【Abstract in Chinese】 云南省昭通市东北郊箐门出露了一条比较完整的泥盆系浅海相地层剖面,下、中、上三个统均有出露,浅海底栖生物化石丰富,研究基础也相对较好,是研究滇东北地区泥盆纪地层的一条理想剖面。由于地层剖面比较长,沉积厚度比较大,此前我们已经描述了早泥盆世和中泥盆世早期的四射珊瑚,本文继续描述该剖面的中泥盆世晚期的地层及其四射珊瑚,讨论它们的地层划分、珊瑚群对比与古生物地理。至于晚泥盆世的珊瑚,由于篇幅的关系,我们拟另文继续描述。

【Abstract】 A relatively complete and extended Devonian shallow marine sequence crops out in the vicinity of Qingmen village in the northeastern suburb of Zhaotong,Yunnan Province.Lower to Upper Devonian strata are all exposed,with abundant shallow water benthic fossils.It is an ideal area for Devonian studies in the northeastern Yunnan Province.The stratigraphic succession has been well established,which is very thick.Nevertheless,benthic fossils have not been described.The present paper is the second of the series of rugose coral studies,dealing with late Middle Devonian(Givetian)strata and corals,with discussions on stratigraphic divisions and correlations,as well as the coral paleobiogeographical relationship.Six genera and species have been described,with a new genus and species named.They are Endophyllum panxiense Liao,Ma and Sun,Sinospongophyllum sp.,Parasociophyllum isactis(Frech),Argutastrea endecus(Kong),Temnophyllum poshiense Wang and Dianqianophyllum bianqingense gen.et sp.nov.
