| الوصف: |
The Late Cretaceous-Palaeogene flyschoidal deposits of the Sromowce and Jarmuta formations of the Pieniny Klippen Belt contain gravelstones composed of exotic pebbles of various lithology and age. Many pebbles are derived from the destroyed Early Cretaceous carbonate platform. They contain microfossils comparable with those of the Urgonian-type known from the peri-Medi- terranean Tethys. A rich assemblage of microfossils with characteristic: Archalveolina reicheli (de Castro), Palorbitolina lenticularis (Blumenbach), Mesorbitolina subconcava (Leymerie), Prae- orbitolina cormyi Schroeder, Pseudonummuloculina aurigerica Calvez and Simpliorbitolina manasi Ciry and Rat confirm the stratigraphical and paleoenvironmental connection of the microfossil assemblages with the classical Urgonian-type, shallow-water carbonate sedimentation. Single occurrences of planktonic foraminifera and tintinnids suggest sporadic contacts with the open sea environment and support the age designation based on benthic foraminifera. |
