TL;DR: The Sarmatian sedimentary record of the Borod Depression (eastern Pannonian Basin) consists of a marine sequence with continental influence as discussed by the authors, which is characteristic for a shallow marine setting with local transitions to continental facies.

Abstract: The Sarmatian sedimentary record of the Borod Depression
(eastern Pannonian Basin) consists of a marine sequence with
continental influence. The investigated section, located near
Varciorog, was biostratigraphically and paleoenvironmentally
analysed. The micro-and macrofossil assemblages include
dasycladaceans, characeans, foraminifera, molluscs,
polychaetes, ostracods, crabs, bryozoans, fish and vertebrate
remains, which are characteristic for a shallow marine setting
with local transitions to continental facies. The microfossil
assemblages are characteristic for the Elphidium reginum Zone
and Mohrensternia Zone of the early Sarmatian (Serravallian).
The succession of populations correlates with the
sedimentological trend, allowing the separation of several
genetic units. The relative sea-level changes and the
progradational trend from the top of the section suggest active
tectonics in the hinterland (Apuseni Mountains). The shallow
seas surrounding the emerging islands (Apuseni Mountains)
provided the connections between the Pannonian and
Transylvanian basins during the early Sarmatian

TL;DR: In this article, a model of the semi-closed Central Paratethys Sea history was proposed for the entire time span of 25 Ma and a set of modified palinspastic palaeogeographic maps were reconstructed taking into account the enormous changes in depositional systems and sedimentary facies, reflecting the tectonic events from the Oligocene to Miocene.

Sarmatian (Late Middle Miocene) gastropod assemblages of the Central Paratethys
TL;DR: In this article, a rather diverse gastropod fauna from Sarmatian deposits of the Austrian/Hungarian Eisenstadt-Sopron Basin was studied and the fauna derives from two layers of clay and silt within a siliciclastic section at St. Margarethen in Burgenland (Austria).

Palaeoenvironmental reconstruction of the Sarmatian (Middle Miocene) Central Paratethys based on palaeontological and geochemical analyses of foraminifera, ostracods, gastropods and rodents
TL;DR: In this paper, the authors reconstructed the paleoenvironmental changes in the upper Middle Miocene Central Parathetys by using qualitative and quantitative analyses of foraminifera and ostracods, coupled with trace elemental (Mg/Ca) and stable isotope (delta(18)O and delta(13)C) analyses.
