| 摘 要： | 吉林省四平南部1:5万半拉山门、石岭街、下二台子、叶赫站幅的吉林省境内区调,首次在经过修订的下二台群黄顶子组下部条带状硅质大理岩中,采获丰富的小壳化石,初步确定为3属6种,其中4新种。属于辽北地区新确立的清河镇动物群辐射演化而来的新的动物群。从而,为这套地层的划分对片、时代确定,提供了重要的古生物佐证。

| Abstract: | During the regional geological investigation of 1:50000 in the south of Siping,abundant small shelly fossils were collected in strip banded silicon marbles which belong to Huangdingzi formation of Xiaertai group revised . The fossls were appraised by research fellow------Liu Xiaoliang from Shenyang Geological Institute. They are composed of six species in three genera, with four of them are new. They belong to a newly established fauna,Changtu Fauna, which derived from the radiant evolution of Qinghezhen Fauna. The discovery of these fossils are significant in age determination and strata dividing of Xiaertai Group.The features of the small shelly fossils together with its hosting strta were described and explained in detail in this paper. According to the idea of the appaising person and the synthetical data of some radilisotope age report of this region,the age of Xiaertai Group should be Ordovician. |
