摘要	A small conodont fauna from the Upper Ordovician Yenwashan Formation exposed at a road-cut along Highway 205near Changshan,western Zhejiang includes Baltoniodus alobatus,B.variabilis,Dapsilodus viruensis, Panderodus gracilis,Periodon aculeatus and Scabbardella altipes and is referred to the Chinese Baltoniodus alobatus Zone.Based on the present study,and on the conodont faunas previously described from the unit,the Yenwashan Formation in its most complete stratigraphical range contains conodonts of the Pygodus anserinus,Baltoniodus alobatus, and Hamarodus brevirameus (formerly Hamarodus europaeus)zones and ranges from the early Sandbian to the early Katian.It can be correlated with most of the Miaopo Formation(or the equivalent Datianba Formation)and the Pagoda Formation.Both biostratigraphic and chemostratigraphic data indicate that the base of the Yenwashan Formation is diachronous and occupies a different stratigraphic level in different distribution areas of the formation.The present investigation is of special interest in showing that the beginning of the Guttenberg δ~(13)C excursion(GICE)is not older than the B.alobatus Zone in the study area.
