Time and again, over hundreds of millions of years, environmental disturbances have
caused mass extinctions of animals ranging from reptiles to corals. The anthropogenic loss …

The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the
occurrence of a very large bolide impact and flood basalt volcanism near the boundary …

The end-Triassic mass extinction overlapped with the eruption of the Central Atlantic

The mass extinction at the Cretaceous–Paleogene boundary,∼ 66 Ma, is thought to be
