Abstract
The Upper Jurassic coral-algal Swarzów Formation in the Dąbrowa Tarnowska–Szczucin area, occuring in the middle part of the Carpathian Foreland Poland contains rich macrofossils (i.e. scleractinian corals, bryozoans, brachiopods, algae) and generally sparse assemblages of microfossils. Some of the latter are interesting as a biostratigraphical tool. Thus, the presence of rare calpionellids ([i]Calpionella alpina[/i], [i]C. [/i]aff.[i] alpina[/i], [i]Crassicolaria[/i] cf. [i]brevis[/i], [i]Tintinopsella [/i]cf. [i]carpatica[/i]) argues for Late Tithonian age (standard [i]Crassicollaria [/i]zone) of the upper part of this formation. It is suggested that the Swarzów Limestone Formation almost entirely represents the Tithonian, which probably reaches the lowest part of the lithostratigraphic unit of the Smęgorzów Limestone-Dolomitic Coquina Formation. The upper part of this unit may belong to the Lower Cretaceous, to Berriasian.
