| 摘 要： | 据称“在甘肃省红柳园地区的泥盆纪地层中发现过一块保存不完整的腕足类 ?Stringocephalus标本”,因此有人主张将该区的泥盆系归属于所谓的“南型”海相泥盆系。但不论是从该区泥盆纪地层的发育特征、岩相建造、火山活动、沉积厚度 ,还是从古生物的组合面貌来看 ,红柳园地区的泥盆系与所谓的“北型”海相泥盆系却十分相似 ,而与“南型”海相泥盆系则差别甚大。最近该化石的原鉴定者面告 ,当初对那块化石的鉴定有误 ,可能是一种腹足类 ,红柳园地区不存在 Stringocephalus。因此 ,将甘肃省红柳园地区的泥盆系归属于“南型”海相泥盆系的主张是值得商榷的

| Abstract: | Due to the discovery of one piece of badly preserved brachiopod ?Stringocephalus, some geologists considered that the Devonian of the Hongliuyuan area belongs to the “South type” marine Devonian. However, the recent study of this original specimen shows that it is a gastropod and not a brachiopod. Moreover, the stratigraphical formation, facies development, volcanic activity, deposit thickness and palaeontological assemblages of the Devonian of the Hongliuyuan area are very similar to the “North type” marine Devonian. |
