【摘要】 <正>一、前言我国内蒙古自治区海相二叠系分布相当广泛,动物化石丰富。研究最早的地点是乌兰察布盟北部的哲斯红格尔。美国自然博物馆中亚考察团勃克 (C．P．Berker)、毛里士(P．K．Morris)于1922年首次在该地发现化石,在1923,1925 年又先后两次做了调查,并采集了大量腕足类和部分软体、珊瑚等化石,把产化石的地层命名为哲斯组(Jisu Honguer formation)发表在《蒙古地质》(Geology of Mongo- lia)一书中。勃克等所采集的化石标本,1927年由赵亚曾研究发表了其中若干长身贝类。 1931年,葛利普(A．W．Grabau)又做了全面描述,发表于他的名著《蒙古的二叠纪》 (The Permian of Mongolia)一书中。更多还原

【Abstract】 In Zhesi (哲斯,i.e.,Jisu Houguer,in Berker and Morris,1927) district of Nei Mongol (内蒙古) Zizhiqu,the marine sediments of the Lower Permian, containing plentiful fauna,are well developed.On the subject of studying the stratigraphy and fauna,a professional group has been inaugureted by Tianjin Institute of Geology and Mineral Resources and the Regional Surveying Team, Geological Bureau of Nei Mongol Zizhiqu,and the geological survey was carried out in 1976 at Zhesi Hill (哲斯敖包) and Baotege (包特格) areas of Mandula (满都拉) Commune in Darhan Muminggan Lianheqi (达尔罕茂明安联 合旗,Damuqi is the abbreviation.),Ulanqab (乌兰察布) District.The sections at Zhesi,Yihewusu (义和乌苏),Bulege (布勒格),Hadanhoubu (哈丹厚布), Baotege and Manaolete (马脑勒特) were measured and over 3000 specimens of various kinds of fossils were systematically collected.There are indications that the brachiopods prosperously developed in Zhesi District in Early Per- mian and the fusulinids,corals,bryozoans and molluscs were also abundant, which form the subject of the present account.The fossils described and illustrated in this paper comprise 93 genera,204 species,subspecies and uni- dentified species,in which 7 genera,94 species and subspecies are new forms.更多还原
