“Classification System for Mass Extinction Causation: Ultimate vs Proximate Factors”

https://pubmed.ncbi.nlm.nih.gov/38116094

This abstract proposes a classification system for mass extinction causation, distinguishing between ultimate causes, such as bolide impacts or large igneous province eruptions, and proximate causes, like carbon-release or carbon-burial processes, and provides examples of these causes in specific mass extinctions.
