Abstract:
Many fossils of Lagerst?tte is found from the Kuanchuanpu Formation of lower Cambrian in Zhangjiagou section，Xixiang，Shaanxi Province．The precious three-dimensionally phosphatized specimens have important research meaning for the origin and evolution of early life． And it is the basis for biostratigraphic comparison at the pre-trilobites-era of early Cambrian． This paper mainly describes Lagerst?tte and soft-bodied Olivooides multisulcatus Qian，1977．This type of fossil was first reported in Kuanchuanpu Biota in Ningqiang，Shaanxi in 1977， which is the same type as fossils described in this article but from different places，thus it has important research meaning to the stratigraphic correlation．According to new discoveries in Xixiang Biota，this paper compares and adds the characteristics and intraspecific variation of Olivooides multisulcatusQian，1977．
