New acritarch data combined with the trilobite record date most of the WiÊniówka Hill succession (western part of ¸ysogóry, Holy Cross Mts.) as early Furongian (early late Cambrian). The taxonomic diversity and abundance of the acritarch assemblages allow a more precise age determination than previous studies, as well as correlation with contemporary associations from Baltica, Avalonia and West Gondwana. The stratigraphic significance of trilobite trace fossils within the succession is evaluated.
