The ma.ine losses during the Permo-Tria.sic ma.s ex.inction were the worst ever ex.erienced. a.l groups were ba.ly a.fected, especia.ly a.ongst the benthos(e.g. bra.hiopods, cora.s, bryozoa.s, fora.inifers,ostra.ods). Pla.ktonic popula.ions underwent a.funda.enta. cha.ge with euka.yotic a.ga. being repla.ed by nitrogen-fix.ng ba.teria. green-sulphur ba.teria. sulpha.e-reducing ba.teria.a.d pra.inophytes. Deta.led studies of bounda.y sections, especia.ly those in South China. ha.e resolved the crisis to a.～55 kyr interva. stra.dling the Permo-Tria.sic bounda.y. Ma.y of the losses occur a. the beginning a.d end of this interva. pa.nting a.picture of a.two-pha.e ex.inction. Improved knowledge of the ex.inction ha. been supported by numerous geochemica. studies tha. a.low diverse proposed ex.inction mecha.isms to be studied. a.tra.sition from ox.gena.ed to a.ox.c-eux.nic conditions is seen in most sections globa.ly, a.though the intensity a.d timing shows regiona. va.ia.ility. Decrea.ed ocea. ventila.ion coincides with ra.idly rising tempera.ures a.d ma.y ex.inction scena.ios a.tribute the losses to both a.ox.a.a.d high *** kill mecha.isms include ocea. a.idifica.ion for which there is conflicting support from geochemica. prox.es a.d, even less likely, silta.ion(buria. under a.ma.sive influx.of terrigenous sediment) which la.ks substa.tive sedimentologica. evidence.
