摘要
两极分布的凉水型分子是古地理一级区划的重要标志之一。根据兴蒙遣山带中二叠世哲斯期的10个腕足动物属(族)的地理分布的特征分析,Yakovlevia等腕足动物的地理分布具有两极分布的特点。是典型的凉水型的腕足动物,并具有亲北极生物的特征,其古生物地理区划应该属于北方大区。
The cold-water-type brachiopod is one of the most important indicators in classification of the realm of paleobiogeographic habitation. According to the paleogeographic distribution, some Brachiopod genus, such as Yakovlevia, appear a feature of bipolar distribution, which arecold-water-type brachiopod. Therefore, it is thought that the paleobiogeographic realm of Zhesi Stage brachiopod fauna should be in the Boreal Realm.
