The general 'unfossiliferous' nature of the thick, unmetamorphosed sediments of the Thule Group has been recognised since the last century. During field work in 1971 and 1974 a search was made by P. R. D. for organic remains but the only fossils encountered were stromatolites in some calcareous rocks and the trace fossils described here from thin bedded sandstones. Isotopic age dating of dolerites intruding the Thule Group shows that the Wolstenholme and Dundas Formations are of late Precambrian age and suggests that the younger Narssarssuk Formation is oi similar age (Dawes et al., 1973).
