| Abstract: | A total of 1 200kg of limestone samples of Middle--Upper Cambrian from Huayuan,Hunan,have been examined for conodonts. The Middle --Upper Cambrian conodont zones andagnostid zones have been erected. The correlation between these conodont zones and those ofNorth and Northeast China is expounded. Thirty-three species of 11 genera are figured. New-ly established genera are: Hunanognathus, Paibiconus. New species are: Albiconus? tricornis,Furnishina bigeminata, Hunanognathus tricuspidatus, Paibiconus proarcuatus, Westergaardo-dina brevidens, W. grandidens, W. horizontalis, W. tetragonia. |
