【摘要】 系统描述了采自藏北申扎地区下泥盆统达尔东组的部分珊瑚类化石。其中,皱纹珊瑚7属5种(含1新种Hunanaxoniaxizangensissp.nov.)及2个未定种;床板珊瑚形珊瑚4属4种,含2个新种(Pachycanaliculasparculasp.nov.,Parahelioliteszakangensissp.nov.)。这些珊瑚化石的发现将有助于进一步了解本区早泥盆世珊瑚动物群的共生组合、演化以及珊瑚的古生物地理区系。更多还原

【Abstract】 Some coral fossils newly collected from Lower Devonian Daerdong Formation of Xainza, Tibet have been systematically described. There are 7 species of rugosa including one new species, 4 species of tabulatomorphic corals including 2 new species. The three new species are Hunanaxonia xizangensis sp. nov., Pachycanalicula sparcula sp. nov. and Paraheliolites zakangensis sp. nov. The discovery of these corals in this area is beneficial for more understanding the symbiotic assemblage, evolution of the corals and their biogeography in Early Devonian.更多还原
