Latest Maastrichtian Foraminiferal Abathomphalus mayaroensis Zone in the Subsilesian Unit (Polish Outer Carpathians)

Gasiński M., Leśniak T., Piotrowski M.

Bulletin of the Polish Academy of Sciences. Earth Sciences

Vol. 49, nr 2

89-97

Maastrichtian standard zones: Globotruncanella havanensis, Globotruncana aegyptiaca, Gansserina gansseri and Abathomphalus mayaroensis have been recognized within the Rybie beds of the Subsilesian unit, Polish Carpathians, based on planktonic foraminiferids. The latest zone; and the presence of its index form, are very rarely recognized in the Polish Outer (Flysch) Carpathians. Foraminiferal assemblages of the Abathomphalus mayaroensis Zone of the Rybie beds contain very differentiated planktonic, calcareous and agglutinated benthic taxa. Qualitative, quantitative and "morphogroup" analyses of the microfauna helped reconstruction of depositional environment and bathymetric conditions of the Rybie beds.
