An anthracological approach to understanding Late Classic period cultural collapse in Mesoamerica’s northwestern frontier

2012

International audience; For over 50 years, researchers have suggested that increased regional rainfall over the highland deserts of Mesoamerica's northwestern frontier zone during the Classic period (AD 200-900) allowed for the colonization of the zone by farming groups who originated from Central and/or West Mexico. A severe and prolonged drought is hypothesized to have later provoked the abandonment of the region by these sedentary populations by AD 900. However, very little research has been carried out in the zone to detect evidence of this proposed climate change. I present results from the first systematic study of wood charcoal from the northwestern frontier, comparing the data from …

Vineyard soil mapping from very high spatial resolution images in hillslope context: a contribution of terroir knowledge.

2014

The Burgundian vineyard hillslopes (Côte-d’Or, France) exhibit a high diversity of soils resulting from the combination of several natural and anthropogenic factors acting at various spatio-temporal scales. The soil types have major role in viticulture, since they partly determine wine-growing quality. However, soil undergoes important degradation caused by hydric erosion and vineyard management practices. To control this soil heritage for a sustained viticulture in Côte-d’Or, a better knowledge of soil is necessary. The objectives of this work is to characterise vineyard soils and to identify the factors governing their diversity using an interdisciplinary approach crossing geology, geomor…

: Quantification of the morphological evolution of the Hominid skull and heterochronies

1998

Comparisons of adult skulls of various species of great apes, fossil hominids and modem humans in the sagittal, Francfort and ortho-sagittal planes reveal a series of three separate organisation plans: 'GreatApe', 'Australopithecine'and 'Homo', tbe latter including primitive men (Homo ergaster-erectus-neandertalensis) and modern humans (Homo sapiens). Morphological changes between these plans are quantified for the first time here by vector fields. This study confirms the existence of cranio-facial contraction, which occurs as a series of leaps. The juvenile morphology of the great ape skull is broadly preserved in adult Homo sapiens, suggesting that numerous heterochronies have occurred in…

Some European Bronze Age objects were produced by what has been described as serial metalworking. One particularexample is the Middle Bronze Age palstave, massively produced and used in Western Europe during the mid-second millennium BC.These artefacts were often voluntarily buried together in hoards, meaning they were removed from the production network, thus avoidingany recycling. They are found intact, either as rough castings or ready for use. These homogeneous objects are grouped in sets of severalitems, or in tens, or even in hundreds. Such discoveries have immediately led to numerous questions as to the possible interpretation ofthis behaviour. It is clear that prehistoric craftsmen …

Aux sources de la Douix : objets et dépôts métalliques en milieu aquatique au Premier âge du Fer en France à partir de l’exemple d’un site remarquable

2015

International audience; Les eaux de la Douix (Châtillon-sur-Seine) ont livré un ensemble de fibules en fer et en alliage cuivreux qui n’a que peu d’équivalent dans l’ensemble des dépôts en milieu aquatique connus en France au Premier âge du Fer. Découvert à la fin des années 1990 dans une résurgence, ce dépôt regroupe surtout des fibules, qui se trouvent ici exceptionnellement réunies alors qu’elles sont plutôt découvertes de façon isolée dans les habitats et les sépultures. Dans le cadre de cet article, nous nous proposons d’en faire une présentation détaillée (à travers une approche quantitative et qualitative). En abordant plus spécifiquement la chronologie et les types d’assemblages qui…

Noyen-sur-Seine (Seine-et-Marne), Nord du Bois du Chêne, Caille-Boton, La Chapotte et Le Haut du Faÿ : phase 2 : rapport de diagnostic

2011

Ce diagnostic se situe sur la commune de Noyen-sur-Seine, sur une carrière d'exploitation de granulats. Il a permis la mise au jour de structures du Campaniforme au Nord-Est du site, de l'étape moyenne du Bronze final (culture Rhin-Suisse-France orientale) et du Hallsatt D2/3-La Tène A. Les structures de la culture RSFO sont en continuité avec celles mises au jour lors du diagnostic sur la parcelle adjacente (Samzun, 2009), et qui ont donné lieu à une fouille durant l'été 2010 (Nallier, à paraître). Les structures du Hallstatt sont apparues au Nord-ouest du décapage.

L'habitat néolithique récent de Geispolsheim "Forlen" (Bas-Rhin) : contribution à la périodisation de la culture de Munzingen et à l'étude de ses rel…

2011

The recent Neolithic site of Forlen in Geispolsheim, attributed to the recent Munzingen, has yielded a series of enclosures containing ceramic forms unprecedented in the context of Munzingen B. We have detected the influence of late productions by the Pfyn culture and propose the identification of a new stage in the recent Munzingen, which we have unoriginally named Munzingen C, and is typified by the appearance of ceramic forms with rounded profiles. This episode may date from around 3650-3550 BC, a late dating that has been confirmed by two carbon 14 tests. The discovery allows a strong claim to be made that ancient trading networks that linked the Rhine Valley with the Swiss Plateau and …
