Abstract. Marine organic-walled dinoflagellate cysts have been studied from the Early and Middle Miocene of the Central Paratethys in Austria (Vienna and eastern Alpine Foreland basins) and Hungary (Pannonian Basin), and compared with assemblages of similar age from the Atlantic Ocean and Mediterranean Sea. The presence of a diverse flora of 71 taxa, including such biostratigraphical markers as Apteodinium spiridoides, Cerebrocysta poulsenii, Cordosphaeridium cantharellus, Cribroperidinium tenuitabulatum, Exochosphaeridium insigne, Glaphyrocysta reticulosa s.l., Habibacysta tectata, Labyrinthodinium truncatum subsp. truncatum, Palaeocystodinium miocaenicum, and Unipontidinium aquaeductus, has allowed the establishment of five biozones that characterize the Ottnangian, Badenian and Sarmatian local stages (collectively equivalent to the mid-Burdigalian, upper Langhian and Serravallian stages). This is the first study to demonstrate the applicability of dinoflagellate cysts for detailed stratigraphic correlation and palaeoenvironmental interpretation in the Early and Middle Miocene of the Central Paratethys area.

Tuffaceous layers are regularly preserved in Miocene carbonate and siliciclastic sediments of the Dinarides and Eastern Alps in southeastern and central Europe. Detailed mineralogical and geochemical analyses of 13 tuffs of known ages acquired from sedimentary successions of the intramontane Dinarides basins and the southwestern Pannonian Basin were carried out to infer on plausible source areas, relative strengths of volcanism, and ash distribution patterns. Studied tuffs were altered to various degrees with illite-smectite and smectite as dominant phases while volcanic glass, carbonates, and other silicates are minor constituents. Tuffs’ compositions range from andesite through trachyandesite to rhyolite and trachyte. Trace-element based correlation with regional data reveal that lower (LM) and lower middle Miocene (LMM) tuffs (17.0-14.0 Ma) likely originated in the Western Carpathians (the Bükkalja volcanic field) while source areas of upper middle Miocene (UMM) tuffs (13.8-12.5 Ma) were in the Apuseni Mountains and/or Eastern Carpathians. The spatial relation of LM/LMM and UMM tuffs with respect to their source areas (Bükkalja and Apuseni Mountains, respectively) is most consistent with tropospheric easterly trade winds that carried ash hundreds of kilometres to the south-west toward an azimuth of ∼200-250°.Supplementary material: Annotated X-ray diffractograms of the global and clay fraction of studied tuffs and AFM classification diagram are available at https://doi.org/10.6084/m9.figshare.c.5429592

New finds of teeth and mandibles of Anchitheriomys from the Hambach opencast lignite mine in Northwest Germany and the first detailed descriptions of other mandibles from South Germany and Switzerland allow a review of the Central European specimens of this rare beaver genus. The metric variation of cheek teeth and especially the great differences in dimensions of incisors can be much better assessed. The observed range in size can be attributed to ontogenetic changes, and all material is assigned to Anchitheriomys suevicus. Stratigraphically, this species is restricted to the early middle Miocene, European Mammalian Neogene biozones MN 5–6.

ABSTRACT The scarcity of stratigraphic data has hindered the demarcation of the outcropping area of Miocene deposits of the Amazon Basin, represented informally by the Novo Remanso Formation. Moreover, this unit is characterized by a sparse and irregular geographic distribution due to its sedimentological features and rare fossil content. Miocene deposits cropping out in central Amazonas Basin area were described in sedimentological terms and analyzed palynologically. All analyses were undertaken in samples collected at the Uatumã River banks (Itapiranga and São Sebastião do Uatumã cities). Lithostratigraphic data shows that Novo Remanso Formation consists of sandstones, with subordinate conglomerates and pelites, characteristic of a meandering fluvial paleosystem, with fluvial channel, point bar, floodplain and crevasse splay facies. The palynoflora retrieved from five samples consists exclusively of continental-origin palynomorphs dominated by angiosperms species. Trilete spores are well represented, while gymnosperms pollen grains are minor components. The presence of Psilastephanoporites tesseroporus, Syncolporites poricostatus, Jandufouria seamrogiformis and Polypodiaceoisporites potoniei ensure these deposits fits into the Grimsdalea magnaclavata palynozone (Regali et al. 1974a, b), and the Grimsdalea magnaclavata/Crassoretitriletes vanraadshooveni palynozones of Jaramillo et al. (2011) considered Middle Miocene age. This age is confirmed by the zonation of Jaramillo et al. (2011), based on the LADs of Bombacacidites baumfalki (11.57Ma) and Crototricolpites annemariae (12.91Ma); and the FAD of Psilastephanoporites tesseroporus (14.00Ma). With these new data presented herein, it is possible to assume that the Miocene strata represented by the Novo Remanso Formation covers a larger area in the basin than previously considered, and that it may be extended for about 300 km until the Manacapuru village, indicating a Miocene subsidence phase.
