【摘要】 太原东山本溪、太原组地层中腕足动物化石相当丰富,共计56属148种分属于8目28科。不同组的地层中腕足动物群内容差异甚大,具有明显的阶段性。本文据此建立了4个腕足动物化石组合带,并阐述了腕足动物的兴衰递变规律。通过对国内外同期腕足动物群的对比,认为腕足动物组合对地层划分与对比具有重要意义。更多还原

【Abstract】 Fossils of brachiopods from Penchi and Taiyuan Formations in Eastern Hill of Taiyuan,Shanxi,are abundant.Altogether,56 genera and 148 species,belonging to 28 families and 8 orders,can be recognized.However,they are quite different in features and indicate clearly that they were formed in different periods. Based on this the paper divides them into 4 zones,and describes evolution of brachiopods.The authors consider that the assemblages of brachiopods are of great importance to division and correlation of ground strata from this area with those from other parts of the world in the same age.更多还原
