A Middle Cenomanian foraminiferal assemblage from the Nowe Rybie section (Żegocina Tectonic Window, Subsilesian Unit, Polish Outer Carpathians)

The Żegocina Tectonic Window is the most eastward located tectonic window of the Lanckorona-Żegocina Zone in the Polish Outer Carpathians and represents the slope parts of the Silesian basin and intrabasinal uplifted zones of the Subsilesian Unit. Upper Cretaceous and Palaeocene variegated marls, typical deposits of the studied part of the basin, are intercalated with the so-called Rybie beds (local sediments of siliciclastic submarine fans). A Middle Cenomanian foraminiferal assemblage (Rotalipora reicheli Zone) is here described from these sediments. The assemblage contains numerous planktonic (epipelagic and bathypelagic) foraminiferids, which is rather unique within the "Flysch" type assemblages. A middle slope palaeodepth is suggested as the depositional environment, based on benthic and planktonic foraminiferal associations.
