Summary: Our study investigates two new fish-dominated faunas from the Middle Triassic in Poland and compares them to vertebrate assemblages from the Germanic Basin to examine the impact of salinity on species composition. Our analysis reveals that the composition of the faunas in dolomite beds is similar to the Muschalkalk facies, while the faunas in glauconite beds represent the first brackish vertebrate assemblage in the Serrolepis lake-type found in the eastern Germanic Basin. Through hierarchical clustering, nonmetric multidimensional scaling, and principal component approaches, we identify freshwater, brackish, marine, and euryhaline vertebrate taxa across all sites. We confirm the brackish nature of the Serrolepis-bearing assemblages and suggest that Serrolepis suevicus is a specialist species indicating oligohaline to miohaline paleosalinities. The Middle-Late Triassic vertebrate faunas are primarily dominated by stenohaline taxa, with a separation between species living in freshwater and marine conditions. Euryhaline taxa are rare and include Acrodus lateralis, Eusauropterygia, Lissodus nodosus, and Saurichthyiformes.

Summary: The Upper Triassic conodont genus Primatella is significant for identifying the Carnian-Norian stage boundary in the Panthalassan and Tethyan regions. The occurrence and distribution of two key species, P. asymmetrica and P. bifida, in various regions, including North American Cordillera, Great Basin, western Tethys, and Timor-Leste, are documented. However, the differing nomenclature in Tethyan regions has complicated the correlation potential of Primatella species, thereby impacting their stratigraphic utility.

Summary: This paper presents the first attempt to develop the facies model of the entire Carboniferous coal deposit in the western part of the Upper Silesian Coal Basin. The study reveals the sedimentological evolution and facies development of the Knur coal deposit, indicating the influence of the river system and the correlation between fault occurrence and coal facies.

Summary: Fossil plant assemblage from the Norian Grabowa Formation in southern Poland indicates low plant diversity compared to Carnian and Rhaetian flo-ras. The presence of gymnosperms and sphenophytes suggests variation in local conditions.

Summary: Based on detailed sedimentological and palaeosol analysis, this study characterizes the depositional environment and climate evolution from the late Permian to the early Middle Triassic. The results show that the late Permian in Morocco was dominated by a distal fluvial fan environment under arid to semi-arid conditions, while the early Triassic featured aeolian deflation lag, debris flow lobes, and sheetflood ephemeral alluvial fan deposits. The Marrakech High Atlas basins were characterized by well-developed aeolian dunes in an alluvial fan environment. The study also finds that there was a common climate evolution in Morocco during the Lower Triassic until a newly defined angular unconformity.

Summary: The eastern sector of the Mesozoic Iberian basin belongs to the 'Mediterranean type' Triassic, characterized by a stratigraphic record with two carbonate Muschelkalk units. The evolution of the platform morphology from an epicontinental platform to a lower energy rimmed shelf is depicted through the deposition of shallow-water carbonates and tidal/lagoon environments.

Summary: This study presents new research on ground-motion relations in three areas of the Upper Silesia Coal Basin (USCB) in Poland, aiming to better predict ground motion caused by seismic events. By comparing results with previous models and using regression models, the study explores the influence of geology on ground motion, particularly focusing on variations in regression parameters and predicted PGA values. The analysis shows a strong linear correlation between regression parameters related to energy and distance, enhancing the understanding of the impact of tremors on ground motion in the USCB.

Summary: This study presents a systematic description of the coral fauna from the Agrio Formation in the Neuquén Basin of Argentina. The studied corals are capable of thriving in mixed carbonate-siliciclastic environments and show affinities with Early Cretaceous coral faunas from other regions.

Summary: This study provides the first evidence linking ocean acidification and the end-Triassic mass extinction through the analysis of carbon and calcium isotopes. The findings suggest a correlation between the decrease in calcium carbonate burial and CO2-induced ocean acidification during the Triassic-Jurassic transition. The perturbations in the carbon cycle and calcium isotopic composition are believed to be caused by the Central Atlantic Magmatic Province (CAMP) volcanic activity, contributing to the mass extinction event.

Summary: It is not enough to calculate the number of jobs in the mining industry to understand the impact of a coal phase-out on the labor market. This study estimates the number of indirect jobs in Upper Silesia, Europe's largest hard coal mining region, and categorizes them as either mining-related or mining-dependent. The authors also analyze the structure and spatial distribution of mining-related companies using data from public tenders and official administrative repositories. They find a significant concentration of companies near active mines and identify a high risk of job loss in mining-dependent companies if coal production declines. The authors argue for targeted labor market policies and use of administrative data in transition planning.

Summary: The paper describes and interprets a regurgitalite from the Middle Triassic in southern Poland, suggesting that it was produced by various potential candidates such as durophagous sharks, marine reptiles, or nautiloids. The discovery adds to the evidence of durophagous predation in the Triassic sea of Polish part of the Germanic Basin, marking the second record of a regurgitalite from the Muschelkalk of Upper Silesia.

Summary: This study focuses on a high-resolution stratigraphic, sedimentologic, petrographic, and limnogeological investigation of the Agua de la Zorra depositional system to understand its evolution through space and time and to reconstruct the development of the carbonate factory within the palaeolake. The results strongly support volcanism and tectonics as the main allogenic factors controlling the Agua de La Zorra lacustrine system evolution.

Summary: The research reveals that supporters of maintaining the coal status quo in Polish society are mainly associated with the right-wing populist ruling party Law and Justice (PiS) and the Confederation (Konfederacja); Left-wing and liberal groups are more conducive to energy transition and ecological demands. Residents of large cities, as well as those with higher education and less religious beliefs, are more willing to accept energy transition.
