Abstract

An assemblage of pollen and spores from the Upper part of the Heiberg Formation of Arctic Canada is illustrated and discussed. From its stratigraphic position and from the palaeontology of underlying and overlying strata, it is deduced that the assemblage must be older than the Sinemurian Stage of the Lower Jurassic, and younger than the FG subzone of the TK zone of Morbey (1975). The assemblage itself compares closely with that described from the Psilonoten Schichta of Eastern Germany by Schulz (1967). It is therefore postulated that the beds carrying the assemblage are Hettangian in age, correlating with the lower beds of the Blue Lias of Western Europe.
