The Early to Middle Bathonian oi the Brent Group (North Sea) were cored through several Elf Aquitaine exploration wells. The analyzed core samples provided two sets oi quantitative palynological data from coal and non-coal samples. Palynomorph counts (spores, pollen grains, dinoflagellates, acritarchs, algae and foraminiferal test linings) were used in multidimensional data analyses. In the first data set (coals), three main palynological assemblages highlighting the abundance of Deltoidospora, Perinopollenites, Cerebropollenites and Lycopodiumsporites were distinguished. The study of the data set from non-coal samples revealed the presence of a transport gradient contrasting "more marine" and "more continental" samples. The "more marine" samples are characterized by diverse dinoflagellate assemblages and buoyant pollen grains such as bisaccates. The "more continental" samples exhibit two main environments: Deltoidospora swamps and Perinopollenites lagoons. The palececological trends of the palynomorphs were deduced from the study cf these main gradients. Some inferences are made about the paleoecological significance of the dinoflagellate assemblages and the different Cheirolepidiaceae pollen grains.
