Inproceedings Reference audio/x-realaudio Reconstructing the Palaeo-Environment of the Ancient City of Charax Spasinou
From its foundation to its heydays as trading hub and to its final abandonment, the history of Charax Spasinou was intimately connected with the evolution of the river systems of the southernmost part of the Mesopotamian plain and the shoreline of the Persian Gulf. This ongoing research, which is part of the Charax Spasinou Project of the Universities of Konstanz and Manchester supported by the German Research Foundation and the Culture Protection Fund of the British Council, aims to reconstruct the evolution of the landscape and palaeoenvironment around the capital of Mesene, by combining evidence from remote sensing data and geological coring. Here, results from the analysis of satellite imagery and a preliminary field campaign carried out in 2018 will be presented. It will be demonstrated that a combined geological and archaeological survey in the wider hinterland of Charax allows an accurate reconstruction of the ancient watercourses and the landscape of Mesene, in which the capital was the nodal point for nearly a millennium.

Article Reference Reconstruction et analyse biomécanique du Neandertal « Spy II » en utilisant le logiciel lhpFusionBox
En 1886, la mise au jour de deux squelettes néandertaliens dans les sédiments de la terrasse de la grotte de Spy, en Belgique, fut une découverte majeure. Une étude pluridisciplinaire des fossiles a permis la découverte de nouveaux ossements néandertaliens qui appartiennent au squelette nommé « Spy II ». Bien que partiel, le squelette de Spy II est un de plus complets trouvés à ce jour ; il a donc servi dans cette étude comme de base à la reconstitution d’un squelette néandertalien virtuel. Les éléments osseux provenaient des fossiles Kebara 2 pour le bassin (en provenance d’Israël) et Neandertal 1 pour le fémur (Allemagne). Ces fossiles complémentaires présentaient des dimensions différentes de celles de Spy II. Afin de mettre ces ossements à l’échelle de Spy II, le logiciel lhpFusionBox, développé au LABO, a été amélioré afin de permettre des remises à l’échelle par utilisation d’os différents (en général, une telle remise à l’échelle se fait en utilisant des os homologues). L’utilisation de ces outils a permis l’obtention d’un modèle de membres inférieurs aussi proche que possible des dimensions et proportions du spécimen Spy II. Le modèle de membres inférieurs ainsi acquis a ensuite été augmenté d’une estimation des lignes d’actions de muscles ischio-jambiers. Enfin, ce dernier modèle a été fusionné avec un jeu de données cinématiques collectées sur un volontaire. Ceci a permis d’estimer le bras de levier des muscles reconstitués et de déterminer si les surfaces articulaires du modèle de Néandertalien est compatible avec la cinématique moderne. Les résultats semblent démontrer que les articulations des membres inférieurs des Néandertaliens était conciliable avec les mouvements de l’Homo Sapiens. Par contre, les estimations quantifiées des bras de levier musculaires du Néandertalien étaient plus élevés que ceux l’homme moderne. Ceci présente évidement un avantage mécanique conférant un plus grand moment musculaire. Plus récemment, le squelette a été entièrement reconstitué. Les modèles 3D virtuels des os ont ensuite été imprimés en 3D en taille réelle. Ces os ont servis de base à une reconstitution artistique hyperréaliste de l’Homme de Spy, visible à l’Espace de l’Homme de Spy à Onoz (province de Namur, Belgique).

Inproceedings Reference Reconstruction of environmental and climatic changes during the Late Glacial at Moerbeke (Flemish Valley, Belgium) using multiproxy lake sediment analyses
The Flemish Valley (NW Belgium) is a relatively flat and low-lying area situated at the southern limit of the lowland cover sand region of the NW European plain. During the Late Pleniglacial and the Late Glacial, numerous shallow lakes were formed. These depressions are important and sensitive ecosystems providing excellent continental archives to investigate past environmental changes since the last glaciation, making this area of particular interest. However, although previous pollen analyses have punctually been carried out in the Flemish Valley, studies employed in combination with other proxy records are rare, and temporal resolutions stay low and not suited to catch abrupt and short changes as climatic crises may be. In order to better understand the natural processes which occurred in these particular ecosystems, an integrated research program based on a multiproxy approach has recently been undertaken on the Late Glacial. The fundamental aim is to produce a detailed and quantified reconstruction of past environments at high temporal resolution in relation with climate variability by means of independent proxies. For that purpose a 70m long trench was dug at Moerbeke through the deepest part of the Moervaart Depression, one of the largest palaeolake of Europe. Several sequences revealing a contrasted stratigraphy (lake marl, gyttja, peaty deposits and sandy layers alternating) are investigated using biological indicators (pollen, NPPs, plant macrofossils, charcoal, diatoms, ostracods, mollusks, insects), sedimentological (LOI, magnetic susceptibility, granulometry, gamma-density), chronological (AMS 14C and OSL dating, tephra layers) and geochemical proxies (isotopes). Using multiproxy comparisons, we will try to assess if the vegetation and other environmental indicators have changed concomitantly and simultaneously and to decipher between the most sensitive palaeoenvironmental indicators to regional climatic conditions.
