Abstract
    The outcrops of the « Quartzophyllades de Chevlipont » and the« Quartzophyllades de Villers-la-Ville » in both the Dyle and Thylevalleys, in the Province of Brabant, contain acritarch assemblages ofsixty-eight species and two subspecies. Four of the species are new :Micrhystridium pellitum, Vulcanisphaera flagellum, Impluviculus lenticularisand I. stellaris. These assemblages may be divided into threezones of late Cambrian to early Tremadocian, early Tremadocian, and Arenigian or Llanvirnian — more probably Llanvirnian — age, showingthat the « Assise » de Villers-la-Ville is younger than the « Assise » deMousty, from which it is separated by a stratigraphical break.
