A brief discussion is given of a sequence of five major problems involved in the making of a palynological contribution to the calibration of a boundary-stratotype section for a period boundary in the Global Stratigraphic Scale. It has been assumed that the Jurassic-Cretaceous boundary description will be in Europe in as Iowa palaeolatitude as possible and that it will not be taken to coincide with any described event of biologic evolution. The most appropriate and useful palynomorphs for close stratigraphic study at this level appear to be those of the Cicatricosisporites and Classopollis groups; Trilobosporites, Aequitriradites, Januasporites, and others are for various reasons considered less useful. A revised succession of Cicatricosisporites taxa is provided through the probable time interval required, and reconciliation of published taxon concepts and names is attempted.
