Summary: Metoposaurids are large-bodied temnospondyls found in non-marine Late Triassic deposits across northern Pangea. The taxonomy of some species is still unclear, leading to the establishment of a new genus. The phylogeny of the Metoposauridae is labile, posing challenges to understanding their evolutionary history.

Summary: The study validates pigmentary hematite as a proxy indicator for the Late Triassic environment through analyzing a red bed sequence in Arizona. The results show the evolving pattern of the Late Triassic monsoon, a long-term rise in aridity starting around 215 Ma, and increased oscillatory climate change at around 213 Ma. These changes are attributed to the drift of the Colorado Plateau northward as part of Laurentia and fluctuating CO2 levels.

Summary: In the Precambrian, reverse weathering played a key role in the carbon cycle, but marine silicifiers reduced its importance in the Phanerozoic. This study shows that an increase in reverse weathering rates led to a decline in seawater Li isotopes during the Late Permian and Early Triassic, explaining the failure of chemical weathering to decrease atmospheric CO2 levels during this period.

Summary: The paper discusses the abundance, diversity, and extinction of non-marine algae in the Permian and Triassic periods, focusing on the aftermath of the end-Permian extinction interval. It also provides insights into the global biotic crises within the Permian-Triassic interval and the fossil records of non-marine algae in Gondwana. Finally, the review highlights the scarcity of quantitative fossil evidence for non-marine algae during these critical periods in evolutionary history.

Summary: The study describes a Permian paleoassemblage from the Balearic Islands, consisting of small captorhinomorph eureptiles, parareptiles, and two different taxa of moradisaurines, including a new species Balearosaurus bombardensis gen. et sp. nov. The findings suggest that the Variscan mountains were not a significant barrier for the dispersion of moradisaurines, with their distribution area encompassing both sides of the mountains in the arid belt of palaeoequatorial Pangaea.

Summary: This study comprehensively revised the late Cisuralian central Pangaea and found a significant increase in drought-tolerant forms during the Artinskian period, possibly due to a global climatic event caused by volcanic eruptions that led to the final melting of the Gondwanan ice sheets.

Summary: This study presents a high-resolution record of atmospheric CO2 and marine phytoplankton community structure during the Permian-Triassic mass extinction. The findings suggest that the first extinction was associated with a minimum CO2 concentration, followed by a rapid rise to a prolonged high CO2 interval. Cyanobacteria played an increasingly dominant role in marine export production between the two extinction events.

Summary: This study examines palynological successions from the late Permian to the Early Triassic in southwestern China and identifies four distinct palynofloral assemblages. The results suggest that the Permian-Triassic mass extinction had a significant impact on terrestrial vegetation in southwestern China. The findings support the hypothesis that the extinction process of terrestrial vegetation was a two-staged and longer-duration event.

Summary: This paper presents a taxonomic study on the diverse chondrichthyan fauna from the Luolou Formation in South China. The study recognizes nine different taxa of sharks, indicating a high diversity and evenness in the shark palaeocommunity. The diverse morphologies of the sharks suggest adaptation to various feeding strategies.

Summary: This study provides a detailed interpretation of the Permian ecosystems in Mallorca and improves the characterization of the Permian-Triassic tectonosedimentary cycle in the Balearic Islands. The findings contribute to the understanding of the evolution of western peri-Tethys ecosystems.

Summary: This study analyzed the shell-size changes in bivalve fossils from South China during the end-Permian mass extinction and Early-Middle Triassic recovery. The results showed a significant reduction in shell size immediately after the extinction event, followed by a quick rebound and growth in the late Griesbachian. The variations in bivalve size were mainly influenced by factors such as competition, predation, and climatic and oxygen changes.

Summary: Permian chert successions were geographically extensive, but there was a multi-million-year chert gap in the Early Triassic. The weakening of chert production was related to water column deoxygenation, increased carbonate and siliciclastic components, and decreased primary productivity. The primary cause of Early Triassic chert demise is the loss of siliceous biomass during the end-Permian crisis.

Summary: The discovery of a new species of Chroniosuchians, Laosuchus, with specific cranial features classified under the Chroniosuchidae family, reinforces the hypothesis of a migration route from North China to Laos. This study confirms the divergence of Chroniosuchidae and Bystrowianidae and expands our understanding of the evolutionary history of these reptiliomorphs in the Triassic period.

Summary: The study of mafic dikes in the Gulinjing-Nanxi area indicates that they are likely linked to Paleo-Pacific subduction rather than being part of the Emeishan mantle plume. Zircon ages, elemental compositions, and isotopic signatures differentiate these dikes from the nearby Emeishan flood basalts, supporting a connection to a different subduction zone in the region.

Summary: This study reevaluates a dinosaur specimen from southern Brazil, known as the 'Big Saturnalia', and finds it to have herrerasaurid affinities, making it one of the largest herrerasaurid specimens from the Candelaria Sequence. This specimen, with cranial and postcranial elements, offers new insights into the anatomy, evolution, and distribution of Herrerasauridae. Its large size further supports herrerasaurids as top-tier predators during the early stages of dinosaur evolution in southwestern Pangaea.

Summary: This article describes a Triassic cynodont species called Prozostrodon brasiliensis, which is important in studying the emergence of mammalian characters. The analysis of a well-preserved skull of Pr. brasiliensis reveals the existence of a new South American cynodont clade called Prozostrodontidae, which is on the stem lineage of mammals.
