Ocre, hematites y óxido de hierro: el problema terminológico = Ochre, Hematite and Iron Oxid: The Terminological Issue

2016

Los óxidos de hierro son prácticamente omnipresentes al analizar contextos, no solo referentes al arte rupestre, sino también en relación con toda una serie de actividades que podríamos considerar cotidianas en ambientes prehistóricos. Sin embargo, su estudio sistemático no ha comenzado hasta tiempos muy recientes. Fruto de ello, podría decirse que una parte de la literatura arqueológica no especializada en el campo de la pigmentología muestra, en ocasiones, cierta inexactitud terminológica. Con este documento pretendemos, a través de un análisis tanto de su funcionamiento, como de las propiedades geoquímicas y mineralógicas del ocre, la hematites y los propios óxidos de hierro, exponer la …

Introduction. Leave no stone unturned: Perspectives on ground stone artefact research

2016

Ground stone tools served in many physical and social contexts through millennia, reflecting a wide variety of functions. Although ground stone tool studies were neglected for much of early archaeology, the last few decades witnessed a notable international uptick in the way archaeologists confront this multifaceted topic. Today, with the advance of archaeology as a discipline, research into ground stone artefacts is moving into a new phase that integrates high resolution documentation with new methodological, analytical techniques, and technological approaches. These open new vistas for an array of studies and wide-ranging interpretive endeavours related to understanding ground stone tool …

Estimating “land use heritage” to model changes in archaeological settlement patterns

2016

International audience; In this paper, we present a method to calculate a “land use heritage map” based on the concept of “memory of landscape”. Such a map can be seen as one variable among others influencing site location preference, and can be used as input for predictive models. The computed values equate to an index of long-term land use intensity. We will first discuss the method used for creating the land use heritage map, for which kernel density estimates are used.We will then present the use of these land use heritage maps for site location analysis in two study areas in SE France. Earlier analyses showed that the influence of the natural environment on settlement location choice i…

Antropologia come "general Weltkenntniß" Kant e la concezione cosmica dell'umano

2018

Il progetto antropologico di un mondo-ambiente nel quale l'uomo, grazie allo sviluppo delle proprie capacità, trova la sua posizione e conquista un ruolo centrale, si inserisce, in Kant, all'interno in un disegno più ampio che pone l'uomo al cospetto di scopi la cui realizzazione va ben al di là di quel che egli può fare; va ben al di là dell'immagine pragmatica di un mondo pensato e progettato a misura d'uomo. Come risulta insufficiente, dunque, ogni antropologia fisiologica che rimanga limitata al punto di vista dell'uomo in quanto prodotto del gioco della natura, altrettanto insufficiente risulterebbe un'antropologia pragmatica che si legasse unicamente alla rappresentazione antropocentr…

Carbon, nitrogen and oxygen isotope fractionation during food cooking: Implications for the interpretation of the fossil human record.

2017

13 pages; International audience; ObjectivesStable isotope data provide insight into the reconstruction of ancient human diet. However, cooking may alter the original stable isotope compositions of food due to losses and modifications of biochemical and water components.MethodsTo address this issue, carbon, nitrogen and oxygen isotope ratios were measured on meat aliquots sampled from various animals such as pork, beef, duck and chicken, and also from the flesh of fishes such as salmon, European seabass, European pilchard, sole, gilt-head bream, and tuna. For each specimen, three pieces were cooked according to the three most commonly-known cooking practices: boiling, frying and roasting on…

Bone diagenesis in arid environments; An intra-skeletal approach

2014

Bone trace element content and isotopic composition are closely related to human nutrition. The investigation of archaeological bone geochemistry can help us to better understand the relationship between past populations and their environment alongside cultural practices as inferred from dietary reconstruction. However, dietary in- formation may be altered post-mortem by diagenetic processes in soil. In this study, bone mineralogy (Ca/P, sec- ondary minerals, organic matter content and bone apatite crystallinity), histology, element content (Mg, Na, F, Sr, Ba, Mn, Fe, La, Ce and U) and stable isotope composition (δ13Candδ18O carbonate) were investigated at the intra- individual scale in ord…

Dental calculus indicates widespread plant use within the stable Neanderthal dietary niche.

2018

The ecology of Neanderthals is a pressing question in the study of hominin evolution. Diet appears to have played a prominent role in their adaptation to Eurasia. Based on isotope and zooarchaeological studies, Neanderthal diet has been reconstructed as heavily meat-based and generally similar across different environments. This image persists, despite recent studies suggesting more plant use and more variation. However, we have only a fragmentary picture of their dietary ecology, and how it may have varied among habitats, because we lack broad and environmentally representative information about their use of plants and other foods. To address the problem, we examined the plant microremains…
