Sažetak
The purpose of this study was to identify the ostracod assemblage from a 43 m thick section belonging to the Bizeljsko Formation of the Krško Basin situated in South-eastern Slovenia. In total, 38 samples were collected and processed in the laboratory of the Geological Survey of Slovenia. Samples were dissolved in a 5% hydrogen peroxide solution ; any samples that contained a large number of valves filled with sediment were put in an ultrasonic bath for 30 seconds. The dissolved material was then wet sieved through sieves with orifice diameters of 0.500 mm, 0.250 mm, 0.125 mm, and 0.063 mm. The determined ostracods belong to the Cyprididae, Cytheridae, Darwinulidae, and Loxoconchidae families. In total, 30 species were identified. An additional eight morphotypes were determined to the genus level. The most common genera are Candona, Hemicytheria, and Cyprideis. The assemblage belongs to the Candona (Caspiocypris) labiata biozone from the upper Pannonian. The palaeoenvironment is defined as a brackish lake with occasional freshwater influences. The ostracod assemblage from the Krško Basin shows the greatest similarity in species composition with Pannonian ostracods from Croatia and Serbia.
