We report on two clustering chelonibiid shells from Rupelian deposits of southwestern Germany. One of these specimens displays a tripartite rostral complex and disparietal radii that indicate the Oligocene species Protochelonibia melleni, which was known so far from isolated compartments only. A literature review reveals two additional, overlooked records of the rarely reported genus Protochelonibia, coming respectively from the Burdigalian of France and the Langhian of Austria. Both these historical finds likely represent the Miocene species Protochelonibia submersa. All together, these occurrences support the notion that the protochelonibiines had acquired a broad distribution as early as in Rupelian times, when P. melleni occurred along the proto-Gulf of Mexico and in the Western Paratethys. Both P. melleni and P. submersa grew in form of peltate shells that evoke a superficial adhesion to 1 some kind of quickly moving hosts. The outer wall of the abraded German colony of P. melleni is comprised of pillar-like blocks of shelly material. In other coronuloids, similar yet more prominent septa abut outward to form T-shaped flanges and intervening longitudinal canals that facilitate the grasping of various kinds of penetrable substrates. Whether the diminutive external longitudinal parietal septa of P. melleni represent an early stage in the evolution of the coronuloid shell architecture or vestigial structures cannot be ascertained, but the former hypothesis seems to be more likely. New additions to the pre-Pliocene fossil record of Coronuloidea will hopefully clarify this and other crucial aspects of the origin and early evolution of the turtle and whale barnacles.

“…Many deep drillings in the basin and seismic lines allowed intra-basinal correlation by wire logs and biostratigraphy; the latter, however, represents a poorly constrained ecobiostratigraphy (cf. Harzhauser et al, 2020 ). Correlation with open oceanic equivalents is mostly based on planktic foraminifers and calcareous nannoplankton but also on cyclostratigraphy and astronomical tuning (Hohenegger & Wagreich, 2012 ; Hohenegger et al, 2009 ; Lirer et al, 2009 ).…”

“…This tectonic pattern also produced a complex facies distribution within the basin additionally complicated by synsedimentary tectonics (e.g., Harzhauser et al, 2017 , 2019 ; Siedl et al, 2020 ). The interplay of complex regional tectonics and global/regional sea level changes (Piller et al, 2007 ; Strauss et al, 2006 ) is also expressed in a complex lithostratigraphy which has been recently revised (Harzhauser et al, 2019 , 2020 ).

In the area of Bad Deutsch-Altenburg (Hainburg Mountains, Lower Austria) a Middle Miocene transgression over Mesozoic basement was explored in the course of the Danube power plant project “Hainburg”. The Mesozoic basement forms a narrow ridge dipping to the northeast towards the Vienna Basin, covered by various Miocene sediments. The ridge represents a specific paleotopography that required a detailed study with 78 shallow, fully cored drill holes in an area of c. 0.5 km2. Ten drillings were selected for this study based on sedimentary composition and position relative to the Mesozoic ridge. These 10 cores, ranging in drilling depth from 26.5 to 96.4 m, were studied in respect to sedimentology, corallinacean algae, calcareous nannoplankton, foraminifers and ostracodes to reconstruct sediment distribution and paleoenvironment. Sediment distribution clearly shows that the Mesozoic ridge formed a physical barrier with siliciclastics dominating in the SW of the ridge and carbonate sediments prevailing in the NE. Based on biostratigraphy (calcareous nannoplankton, foraminifera, ostracodes, dinoflagellates) the majority of the sediments can be dated to the late Badenian (early Serravallian) only in some drillholes lower Sarmatian (upper Serravallian) sediments were detected. In terms of sequence stratigraphy, the Badenian sediments represent the transgressive and highstand systems tract of 3rd order sequence TB 2.5 (bound by the lowstands Ser 2 and Ser 3), the lower Sarmatian sediments can be correlated to sequence TB 2.6. Carbonate sediments show a wide spectrum of 13 facies which are mostly dominated by coralline algae. According to the relative positions of the drill holes a water depth between 0 and about 50 m can be reconstructed what is supported by the occurrence of the benthic biota. This biota indicates that the sedimentary succession started from the very beginning under full marine conditions. Except of basal conglomerates/breccias water energy conditions were low and turbidity high. Close to the Sarmatian boundary a reduction in salinity and depth may have occurred which is also observed in the Sarmatian sediments. Carbonate sediments and, in particular, larger benthic foraminifers indicate tropical to warm-temperate conditions for the late Badenian of the studied sections. The siliciclastic sediments NW of the Mesozoic ridge reflect riverine input indicated by the occurrence of freshwater ostracodes and characean oogonias. Calcareous nannoplankton and dinoflagellates show a high share of reworking from Upper Cretaceaous and Paleogene sediments.

“…However, the detailed analyses of hundreds of Miocene samples of the Austrian Vienna Basin 70 , 71 revealed major inconsistencies between calculated BFOI values 29 and the relative trends of oxygen values 71 based on benthic foraminifers. Therefore, we saw a critical need to reevaluate the original calibrations of Kaiho 29 to further improve the usability of benthic foraminifers as a high-resolution proxy for dissolved oxygen in modern and past marine settings.…”

Marine oxygen minimum zones (OMZs) trap greenhouse gases, reduce livable habitats, a critical factor for these changes is the amount of dissolved oxygen (DO). The frequently used tool to reconstruct DO values, the Benthic Foraminifera Oxygen Index (BFOI), showed major shortcomings and lacks effectiveness. Therefore, we enhanced the BFOI and introduce enhanced BFOI (EBFOI) formulas by using all available data benthic foraminifers provide, calculating the whole livable habitat of benthic foraminifers, including bottom water oxygenation (BWO) and pore water oxygenation (PWO). Further, we introduce for the first time a transfer function to convert EBFOI vales directly into DO values, increasing efficiency by up to 38%. All formulas are calibrated on modern samples and applied to fossil datasets. Our new approach provides a major improvement in defining and reconstructing marine oxygen levels and eutrophication, by, providing a new toolset for understanding past changes and tracking actual and predicted future expanding OMZs.
