A 320 MA Multi-Sphere Record of Biodiversity and Geodynamics Through Fungal Biomarkers

This study presents a high-resolution geochemical reconstruction of terrestrial biomarkers spanning the 320 Ma Carboniferous to 2026 AD Anthropocene. Utilizing a unified 800-sample matrix, I evaluated the evolutionary trajectory of wood-degrading fungal lineages—specifically the Paleancistrus-Phanerochaete transition—through the lens of Polycyclic Aromatic Hydrocarbon (PAH) molecular proxies. I introduce a multidimensional analytical framework that integrates the Combined PAH Flux Index (CPFI) and the Higher Plant Parameter (HPP) with planetary-scale drivers, including Inner Core Compositional Rayleigh Numbers (Rac), the Thermal Maturity Index (Im), and the Mathieu stability characteristic (a).
