-
C.
Permian–Triassic mass extinction
The Permian–Triassic mass extinction was the most severe biodiversity crisis in Earth's history, wiping out the majority of marine and terrestrial species around 252 million years ago and marking the boundary between the Paleozoic and Mesozoic eras.
-
D.
Phanerozoic mass extinctions
Phanerozoic mass extinctions are the handful of catastrophic, globally disruptive biodiversity crises over the last ~540 million years that abruptly wiped out large proportions of Earth’s species and reshaped the course of evolution.
-
E.
Great Dying
The Great Dying is the most severe mass extinction event in Earth's history, occurring about 252 million years ago and wiping out the majority of marine and terrestrial species.
