Description: It has long been proposed that during Pleistocene climatic perturbations the Balkan peninsula sustained refugial areas for fauna, flora, and potentially, hominins. In this study, we explore Middle Palaeolithic subsistence at the peninsula's southern end, Greece, and discuss how the evidence contributes to our understanding of the region's character as a refugium. We present new data from the recent reanalysis of the fauna from Asprochaliko rockshelter and the ongoing zooarchaeological investigations at Lakonis Cave 1 and compare them with published analyses from Klissoura Cave 1. We employ taxonomic abundance and diversity indices, as well as mortality profiles, to investigate hominin prey choice. Additional taphonomic observations provide further information on carcass exploitation. We examine changes in the faunal composition of the three sites in an attempt to identify the extent to which climate might have influenced resource availability and diversity in the region, stimulating resource intensification or diversification processes. Our results suggest that Middle Palaeolithic hominins consistently acquired high‐ranked prey through time. However, interregional differences in resource exploitation indicate that local topography and microclimate mediated prey choice and availability.

Description: Upper Devonian carbonates deposited through the Frasnian/Famennian (F/F) stage boundary in the Xom Nha Formation, Central Vietnam, were studied. The section is mainly composed of fossiliferous, brecciated, and laminated limestone beds, while shale beds occur in a subordinate number. Microfacies generally suggests a hemipelagic setting on an outer shelf environment with low sedimentation rates. A sediment accumulation rate of 0.217 cm/kyrs for this section is calculated. The Xom Nha section does not exhibit characteristic black shales or black limestones through the F/F boundary, but instead shows a similar lithology in comparison to other F/F sections in Southeast Asia. The carbonates yielded abundant conodonts, which represent mainly cosmopolitan species but the section differs from most sections in Europe in showing relatively high numbers of Palmatolepis linguiformis species. Deposition through the F/F boundary interval reported here for the Xom Nha section appears to have occurred during a ~1.2 Ma, and shows well-defined climate cyclicity.

Description: Closure of the Central American Seaway (CAS) and hydrology of the Caribbean Sea triggered Northern Hemisphere Glaciation and played an important role in the Pliocene to modern‐day climate re‐establishing the deep and surface ocean currents. New data on Mn/Ca obtained with femtosecond laser ablation inductively coupled plasma mass spectrometry on well‐preserved tests of the epibenthic foraminifer Cibicidoides wuellerstorfi and infaunal C. mundulus contribute to the interpretation of paleoenvironmental conditions of the Caribbean Sea between 5.2 and 2.2 Ma (million years) across the closure of the CAS. Hydrothermal activity at the Lesser Antilles may be a primary source of Mn in the well‐oxygenated Plio‐Pleistocene Caribbean Sea. Incorporation of Mn in the benthic foraminifer shell carbonate is assumed to be affected by surface ocean nutrient cycling, and may hence be an indicator of paleoproductivity.

Description: Plain Language Summary: The closure of the Panama Isthmus caused the expansion of ice sheets in the Northern Hemisphere and changed the water current dynamics and climate in the Caribbean Sea since the Pliocene (∼5.3 million years ago). New Mn/Ca data measured using femtosecond laser ablation inductively coupled plasma mass spectrometry on the deep‐sea benthic foraminifer species Cibicidoides wuellerstorfi and Cibicidoides mundulus help us understand past environmental conditions of the Caribbean Sea prevailed between 5.2 and 2.2 million years ago. While manganese might be sourced from the surrounding hydrothermal vents, its incorporation in the foraminifer shell carbonate might be related to nutrient cycling and may indicate past biological productivity in the ocean.

Description: Key Points: Femtosecond‐laser ablation inductively coupled plasma mass spectrometry provides a new approach on distinguishing Mn of the ontogenetic shell calcite from Mn of the authigenic coatings. Ontogenetic Mn within the foraminifer shell calcite may result from the regional nutrient cycle. Mn in the deep eastern Caribbean Sea may mainly derive from hydrothermal sources along the Antilles Island Arc.

Description: The Bayankhoshuu Ruins section in southern Mongolia is characterized by strongly thrusted and folded sequences. Overall, three sections ranging from Ordovician to Carboniferous rocks were studied. Facies analysis combined with stratigraphic data provide improved lithostratigraphic descriptions of Palaeozoic successions in the Mushgai region. The overall marine sedimentary sequence is punctuated by volcanic rocks–basaltic lava of Silurian and Middle Devonian age and volcaniclastic bentonite and tuff in the Middle to Late Devonian and Mississippian suggesting an island arc setting. The Minjin Member of the Botuulkhudag Formation (Middle Devonian to Late Devonian) is primarily composed of thick basaltic and subaerial volcanic rocks with minor silicified siltstone and chert inclusions. Thicker successions of limestone occur in the Ordovician/Silurian, Early Devonian, and the Mississippian. The macrofauna is scarce, except distinct limestone horizons where different fossil groups were recognized. Microfossils, such as radiolarians and conodonts, are scarce and generally poorly preserved. However, based on the re-study of collections from earlier publications and new conodont data, a more detailed biostratigraphic record of the Khoyormod, Botuulkhudag, and Arynshand formations of the Bayankhoshuu Ruins section can be developed. For instance, the Arynshand Formation likely ranges from the late Bispathodus ultimus conodont biozone to the Scaliognathus anchoralis–Doliognathus latus conodont biozone. A tectonic breccia occurs in the early Mississippian and is overlain by a red shale of remarkable thickness at the top of this formation which points to subaerial exposure in the early Mississippian (near the Tournaisian/Visean transition). Due to strong tectonic overprint and/or facies, some unconformities/hiatuses occur. Most strata are intensively folded and faulted, ranging from centimeter to meter scale. Overall, deposition likely occurred on either the Mandalovoo or Gurvansayhan Terrane.

Description: The Kimmeridgian Alcobaça Formation of the Lusitanian Basin forms a mixed carbonate–siliciclastic unit between basinal deposits of the Abadia Formation, and fluvial–terrestrial strata of the Lourinhã Formation. This study presents 〉2.5 km of detailed logs of nine outcrop sections of the Alcobaça Formation in its type region. Eight of these sections encircle the Caldas da Rainha Diapir, which was a prominent, emergent, passive salt diapir during the time of deposition. Palaeoenvironments of the unit form a complex mosaic of low- to high-energy, carbonate- or siliciclastic-dominated shallow shelf settings; coastal embayments and lagoons; and coastal plains with rivers, lakes and playas. In the strata, abundant microfauna is often joined by a rich macrofauna, usually dominated by bivalves. Locally, corals, calcareous sponges or oysters form meadows or patch reefs. These autochthonous to parautochthonous remnants of former communities are assigned to 35 benthic macrofaunal associations. The integration of palaeoecological analysis of these associations with microfaunal and sedimentological data provides constraint on their salinity ranges, which range from slightly hypersaline to freshwater. Frequent temporal and spatial salinity fluctuations are attributed to variations in relative sea-level, salt tectonics or climate. The NNE-trending Caldas da Rainha Diapir induced pronounced facies differentiation. Predominantly, non-marine siliciclastic facies in the northwest and carbonate to siliciclastic, marine to brackish facies in the southwest are contrasted by shallow-marine carbonate facies east of the diapir. Comprehensive exposure and well-preserved fossils make the Alcobaça Formation an excellent showcase to demonstrate how biofacies analysis can help to disentangle the interplay of climate changes, sea-level fluctuations and salt tectonics. Based on the improved characterisation of the unit, the Alcobaça Formation is formally defined, and seven members are established.

Description: The biggest known mass extinction in the history of animal life occurred at the Permian–Triassic boundary and has often been linked to global warming. Previous studies have suggested that a geologically rapid (〈40 kyr) temperature increase of more than 10°C occurred simultaneously with the main extinction pulse. This hypothesis is challenged by geochemical and palaeontological data indicating profound environmental perturbations and a temperature rise prior to the main extinction. Using secondary ion mass spectrometry (SIMS), we measured oxygen isotope ratios from Changhsingian (late Permian) ostracods of north‐western Iran. Our data show that ambient seawater temperature began to rise at least 300 kyr prior to the main extinction event. Gradual warming by approximately 12°C was probably responsible for initial environmental degradation that eventually culminated in the global end‐Permian mass extinction.

Description: Continuous pollen and chironomid records from Lake Emanda (65°17′N, 135°45′E) provide new insights into the Late Quaternary environmental history of the Yana Highlands (Yakutia). Larch forest with shrubs (alders, pines, birches) dominated during the deposition of the lowermost sediments suggesting its Early Weichselian [Marine Isotope Stage (MIS) 5] age. Pollen‐ and chironomid‐based climate reconstructions suggest July temperatures (TJuly) slightly lower than modern. Gradually increasing amounts of herb pollen and cold stenotherm chironomid head capsules reflect cooler and drier environments, probably during the termination of MIS 5. TJuly dropped to 8 °C. Mostly treeless vegetation is reconstructed during MIS 3. Tundra and steppe communities dominated during MIS 2. Shrubs became common after ~14.5 ka bp but herb‐dominated habitats remained until the onset of the Holocene. Larch forests with shrub alder and dwarf birch dominated after the Holocene onset, ca. 11.7 ka bp. Decreasing amounts of shrub pollen during the Lateglacial are assigned to the Older Dryas and Younger Dryas with TJuly ~ 7.5 °C. TJuly increased up to 13 °C. Shrub stone pine was present after ~7.5 ka bp. The vegetation has been similar to modern since ca. 5.8 ka bp. Chironomid diversity and concentration in the sediments increased towards the present day, indicating the development of richer hydrobiological communities in response to the Holocene thermal maximum.

Description: Many sections are known from Iran which exhibit sediments across the Devonian-Carboniferous (D-C) boundary. In contrast to the majority of published D-C sections worldwide from pelagic/hemipelagic environments, successions in Iran are mainly composed of shallow-water sediments. Correlation with hemipelagic or pelagic palaeoenvironments remains difficult due to biostratigraphic uncertainties in most sections and/or hiatuses. On the other hand, a limited number of sections dealing with shallow-water facies settings in Iran at this particular time period are known and further research is necessary. Several sections in the Alborz Mountains provide an excellent opportunity to study successions across the D-C boundary in shallow-water facies. In Iran, protognathoids are represented by Protognathodus meischneri and Protognathodus collinsoni. The two biostratigraphically important protognathoids (Protognathodus kuehni and Protognathodus kockeli) were not reported or did not occur for the first time in the Late Tournaisian. Early siphonodellids were described instead. In the frame of an Iranian/German research project, we study different palaeoenvironments to reduce serious palaeoenvironmental and palaeogeographical sampling bias which may limit our knowledge on the Hangenberg Event particularly in shallow-water facies. We present a summary on published D-C sections in Iran (Ghale-Kalaghu, Howz-e-Dorah 1, Howz-e-Dorah 2 and Shahmirzad) and sections which are under study (Mighan, Chelcheli and Khoshyeilagh) at the time of this writing.

Description: The Dapingian to Darriwilian Kanosh Formation is one of the most fossiliferous units of the Pogonip Group (Great Basin, western US). It records a critical phase of the so-called Great Ordovician Biodiversification Event (GOBE) during which many marine clades diversified on lower systematic levels. However, a comprehensive palaeoecological analysis has not been presented for this unit so far. Based on newly collected material from three sections in the type area at Ibex, we reconstruct benthic marine communities, analyse diversity patterns, and discuss its significance for the GOBE. We find no differences in species’ composition across the formation with respect to brachiopods. Benthic assemblages are dominated by Shoshonorthis michaelis, alongside the presence of Anomalorthis lonensis and Anomalorthis utahensis across the whole unit. Trilobites show a more pronounced facies restriction with species of Kanoshia and Pseudomera being observed in more proximal limestone whereas Bathyurellus and Pseudoolenoides occur in fine-grained, low-energy deposits. The skeletal limestone also records abundant bioclasts of bryozoans, echinoderms, and receptaculitids, suggesting an ecologically diverse and tiered community being present in the inner shelf zone. However, most of these groups are not particularly diverse in terms of species richness. This implies that principle establishment of typical members of the “Palaeozoic Fauna” is not associated with a local diversification of clades. The comparably low habitat diversity of the Kanosh Fauna likely reflects environmental constraints such as high rates of siliclastic input. Additionally, these mainly Dapingian communities still represent a base-line fauna before the principal diversification took place.

Description: A Late Devonian to (?)Early Mississippian section at Hushoot Shiveetiin gol in the Baruunhuurai Terrane of the Central Asian Orogenic Belt (CAOB) exposes large parts of cyclic Famennian shallow-water siliciclastic shelf deposits composed of siltstones, sandstones, shales, volcaniclastics, and intercalated autochthonous carbonates. The youngest part of the section, possibly Early Mississippian, is represented by arkosic sandstones with large plant remains. The facies reflects a range from shallow-intertidal to outer ramp settings. In terms of conodont stratigraphy, the Hushoot Shiveetiin gol section ranges from the Palmatolepis minuta minuta Biozone to at least the Palmatolepis rugosa trachytera Biozone. Hiatuses of several conodont biozones occur due to the facies setting (erosion and reworked sediments which are recognized by reworked conodonts) rather than thrusting or folding. The environmental setting was characterized by coeval subaerial volcanism resulting in numerous pyroclastic deposits. The depositional environments and intense volcanic activity at the Hushoot Shiveetiin gol section limited the stratigraphic distribution, abundance, and diversity of many elements of the fauna such as brachiopods. Ostracods were very abundant and diverse through many parts of the section. Although limited in stratigraphic distribution, the crinoid fauna is the most diverse Palaeozoic fauna collected from Mongolia to date and supports the hypothesis that the CAOB was a biodiversity hotspot in the aftermath of the Frasnian–Famennian extinction event.

Description: Deep‐sea hydrothermal systems provide ideal conditions for prebiotic reactions and ancient metabolic pathways and, therefore, might have played a pivotal role in the emergence of life. To understand this role better, it is paramount to examine fundamental interactions between hydrothermal processes, non‐living matter, and microbial life in deep time. However, the distribution and diversity of microbial communities in ancient deep‐sea hydrothermal systems are still poorly constrained, so evolutionary, and ecological relationships remain unclear. One important reason is an insufficient understanding of the formation of diagnostic microbial biosignatures in such settings and their preservation through geological time. This contribution centers around microbial biosignatures in Precambrian deep‐sea hydrothermal sulfide deposits. Intending to provide a valuable resource for scientists from across the natural sciences whose research is concerned with the origins of life, we first introduce different types of biosignatures that can be preserved over geological timescales (rock fabrics and textures, microfossils, mineral precipitates, carbonaceous matter, trace metal, and isotope geochemical signatures). We then review selected reports of biosignatures from Precambrian deep‐sea hydrothermal sulfide deposits and discuss their geobiological significance. Our survey highlights that Precambrian hydrothermal sulfide deposits potentially encode valuable information on environmental conditions, the presence and nature of microbial life, and the complex interactions between fluids, micro‐organisms, and minerals. It further emphasizes that the geobiological interpretation of these records is challenging and requires the concerted application of analytical and experimental methods from various fields, including geology, mineralogy, geochemistry, and microbiology. Well‐orchestrated multidisciplinary studies allow us to understand the formation and preservation of microbial biosignatures in deep‐sea hydrothermal sulfide systems and thus help unravel the fundamental geobiology of ancient settings. This, in turn, is critical for reconstructing life's emergence and early evolution on Earth and the search for life elsewhere in the universe.

Description: Thirty Devonian-Carboniferous Boundary sections of the Rhenish Slate Mountains and adjacent subsurface areas are reviewed with respect to litho-, event, conodont, ammonoid, sequence, and chemostratigraphy. In the interval from the base of the uppermost Famennian (Wocklum Beds, Wocklumian) to the base of the middle Tournaisian (base Lower Alum Shale), 11 conodont and 16 ammonoid (sub)zones are distinguished. The terminology of the Hangenberg Crisis Interval is refined, with an overall regressive Crisis Prelude below the main Hangenberg Extinction, which defines the base of the transgressive Lower Crisis Interval (Hangenberg Black Shale). The glacigenic and regressive Middle Crisis Interval (Hangenberg Shale/Sandstone) is followed by the overall transgressive Upper Crisis Interval that can be subdivided into three parts (I to III) with the help of conodont stratigraphy (upper costatus-kockeli Interregnum = upper ckI, Protognathodus kockeli Zone, and lower part of Siphonodella (Eosiphonodella) sulcata s.l./Pr. kuehni Zone). Protognathodus kockeli includes currently a wide range of forms, which variabilities and precise ranges need to be established before a precise GSSP level should be selected. Returning to its original definition, the former Upper duplicata Zone is re-named as Siphonodella (S.) mehli Zone. It replaces the S. (S.) jii Zone, which is hampered by taxonomic complications. The S. (S.) quadruplicata Zone of Ji (1985) is hardly supported by Rhenish data. The entry of typical S. (S.) lobata (M1) characterises an upper subdivision (subzone) of the S. (S.) sandbergi Zone; the new S. (S.) lobata M2 enters much earlier within the S. (S.) mehli Zone. The ammonoid-defined base of the Wocklum-Stufe (Upper Devonian = UD VI) begins with the Linguaclymenia similis Zone (UD VI-A1). The oldest S. (Eosiphonodella) enter within the Muessenbiaergia bisulcata Zone (UD VI-A2). The traditional Parawocklumeria paradoxa Zone of Schindewolf (1937) is divided into successive P. paprothae (VI-C1), P. paradoxa (VI-C2), and Mayneoceras nucleus (VI-C3) Subzones. In the lower Tournaisian (Lower Carboniferous = LC I), the Gattendorfia subinvoluta Zone is subdivided into G. subinvoluta (LC I-A2) and “Eocanites” nodosus (LC I-A3) Subzones. The Paprothites dorsoplanus Zone (LC I-B) can be divided into Pap. dorsoplanus (LC I-B1) and Paragattendorfia sphaeroides (LC I-B2) Subzones. Potential subdivisions of the Pseudarietites westfalicus (LC I-C) and Parag. patens Zones (LC I-D) are less distinctive. The unfossiliferous or argillaceous upper part of the Hangenberg Limestone and the overlying Lower Alum Shale Event Interval remain regionally unzoned for ammonoids.

Description: The early Cenomanian crippsi Event comprises a 1–3-m-thick interval characterised by mass occurrences of the early Cenomanian inoceramid Gnesioceramus crippsi, identified in the uppermost Sharpeiceras schlueteri Subzone (lower lower Cenomanian Mantelliceras mantelli Zone), below an interregional sequence boundary (SB Ce 1). At Lüneburg, the event is characterised by densely packed, very large, disc-like valves of G. crippsi. Taphonomy as well as bio- and microfacies suggest an event formation in a deeper shelf setting below the storm-wave base as primary biogenic concentration, the inoceramids living as recumbent forms on a soft substrate in dense populations. When tracked between basins, the stratigraphic pattern of the crippsi Event suggests a moderately prolonged phase (〈 100 kyr) of increased shell production with rapid deposition aiding in preserving the shell-rich event strata. Towards the basin margins, it grades into storm wave-reworked bioclastic concentrations. The crippsi Event formed by an interregional population bloom and provides, as an proliferation epibole, an important marker for intra- and interbasinal correlation. The first record of G. mowriensis within the crippsi Event at Lüneburg, hitherto endemic to the US Western Interior Seaway, and the occurrence of the ammonite Metengonoceras teigenense, likewise an endemic North American faunal element, from the level of the crippsi Event in northern France indicate faunal exchange between the New and Old worlds during the early Cenomanian. This faunal dispersal and contemporaneous occurrence of warm-water biofacies in Western Europe during the early Cenomanian is explained by the existence of a perpetual NE-directed current transporting warm surface waters from the Gulf of Mexico towards Europe. The occurrence of short-lived M. teigenense in France allows for the calibration of the uppermost schlueteri Subzone of the mantelli Zone in Europe to the lowermost Neogastroplites muelleri Zone in North America and to assign an age of ~ 98.6–98.7 Ma to the crippsi Event.

Description: The siliciclastic Jhuran Formation of the Kachchh Basin, a rift basin bordering the Malagasy Seaway, documents the filling of the basin during the late syn-rift stage. The marine, more than 700-m-thick Tithonian part of the succession in the western part of the basin is composed of highly asymmetric transgressive–regressive cycles and is nearly unfossiliferous except for two intervals, the Lower Tithonian Hildoglochiceras Bed (HB) and the upper Lower Tithonian to lowermost Cretaceous Green Ammonite Beds (GAB). Both horizons represent maximum flooding zones (MFZ) and contain a rich fauna composed of ammonites and benthic macroinvertebrates. Within the HB the benthic assemblages change, concomitant with an increase in the carbonate content, from the predominantly infaunal “Lucina” rotundata to the epifaunal Actinostreon marshii and finally to the partly epifaunal, partly infaunal Eoseebachia sowerbyana assemblage. The Green Ammonite Beds are composed of three highly ferruginous beds, which are the MFZ of transgressive–regressive cycles forming the MFZ of a 3rd-order depositional sequence. The GAB are highly ferruginous, containing berthieroid ooids and grains. GAB I is characterized by the reworked Gryphaea moondanensis assemblage, GAB II by an autochthonous high-diversity assemblage dominated by the brachiopods Acanthorhynchia multistriata and Somalithyris lakhaparensis, whereas GAB III is devoid of fossils except for scarce ammonites. The GAB are interpreted to occupy different positions along an onshore–offshore transect with increasing condensation offshore. Integrated analyses of sedimentological, taphonomic, and palaeoecological data allow to reconstruct, in detail, the sequence stratigraphic architecture of sedimentary successions and to evaluate their degree of faunal condensation.

Description: A late early Maastrichtian dinosaur trampling site is reported from the Farrokhi Formation of the Khur area, Central Iran. The largely indeterminate footprints, some of which may represent undertracks, can be classified as natural moulds (i.e. concave epireliefs) bordered by a raised rim of displaced sediment. They reach diameters of up to 0.5 m and were impressed under very shallow to subaerial conditions in an inter- to supratidal environment. Two generations of traces have been imprinted, initially into a soft, fine-grained carbonate sand and afterwards into a superficially hardened substrate that was still plastic underneath; the change in substrate consistency is supported by a conspicuous cracking pattern around the footprints. As a result, hardly any details of the foot morphology of the trackmakers are recorded. Nevertheless, the occurrence improves our knowledge about dinoturbation and its preservation in different kinds of substrates. Furthermore, it is the youngest record (ca. 70 Ma) of dinosaur locomotion traces from Iran and, in all probability, the entire Middle East.

Description: At the beginning of Late Jurassic both the Lochen (LA) and the Cracow areas (CA) were palaeotopographic highs in an epicontinental basin located at the stable northern margin of the Tethyan Ocean. The topographically high position of the LA was probably caused by intensive carbonate production which proceeded on a small sea-floor bulge located close to the boundary between middle and lower parts of the low-angle carbonate ramp. Lack of deep structural control of this rise caused prograding facial unification during the Oxfordian and Kimmeridgian and led to gradual disappearance of the LA individuality in relation to the neighbouring areas. The topographical high of the CA resulted from anomalously low subsidence rate in comparison to the adjacent areas which has lasted at least for the whole Oxfordian. Low subsidence directly gave rise to the development of a barrier (so-called Cracovian Platform) which separated the interior basin in the north from the deeper parts of the basin in the south. Topography of the Polish part of epicontinental basin along the Czestochowa-Cracow line corresponds to the low-gradient rimmed carbonate shelf which graded laterally (to the northeast and east) into the low-angle carbonate ramp. Stratigraphic subdivision of Upper Jurassic strata is very precise in the LA and rather poor in the CA due to scarcity of ammonites in the massive facies which predominates in the latter area. However, ammonite fauna from both areas belongs to the same German-Polish Submediterranean Subprovince which allows to attempt the correlation of lithologies and determination of factors which controlled deposition. Both the studied areas show distinct differences in the development of carbonate buildups. In the LA the main components of carbonate buildups during whole Oxfordian and the Early Kimmeridgian were siliceous sponges and microbolites whilst in the CA the flourishing growth of microbolites and gradual decline of siliceous sponges domination took place during the Late Oxfordian. The sediment was initially diversified into the two varieties: that formed by siliceous sponges and the microbolites incipient rigid framework, and the soft mud. In such carbonate buildups stromatactis cavities might have developed even in early diagenesis due to internal erosion of the soft mud. The principal reason of the internal erosion was turbulent water flow through the sediment. However, in generally low-energy sedimentary environments such flow could be triggered by submarine gravity flows or strong bottom currents. Pseudonodular textures encountered in carbonate buildups in both the areas resulted from shallow-burial diagenesis. During the burial diagenesis some parts of the sediment has been disintegrated under the pressure of overlying strata owing to the existing open spaces and different susceptibility to compaction showed by the incipient rigid framework and the soft sediment. Deposition in the LA was controlled mainly by sea-level pulses and ecological factors. In the CA principal control was provided by subsidence rate supported by synsedimentary tectonics, sea-level changes and ecological factors. All these controlling factors were variable in time which provoked changes in carbonate production rates from intensive, aggradational growth of the buildups to drowning of the carbonate ramp and rimmed shelf. The drowning of carbonate ramp on which the LA was located took place at the Oxfordian/Kimmeridgian break. It is documented by spectacular development of redeposited pelagites of skeletal-calciturbidites type with abundant fragments of Saccocoma sp. which have appeared for the first time in mass quantities in the Upper Jurassic. By analogy, it can be inferred that in the CA similar Saccocoma-calciturbidites prove the drowning of rimmed shelf related to the same trangressive event at the Oxfordian/Kimmeridgian break.

Description: Zu Beginn des Ober-Jura waren das Lochengebiet (Schwäbische Alb) und der Raum Krakau (Südpolen) übereinstimmend Hochgebiete eines epikontinentalen Beckens auf dem passiven nördlichen Schelf der Tethys. Die topographische Hochposition des Lochengebietes war vermutlich durch eine hohe Karbonat-Produktion bedingt, welche auf einer schmalen submarinen Schwelle nahe dem Übergangsbereich zwischen unterem und mittlerem Abschnitt einer flach geneigten Karbonatrampe erfolgte. Während des Oxfordiums und Kimmeridgiums war die Lochenschwelle tektonisch inaktiv und ermöglichte einen zunehmenden Faziesausgleich mit den benachbarten Gebieten und führte dadurch zu einer successiven Aufgabe ihrer individuellen Entwicklung. Die Hochposition der Krakau-Region resultierte aus ihrer im Vergleich zur Umgebung ungewöhnlich geringen Subsidenzrate, welche mindestens während des gesamten Oxfordiums anhielt. Die geringe Subsidenz war unmittelbare Ursache für die Entwicklung einer Barriere (die sogenannte Krakau-Plattform), welche das seichtere Innenschelf-Becken im Norden von den tieferen Beckenanteilen im Süden trennte. Die Topographie des polnischen Anteils dieses epikontinentalen Beckens entsprach entlang der Czestochowa-Krakau-Linie einem „low-gradient rimmed carbonate shelf, der nach Nordosten und Osten lateral in eine flache Karbonatrampe überging. Die stratigraphische Gliederungsmöglichkeit der Ober-Jura-Schichfolge ist im Lochengebiet gut und feinauflösend, in der Krakau-Region dagegen, in der die Massenfazies vorherrscht, aufgrund der selteneren Ammonitenfunde zum Teil problematisch. Ungeachtet dessen, gehören die Ammoniten-Vergesellschaftungen beider Regionen derselben deutsch-polnischen, submediterranen Faunensubprovinz an und ermutigen zu einer Korrelation beider lithologischer Abfolgen und einer vergleichenden Abstraktion der Steuermechanismen für die Sedimentation. Beide Gebiete zeigen deutliche Unterschiede in der Entwicklung von karbonatischen Buildups. Im Lochen-Gebiet stellen während des Oxfordiums und Unter-Kimmeridgiums Kieselschwämme und Mikrobolithe die Hauptkomponenten der Riffstrukturen, während in der Krakau-Region die Bedeutung der Mikrobolithe und Kieselschwämme während des Ober-Oxfordiums successive abnimmt. Ursprünglich erfolgte eine Differenzierung der Riffstrukturen in einen autochthonen Hartsubstrat-Anteil, in dem Kieselschwämme und Mikrobolithe eine rigides Gerüst stellten, und in schlammiges Weichsubstrat. Innerhalb der Riffkörper konnten sich wohl frühdiagenetisch durch die interne Erosion der Schlamm-Anteile Stromatactis-Gefüge bilden. Grundsätzlich kann eine solche interne Erosion auf turbulente Porenwasserströme zurückgeführt werden. In den vorliegenden sedimentären Stillwasser-Milieus könnte ein solcher Porenwasserstrom durch submarine Schuttströme oder starke Bodenströmungen ausgelöst worden sein. Pseudonodulare Strukturen, wie sie in den Buildups beider Untersuchungsgebiete angetroffen wurden, werden durch eine flache Versenkungsdiagenese erklärt. Während dieser Vorgänge wurden unter dem Druck der Sedimentauflast aufgrund des vorhandenen, offenen Porenraumes und der unterschiedlichen Kompaktion von primär zementierten Riffkalken und des mergeligen Weichsubstrates Karbonatanteile gelöst. Das Sedimentationsgeschehen wurde in der Lochen-Region vor allem durch Meeresspiegel-Schwankungen und ökologische Parameter beeinflußt. In der Krakau-Region konnte als hauptsächlicher Kontrollfaktor die Subsidenzrate erkannt werden, in deren Gefolge synsedimentäre Tektonik, Änderungen von Meeresspiegel und der ökologischen Faktoren einhergingen. Veränderungen dieser Steuerfaktoren in der Zeit beeinflußten jeweils die Rate der Karbonatproduktion von intensiv (Aggradation der Buildups) bis zum Ertrinken der Karbonatrampe bzw. des Schelfrandes. Das Abtauchen der Karbonatrampe setzte in der Lochen-Region an der Oxfordium-Kimmeridgium-Wende ein. Es wird durch eine auffällige sedimentäre Entwicklung dokumentiert: Resedimentation pelagischer Kalke (skeletal calciturbidites), die häufig Saccocoma-Reste enthalten. Erste Massenvorkommen von Saccocoma treten in der Erdgeschichte im Oberjura auf. Ähnliche Saccoco/na-Kalkturbidite an der Oxfordium-Kimmeridgium-Grenze markieren in der Krakau-Region das Abtauchen des „rimmed shelf. Sie können auf dasselbe transgressive Ereignis zurückgeführt werden.

Description: The present study considered calcareous nannofossils from material represented by outcrops of Flysch successions of the External Hellenides belt in the area of the Ionian Zone (I.Z.), northwestern Greece. The studied outcrops are located in Epirus mainland and the Ionian island Korfu. Three subdivisions have been traditionally in literature distinguished in the I.Z., the Internal, Middle and External (moving from east to the west), each of which was subsequently recognized in the Flysch deposits as well. Aim of the study was, a refinement of the current biostratigraphic resolution of the area through detailed taxonomic descriptions and consequently, a reliably better correlation of the investigated sedimentary deposits with the help of calcareous nannofossils. The biostratigraphic data were also processed semiquentitatively (frequency variations and distributions), in order to accurately determine important biohorizons. For this purpose, the nannofossils were studied under the LM and the SEM, from ten closely sampled sections representing clastic sequences of all the three subdivisions of the I.Z. The investigated sections are situated at about 39° northern mid latitudes, a fact which resulted to mixed nannoflora assemblages of low and high latitudes character. The sections are namely: Elatos, Korfovouni (Internal I.Z. subdivision), Kato Despotiko, Strouga Goumenou and Ekklisia (Middle I.Z. subdivision), lower and upper Argyrotopos, National Road, Monos and Anacharavi (External I.Z. subdivision). They were found to range in age from the latest Eocene to the Early Miocene. Based on the systematic palaeontology, 107 species of calcareous nannofossils were observed and documented in the studied material. Among them, a new species Rhabdosphaera epirotica sp. nov. was described, and four recombinations were proposed. Moreover, two calcareous dinoflagellate cysts, Cervisiella saxea and Obliquipithonella sp. were reported for the first time from the I.Z. in Greece. Despite the mid latitude palaeogeographic position of the sections, all the conventional calcareous nannofossil zonal markers for the Oligocene and Early Miocene were recorded, although some in fewer abundances than in low latitudes. Improving the biostratigraphic reliability, a new zonational scheme was here developed and proposed for the Oligocene to Early Miocene interval. It was mainly established on use of redefined biohorizons and composed of five zones and five subzones following below: 1. Latest Eocene: Ericsonia formosa Partial-range Zone, 2. Oligocene: llselithina fusa / Ericsonia formosa Concurrent-range Zone, Ericsonia formosa-Reticulofenestra umbilicus/R. hillae Interval Zone, Cyclicargolithus abisectus Partial-range Zone, including the subzones: Rhabdosphaera spp. Interval Subzone, and Sphenolithus predistentus Interval Subzone, Reticulofenestra scissura Interval Zone, including the Sphenolithus delphix Abundance Subzone, and 3. Earliest Miocene: Triquetrorhabdulus spp. Partial-range Subzone Sphenolithus conicus Interval Subzone. Based on a new biohorizon of the absolute First Occurrence (FO) of llselithina fusa, the Eocene/Oligocene (E/O) boundary was identified in the lower part of the Argyrotopos section. On the absence of disc-shaped discoasters, the I. fusa biohorizon represented a better approximation of the boundary, which was clearly correlated with the other studied sections of the three subdivisions of the I.Z. The Oligocene/Miocene (O/M) boundary was identified in the Monos section located in the Plataria syncline (External I.Z.), but Early Miocene strata were recorded in the Middle I.Z. as well. This boundary was placed at the Last Common Occurrence (LCO) biohorizon of the Reticulofenestra scissura. Moreover, six associate bioevents were reported near the O/M boundary, among them the highest occurrence of I. fusa, located above the boundary, in the Anacharavi section of Korfu island (western part of the External I.Z.). For the first time were evaluated reworked together with „autochton“ taxa of calcareous nannofossils in Greece. Maximum diversity values along each of the studied sections, have shown increased reworking and erosional processes in the Internal subdivision of the I.Z. than in the Middle and the External ones. This is interpreted to be connected with the higher tectonic instability along the Pindos thrust to the east, in relation to the central and western parts of the Ionian basin mainly during the Oligocene.

Description: Die der vorliegenden Arbeit zugrundeliegenden kalkigen Nannofossilien stammen von Flyschabfolgen der Externen Helleniden (Ionische Zone) Nordwest-Griechenlands.So wurden in die Untersuchung Aufschlüsse des Festlandes in Epirus und der Ionischen Insel Korfu aus dem stratigraphischen Intervall vom obersten Eozän bis zum untersten Miozän einbezogen. Die Ionische Zone (I.Z.) wird traditionell von Osten nach Westen in die Interne, Mittlere und Externe Subzone unterteilt. Diese Einteilung läßt sich auch auf die Flyschablagerungen übertragen. Ziel der Arbeit ist eine Verfeinerung der bestehenden Biostratigraphie durch detaillierte taxonomische Beschreibungen, um damit eine bessere Korrelation der untersuchten Ablagerungen mit Hilfe der kalkigen Nannofossilien zu erreichen. Mit einer halbquantitativen Erfassung der biostratigraphischen Daten (Häufigkeitsvariation und -Verteilung) gelingt es darüberhinaus, einzelne Biohorizonte genauer zu definieren. Zu diesem Zwecke wurde das kalkige Nannoplankton von zehn eng-beprobten Profilen aus klastischen Abfolgen aller drei Subzonen der I. Z. unter dem Licht- und Elektronenmikroskop (REM) untersucht. Die Profile im einzelnen sind: Elatos und Korfovouni (Interne Subzone), Kato Despotiko, Strouga Goumenou und Ekklisia (Mittlere Subzone), Unter bzw. Ober Argyrotopos, National Road, Monos und Anacharavi (Externe Subzone). Zur Ablagerungszeit befanden sich die untersuchten Profile in einer nördlichen Paläobreite um 39°, was zu einer gemischten Nannoflora aus charakteristischen Vertretern niedriger und höherer Breiten führte. In dem untersuchten Material konnten insgesamt 107 Spezies von kalkigem Nannoplankton gefunden und dokumentiert werden. Die Art Rhabdosphaera epirotica nov. sp.wird neu beschrieben und vier Rekombinationen werden vorgeschlagen. Darüberhinaus konnten zwei kalkige Dinoflagellatenzysten Cervisiella saxea und Obliquipithonella sp. zum ersten Mal in der I.Z. nachgewiesen werden. Trotz der paläogeographischen Position der Profile in mittleren Paläobreitenbereich konnten alle konventionellen Zonenleitformen des kalkigen Nannoplanktons für das Oligozän und das Untermiozän gefunden werden, einige davon jedoch in geringerer Häufigkeit als in den niedrigeren Breiten. Durch die Verbesserung der biostratigraphischen Genauigkeit wird hier ein neues mediterranes Zonenschema für das Oligozän und das Untermiozän entwickelt, das im wesentlichen auf neu definierten Biohorizonten basiert. Es enthält fünf Zonen und fünf Subzonen: 1. Jüngstes Eozän: Ericsonia formosa Partial-range Zone, 2. Oligozän: llselithina fusa/Ericsonia formosa Concurrent-range Zone, Ericsonia formosa-Reticulofenestra umbilicus/R. hillae Interval Zone, Cyclicargolithus abisectus Partial-range Zone, gegliedert in den Subzonen: Rhabdosphaera spp. Interval Subzone, und Sphenolithus predistentus Interval Subzone, Reticulofenestra scissura Interval Zone, die eine Subzone enthält: Sphenolithus delphix Abundance Subzone, und 3. Ältestes Miozän: Triquetrorhabdulus spp. Partial-range Subzone Sphenolithus conicus Interval Subzone. Mit dem ersten Auftreten (FO) von llselithina fusa wird ein neuer Biohorizont definiert, mit dem die Grenze Eozän/Oligozän (E/O) in dem unteren Teil des Argyrotopos-Profils nachgewiesen wird. Trotz der Abwesenheit von scheibenförmigen Discoasteriden läßt sich nun diese Grenze mit dem I. fusa-Biohorizont besser fassen und kann eindeutig mit den Profilen in den beiden anderen Subzonen der I.Z. korreliert werden. Die Oligozän/Miozän-Grenze (O/M) konnte im Monos-Profil der Plataria-Synklinale (Externe I.Z.) charakterisiert werden. Untermiozän ließ sich aber auch in der Mittleren Subzone nachweisen. Die Grenze O/M ist durch das letzte Vorkommen (LCO) von Reticulofenestra scissura bestimmt. Sechs assoziierte Bioevents fallen in diesen Grenzbereich, darunter im Anacharavi-Profil der Insel Korfu (Westteil der Externen Subzone) das jüngste Vorkommen von I. fusa, unmittelbar über der Grenze O/M. Zum erstem Mal für Griechenland konnten aufgearbeitete Taxa von kalkigen Nannofossilien zusammen mit den autochthonen Taxa nachgewiesen werden. Ein Vergleich der maximalen Diversitätswerte in den untersuchten Profilen zeigt eine signifikant höhere Aufarbeitungsrate in der Internen Subzone gegenüber der Mittleren und Externen Subzonen. Dieser Umstand dürfte mit der höheren tektonischen Instabilität entlang der Pindos-Decken-Front im Osten des Arbeitsgebietes Zusammenhängen.

Description: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉ABSTRACT〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉Pleistocene faunal assemblages are often highly fragmented, hindering taxonomic identifications and interpretive potentials. In this paper, we apply four different methodologies to morphologically unidentifiable bone fragments from the Neanderthal open‐air site of Salzgitter‐Lebenstedt (Germany). First, we recorded zooarchaeological attributes for all 1362 unidentifiable bones recovered in 1977. Second, we applied zooarchaeology by mass spectrometry (ZooMS) to 761 fragments, and calculated glutamine deamidation values. Third, we assessed the collagen preservation of 30 fragments by near‐infrared spectroscopy (NIR) and, finally, we pretreated 10 bones with high predicted collagen values for radiocarbon dating. All returned dates at, or beyond, the limit of radiocarbon dating, indicating an age of older than 51 000 years ago. The ZooMS faunal spectrum confirms a cold environment, dominated by reindeer, alongside mammoth, horse and bison. The low occurrence of carnivore modifications (1%) contrasts with an abundance of human modifications (23%). Cut marks and marrow fractures were observed across reindeer, horse and bison. The mammoth remains are less well preserved and show a lower degree of human modifications, indicating, perhaps, a different taphonomic history. Overall, this study illustrates the importance of retaining, studying and incorporating the unidentifiable bone fraction to optimize interpretations of site formation and subsistence behaviour at Palaeolithic sites.〈/p〉

Description: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉ABSTRACT〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉The Permian–Triassic and Triassic–Jurassic critical intervals are among the most significant ecological upheavals in the Phanerozoic. Both evolutionary junctures are characterized by environmental deterioration associated with a marked biodiversity decline. In this study, Permian–Triassic and Triassic–Jurassic boundary sections from South China and the Northern Calcareous Alps were investigated. In order to reconstruct the interplay between biotic and abiotic processes, a multifaceted approach that included optical microscopy, X‐ray diffraction, Raman spectroscopy, stable carbon isotopes and lipid biomarkers was employed. The lower parts of these two sections are similar as both consist of limestone with abundant fossils of eukaryotic organisms. However, the Permian–Triassic record is dominated by dasyclad green algae and fusulinid foraminifera, while the Triassic–Jurassic record is typified by corals and coralline sponges. Moving upward, both sections consist mainly of micrite and marl. Concerning the Permian–Triassic section, it transits to volcanic ash intercalated by a distinct limestone bed with abundant calcispheres (tentatively attributed to ancestors of dinoflagellates). The Triassic–Jurassic section does not provide direct evidence for volcanic activity, but also becomes rich in calcisphere‐type cysts towards the top. Additionally, the section preserves abundant 4‐methyl sterenes (diagnostic for dinoflagellates) and C〈sub〉37–39〈/sub〉 〈italic toggle="no"〉n〈/italic〉‐alkanes (indicative for haptophytes). Hence, both critical intervals were associated with marked blooms of (ancestral) dinoflagellates and haptophytes (for example, coccolithophorids). These blooms were followed by ecological lag‐phases, as indicated by low carbonate contents and scarce fossils which only increased further up the sections. For both critical intervals, it is commonly assumed that the formation of voluminous volcanic provinces (Siberian Traps and Central Atlantic Magmatic Province, respectively), as well as associated processes (for example, burning of organic‐rich sediments such as coal), resulted in ecological devastation. However, results suggest that volcanism also had a positive effect on certain planktonic primary producers such as dinoflagellates and haptophytes, perhaps by delivering essential nutrients.〈/p〉

Description: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉Snow petrels (〈italic〉Pagodroma nivea〈/italic〉), which are endemic to the Antarctic region, produce proventricular stomach oil from ingested food for feeding purposes but also spit the oil in the immediate surrounds of the nests, where it forms encrustations over time (Antarctic mumiyo). These deposits provide a unique opportunity to understand the paleo‐ecological diet of snow petrels and because the seabirds forage in the ocean, they potentially provide an archive of past marine environmental conditions in the Southern Ocean. For validating methods for reconstructions we use compositional data obtained on modern stomach oils and DNA data from fecal samples of snow petrels. We find that the distribution of carboxylic acid compounds in modern stomach oils and in the fossil deposits are consistent with variable contributions of fish and krill, which are the main constituents of modern snow petrel diet, and allows inference of past changes in snow petrel diet from the fossil record. Analyses of mumiyo deposits from six regions in East Antarctica reveal systematic differences in the isotopic composition of organic matter (δ〈sup〉13〈/sup〉C and δ〈sup〉15〈/sup〉N) and carboxylic acid patterns. This may suggest regional and/or temporal variability in the composition of snow petrels diet, likely differing in response to the prevailing environmental conditions in the foraging range of the birds, such as sea‐ice variability, polynya activity and primary productivity. Our study provides confidence for using these approaches for broader scale paleo‐studies in the future and for an assessment of the temporal changes and regional variability in snow petrel diet.〈/p〉

Description: Plain Language Summary: To better understand interactions of biological and physical processes in Antarctic marine ecosystems, we investigate fossil deposits of stomach oil of snow petrels for their use as a geological archive for past environmental changes. The deposits form over time in the surroundings of the nesting cavities of snow petrels, which produce stomach oil from ingested food but also spit it at nest robbers. In fresh oil the lipid and isotopic composition can be traced back to the composition of snow petrel food, such as variable proportions of fish and krill. From comparing the lipid and δ〈sup〉13〈/sup〉C‐isotopic composition of modern oil to fossil deposits we suggest it is possible to identify changes in the diet of snow petrels in the fossil record. Since the composition of the diet is closely linked to the prevailing environmental conditions in the marine foraging region of the birds, such as summer sea ice extent, this information can be used for paleoenvironmental reconstructions. Our study of deposits from widely separated regions in Antarctica shows that there are spatial and temporal differences in the composition of stomach oil deposits, likely related to the prevailing environmental conditions. This finding underpins the application of our approach.〈/p〉
