Histoire naturelle des phytolithes des basses-terres mayas : implication pour la reconstitution des Paléoenvironnements et des interactions sociétés-environnements

Abstract : In tropical latitudes, phytoliths represent an important indicator of the paleoenvironmental reconstitutions. Yet, they are still modestly used in past environments studies of Mayan Lowlands, despite the low potential of other vegetation bioindicators. It is in this context, and through the rich sedimentary archives of the Naachtun archaeological site and its surroundings, that we propose a new approach to exploit the inherent advantages of these siliceous microfossils for the study of past environments. Located in the extreme north of Guatemala in the subtropical Petén forest, the territory of Naachtun has been the subject of archaeological and geoarchaeological research since 2010. With its geographical location in the middle of the major Mayan political centers, this site represents a crucial space in the evaluation of the interactions between Mayan societies and the environment over the last 4 millennia, the main issue of this doctoral dissertation. To answer this question, two methodological axes have been privileged. The first axis concerns an actualist approach and aims to calibrate modern phytolith assemblages about the current natural and anthropogenic ecosystems of Naachtun and its region. The second axis, palaeoenvironmental, aims to use fossil phytolith assemblages recorded in off-site contexts, in the bajo palustrine sediments, and intra-site, to propose a reconstruction of the socio-environmental history of Naachtun. This thesis research demonstrates the potential of this new tool for the approach of palaeoenvironments in the Mayan lowlands, but it also provides new knowledge on the use of wetlands by Mayan populations. More broadly, this work is part of the current construction of an imaginary of Mayan societies conscious of their environment and adapted to its changes, a counter-example to our modern problems and crises.
