Description du projet
Un projet paléontologique de grande ampleur au Soudan
La recherche paléontologique en Afrique a mis au jour un riche éventail de fossiles datant du Pléistocène. La majorité des sites fossilifères se situent toutefois dans la vallée du rift Est-Africain (EARV), ce qui crée un biais géographique. Notre connaissance des faunes régionales ainsi que du rôle de la dispersion et de la variation géographique dans l’apparition des écosystèmes modernes (y compris les êtres humains) est dès lors limitée. De plus, le rôle du Nil dans la dispersion faunique et culturelle n’est pas suffisamment étudié. Le projet PALEONILE, financé par l’UE, combinera des approches paléontologiques, géologiques, géochronologiques et archéologiques pour mettre au jour de nouveaux fossiles dans le bassin du Nil au Soudan. En outre, il testera des hypothèses sur la régionalisation zoogéographique du Pléistocène dans le bassin du Nil en relation avec l’EARV et les zones avoisinantes.
Objectif
Over a century of paleontological investigation in Africa has revealed a rich Pleistocene fossil record that includes the evolution of hominins and their material cultures. However, the vast majority of fossil sites are located in the East African Rift Valley (EARV), and our knowledge is heavily skewed by this geographic bias. Poor continental geographic sampling means we lack an understanding of faunal regional variations, and the role of dispersal and geographic variation in the emergence of modern ecosystems. Furthermore, many have questioned the role of the Nile, the longest river in the world, in promoting faunal and cultural dispersal between Subsaharan and North Africa, and beyond to Eurasia. For decades such questions have been answered speculatively, with little data to stand on. PALEONILE is an ambitious project that will address these major gaps in our knowledge through large-scale surveys to reveal a new fossil record from the Middle Nile River Basin in Sudan. This project will test an overarching hypothesis of Pleistocene zoogeographic regionalization in the Nile Basin with respect to the EARV and surrounding areas, and will use an interdisciplinary array of paleontological, geological, geochronological, and archaeological approaches to reach its objectives. The geographic scale of the project is large and the techniques are cutting edge, including high-risk experimental methodologies such as paleobiomolecular recovery and new developments in sedimentary dating. PALEONILE forms the first ever large-scale systematic paleontological project to be conducted in Sudan, where the Cenozoic fossil record remains largely undiscovered, and its potential overlooked. PALEONILE will generate a new paradigm of zoogeographic dynamics and evolution in the African Pleistocene that represents a new synthesis of hydrographic, phylogenomic, archaeological, and paleontological evidence.
