摘 要 ：本文简要和系统地阐述了内蒙古高原地区晚古生代植物化石及有关地层的分布，报导了西里庙植物化石(安加拉型)和大红山组植物群(华夏型)。晚古生代植物化石主要分布在哈诺敖包组(D2)，色日巴彦敖包组(D3)，宝力格组(C1-C2)，额里图组(P1)和包尔敖包组(P2)。西里庙组的植物化石有zamiopteris glossopteroides Schm.，Sphenopteris sp., S.cf.tunguscana(Schm．)Zal.，Pursongica cf．asiatica Zal.，Noeggerathiopsis sp．1，Noeggeratiopsis sp.2。大红山组植物群主要有Sphenophyllum oblongifolium，S．spedosum，S．thonii，Pecopteris arborescens，P．condolleana，P．unita，Emplectopteridium cf．alatum．Callipteridium tachingshanense， Cladophlebis? yongwalensis，Fascipteris sinensis，Sphenopteris SP.，Sphenopteridium pseudogermanicam，Cathaysiodendron nanpiaoense，Carpolithus cf．ullatus etc．

Abstract:In this paper the distribution of Late Paleozoic Strata and Fossil plants is introduced briefly and systematically new finded fossil plants are reported from Xilimiao Formation (Angara type) and Dahongshan Fonnation(Cathysian type). Addition to the now reported fossil plants the Late Paleozoic ones in Nei Mongol plateau are mainly distributed in Hanuoaobao Formation(D2), Seribayanaobao Formation(D3), Baolige Formation (C1-C2), Elitu Formation (P1), Baoeraobao Formation (P2), The fossil plants of Xilimiao Formation include Zamiopteris glossopteroides Schm., Sphenopteris sp., S. cf. tunguscana (Schm.) Zal., Pursongica cf. asiatica Zal., Noeggerathiopsis sp. 1, Noeggerathiopsis sp. 2. The flora of Dahongshan Formation is composed of Sphenophyllum oblongifolium, S. speciosum, S. thonii, Pecopteris arborescens, P. condolleana, P. unita, Emplectopteridium cf. alaturn, Callipteridium tachingshanense, Cladophlebis? yongwalensis, Fascipteris sinensis, Sphenopceris sp., Sphenopteridium pseudogermanicum, Cathaysiodendron nanpiaoense, Carpolithus cf. ullatus etc.
