摘要
本文作者在寿山沟组命名剖面系统地采集了 38 个样品,其中 28 个样品中发现了牙形刺,主要有 Mesogondolella idahoensis , M.lamberi , M.siciliensis , Sweetognathus expansus , Sweetognathus sp. ,这一动物群清楚地证明寿山沟组的时代为早二叠世空谷期( Kungurian )最晚期的,仍没进入中二叠世。属特提斯牙形刺省,但海水温度可能稍低些。 Monodiexodina 的时代始于 Kungurian 期的最晚期。
Thirty-eight samples have systematically collected from the Shoushangou Formation in central Jilin Province, in which 28 samples yields conodonts, including mainly Mesogondolella idahoensis, M. larnberti, M. siciliensis, Sweetognathus expansus, Sweetognathus sp. This conodont fauna clearly indicatets that the age of the Shoushangou Formation should be assigned to the latest Kungurian. Biogeographically, this fauna should be belong to Tethyan conodont Province（TP）（= Ouchita-Cathaysia conodont Province（OCP）, but the temperature of water could be a little lower than normal TP （=OCP）water. The range of fusulinid Monodiexodina is from the latest Kungurian to Wordian.
