ResumoAbstractNew palynological analysis of the Arcillas de Morella Formation provides data for determinations of age of the Lower Cretaceous strata in the Ermita Sant Antoni de la Vespa section located in the district of Els Ports in the Morella sub-basin of Castellón province, north-eastern Spain. Controversy still exists over the age of this formation, which is imprecisely dated as either Barremian or Aptian in age. Detailed reconnaissance of palynological content (dinocyst, pollen and spore assemblages) together with ammonoid data permits a more accurate biostratigraphic assessment of this deposit. The presence of Subtilisphaera terrula, Florentinia mantelli and Oligosphaeridium abaculum indicates a Barremian age at the base of the formation. The presence of Stellatopollis at the top of this formation possibly indicates that the deposit may be as old as latest Barremian. Furthermore, a recent study of ammonoids situated the Barremian-Aptian boundary within the overlying Cap de Vinyet Member of the Forcall Formation in the Morella sub-basin. This study together with the palynological assemblage from the Arcillas de Morella Formation indicates a Barremian age for this deposit.Keywords:: palynologyEarly CretaceousArcillas de Morella FormationCastellónMaestrazgo BasinView correction statement:Corrigendum AcknowledgementsThe authors acknowledge the CGL2008-06533-C03/BTE Project (Ministry of Education and Science).
