“…In the upper part of the section (62-102 m) ostracod assemblage bears Limnocythere, Ilyocypris and Dinaro cythere. The genus Ilyocypris is known from presentday freshwater streams, ponds and shallow lakes, with a preference for spring-supplied water (Meisch 2000, Rodríguez-Lázaro and Martín-Rubio 2005, Wil kinson et al 2005. Some species such as I. bradyi SARS are generally associated with waters of a very low salinity (average 3.24‰), but might tolerate salinity up to 14‰ (Li et al 2010).…”

With 12 figures and 2 tables Abstract. During the Early to Middle Miocene, a complex interplay of climate variability, sea level change, and Alpine tectonics resulted in the development of a series of long-lived lakes in the Dinarides and Serbian regions. While recent dating studies improved understanding of the Dinaride Lake System (DLS) evolution, independent age constraints are still lacking for the Serbian Lake System (SLS). Here, we present the results of an integrated study combining biostratigraphy, magnetostratigraphy, and 40 Ar/ 39 Ar radioisotopic dating of the sedimentary succession of ancient Lake Popovac to improve the chronostratigraphic framework and paleoenvironmental understanding of the SLS. Our biostratigraphic analyses of the mollusks and ostracods show endemic marker taxa for the Middle Miocene bioprovince of the SLS, such as Prososthenia fuchsi PAVLOVIĆ, ?Mediocypris sp., and ?Dinarocythere sp. Magnetostratigraphy revealed only one normal polarity interval, with a single reversed sample on top and, combined with an 40 Ar/ 39 Ar weighted mean crystallization age of 14.40 Ȁ 0.01 Ma, we correlate the studied Lake Popovac succession to Chron C5ADn, with a maximum extent from 14.61-14.16 Ma. Cyclostratigraphic analysis based on magnetic susceptibility and natural gamma radiation field logs suggest insolation forcing of the succession with an upward decrease in sedimentation rate from 25 to 12 cm/kyr. While the majority of the DLS originated during the Miocene Climatic Optimum (MCO) at ~17 Ma and disappeared before ~15 Ma, the development of the SLS started around 14.5 Ma in the Langhian. Regionally overlying Serravallian marine sediments of the Central Paratethys imply that the Serbian Lake cycle must have ended before 13.8 Ma. Initiation of SLS deposition in the study area coincided with a peak of syn-rift extension in the Pannonian back-arc basin, which apparently also affected the Peri-Pannonian realm as far south as the study area in the Morava depression.
