PLECTOERATIDUS SUBARCTICUS, N.GEN., N.SP., A NEW AGGLUTINATED FORAMINIFER FROM THE UPPER CRETACEOUS OF THE WESTERN BARENTS SEA
We describe the new foraminiferal genus and species Plectoeratidus subarcticus n.gen. n.sp., from the Upper Cretaceous deep-water deposits of the Kviting and Kveite formations in the western Barents Sea. The genus is characterised by its planispiral-biserial-uniserial chamber arrangement, terminal a...
