Summary: The first record of Erymnocerites Jeannet genus from Poland is presented. A single specimen assigned to Erymnocerites argoviensis Jeannet was found in the Callovian Lamberti Zone at the Ogrodzieniec quarry in southern Poland. It was found in association with upper Callovian forms of other fossils. The specimen differs from the middle Callovian Coronatum Zone E. argoviensis but is referred to as the same species based on septal suture line and ribbing pattern.

Summary: The contribution presents new records and describes nine other nautiloid species from various geological sections in southern Poland. The study provides precise age-constrained data on nautiloid occurrences based on co-occurring ammonites, refining the biostratigraphy of the studied sections. Several new species are reported, along with important stratigraphic information on previously known species. Furthermore, a new occurrence of a nautiloid species is reported from western India.

Summary: Crinoids are considered good indicators for determining environmental conditions, with their distribution being strongly substrate-dependent but showing weak significance for palaeodepth. The qualitative data and statistical analysis based on crinoid occurrences in Poland suggest that different crinoid groups prefer different substrate types and depths, with some exceptions of cosmopolitan taxa.

Summary: This research reveals the climate changes during the Middle Jurassic period, which included oscillations between semiarid-subhumid, arid-humid, and cool/warm-temperate climates on land. The fluctuations in climate were possibly linked to global geological events and regional tectonic uplift. The findings also suggest relatively low CO2 levels during this period, coinciding with the threshold for glacial initiation and explaining cool intervals in a warm Jurassic era.

Summary: The study reveals significant fluctuations in seawater temperature during the Jurassic period, with different regions showing varying degrees of temperature decrease. The carbon isotope trends are consistent with previously identified phases of environmental perturbation. The cooling is believed to be a result of enhanced carbon burial and reduced atmospheric carbon dioxide. The study is limited by its focus on a single region in southern England.

Summary: This study revisits the rare Middle Jurassic ammonite Oecoptychius refractus and finds its main occurrence in the Callovian Kosmoceras Zone and Quenstedtoceras Zone, with large morphological variation in body-chamber shape. The fossil record of O. refractus is better documented in the western Tethys (Poland, Germany, and France) compared to the eastern Tethys (Madagascar and India). The extensive palaeobiogeographic range of O. refractus may be influenced by recurrent sea level rises in the Middle Jurassic.

Summary: The facies variability of mudstones may be greater than previously perceived, which has significant implications for their behavior in engineering, energy, and waste disposal applications. This study focuses on the UK Oxford Clay, a well-studied mudstone from the Middle/Upper Jurassic period. Through a combination of wire-line logs, geochemistry, sequence stratigraphy, and biofacies analyses, the research reveals the heterogeneity within the Peterborough Member of the Oxford Clay and investigates how it responded to basin features. The findings suggest a complex patchwork of environments influenced by local basin settings, cautioning against developing basin-scale models based solely on a limited number of well-exposed outcrop successions.

Summary: This study describes the terebratulide brachiopods from the Middle Jurassic period in the Jordan Valley and identifies a new taxon. Several terebratulide taxa were found in the Callovian rocks of the Tel el Dhahab section, including both known species and a newly described species. The study also provides insights into the shell microstructure and internal characters of these terebratulide brachiopods and discusses their paleobiogeographic interpretation.

Summary: This study explores the heterogeneity and environmental diversity within the Oxford Clay in the UK and highlights its significant implications for civil engineering, energy, and waste disposal applications. The results reveal pronounced variations in thickness and biofacies patterns of the Oxford Clay across different basin settings, cautioning against developing basin-scale models based on limited outcrop successions.

Summary: The Middle Jurassic fauna from Sainte-Scolasse-sur-Sarthe in France has remarkably preserved crustaceans in limestone beds. The crustacean fauna includes five species, with the Glypheidae lobsters being the most diverse and abundant group. A detailed anatomical description has allowed for the reconstruction of Glyphea dressieri and the identification of a marked sexual dimorphism. Quantitative analysis of 149 specimens shows that Glyphea regleyana and G. dressieri are the dominant species.

Summary: The Middle Jurassic terebratulide brachiopods from the Jordan Valley were revised and new taxa were added to the previous faunal list. The study identified two new terebratulide taxa and reported three terebratulide species for the first time in Jordan, showing a correlation with more widespread taxa in the Ethiopian Province. The high degree of endemism of the terebratulide brachiopods in this study confirms the pronounced Middle Jurassic endemism along the southern Tethyan margin of the Ethiopian Province.

Summary: Body size is an important trait that has implications for energy use, ecology, and evolutionary rates. This study examined the body-size change in turritelline gastropods and found that their size was inversely correlated with latitude, likely due to the diversification of small-bodied Southern Hemisphere taxa. The study also revealed that turritelline gastropods have experienced stasis in body size throughout their evolutionary history.

Summary: Owadow-Brzezinki is an important Upper Jurassic site in Central Poland, known for its diverse fossil fauna including large marine reptiles. In this report, four isolated teeth with distinct features of plesiosaurians were discovered, confirming the presence of Plesiosauroidea in the Owadow-Brzezinki Lagerstatte. This finding highlights the significance of the site as a mix zone between different faunas and expands the range of fossil taxa found in the area.

Summary: This study conducted a detailed palynomorph and palynofacies analysis of the Middle Jurassic Khatatba Formation in the Dahab-Mireir Basin, revealing moderately diverse palynomorph assemblage and palynofacies. The findings provide insights into different depositional environments and relative sea level changes, which are of significant importance for understanding basin history, reservoirs, and source rock units.

Summary: The studied seep carbonates from Tsushima, Japan, represent the earliest evidence of hydrocarbon seepage in the Sea of Japan, forming within a pull-apart basin before major anticlines had formed. The carbonates are primarily composed of calcite, with significant admixture of ankerite at Kanoura, and isotopic analysis indicates methanogenic origin.

Summary: Modern hydrothermal vent communities are supported by microbial primary producers, with many dominant taxa emerging during the Cenozoic and Cretaceous periods. Fossil records of vent communities from these time periods are scarce. A discovery of Cretaceous vent communities in Cyprus reveals a diversity of new species in gastropods, with shared tube worms among vent sites in the western Neotethyan Ocean.

Summary: This study reports the discovery of the first cephalopod statoliths from the Early Cretaceous, filling the gap in the fossil record between Jurassic and Cenozoic forms. The statoliths show a closer resemblance to the Recent Idiosepiidae and are suggested to belong to the basal decabrachians. The robustly developed spur in the Mesozoic statoliths may play a similar role to the wing in Cenozoic and Recent decabrachians. The abundance ratio of statoliths vs fish otoliths also supports a Cretaceous turnover in marine organisms.

Summary: Studies on the involvement of intrusive magmatism in hydrocarbon generation within sedimentary basins have gained momentum due to the increasing appraisal of their role in controlling global carbon cycle perturbations and the exploration potential of volcanic sedimentary basins. A multi-proxy geochemical study in the Basque-Cantabrian Basin during the middle Cretaceous revealed radiogenic Nd isotope signals in methane-seep deposits, indicating a connection between hydrocarbon seepage and igneous activity, and demonstrating the potential of Nd isotopes in tracing magmatic-influenced fluids in volcanic sedimentary basins.
