Late Maastrichtian to Paleocene distal flysch sediments of the Raca Unit (Outer Flysch Carpathians) at the Uzgrun section provided a relatively rich fossil record (foraminifers, radiolarians, calcareous nannofossils). The Upper Maastrichtian can be subdivided into three calcareous nannofossil zones and the Paleocene assigned to one agglutinated foraminiferal zone. Some prospective new marker species of agglutinated foraminifers for subdivision of the Maastrichtian-Paleocene are discussed. The well preserved (pyritized) radiolarian fauna has brought interesting data on the radiolarian biostratigraphy. The integrated microbiostratigraphy approach enabled us to find the Cretaceous/Tertiary transition in a continuous flysch sequence of one partial outcrop. The transition is characterized by an increase in the frequency of coarser turbidite intervals and disappearance of calcareous sediments. The nannofossils show the influence of both Boreal and Tethyan bioprovince on the Magura depositional area.
