Marine extinction intensity during Phanerozoic % Millions of years ago (H) K–Pg Tr–J P–Tr Cap Late D O–S An extinction event (also known as a mass extinction

Cretaceous–Paleogene (K–Pg) extinction event, formerly known as the Cretaceous-Tertiary (K–T) extinction event, was the mass extinction of three-quarters of

species. It is also the greatest known mass extinction of insects. It is the greatest of the "Big Five" mass extinctions of the Phanerozoic. There is evidence

The Holocene extinction, also referred to as the Anthropocene extinction or the sixth mass extinction, is an ongoing extinction event caused exclusively

as the end-Ordovician mass extinction or the Ordovician–Silurian extinction, is the first of the "big five" major mass extinction events in Earth's history

biodiversity as one of the "Big 5" mass extinction events. After the discovery that the Cretaceous-Palaeogene extinction event was caused by an impact event

end-Guadalupian extinction event, the Guadalupian-Lopingian boundary mass extinction, the pre-Lopingian crisis, or the Middle Permian extinction) was a major mass extinction

change for hundreds of millions of years. Mass extinctions are relatively rare events; however, isolated extinctions of species and clades are quite common
