“…While the Ries impact has been Ar-Ar-dated at a precise age of ~ 14.81 Ma 5,6 , the current best-estimate age for the Steinheim impact is derived entirely from biostratigraphic constraints. Assigning a late MN 6 to transitional MN 6/7 age to the impact, the Steinheim event most likely occurred in the terminal Langhian 12 or earliest Serravallian 58 , around ~ 14.3 to 14.0 Ma. Considering the most recent high-precision geochronologigic results for the Langhian/Serravallian boundary (13.82 Ma 59 ; ~ 13.8 Ma 60 ), a late Langhian Steinheim impact scenario 5,6 is embedded in OSM deposits that contain faunal elements characteristic for the ELMZ MN 5/6 to MN 6.…”

For decades, the Nördlinger Ries and Steinheim Basin in southern Germany have been regarded as a textbook example of a terrestrial impact crater doublet, although the oldest crater lake deposits in both craters suggest a biostratigraphic age difference of ~ 0.5 to 1 Myr. We previously presented stratigraphic arguments that challenged the double impact scenario and favoured a model of two temporally independent impact events in the Mid-Miocene. We here present, for the first time, four localities within a distance of ~ 50–100 km from the Ries and ~ 50–70 km from the Steinheim crater that expose two independent seismite horizons, together unique within the Upper Freshwater Molasse of the North Alpine Foreland Basin, each one featuring impressive water escape structures. The seismite horizons are separated by ~ 10 to 15 m of undisturbed Molasse deposits and, biostratigraphically, by an entire European Land Mammal Zone, thus providing evidence for two independent major seismic events within a time span of ~ 0.5–1 Myr. Both the lower and the upper seismite horizons can be correlated litho- and biostratigraphically with the basal crater lake sediments at the Ries and Steinheim craters, respectively, deposited immediately after the impacts. From a biostratigraphic point of view, the impact event that formed the Steinheim Basin probably occured around 14 Ma, some 0.8 Myr after the ~ 14.81 Ma Ries impact event.

A detailed description of a partial skeleton of "Mammut" borsoni from the late Pliocene (Early Villafranchian, MN 16/17) of Kaltensundheim in Thuringia (Germany) is provided, and concentrates on osteological comparisons with specimens of the European Mammutidae (Zygolophodon turicensis and "M". borsoni) and the North American Mammut americanum. Osteological similarities between "M". borsoni and M. americanum have to be regarded as parallelisms. The Kaltensundheim specimen is one of the youngest appearances of mammutids in Europe. The skeleton may represent a female, because it is distinctly smaller than male individuals from Milia in Greece of a similar ontogenetic age.We use the genus name "Mammut" in quotation marks, because the genus Mammut evolved in North America and no reinvasion into Eurasia can be proven. Therefore, the genus name Mammut should not be used prematurely for Eurasian finds.

This study provides a comprehensive examination of algal bioherm structures, including reefs and carpets that contain nannoplankton and foraminifera, originating from the upper Badenian (Middle Miocene) strata of the Vienna Basin in the Central Paratethys. These lithofacies primarily consist of calcareous red seaweeds from the Lithothamnion genus. Through an integrated approach that combines calcareous nannoplankton, foraminifera, sedimentology, and palynology, the study explores the Serravallian (upper Badenian) sediments from the Paratethys Sea shelf. The biostratigraphic age, consistent with the NN6 and CPN9 zones, is further corroborated by 87Sr/86Sr dating. Our research highlights the importance of taphonomic processes and paleoecological proxies in small-scale characterization and detecting short-term shifts within paleoenvironmental conditions. These unique bioherm structures contribute to recognizing a novel limestone formation within the Vienna Basin (The Sandberg Formation), which seems pervasive across the Central Paratethys region. The findings uphold the hypothesis of a profound connection between the Mediterranean and Central Paratethys via the Trans Tethyan Trench Corridor, bolstered by upwelling conditions observed in the eastern perimeter of the Vienna Basin. We confirm two main inhibitory mechanisms for carbonate growth in the upper Badenian epoch within the Central Paratethys area: the first is a substantial siliciclastic influx from the Alps and Carpathians, supported by the ongoing rifting of the Vienna and Danube basins; the second is the propagation of evaporites in the Transcarpathian and Transylvanian basins leading to precipitation, which disrupts carbonate growth. This investigation underlines the intertwined relationship between regional geodynamics and carbonate sedimentation processes during the Miocene era.
