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 study presents geochemical and pyrite morphological data from the Upper Permian-Lower Triassic shale succession in the Western Hubei Trough, supporting the significant role of regional tectonic activities in the hydrographic and redox evolution of the area, suggesting anoxia may not be the worldwide cause of the marine biocrisis. An extensive comparison between marine and terrestrial successions indicates that global warming in the Late Permian and global cooling in the Permian-Triassic transition may have affected the supply of freshwater to the ocean and fluctuations in seawater paleosalinity, with anomalous changes triggered by paleoclimate potentially playing a role in the biocrisis at the Permian-Triassic boundary.

Summary: This study documented the abundances of PAHs across the Permian-Triassic boundary in South China, indicating severe perturbations to terrestrial ecosystems before the marine crisis. The peak of PAHs in the EPME period suggests simultaneity of the most severe phases of terrestrial and marine crises. The study also validates the utility of certain hydrocarbon compounds as proxies for terrestrial wildfires in deep-time marine successions.

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: This study investigates the patterns of latitudinal diversity gradients (LDGs) from the Carboniferous icehouse to the Triassic greenhouse climates using marine invertebrate fossils. The results suggest that LDG peaks are influenced by multiple factors rather than solely alternating icehouse and greenhouse climates, with icehouse climates generally restricting diversity at high latitudes. The diversity peaks shifted northward during the late Carboniferous and early Permian, likely due to plate drift and increased habitat area. Changes in LDG steepness were most pronounced at low latitudes and during biotic crises and recovery, while transitions from icehouse to greenhouse climates created more deviation at high latitudes.

Summary: This study focused on the morphological changes and ontogenetic series of important Griesbachian-Dienerian conodonts based on well-preserved specimens from northwestern Pakistan. By reconstructing their phylogenetic relationships and analyzing morphometric data, the study identified complex evolutionary trends and heterochronic patterns in platform growth. The reduction of platform in late Griesbachian species was attributed to progenesis and neoteny, while the Dienerian segminate conodonts exhibited postdisplacement of the flange. Additionally, the study suggested that the Dienerian Neospathodus lineage represented a paedomorphosis of the flange, while the Sw. kummeli-Eu. costatus lineage may have undergone peramorphosis of the platform through acceleration.

Summary: The Permian-Triassic mass extinction caused a severe decline in biodiversity, and information on soft-bodied animals comes from trace fossils. Analysis of trace fossils revealed that infaunal ecologic structure was established in the early Smithian period. The decoupling of diversity between deposit feeders and suspension feeders in carbonate ramp-platform settings may have delayed the recovery of nonmotile, suspension-feeding epifauna in the Early Triassic.

Summary: This study investigates the Tonian Longfengshan biota in Hebei Province, North China using various microscopic and geochemical analysis techniques. The results show that the fossil specimens are preserved as carbonaceous patches and have high calcium content. Iron-rich clay minerals are also associated with the fossils. The integration of data suggests that the fossil-bearing shale was deposited in the subtidal zone below storm wave base, and the degradation process of the fossils may have been inhibited by iron-replete but sulfate-depleted porewater.

Summary: The history of Earth's biodiversity has been marked by periodic mass extinctions, with major declines in species richness. However, the accompanying ecological collapse has seldom been quantitatively evaluated. The Permian-Triassic mass extinction, as the largest known extinction event, permanently changed marine ecosystems and facilitated the transition from the Paleozoic to Mesozoic faunas. This extinction event provides insight into the relationship between species richness and ecological dynamics during severe extinctions, but the ecological collapse during this event has not been thoroughly examined.

Summary: A precise global timescale for the Lower Triassic Series is essential for understanding the sequence of events following the mass extinction. The recognition of an Induan-Olenekian boundary (IOB) is crucial for establishing a high-resolution chronostratigraphic framework for this interval. Recent research on conodont biostratigraphy has led to a refined definition of the IOB, with proposed markers for the boundary. Rating: 8

Summary: Using Bayesian analyses, this study finds that brachiopods and bivalves displayed similar large-scale trends of diversification before the Jurassic period. The extinction of major brachiopod clades during the Permian-Triassic mass extinction set the stage for the switch from brachiopods to bivalves, with high ocean temperatures post-extinction further facilitating the displacement of brachiopods by bivalves.

Summary: Through sediment records from Lake Nanyi in the lower Yangtze, we found that anthropogenic fire activity played a dominant role in the region, and the temporal pattern of fire activity was asynchronous from east to west. Archaeological evidence suggests an inverse relationship between agricultural and population levels and fire intensity during the mid-Holocene, with fire intensity being influenced by the diversity of landscape types associated with pre-historic subsistence patterns. Overall, changes in regional water-level delayed the transition from hunting-gathering to agriculture in the lower Yangtze region.

Summary: This paper argues that sessile barnacles are an excellent proxy for palaeoenvironmental reconstructions. The shells of barnacles consist of diagenetically stable low-magnesium calcite and record short-term variations. Analyses of several Western Mediterranean barnacle-rich deposits demonstrate the utility of barnacles as proxies for water depth, distance from the coastline, and hydrodynamic conditions. Moreover, the stable isotope ratios of barnacle shells can provide detailed palaeoenvironmental information.

Summary: The Late Ordovician mass extinction occurred during an ice age, with maximum ice coverage and a substantial drop in global sea level. This led to the exposure or shallowing of shallow tropical shelf environments. The study suggests that the burial rate of nutrient phosphorus (P) on shelves was minimal during this glacial period, leading to excess bioavailable P entering the open ocean and stimulating phytoplankton production, which in turn lowered oxygen concentrations.
