Ammopemphix hemisphaericus sp. nov., a new attached agglutinated foraminifer from the Pleistocene of the Arctic Ocean, and the taxonomic status of the genus Ammopemphix Loeblich, 1952
Abstract The new species Ammopemphix hemisphaericus sp. nov. is described from Pleistocene sediments of the Central Arctic Ocean. The species is a finely agglutinated monothalamous form with hemispherical shape and a terminal aperture located at the top of the test, often occurring in pseudocolonies...
