Ordovician and Silurian acritarchs of the Niestachów Sandstone Formation (Góry Świętokrzyskie Mountains)

Abstract

Ordowickie i sylurskie akritarchy z formacji piaskowców z Niestachowa (Góry Świętokrzyskie) Acritarchs of the Niestachów Sandstone Formation from Niestachów in the southern part of the Góry Świętokrzyskie Mountains (the Kielce region) indicate a Silurian age of the formation, which confirms opinions expressed previously. The assemblages of acritarchs typical of Silurian include also an admixture of Ordovician species, which indicates redeposition. Twenty-two previously published species are recognised. Of these twenty-one are described together with three taxa which are not specifically assigned.
