Phanerozoic Biodiversity Mass Extinctions
Phanerozoic Biodiversity Mass Extinctions is a scholarly work, published in 2006 in ''Annual Review of Earth and Planetary Sciences''. The main subjects of the publication include carbon cycle, geology, Ordovician, geochronology, paleontology, extinction, extinction event, ecology, biodiversity, paleoclimatology, and Phanerozoic. Recent analyses of Sepkoski's genus-level compendium show that only three events form a statistically separate class of high extinction intensities when only post-Early Ordovician intervals are considered, but geologists have called numerous events mass extinctions.
