Conodont Evidence for the Age of the Panxian Fauna,Guizhou, China
摘要
Abstract
Detailed conodont analysis on the Yangjuan-Chupiwa section, Xinmin, Panxian County,Guizhou Province, revealed a conodont sequence including four Anisian conodont zones, viz. Nicoraella germanica Zone, Nc. Kockeli Zone, Paragondolella bifurcata Zone and Neogondolella constricta Zone.These zones indicate that the upper Guanling Formation consists of strata from the Bithynian to the Illyrian of the Anisian. Appearance of Neogondolella constricta suggests that the Anisian/Ladinian boundary might be in the overlying Yangliujing Formation. The Panxian Fauna with well-preserved marine reptile and fish fossils is proved to belong to the lower part of the conodont Nc. Kockeli Zone in the studied area. Thus, the age of the Panxian Fauna could be the early Pelsonian of the Anisian.关键词
