摘要
在孤峰组底部发现了包括Ｍｅｓｏｇｏｎｄｏｌｅｌｌａｎａｎｋｉｎｇｅｎｓｉｓ在内的牙形刺动物群。ＧｏｎｄｏｌｅｌｌａｓｅｒｒａｔａＣｌａｒｋｅｔＥｔｈｉｎｇｔｏｎ，１９６２是Ｍｅｓｏｇｏｎｄｏｌｅｌｌａｎａｎｋｉｎｇｅｎｓｉｓ（Ｊｉｎ，１９６０）的同义名。Ｍｅｓｏｇｏｎｄｏｌｅｌｌａｎａｎｋｉｎｇｅｎｓｉｓ已被北美学者推荐为瓜达洛坪统底界的标志化石。因Ｍｅｓｏｇｏｎｄｏｌｅｌｌａｎａｎｋｉｎｇｅｎｓｉｓ的正模（Ｈｏｌｏｔｙｐｅ）已丢失，本文重新选定了模式标本（Ｎｅｏｔｙｐｅ）。
A conodont fauna, including Mesogondolella nankingensis, has been found in the lowest part of the Kufeng Formation. Gondolella serrata Clark et Ethington 1962 is treated as a synonym of Mesogondolella nankingensis (Jin, 1960). The lower limit of the Guadalupian Series is defined at the first occurrence of Mesogondolella nankingensis (Jin, 1960).
