“…This suggests that Lake Pannon initially had a marine sulphate signature, reflecting its Central Paratethys Sea heritage. Likewise, during isolation of Lake Pannon from the Paratethys Sea 16,18,19 , Vienna Basin sediment could still have contained sufficient organic matter for methane production at depth. The still high sulphate pool and enhanced methane flow would have, thus, stimulated SD-AOM and enhanced sedimentary methane consumption.…”

“…The lake formed after a glacio-eustatic sea-level drop at ~11.6 Ma (Fig. 1), which led to final disintegration of the central and southeastern European Paratethys Sea [17][18][19] . During its maximum extent between 10.5 and 10.0 Ma, it covered around 233,500 km 2 , attaining more than half the size of the modern Black Sea with a greatest depth of around 1000 m 17 .…”

“…During its maximum extent between 10.5 and 10.0 Ma, it covered around 233,500 km 2 , attaining more than half the size of the modern Black Sea with a greatest depth of around 1000 m 17 . Biota and sedimentary features indicate that Lake Pannon was initially brackish and that it freshened gradually following isolation from the Paratethys Sea 16,18,19 . Its marine heritage might have impacted lake water sulphate concentrations and methane-related carbon cycling during early-stage lake evolution.…”

Sulphate deficiency makes lake environments a key source of atmospheric methane because sulphate-driven anaerobic oxidation of methane (SD-AOM) is hindered. Miocene to Pliocene Lake Pannon was the largest European lake, although the extent of its methane production remains unclear. When sulphate is available, SD-AOM occurs commonly in anoxic sediments and is recorded by authigenic iron sulphides. Here we identify abundant tubular pyrite and greigite aggregates from Lake Pannon sediments, which record brackish early lake conditions at ~11.3 Ma. The iron sulphides are morphologically similar to those reported elsewhere from methane seep and gas hydrate environments. Microscale sulphur isotope analysis and multiple sulphur isotope patterns of iron sulphides, and elevated sedimentary Ba/Al and Mo/Al ratios, are consistent with their derivation from SD-AOM under marine conditions. These results indicate substantial methane consumption in early Lake Pannon, and that sulphate was the dominant oxidant for AOM, which reduced the release of sedimentary methane to the atmosphere. SD-AOM signals archived by iron sulphides are valuable for evaluating methane consumption in lacustrine sediments.

“…The Western Paratethys disappeared during the late Early Miocene, due to tectonic uplift 12 . The Central Paratethys existed until the Middle/Late Miocene boundary, when the area was transformed into the brackish Lake Pannon that gradually became filled by fluvial deltas during the Pliocene 13 – 15 . The Eastern Paratethys persisted throughout the Oligocene to Pleistocene with strongly changing shorelines, and its remnants are still represented by the Black Sea, the Caspian Sea and the Aral Sea 4 , 16 – 18 .…”

The Miocene Climate Optimum (MCO, ~ 17–14 Ma) was a time of extraordinary marine biodiversity in the Circum-Mediterranean Region. This boom is best recorded in the deposits of the vanished Central Paratethys Sea, which covered large parts of central to southeastern Europe. This sea harbored an extraordinary tropical to subtropical biotic diversity. Here, we present a georeferenced dataset of 859 gastropod species and discuss geodynamics and climate as the main drivers to explain the changes in diversity. The tectonic reorganization around the Early/Middle Miocene boundary resulted in the formation of an archipelago-like landscape and favorable conditions of the MCO allowed the establishment of coral reefs. Both factors increased habitat heterogeneity, which boosted species richness. The subsequent cooling during the Middle Miocene Climate Transition (~ 14–13 Ma) caused a drastic decline in biodiversity of about 67%. Among the most severely hit groups were corallivorous gastropods, reflecting the loss of coral reefs. Deep-water faunas experienced a loss by 57% of the species due to changing patterns in circulation. The low sea level led to a biogeographic fragmentation reflected in higher turnover rates. The largest turnover occurred with the onset of the Sarmatian when bottom water dysoxia eradicated the deep-water fauna whilst surface waters-dwelling planktotrophic species underwent a crisis.

“…A position within an orogenic belt commonly leads to the isolation of water bodies formed in intermontane basins from the world's oceans, indeed, frequently even from basins in adjacent regions. The freshwater, brackish and occasionally endemic character of the biota complicates the age determination through biostratigraphy (Harzhauser and Mandic, 2008;Pipík et al, 2012;Magyar, 2021). The frequent presence of hiatuses related to base-level changes may obscure the interpretation of magnetostratigraphic records (Langereis et al, 2010).…”
