The area studied, known as the Małe (Little) Pieniny Mts., belongs to the Pieniny Klippen Belt (PKB), a suture zone that separates the Central Carpathians from the Outer Carpathian accretionary wedge. Along its northern boundary the PKB is separated from the Paleogene to Early Miocene flysch deposits of the Magura Nappe by a narrow, strongly deformed belt belonging to the Grajcarek tectonic Unit. This unit is composed of Jurassic, Cretaceous and Paleocene pelagic and flysch deposits. The Klippen units of the PKB are represented by Jurassic–Lower Cretaceous carbonate deposits overlain by Upper Cretaceous variegated marls and flysch deposits. We describe geological and biostratigraphic evidence concerning the palaeogeographic, stratigraphic and structural relationships between the Pieniny Klippen Belt and the Magura Nappe, that significantly modify previously held views on the evolution of the Małe Pieniny Mts. and the Polish sector of the PKB.

Dinocyst assemblages (150 taxa) were recognised in the Lower Cretaceous deposits of the Grajcarek Unit, Pieniny Klippen Belt (West Carpathians). The following dinocyst based ages were established: a Hauterivian-Barremian boundary level age in the Sztolnia section (Pieniny Limestone Formation); a Late Barremian age of the top part of the Pieniny Limestone Formation (Rzeźnia section); a Late Barremian -Early Aptian age of the Kapuśnica Formation, Brodno Member (Rzeźnia section); latest Barremian-Early Aptian and Late Albian-Cenomanian ages of the Wronine Forma- tion (Rzeźnia section); Late Albian-Cenomanian (Hulina section) and the latest Albian-Cenomanian (Sztolnia section) ages of the Hulina Formation. Palynofacies assemblages were described and differentiated into five types, PT1 to PT5, reflecting various palaeoenvironments. Presence of anoxic events, as based on amorphous-organic-matter-dominated palynofacies, was recognized.

A geological section on Mt Hulina at Szczawnica Niżna, the Małe Pieniny Range, exposes Jurassic through Cretaceous rocks of the Grajcarek Unit, the northernmost tectonic unit of the Pieniny Klippen Belt (West Carpathians, Poland). Dark marine shales of very similar lithology, but with different microfossil assemblages, occur twice in the section, representing the Middle Jurassic (Opaleniec Formation) and the Lower Cretaceous (Wronine Formation) units of the Magura (Grajcarek) Succession, respectively. This paper presents the results of dinocyst investigations from the Opaleniec Formatiom which indicate its Bathonian age, and the Sokolica Radiolarite Formation which point out to their Middle Oxfordian - ?Lower Kimmeridgian age.

Dinocyst assemblages recovered from Jurassic strata of the Grajcarek Unit, Pieniny Klippen Belt, Poland, add new important data on their stratigraphic ages. The Jurassic ages of the Szlachtowa Formation flysch strata (Toarcian-Aalenian) and the Opaleniec Formation (Bajocian), already based on age-diagnostic macro-, micro- and nannofossils, have been confirmed. A critical evaluation of the age and field data presented in a recent paper by Oszczypko et al. (2004), who tried to prove a Cretaceous age of the Szlachtowa Formation ("black flysch") and the Opaleniec Formation, is given.
