A palynological study of the Late Pliensbachian-Early Toarcian deposits in the Traras Mountains (NW Algeria) identified sporomorphs (spores and pollen grains) associated with acritarchs and algae unknown in this Algerian basin at this time. Seeking to characterize the Pliensbachian-Toarcian transition, the results of qualitative and quantitative analysis of pollen assemblages generated new stratigraphic information on the lower limit of Bayada beds which have already been established by ammonites, brachiopods and foraminifera.
