Seventy-two samples from the Silurian Luoreping Formation and Member 1 of the Shamao Formation were analyzed for microfossils.Thirty-six of them,which are grey-greenish mudstone or siltstone samples,yielded abundant well-preserved early Silurian chitinozoans.Two chitinozoan biozones,which in ascending order are Conochitina rossica and Conochitina malleus biozones,are recognized.Each chitinozoan biozone is diverse and includes both new and previously described species.They can be correlated with chitinozoan biozones from contemporaneous strata of the Latvia and Estonia.Based on the relationships among Silurain chitinozoan,graptolite,and conodont biozones in the Yichang area,we conclude that the chronostratigraphic range of the Luoreping Formation in the Yichang area roughly correlated with the Stimulograptus sedgwickii graptolite biozone.
