E_4_27 — Chicxulub Impact and the K-Pg Mass Extinction

E_5_03 — The End-Triassic Mass Extinction
The End-Triassic mass extinction (c. 201.564 ± 0.015 million years ago) was one of the "Big Five" mass extinctions in Earth's history, eliminating approximately 76% of all species and ~50% of genera, clearing the ecologi
E_5_07 — Post-Extinction Recovery Patterns: Adaptive Radiation After Mass Dying
Mass extinctions are not merely episodes of destruction — they fundamentally reshape the trajectory of life through the recovery dynamics that follow. Post-extinction recovery is typically slow (5–10 million years for fu
