Summary: Loose limestone blocks of a newly recognized hydrocarbon-seep deposit were found on a beach in Washington State, USA. The limestone contains authigenic carbonate phases and molecular fossils of anaerobic methanotrophic archaea, indicating formation at an ancient methane seep. The fossil inventory of the seep deposit consists mainly of echinoid remains, resembling those in an upper Jurassic seep deposit in France and modern seeps in the Gulf of Mexico.

Summary: This study describes 51 fossil shark teeth, including Hexanchiformes, Echinorhiniformes, Squaliformes, and Lamniformes, from two localities in Hokkaido, Japan. The presence of Protosqualus in the northwestern Pacific suggests the early Campanian onset of deep-water adaptation for Squaliformes in this region. Different sedimentary settings at the two localities may have influenced the taxonomic compositions. The co-existence of Hexanchiformes and Lamniformes in contemporaneous Japanese fauna and southern high latitudes indicates the paleogeographic effects on the global distribution of Upper Cretaceous neoselachian taxa.

Summary: This study investigates the hydrogeological regime and structural evolution of the Cretaceous subduction zone in Hokkaido, Japan, by analyzing the timing and migration pathways of fluids emitted at ancient methane seeps. Results show that two fluid discharge events occurred during the accretionary stages, originating from the forearc basin rather than the underplating materials. The seeping fluids experienced interactions with the mafic rocks of the lower Sorachi ophiolite and siliciclastic sediments of the Yezo Group.

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.

Summary: Shoreface deltaic depositional systems form excellent stratigraphic traps that are developed under adverse sea-level conditions, impacting the quantitative prediction of stratigraphic reservoirs. The thin-bedded reservoirs require specific tuning frequencies for accurate thickness and distribution, with band-limited seismic attributes not being reliable tools for cost-effective stratigraphic plays. Continuous wavelet transforms and thickness modeling have been used to enhance the prediction of reservoir thickness and presence of hydrocarbons along UDS.

Summary: Recent discoveries in southern South America have improved the Late Cretaceous dinosaur record, with findings from Chorrillo and Cerro Fortaleza formations adding ankylosaur remains to the previously recorded dinosaur fauna. A site in Cerro Fortaleza Formation yielded isolated teeth and osteoderms from Abelisauridae, Titanosauria, Nodosauridae, and Peirosauridae, providing valuable information on the biodiversity of the region during the Campanian-Maastrichtian age. This site also marks the first record of ankylosaurs and the most southerly record of Peirosauridae in South America.

Summary: This study investigates the tectonic evolution and provenance characteristics of the late Paleozoic to early Mesozoic collision-related orogeny in Japan using morphological analysis and U-Pb ages of detrital zircons. The results show that the late Paleozoic zircons were derived from nearby sources, while the pre-late Paleozoic zircons were supplied from distant sources under strong hydrodynamic conditions. Combining the geological information of East Asia, the study reveals a change in sources from the Southern zone of the Maizuru Belt to multiple areas, supporting the collision of the island arc and continental margin of the Sino-Korean Block during the middle Permian.

Summary: The study describes the discovery of Goniodromites sp. (Brachyura: Dromiacea: Goniodromitidae) in the Cenomanian (Upper Cretaceous) cold seep sediment of the Middle Yezo Group in Hokkaido, Japan. This represents the first recognition of the genus and family in Cretaceous chemosynthetic communities, as well as the second record of a decapod from fossil chemosynthetic communities in Japan. Additionally, the poorly known goniodromitid crab Sabellidromites inflata (Collins and Karasawa, 1993) is redescribed.

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: The study discusses the evolution of Thecideide brachiopods from the Triassic to the Holocene based on microstructure and texture measurements. Different mineral units were observed in the shells of Thecideide brachiopods from fossil and Recent specimens, showing variations in characteristics over time. The changes in microstructure and texture are attributed to adaptions to different habitats and lifestyles associated with cementation to hard substrates.

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: Research on the global distribution of living brachiopods and the proposal of a global bioregionalization framework highlighted the driving factors of large-scale ocean gyres, climatic zonation, and geohistorical factors. At a regional scale, faunal composition, diversity, and biogeographical differentiation are mainly controlled by seawater temperature variation, regional ocean currents, and coastal upwelling systems.

Summary: Based on the latest global database of living brachiopods, this study found that about 59% of brachiopod species have smooth shells and there is no statistically significant linear trend between shell ornamentation index, latitudes, and water depths. These findings contrast with the patterns observed in fossil brachiopods and can be attributed to various factors including habitat selection and adaptation strategies rather than predation pressure.

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.
