More Information
Summary:In southeastern Khabarovsk krai, in the basin of the Tumnin River, the foraminifera complex containing the characteristic species Ammosiphonia beresoviensis (Bulatova), represented by exclusively agglutinated shells, is revealed for the first time in sections of Albian deposits. In terms of composition and structure, the complex is closest to the associations widespread in the Albian in the Arctic paleogeographic zone. It differs from the coeval assemblages of Sakhalin and Japan in the absence of warm-water species.
