山西阳泉太原组发育于晚石炭世晚期至早二叠世早期，对该组在水泉谷的一个典型剖面进行了系统的测量和描述。该地区腕足动物化石丰富，保存完好，计125种，隶属于31科48属。通过对这些腕足动物化石的详细研究，将太原组中上部早二叠世早期的腕足动物组合划分为三个组合：（3）Martinia semiplana-Choristites jigulensis组合，（2）阿莱克萨尼亚gratiodentalis-Notothyris nucleolus组合，（1）Derbyia shanxiensis-Chonetinella flemingi组合。
The Taiyuan Formation in Yangquan, Shanxi, aging from late Late Carboniferous to early Early Permian, is remarkably developed, and a typical section of this formation in Shuiquan valley has been systematically measured and described. Abundant and well-preserved brachiopod fossils of 125 species, belonging to 31 families and 48 genera, are recognized at this locality. Based on the detailed studies of these brachiopod fossils, three early Early Permian brachiopod assemblages (middle-upper part of the Taiyuan Formation) are recognized in and listed in descending order as follows: (3) Martinia semiplana-Choristites jigulensis Assemblage, (2) Alexania gratiodentalis-Notothyris nucleolus Assemblage, (1) Derbyia shanxiensis-Chonetinella flemingi Assemblage.
