Lower and Middle Cambrian acritarchs from Northeastern Poland

Acid-resistant, organic-walled microfossils (acritarchs) are reported from Lower and Middle Cambrian rocks penetrated by borehole Okuniew IG-1 in the western Podlasie depression. The study showed the presence of 11 acritarch species previously known from coeval rocks in northeast Poland. The assemblage from the Okuniew borehole is compared with characteristic assemblages from other parts of the East European platform.
