Oligocene dinoflagellate cysts from the North Alpine Foreland Basin: new data from the Eggerding Formation (Austria)In spite of detailed geological and geophysical investigations, information available on palynostratigraphy for the successions deposited in the Austrian part of the North Alpine Foreland Basin (NAFB) is scanty. For the first time, relatively diverse and well preserved Oligocene dinocyst assemblages, comprising 53 genera and 138 species, are presented from the organic-rich sediments of the Eggerding Formation. These assemblages contribute to the biostratigraphy of the Oligocene deposits within the NAFB. Dinocysts such asChiropteridium lobospinosum, Membranophoridium aspinatum, Cordosphaeridiumspp.,Enneadocystaspp.,Deflandreaspp.,Spiniferites/Achomosphaeragroup,Hystrichokolpomaspp.,Apteodiniumspp.,Glaphyrocysta/Areoligeracomplex andWetzeliellaspp. represent the main palynological elements. The occurrence ofChiropteridiumspp.,Tuberculodinium vancampoae, Distatodinium biffiiandWetzeliella gochtiiis of particular importance for regional correlations within the Lower Oligocene sediments. A comparison with age-controlled assemblages from the North Sea Basin, Carpathian and circum-Mediterranean regions substantiate the attribution to the Rupelian. Lack or sporadic occurrence of the oceanic taxa (e.g.NematosphaeropsisandImpagidinium) and dominance ofGlaphyrocysta/Areoligeraindicate an inner-neritic marine setting during the deposition of the studied intervals. Although, it is difficult to reconstruct precisely the climatic conditions based on the recorded dinocysts, warm? sea surface water is suggested. A variation in salinities is interpreted based on the abundances ofHomotrybliumspp. The abundance of Peridiniaceae taxa (e.g.Lejeunecysta, Wetzeliella, and Deflandrea) indicates nutrient-rich surface water.

Sancay et al (2006) and Batı and Sancay (2007) recorded in detail the palynofloral content of the early Oligocene from Erzurum/Çirişlitepe, Muş/Keledeşdere and Ebulbahar. Information from palynomorphs, nannoplankton, and foraminifera suggested that early Oligocene (Rupelian) sediments were deposited under brackish water, shallow and relatively deeper marine conditions related to fluctuating sea level in the early Oligocene.…”

The continental climatic evolution of Anatolia has been reconstructed quantitatively for the last 45 million years using the coexistence approach. Although there were some regional effects, the Anatolian Cenozoic continental climate record correlated with the European climatic condition and the global oxygen isotope record from marine environments. From middle Eocene to late Miocene, continental warming in Anatolia was pronounced for inferred winter temperature and mean annual temperature as in Europe. Generally, the palaeoclimatic property of Anatolia resembles the European climatic changing and marine temperature changing based on the oxygen isotope record; however, climatic values of the terrestrial area in Anatolia are higher from Lutetian to Aquitanian and these values are lower than European values from Aquitanian to Tortonian. Correspondingly, Cenozoic climatic cooling in Anatolia is directly associated with an increase of seasonality, palaeogeographic position and terrestrial condition. Furthermore, mean annual precipitation values of Anatolia remained relatively stable during the Eocene-Oligocene; however, these values indicated changing throughout middle-late Miocene. Moreover, in this study, decline of abundance and variables for the mangrove and back mangrove palaeocommunities during the last 45 million years is recorded because of the decreasing of humidity, temperature and increasing of terrestrial condition.

“…The Ç at section occupies the northwestern part of the Turkish-Iranian Plateau, and consists of the western part of the Tekman-Karayazı-Agrı basins bounded geologically by the northern part of Bitlis-Zagros Suture Zone and the eastern part of the North Anatolian Fault zone (Ş engör and Kidd, 1979;Sancay, 2005). As the result of several new discoveries and careful reinvestigation of Oligocene fossils from Eastern Anatolia, progress regarding the systematic description and stratigraphic position of palynomorph, calcareous nannoplankton, hyalin larger foraminifera, bivalves, some vertebrate, and boine snake has accelerated significantly in the past few years (e.g., Sirel, 2003;Sancay et al, 2006;Batı and Sancay, 2007;Hoşgör and Okan, 2009;Özcan et al, 2010;Ş en et al, 2011;Szyndlar and Hoşgör, in press). The present work is the first report of the fossil fish of the Kömürlü Formation in TekmanKarayazı-Agrı basins.…”
