Mass extinction events represent some of the most significant disruptions in Earth history. Conventional explanations include volcanic activity, impact events, climate instability, ocean chemistry change, atmospheric stress, ecological collapse, and interactions among multiple environmental drivers.
This paper does not seek to resolve extinction causation. Instead, it treats extinction intervals as large-scale environmental expressions that can be compared against geological structure, basin reorganization, and regional-to-global transition patterns.
The analysis focuses on observable disruption signatures: abrupt sedimentary changes, oceanic stress, volcanic markers, isotopic excursions, basin transitions, and broader environmental instability. These features are treated as measurable indicators of system-level change.
Under the Ontomics frame, extinction-associated disruption is not introduced as a conclusion, but as a comparison layer. The question is whether major biological and environmental transitions show spatial or geological coherence when placed next to the structural sequence already being built.
This paper creates a careful bridge between geology and consequence. It keeps the claim bounded while preparing the series for pressure redistribution, global alignment, trench depth, and later planetary-scale synthesis.
This is Paper 6 in the sequence. It introduces environmental disruption cautiously, linking structural geology to Earth-system transition without asserting direct causation.
