Summary: The Aquidauana Formation in Brazil's Late Paleozoic Ice Age presents a unique sedimentary record with a rich ichnofossil assemblage dominated by small arthropods, reflecting low functional morphology richness and environmental stress related to glacial environments. The presence of Warvichnium and Monomorphichnus distinguishes it from other Gondwanic glacial deposits, suggesting a relationship with freshwater influence and invertebrate colonization followed by subaerial exposure.

Summary: In this study, the researchers describe Balhuticaris voltae, a bivalved arthropod from the 506-million-year-old Burgess Shale. This species has an extremely elongated body with ca. 110 pairs of homonomous biramous limbs, making it one of the largest Cambrian arthropods known. Balhuticaris has an unusual carapace resembling an arch and is likely an active swimmer due to its powerful paddle-shaped exopods and flexible body. The discovery of Balhuticaris adds to the ecological and functional diversity of bivalved arthropods and suggests that gigantism occurred in more arthropod groups than previously recognized.

Summary: Compensatory wetland restoration is a critical component of comprehensive, ecosystem-level oil spill response strategies. Post-restoration monitoring and assessments often overlook faunal assemblages and trophic dynamics, which are important for rehabilitating food webs. Different approaches to wetland restoration can influence faunal recovery and trophic interactions. This study compared plant communities, terrestrial arthropod assemblages, and trophic relationships in different types of restored emergent marshes and reference areas. The results showed differences in plant community composition, species composition of herbivores, and trophic relationships between restored and reference areas, highlighting the importance of geomorphological heterogeneity and plant diversity in supporting diverse species and functions.

Summary: The Cimmerian continent is made up of blocks that were attached to Gondwana in different time periods, developing glacial sediments during the Late Paleozoic Ice Age. These blocks present a combination of warm and cool water sediments, lacking upper Carboniferous sediments and showing similarities to Australia and India/Pakistan. Additionally, they are characterized by the absence of upper Carboniferous sediments, making them significantly different from South China and other Tethyan regions.

Summary: The study revises arthropod trackways in the Turonian Nimar Sandstone formation in India, merging several ichnogenera into one based on morphological similarities. The differences in morphology are attributed to variations in behavior and environment, highlighting the importance of these factors in trace fossil preservation.

Summary: Systematic literature reviews are commonly used in biodiversity conservation to identify knowledge gaps and strategies for improvement. However, these reviews are often not standardized and may have varying methods and data sources. A comparison of two systematic reviews on terrestrial arthropod conservation translocations revealed similar findings regarding geographic and taxonomic biases, but different conclusions about factors influencing success due to varying data sources. Improved communication and data sharing among researchers and practitioners is necessary to ensure comprehensive and accurate systematic reviews in conservation.

Summary: By studying the Fengcheng Formation in northwest China, we have confirmed that it records the Carboniferous-Permian boundary. Through global carbon isotope data, we found the similarity of negative carbon isotope excursions in terrestrial and marine profiles, supporting their global synchrony and potential use for delimiting the Carboniferous-Permian boundary in terrestrial sections. This study contributes to understanding the Carboniferous-Permian global carbon cycle, high-latitude glaciation, eustatic fluctuations, global volcanism, and their potential relationships.

Summary: The study in South China during the early Carboniferous period found that terrestrial organic matter played a significant role in paleo-environmental changes and organic matter deposition in black shales. Key indicators such as sedimentary delta N-15 values and the organic matter compositions highlighted the contribution of terrestrial OM to marine sediments. In summary, the transportation of large quantities of TOM from land to ocean may have led to a significant decrease in atmospheric pCO(2) levels and subsequent cooling climate.

Summary: The Badstub Formation in Notsch, Austria, contains rocks with preserved sedimentary features. Analysis revealed syn-metamorphic foliation, mineralized faults, veins, and corona textures. Thermodynamic modeling and geothermometry indicated metamorphic conditions of 260-310 degrees C and 0.25-0.50 GPa.

Summary: After the revision of collections in the Ostrava Museum, seven species of medullosalean prepollen organs were identified. These organs, originating from the Carboniferous Karvina Formation, have elliptical prepollen grains with a single suture and two longitudinal grooves. Some of them are assigned to the Monoletes ovatus species and associated with specific foliage.

Summary: Large-winged blattoids of the Middle to Late Pennsylvanian exhibit diversification, colonization, and decline. The families Necymylacridae and Gyroblattidae, as well as the mylacrid genus Opsiomylacris, were the largest blattoids before the Cenozoic era. These giant insects spread during the Bashkirian-Moscovian transition, diversified during late Moscovian and Kasimovian times, and disappeared in the middle Gzhelian. Gyroblattids followed meso- to xerophilous plants and colonized areas with a broader range of soil conditions.

Summary: The terrestrial planets are believed to have formed by violent collisions of tens of lunar- to Mars-size protoplanets within 200 million years after the dispersal of the protoplanetary gas disk. The rapid formation and radial migration of the solar system giant planets may have influenced the formation of the terrestrial planets.

Summary: New invertebrate trace fossils from the Lower Jurassic Moenave Formation at the St. George Dinosaur Discovery Site at Johnson Farm have been discovered, possibly left by crayfish or similar animals. This trace has been named Siskemia eurypyge and represents the first recorded locomotion trace of crayfish or similar animals.
