笔者中江、肖二人1971年赴保山作地质调查,在保山羊邑褐煤矿开采场,于煤层顶板采获一脊棱齿象化石的部份骨骼。此一脊棱齿象与云博1975年报导的保山剑齿象(Ste- godon baoshanensis)、类象剑齿象(Stegodon elephantoides)同出一层位。对这一脊棱齿象的发现和描述,增添了脊棱齿象的新材料,扩大了脊棱齿象的地理分布范围,为研究剑齿象类的起源和演化,提供了素材;同时进一步证实羊邑地区褐煤的生成时代为晚第三纪上新世,也为该煤系的划分与对比提供了化石依据。 The author Zhong Jiang and Xiao Er went to Baoshan for geological survey in 1971 and took part of the bones of a ridge-shaped fossil in the coal seam roof at the brown coal mine in Baoshan Yang Yi. This ridges is similar to the Ste- godon baoshanensis reported in Yunbo in 1975 and resembled Stegodon elephantoides. The discovery and description of this ridges and odontology added new materials of ridges and teeth and expanded the geographical distribution of ridges and teeth, which provided the material for the study of the origin and evolution of saber-toothed images. At the same time, Confirmed that the generation of lignite in Yangyi area was late in the late Tertiary and provided fossil basis for the division and contrast of the coal series.
