Garcia-Amorena et al. (2007), form part of the fossil forest of Ponta da Passadeira. Eight remains were identified as Pinus pinaster, four as Pinus pinea and one as Pinus sp. Two specimens of these species were dated to 6523 and 5805 cal. a BP. Pollen analysis was undertaken …
Astrochronology of the Valanginian stage from GSSP candidates and hypostratotype.
2013
Valanginian; Astrochronology; Gamma-ray spectrometry; Weissert event; Paraná-Etendeka; International audience; The Valanginian Stage currently displays no radiometric age, which severely hampers palaeoceanographic reconstructions for this time interval. An astrochronology of the Valanginian Stage using the stable 405-kyr eccentricity cycle was performed on biostratigraphically well-calibrated standard sections from the Vocontian Basin (southeastern France). High-resolution gamma-ray spectrometry signals were obtained from orbitally driven marl-limestone alternations from five sections in the basin, and they display the same long-term trends. The spectral analyses present the pervasive recor…
Tethyan magnetostratigraphy from Pizzo Mondello (Sicily) and correlation to the Late Triassic Newark astrochronological polarity time scale
2004
We present the magnetostratigraphy and stable isotope stratigraphy from an expanded (~430-m-thick) Upper Triassic marine limestone section at Pizzo Mondello, Sicily, and review published biostratigraphic information that can be used to defi ne the location of the conodont Carnian-Norian and Norian- Rhaetian boundaries in this section. Pizzo Mondello offers good potential for magnetostratigraphic correlation of marine biostratigraphic and chemostratigraphic data with the continental Newark astrochronological polarity time scale (APTS) for development of an integrated Late Triassic time scale. The relatively stable average values of 18O centered on 0‰ are a strong indication that the Cherty …
