Early Cambrian acritarchs from Scandinavia and Poland

Abstract
Two species of Early Cambrian acritarchs previously referred to BaltisphaeridiumB. brachyspinosum Kirjanov 1974, and B. papillosum (Timofeev) Volkova 1968 — are transferred to Comasphaeridium Staplin et al. 1965. The new species C. molliculum sp. nov. is proposed for specimens erroneously attributed by Volkova (1968) to the Ordovician species Archaeohys‐trichosphaeridium papillosum Timofeev 1959. In addition, possible colonial filamentous microfossils previously attributed to Comasphaeridium are here regarded as spheroidal aggregates of bacteria and are transferred to Globus gossipinus gen. et sp. nov. Two additional Early Cambrian acritarch taxa previously attributed to Cymatiosphaera are transferred to Fimbriaglomerella Loeblich & Drugg 1968. A species previously attributed informally to Micrhystridium Deflandre 1937, is redescribed as Multiplicisphaeridium dactilum sp. nov. The stratigraphic significance of these taxa is briefly discussed.
