Abstract:
Abundant rugose corals including 33 genera and 77 species were collected in 1988 from the fusulinid Montiparus zone to Brevaxina dyhrenfurthi subzone in South Guizhou. Among these species, 10 species are here described as new. Based on stratigraphical distribution of these rugose corals, 4 assemblage zones can be recognized as follows in ascending order: 1) Antheria Pseudotimania Assemblage 2) Nephelophyllum Eokepingophyllum Assemblage 3) Parawentzellophyllum Kepingophyllum Assemblage 4) Anfractophyllum Assemblage 1) and 2) assemblages are dominated by Cyathopsidae taxa Pseudozaphrentoides, Botherophyllum and Caninophyllum as well as primitive representatives of Kepingophyllidae. It is noteworthy that some pioneers of Waagenophyllidae and Wentzellophyllidae have occurred in the Assemblage 2). Assemblage 3) is represented by typical elements of Kepingophyllidae, including Kepingophyllum, Parawen tzellophyllum , and Diversiphyllum. Taxa belonging to Cyathopsidae and those primitive representatives of Kepingophyllidae are significanlly decreased in number in this assemblage. Assemblage 4) is dominated by such advanced representatives of Kepingophyllidae as Anfractophyllum and Szechuanophyllum.
