| Abstract: | A detailed study and systematic bed-by-bed collection of the lower Ordovician chitinozoans from the Chenjiahe section in the Yichang area,Hubei,China,suggest that two chitinozoan biozones,the Lagenochitina destombesi Biozone and Euconochitina symmetrica Biozone,can be recognized in the Fenghsiang and Hunghuayuan Formations. The assemblage characteristics of the chitinozoans zones and the correlation with graptolite and conodont biozones and the equivalent chitinozoan biozones in other areas of the world are... |
