Abstract
During the Tertiary, a thick sedimentary sequence was accumulated in the Bresse Basin, including some lignite that was locally excavated. Although the palynology of this lignite is relatively well known, the fossil plant macroremains were only poorly studied. Well-preserved material from a new Upper Pliocene (Reuverian) outcrop is reported herein. It allows for palaeoecological and biogeographical reinterpretation. The flora, which includes palm-trees and umbrella pine, is interpreted as a ‘Sequoia-Moor’, i.e. an acidophilic swamp-forest type that had never been evidenced from both micro- and macroremains in France. Le bassin de la Bresse a piégé au cours du Tertiaire une grande quantité de sédiments, dont des lignites, qui ont été exploités. Si la palynologie de ceux-ci est relativement bien connue, les données sur les mégarestes sont rares. La découverte d’un gisement du Pliocène supérieur (Reuvérien) particulièrement favorable permet d’apporter de nouveaux éléments, significatifs d’un point de vue paléoécologique et biogéographique. La flore, incluant des palmiers et des Sciadopitys, caractérise un « Sequoia-Moor », un type de forêt marécageuse qui n’avait jamais été mis en évidence en France conjointement par les micro- et les mégarestes.
