AB Les Vilelles unit is a detrital sequence exposed at the southwestern margin of the Catalan Coastal Chain (CCC),NE Spain, below the Carboniferous turbiditic series. Based on the palynological content, the age of this unit wasinitially assigned to the Middle-Late Devonian (Eifelian to Famennian). Additional radiolarian and conodontfindings were considered to be Early–Middle Mississippian (Tournaisian to early Visean). To clarify this agediscrepancy a new and more comprehensive palynostratigraphic analysis has been conducted in the upper partof the section representative of Les Vilelles unit. This has provided an assemblage of miospores, acritarchs,prasinophyta phycomata and chitinozoans that can be confidently assigned to a latest Frasnian interval, in contactwith the Frasnian–Famennian boundary. Therefore, the present analysis refines the Middle–Late Devonian ageformerly assigned, establishes a latest Frasnian age for the top of the unit, and provides new insights to the betterunderstanding of the unconformity and hiatus separating the pre-Carboniferous and Carboniferous CCC series inthe Priorat Massif. The study also includes a systematic section with the description of three newly establishedmiospore species: Dibolisporites coniugatum, Dibolisporites prioratum and Rugospora spinosa.
