摘要
In this paper the coral fossils in the Ordovician reefs in the southern edge of the Ordos Basin are described.They include 14 species referred to 8 tabulate genera as Lichenaria,Amsassia,Rhabdotetradium,Syringoporella,Catenipora,Yao-xianopora,Plasmoporella,and Parastelliporella and 4 species referred to 3 rugosan genera as Dinophyllum,Ningnanophyllum,and Favistella.This study reveals that Lichenaria,Amsassia,Syringoporella were the main reef builders in the Middle Ordovician reef at Haoshihe,Qianxian County,Shaanxi Province.Catenipora,Plasmoporella,Favistella,occur in the breccia of the reef-front facies of the Upper Ordovician reef at Tiewadian,Chunhua County,Shaanxi Province.Yaoxianopora is a secondary reef-builder in the Middle Ordovician reef at Taoqupo,Yaoxian County,Shaanxi Province.
