摘　　要：采集内蒙古大兴安岭中部哈达陶勒盖组中叶肢介化石2属4种,鲎虫化石1属1种,昆虫化石1属1种,其中Euestheria jingynanensis和E.cf haifanggouensis,已认定其时代为中侏罗世,鲎虫Triopssp和昆虫盖翅,时代也为中侏罗世,三类化石共生,因此完全有根据认定哈达陶勒盖组的时代为中侏罗世。2 genera and 4 species, 1 genus and 1 species of Limulus amebocyte fossils, 1 genus and 1 species of insect fossils were collected from the middle part of the Hada Tolgoi formation in the central Daxinganling Mountains, Inner Mongolia, in which Euestheria jingynanensis and E.cf haifanggouensis, have been identified as middle Jurassic. Tachypleus ameboid Triops sp and insect wing-covered age are also middle Jurassic, three kinds of fossil symbiosis, so it is believed that the age of Hada Tolgoi formation is middle Jurassic.
