Observaciones sobre algunos criterios tafonómicos usados en la interpretación de asociaciones malacológicas fósiles.
1984
In the present paper a revision of some taphonomic criteria commonly used in the interpretation of fossil mollusca assemblages is realized . The field work on living and death assemblages of mollusca in a shallow muddy bottom has been carried out in the coast near Denia (Alicante, Spain). Although the supposed lineal relation between specific abundance and probability of autochthony could explain the structure of part of the considered assemblages, in other a clear disagreement due to a massive incursion of youth elements in observed . By other hand, the possibility of horizontal transport not detectable by these means (anonymous alochtonic fluxes) imposes another limitation to the pretende…
The beginning of the Neolithic in Nerja cave and la Cova de la Sarsa. Archaeological context and radiocarbon dating
2018
Las dataciones radiocarbónicas resultan una herramienta útil para establecer el marco cronológicode los contextos arqueológicos, aunque en ocasiones el adjetivo de «absoluto» se convierte en una categoría. En el caso del Neolítico antiguo, la selección de muestras singulares de vida corta de especies domésticas o restos de Homo sapiens en contextos neolíticos pretendía definir con mayor precisión la cronología de los momentos iniciales de su llegada a la península ibérica. Los casos documentados en las cuevas de Nerja y Sarsa son un buen ejemplo del debate que generan sus resultados, la problemática de sus secuencias y el contexto de discusión regional. Se muestran los resultados tras la va…
The role of fire within Neolithic collective burials: Spatial analyses of cremains from the site of La Truie Pendue, France
2016
International audience; The use of collective graves is one of the main features of the western European Late Neolithic. A single gravesite received the successive deposition of dozens or sometimes hundreds of individuals. While cremations or even full-fired inhumation layers are often found within these funerary deposits, the actual role of fire is still poorly understood. Recently discovered within the important archaeological complex of Passy (Yonne, France), the burned collective grave of La Truie-Pendue provides an outstanding case study to examine the use of fire within Neolithic funerary rites. In this study, we develop a new contextual approach to bone alterations in order to recons…
Neanderthal subsistence and short-term human occupation patterns during MIS 5. New data from Abrigo de la Quebrada (Valencia, Spain)
2019
Abstract Abrigo de la Quebrada (Chelva, Valencia) is a Middle Palaeolithic site with Neanderthal occupations, composed by nine archaeological levels that extend from MIS 3–5 in the upper levels (II-V), up to MIS 5 in the lower levels (VI-IX), with dates for level VI of 80.0 ± 4.7 ky and 83.2 ± 5.4 ka. Level IV show short and repeated human occupations, with a high density of materials related to hunting activities focus on several ungulates as ibex, equids and cervids. However, the lower levels (VII, VIII and IX) respond to different sedimentation rates and occupations. Archaeozoological and taphonomic studies show mixed occupations. Raptors or small carnivores seem to be responsible of the…
Neanderthal firewood management: Evidence from Stratigraphic Unit IV of Abric del Pastor (Eastern Iberia)
2015
This paper presents anthracological data from Abric del Pastor (Alcoi, Spain), a Middle Paleolithic rock shelter site. Analysis of 1077 wood charcoal remains from Stratigraphic Unit IV (S.U. IV), collected within archaeological combustion structures and from loose sediment outside of structures, allowed us to characterise the local landscape, as well as to approach the interaction between Neanderthal groups and their local environment. Taxonomic identification suggests that firewood was gathered from nearby sources, with predominance of juniper (Juniperus sp.) followed by thermophilous shrubby taxa. Additional analysis focussing on post-depositional processes affecting charcoal have shown f…
Presence of the genus Cuon in upper Pleistocene and initial Holocene sites of the Iberian Peninsula: new remains identified in archaeological context…
2010
The dhole (Cuon alpinus) has been documented on the Iberian Peninsula throughout the Middle and Upper Pleistocene in archaeological and palaeontological contexts. However, this is an uncommon species among the Iberian quaternary faunae as a whole. This paper focuses on the remains of the genus Cuon recovered in three different sites of the Iberian Mediterranean region and their morphological and osteometrical study. By comparing these with fourteen complete skeletons of Canis lupus, as well as with other remains of C. alpinus, we intend to highlight some anatomical and metrical differences between Cuon and Canis that, added to those already published, could be a functional base-line for the…
The Quaternary fossil record of the genus Testudo in the Iberian Peninsula. Archaeological implications and diachronic distribution in the western Me…
2009
This paper explores the presence of tortoise remains and its meaning in Palaeolithic archaeological contexts. We focus on two topics: (1) the presence or absence of the genus Testudo from the Early Pleistocene to the Holocene in SW Europe; and (2) the relationship between Testudo and the palaeoclimatic and palaeoenvironmental conditions diachronically. In order to address this objective, we collected published and unpublished data from different sites on the eastern Iberian Peninsula. The results obtained by this study demonstrate that Testudo hermanni was the only tortoise present in this area until recent times and its presence in archaeological sites is almost always related to anthropic…
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 …
Preservation and decay of plant remains in two Palaeolithic sites: Abrigo de la Quebrada and Cova de les Cendres (Eastern Spain). What information ca…
2020
Abstract Plant remains are quickly affected by post-depositional processes once they are deposited in archaeological sites. In normal conditions, decomposing organisms cause their decay and final disappearance unless a preservation agent, as carbonisation or mineralisation, inhibit their activity. Moreover, physical and chemical processes could also lead to the partial or total destruction of the archaeobotanical assemblage. Thus, an analysis of their characteristics is useful for an assessing of the taphonomic processes. Archaeobotanical assemblages from two Palaeolithic sites, Abrigo de la Quebrada and Cova de les Cendres, have been analysed in terms of taxonomic composition of the assemb…
Climate variation during the Holocene influenced the skeletal properties of Chamelea gallina shells in the North Adriatic Sea (Italy)
2021
Understanding how marine taxa will respond to near-future climate changes is one of the main challenges for management of coastal ecosystem services. Ecological studies that investigate relationships between the environment and shell properties of commercially important marine species are commonly restricted to latitudinal gradients or small-scale laboratory experiments. This paper aimed to explore the variations in shell features and growth of the edible bivalve Chamelea gallina from the Holocene sedimentary succession to present-day thanatocoenosis of the Po Plain-Adriatic Sea system (Italy). Comparing the Holocene sub-fossil record to modern thanatocoenoses allowed obtaining an insight o…
