The Miocene deposits of the Hrvatska Kostajnica (KOS-I) area belong to the south-western marginal part of the Pannonian Basin System (PBS). Investigation of the lithostratigraphical column included: mineralogical, geochemical, sedimentological and integrated palaeontological (calcareous nannofossil, foraminifers, ostracodes, palynomorphs) analyses. Badenian and Sarmatian sediments of this column were deposited in a marine offshore environment with local input of terrigenous material represented by marls and silty marls. Based on palaeontological data, the recorded palaeoclimate was subtropical in the late Badenian changing to a warm temperate climate of the early Sarmatian. Marly sediments predominantly consist of carbonate (calcite and aragonite) and clay minerals, while quartz and plagioclase are less abundant. Most samples contain a small amount of zeolite minerals from the clinoptilolite/heulandite series. Among the clay minerals, smectite and illite/muscovite are the most abundant. Based on provenance analyses we concluded that the Badenian-Sarmatian marls were predominantly formed by the weathering of acidic (Si-rich) source rock derived material from the neighbouring Inner Dinarides.

This paper describes Middle Miocene (Badenian) shark teeth from Serbia and discusses their geographical distribution at other localities of the Central Paratethys. The shark teeth originate from Visnjica (near Belgrade), from Visnjica Clay, or the ?Pleurotoma Clay?. The variety of sharks is very low, but according to these fossils Visnjica is the richest among serbian localities. The sharks teeth reported in the paper belong to the following taxa: Otodus (Megaselachus) megalodon (AgAssiz, 1835), Hemipristis serra AgAssiz, 1835 and Odontaspididae indet. The high diversity of invertebrates (molluscs, echinoids, corals etc.) and other coeval fossil assemblages indicate a warm period (the Middle Miocene Climatic Optimum), which preceded the Middle Miocene Climatic Transition.

Abstract During the Middle Miocene, the northern Croatian Medvednica Mt. was an island within the Pannonian Basin System, situated on the SW margin of the Central Paratethys Sea. Miocene sedimentary rocks (the Late Badenian Bulimina–Bolivina Zone and Ammonia beccarii ecozone), from the SW slopes of Medvednica Mt. clearly reflect a transgressive-regressive cycle with emersion during the Badenian/Sarmatian boundary. After the initial phase of transgression, the pioneer Elphidium–Asterigerinata–Ammonia benthic foraminiferal assemblage is present in bioclastic limestones, such as those at the Borovnjak locality. This marginal marine assemblage from a highly energetic, normally saline environment is characterized by poor preservation of foraminiferal tests, low diversity and strong domination. Advanced transgression is followed by establishment of the Elphidium–Asterigerinata assemblage, which is found in biocalcsiltites from the laterally deeper and more sheltered environment at Gornje Vrapče. This diverse assemblage is typical for inner/middle shelf environment with sufficient oxygen content. A general shallowing upward trend can be recognized at both localities, followed by visible interchange of different sedimentological and biotic features. Successive and oscillatory regression in the marginal marine environment was followed by salinity fluctuations and final brackish conditions with Ammonia–Elphidium assemblage. The laterally deeper environment reacted to regressive trends on finer scale with almost regular changes of benthic foraminiferal assemblages in the laminae (Heterolepa–Bolivina assemblage/Bolivina–Cassidulina assemblage/Elphidium–Asterigerinata assemblage). It might reflect sea-level oscillations with periodically increased siliciclastic and nutrient input from land or influence of seasonality on benthic assemblages, which occurred in the advanced phase of the regression near the Badenian/Sarmatian boundary.
