This study investigates the interplay between environmental evolution and organic matter (OM) accumulation during Late Devonian, with a focus on Frasnian-Famennian (F-F) transition in Lengshuijiang section, South China. By analyzing geochemical proxies such as Total Organic Carbon (TOC), Phosphorus/Aluminum (P/Al) ratios, Chemical Index of Alteration (CIA), Co/Ni we aim to elucidate factors that controlled OM enrichment this period. Our findings suggest processes driving accumulation, including primary productivity preservation mechanisms, were closely linked significant changes. The data reveal periods high TOC coincided anoxic or euxinic conditions, driven by global sea-level changes oceanic stagnation, contributing increased stress F-F mass extinction. Additionally, fluctuations CIA values indicate alternating warm humid cooler, more arid climatic phases, which likely exacerbated disrupted marine ecosystems. research highlights interconnectedness climate, ocean chemistry, biological upheaval, offering valuable insights into drove one Earth's most profound biotic crises.

The timing and connections between global cooling, marine redox conditions, biotic turnover are underconstrained for the Late Ordovician. second most severe mass extinction occurred at end of Ordovician period, resulting in ~85% loss species two pulses. As only "Big 5" that during icehouse this interval is an important modern analog to constrain environmental feedbacks. We present a previously unexplored thallium isotope records from paleobasins record conditions document distinct rapid excursions suggesting vacillating (de)oxygenation. strong temporal link these perturbations extinctions highlights possibility dynamic oxygen fluctuations, rather than persistent, stable anoxia, played major role driving extinction. This evidence changes leading has implications deoxygenation biodiversity declines.

The colonization and expansion of plants on land is considered one the most profound ecological revolutions, yet precise timing remains controversial. Because vegetation can enhance weathering intensity affect terrigenous input to ocean, changes in terrestrial plant biomass with distinct negative Δ199Hg Δ200Hg signatures may overwrite positive Hg isotope commonly found marine sediments. By investigating secular isotopic variations Paleozoic sediments from South China peripheral paleocontinents, we highlight excursions both at Stage level starting early Silurian again Carboniferous. These geochemical were driven by increased contribution due rapid vascular plants. broadly coincide rising atmospheric oxygen concentrations global cooling. Therefore, widely distributed during Ordovician-Silurian transition (~444 million years), long before earliest reported fossil, Cooksonia (~430 years).
