Late Devonian extinction. Comparison of the three episodes of extinction in the Late Devonian (Late D) to other mass extinction events in Earth's history. Plotted is the extinction intensity, calculated from marine genera. The Late Devonian extinction was one of five major extinction events in the history of the Earth's biota. A major extinction, the Kellwasser event, occurred at the boundary that marks the beginning of the last phase of the Devonian period, the Famennian faunal stage (the FrasnianâFamennian boundary), about 375â360 million years ago.
