TWO NEW GENERA AND SPECIES OF ACRITARCHS FROM THE ALBIAN–CENOMANIAN OF SOUTHWEST WESTERN SIBERIA
The taxonomic composition of acritarchs from Albian–Cenomanian deposits recovered by boreholes in the southwest of Western Siberia has been studied. Two new genera and species of acritarchs have been described monographically: Pyramidinium annulatum gen. et sp. nov. and Trilobatina angusta gen. et sp. nov. The species P. annulatum is found both in the Albian, Khanty-Mansiysk Formation, and in the Cenomanian, lower part of the Uvat Formation. The species T. angusta is found only in the Cenomanian, Uvat Formation.
