“…This absence could be explained by the presence of a sedimentary gap, the so-called pre-Riesian hiatus. Indications of a hiatus have been found in the sedimentary record at the northern margin of the Bavarian part of the Molasse Basin with up to 150 m deep erosional channels (Birzer 1969) and as a turnover in the mammal record throughout the basin (Bö hme et al 2002). This turnover is contemporaneous with a stratigraphic gap between biostratigraphic units OSM C + D and OSM E (Fig.…”

“…Within our studied section we have no fossil localities belonging to OSM E' or F. To date, OSM E' is documented in one locality only (Derching 1b, Augsburg area), found in a sandy unit 2 m below the Brock horizon (Bö hme et al 2002). All localities belonging to OSM F are found between the Brock horizon and the main bentonite layer, both in the Landshut (e.g., Sallmannsberg) and the Augsburg area (e.g., Laimering 3) (Heissig 1997).…”

“…Although a detailed (micro)-mammal biostratigraphy has been established for Miocene deposits of the Molasse Basin (Heissig 1997;Bö hme et al 2002) it does not provide a precise temporal resolution necessary for establishing a causal link between the stratigraphic record of the Molasse Basin and the tectonic evolution of the Alps as well as global climate change. Recent studies in the Swiss part of the Molasse Basin have successfully established a detailed magnetostratigraphic and biostratigraphic framework for Oligocene to Middle Miocene sequences (Schlunegger et al 1996;Kempf et al 1997Kempf et al , 1999.…”

Karydomys, a rare genus of cricetid rodents from the Middle Miocene of central Europe, had previously been reported only from the Swiss part of the North Alpine Foreland basin; documented evidence from the German part was lacking. This paper describes several new specimens of Karydomys from the German localities Ho ¨ll and Laimering 3. A correlation of both localities to the Bavarian local biostratigraphic scale OSM F is proposed. Taxonomically, the fossils are most probably linked to K. wigharti from Hambach 6C (north-west Germany), and thus assigned to K. cf. wigharti. In spite of the scarcity of Karydomys fossils in the Upper Freshwatermolasse, the taxon is an important biostratigraphical marker because of its short stratigraphical range.

The Early to Middle Miocene Fluviatile Untere Serie lithostratigraphic unit of the Upper Freshwater Molasse (UFM) in the North Alpine Foreland Basin (NAFB) crops out in a 40 m long section at Untereichen-Altenstadt (central part of the NAFB). This section yields a unique superposition of two vertebrate assemblages belonging to different biostratigraphic units: early part OSM C + D (Karpatian) and OSM E (Early Badenian). Detailed taxonomic analyses reveal different diversity patterns in the two assemblages. Nine small mammal and six ectothermic vertebrate taxa occur in the older level UA 540 m, while 20 small mammal and 23 ectothermic vertebrate taxa are recorded for the younger level UA 565 m. From the latter locality comes a small-sized representative of the biostratigraphically significant Megacricetodon lappi lineage. This evolutionary level has not been documented previously for the eastern part of the NAFB. Bioclimatic analysis combined with lithofacies and architectural element analysis indicates that significant changes in the fluvial sedimentation style, surface-water runoff and tectonics occurred between the Early Karpatian and Early Badenian. A meandering fluvial system (marly unit) is erosively overlain by sandy braided river deposits (sandy unit). Overbank deposits of the marly unit revealed that the older vertebrate fossil assemblage (UA 540 m) is deposited in an animal burrow that was presumably produced by owls. Both reptilian and mammalian taxa are indicative of a relatively open environment and dry, probably semi-arid climate. Conversely, vertebrates from the sandy unit (UA 565 m), which are accumulated in channel fill deposits, suggest closed as well as open habitats with a subtropical humid climate and mean annual rainfall of about 1,000 mm. According to the sequence stratigraphic analysis the marly unit is interpreted as a highstand-system-tract of the TB 2.2 global 3rd order sequence. The new results add support to the hypothesis that the erosional unconformity between both sedimentary units spanning the KarpatianBadenian transition corresponds to the pre-Riesian hiatus, which has been interpreted as part of the Styrian Tectonic Phase, and was previously identified only in the eastern and northeastern part of the NAFB. The biostratigraphic data further indicate that this hiatus lasted longer in the eastern than in the central part of the basin.
