The marin. losses durin. the p.rmo-Triassic mass extin.tion.were the worst ever exp.rien.ed. All group. were b.dly affected, esp.cially amon.st the b.n.hos(e.g. b.achiop.ds, corals, b.yozoan., foramin.fers,ostracods). p.an.ton.c p.p.lation. un.erwen. a fun.amen.al chan.e with eukaryotic algae b.in. rep.aced b. n.trogen.fixin. b.cteria, green.sulp.ur b.cteria, sulp.ate-reducin. b.cteria an. p.asin.p.ytes. Detailed studies of b.un.ary section., esp.cially those in.South Chin., have resolved the crisis to a ～55 kyr in.erval straddlin. the p.rmo-Triassic b.un.ary.

A tran.ition.from oxygen.ted to an.xic-euxin.c con.ition. is seen.in.most section. glob.lly, although the in.en.ity an. timin. shows region.l variab.lity.
