| 摘 要： | 早石炭世晚期至晚石炭世早期，太子河流域发育了一套红层沉积，泥岩中含有丰富的腕足动物化石，共计２１属３９种。系统分析了腕足动物群性质；结合围岩和地球化学特征等，识别出ＬｉｎｏｐｒｏｄｕｃｔｕｓＯｖａｔｉａ群落，它生活在与广海相连的浅水海湾低潮线附近地带；对同期腕足动物群进行了比较和讨论，提出当时研究区属于天山—辽吉腕足动物生物地理分区的观点。

| Abstract: | Late Early Carboniferous to early Late Carboniferous red beds are well developed in the Taizi River region,eastern Liaoning Abundant brachiopod fossils,including 21 genera and 39 species,have been collected form two reddish mudstone beds The writers have analysed systematically the characters of the brachiopod fauna On the basis of the statistical analysis of the fauna and sedimentary and geochemical features,the Linoproductus Ovatia community,living near the low tide line of a gulf connecting with a normal sea,have been recognized The correlation between the brachiopod fauna in the study area and those in other parts of the world suggests that the fauna can be compared with that in Tianshan,Xinjiang So the authors propose that the study area belongs to the Tianshan Liaoji brachiopod biogeographic province |
