Abstract. The end-Permian mass extinction horizon is marked by an abrupt shift in style of carbonate sedimentation and a negative excursion in the carbon isotope ( δ13 C) composition of carbonate minerals. Several extinction scenarios consistent with these observations have been put forward. Secular variation in the calcium isotope ( δ44/40 ...The main phase of the end-Permian extinction occurs at. the basal ‘boundary ash clay’ layer of Bed 25 in the Meishan. section (Jin et al., 2000) and is distinct from the.In addition to their devastating effects on global biodiversity, mass extinctions have had a long-term influence on the history of life by eliminating dominant lineages that suppressed ecological change.

It is the most severe mass extinction of all life—“the mother of all extinctions”—and promoted the evolution of modern ecosystems (e.g., Raup and Sepkoski 1982 ; Erwin 1993 , 2006 ).All of the major animal groups of the Ordovician oceans survived, including trilobites , brachiopods , corals , crinoids and graptolites, but each lost important members.
