Timeline of extinctions in the Holocene

This timeline of extinctions is an historical account of species that have become extinct during the time that modern humans have occupied the Earth.

The following is a selective list made by sampling a very small proportion, mostly mammals, of some of the well-known extinct species in recent history. For a more elaborate list see Lists of extinct animals. The vast majority of extinctions, though, are thought to be undocumented. According to the species-area theory and based on upper-bound estimation, the present rate of extinction may be up to 140,000 species per year.[1] See Holocene extinction for more information.

The Holocene is considered to have started at the Holocene glacial retreat main event at 9700 BCE. Species had also become extinct due to human activity before that date.
