The ma.ine losses during.the Permo-Tria.sic ma.s extinction were the worst ever experienced. a.l g.oups were ba.ly a.fected, especia.ly a.ong.t the benthos(e.g. bra.hiopods, cora.s, bryozoa.s, fora.inifers,ostra.ods).

Ma.y of the losses occur a. the beg.nning.a.d end of this interva. pa.nting.a.picture of a.two-pha.e extinction. Improved knowledg. of the extinction ha. been supported by numerous g.ochemica. studies tha. a.low diverse proposed extinction mecha.isms to be studied. a.tra.sition from oxyg.na.ed to a.oxic-euxinic conditions is seen in most sections g.oba.ly, a.thoug. the intensity a.d timing.shows reg.ona. va.ia.ility.
