Book excerpt: Detailed descriptions of acritarchs and trilobites found in the Cambrian strata of the Avalon Peninsula of eastern Newfoundland. A biostratigraphic zonation based on acritarchs is proposed, and an analysis of 7 previously described microfloras is refined and completed, enabling a more accurate correlation to be made with trilobite-bearing strata in Great Britain and Scandinavia, and with acritarch faunas in northern Norway, the Baltic area and the Gondwanaland region.
