Planktonic, acid-resistant microfossils from Upper Proterozoic strata of the Barents Sea Region of Varanger Peninsula, East Finnmark, Northern Norway.
Planktonic, acid-resistent microfossils (acritarchs) occur in the Kongsfjord, Båsnæring and Båtsfjord Formations of the Barents Sea Group and in the Styret Formation of the Løkvikfjell Group. Two new taxa are described and additional data are presented on the previously known species. The state of p...
