“…The count is based on the fact that each whole macrofossil consists of one specimen. The fragments were also counted and then converted into an estimated integer (minimum number of individuals) using the "méthode au jugé" (Pradat, 2015). All data were recorded in the AGAM database (Schaal, 2019a).…”

By analyzing the mechanisms that govern the interactions between environmental factors and ecosystems, paleoecology refines our knowledge of the mechanisms that are structuring plant communities, helping us to understand the complexity of past environments. While undertaking palaeoecological analyses, it is necessary to analyze and to understand the taphonomic phenomena influencing plant macrofossil assemblages. Indeed, the evaluation of under- and over-representation of taxa makes it possible to judge the interest and quality of the retained data set as a source of paleo-ecological information. The French National Centre for Archaeological Research (CNRA) recommends "refining taphonomic modelling in different aspects: accumulation and modification processes by biological agents, natural ageing processes of taphocenoses" (National Research Programming 2016, p. 35). The inability to reconstruct the diagenetic history of sedimentary layers can sometimes lead to erroneous palaeoecological interpretations. Like all archaeological documents, macrofossil plant assemblages come to us distorted by the taphonomic processes involved in the formation of sediment layers. The study of waterlogged plant macrofossils preserved in the wet sediments of an oxbow lake of the river Meuse (Autrecourt-et-Pourron, Ardennes, France) aims to analyze these taphonomic processes. This archaeobotanical study focusing on a river wall dated to the Preboreal period (11.7 ̵ 10.7 ka BP) allows establishing a taphonomic reference frame. We applied a correspondence analysis to establish links between criteria preservation and the analyzed sediment samples. We observed differences in preservation conditions depending on the stratigraphy and nature of the sediments. Before conducting archaeobotanical studies in natural contexts, an assessment of the taphonomic state of the retrieved plant macrofossils is highly recommended.

“…En conclusion de cette partie sur les nouveaux développements méthodologiques en anthracologie, il convient d'évoquer le programme DENDRAC (Développement d'outils dendrométriques appliqués à l'anthracologie) ( -2015, Dufraisse, Garcia-Martinez, 2011 ;Dufraisse et al, 2018). L'objectif de cette ANR a été de créer des outils et des référentiels adaptés pour travailler sur un matériel particulier car carbonisé, déformé, fragmenté et porteur d'un nombre limité de cernes.…”

“…Les travaux récents des carpologues s'inquiètent également de mieux mesurer les marges d'erreur induites par les protocoles d'analyse et d'améliorer la cohérence des démarches méthodologiques (Pradat, 2015). L'intérêt dont jouit l'archéologie vivante s'est accompagné d'un renouveau des démarches expérimentales, qui permettent de tester certaines hypothèses (Toulemonde, 2014 ;Hallavant et Toulemonde, 2016).…”
