| Abstract: | By using scanning electron microscope eight chitinozoan species, Conochitina chydaea Jenkins, Conochitina sp., Cyathochitina calix (Eisenaek), C. dispar Benoit &; Tau-gourdeau, C. protocalix Paris, Lagenochitina boja Bockelie, L. esthonica Eisenaek, and Rhabodochitina turgida Jenkins, are described from the limestone samples of the upper Meitan Formation at Honghuayuan, Northern Guizhou. Most of them are common species of the Arenig and Llanvirn chitinozoan assemblages in Europe, and reasonably design the age of the upper member of the Meitan Formation at Honghuaynan, as Upper Arenig to Lower Llanvirn. This is coincident with the megafossil evidence. Therefore, the fact mentioned above shows that Chitinozoa has a great significance in stratigra-phical correlation, especially in the inter-regional or inter-continental correlation. |
