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.

Body size greatly affects how organisms interact with their environments. However, the macroevolutionary patterns of body across many major metazoan clades and constraining mechanisms remain elusive. A new high-resolution dataset covering 2435 species from 1091 genera Cambrian Ordovician trilobites reveals that evolution changes episodically, three marked reductions in size. Such a pattern rules out persistent Cope’s rule dynamic. Rather, we find strong temporal link between fluctuations marine redox, supporting hypothesis oxygen levels exerted primary control on tempo mode trilobite evolution. These further imply dominant role for early animal
