Acritarch assemblages have been recovered from the Booley Bay Formation in Duncannon area, Co. Wexford, southeastern Eire. Twelve morpho‐species are described, including the new species Polygonium martinae n. sp., and two informal species Comasphaeridiu n. sp. A and Heliosphaeridium n. sp. B. A new combination, Retisphaeridium brayense (Gardiner and Vanguestaine 1971) comb. nov., is proposed. The relative ages provided by discrete microfossil assemblages and their sequence within the lithological succession suggest that the entire investigated portion of the Booley Bay Formation may be referred to the Upper Cambrian. This biostratigraphic evaluation constrains the age of the recently discovered Ediacaran‐type biota described in Crimes et al. (1995).
