滇西保山、施甸地区(澜沧江与怒江之间)属欧亚大陆边缘地带,是研究古地理区划、板块构造及地层对比的重要地区之一。该区早石炭世地层发育较好,分布广泛,化石丰富,主要是一套浅海相碳酸盐岩沉积。自下而上分为香山组和铺门前组。香山组产有丰富而保存完好的珊瑚化石。笔者(1981, 1993)曾两次赴该区研究泥盆、石炭纪珊瑚及地层。本文仅报道有关 Pseudouralinia 珊瑚动物群的部分研究成果,新建了一个 Pseudouralinia-Humboldtia rossica-Cyathoclisia taber-
Baoshan and western Yunnan provinces (between Lancang River and Nujiang) belong to the margin of Eurasia, and are one of the most important areas for studying paleogeography, plate tectonics and stratigraphic correlation. The Early Carboniferous strata in this area are well developed, widely distributed and rich in fossils, mainly consisting of a set of shallow marine carbonate deposits. Bottom-up divided into Xiangshan group and shop front group. Fragrant Hill Group has rich and well-preserved coral fossils. The author (1981, 1993) went to the area twice to study Devonian, Carboniferous corals and strata. In this paper, only part of the research on the Pseudouralinia coral fauna was reported, and a new Pseudouralinia-Humboldtia rossica-Cyathoclisia taber-
