产于安徽淮南下寒武统馒头组上部浅水台地相灰岩和棕褐色页岩中的遗迹化石鉴定为５属５种，包括１新种，它们是Ｂｅａｃｏｎｉｃｈｎｕｓｉｃｈｎｏｓｐ．，Ｄｉｐｌｉｃｈｎｉｔｅｓｉｃｈｎｏｓｐ．，Ｐｈｏｅｂｉｃｈｎｕｓｍｉｎｏｒｉｃｈｎｏｓｐ．ｎｏｖ．，ＴｈａｌａｓｉｎｏｉｄｅｓｈｏｒｉｚｏｎｔａｌｉｓＭｙｒｏｗ，１９９５和Ｈｅｌｍｉｎｔｈｏｉｄａｉｎｄｅｔ．ｉｃｈｎｏｓｐ．。对它们的形成方式研究推测Ｂｅａｃｏｎｉｃｈｎｕｓｉｃｈｎｏｓｐ．和Ｄｉｐｌｉｃｈｎｉｔｅｓｉｃｈｎｏｓｐ．是三叶虫的爬行迹，Ｐｈｅｏｂｉｃｈｎｕｓｍｉｎｏｒｉｃｈｎｏｓｐ．ｎｏｖ．是蠕虫类的逃逸迹，Ｔｈａｌａｓｉｎｏｉｄｅｓｈｏｒｉｚｏｎｔａｌｉｓ是蠕虫类的栖居迹，Ｈｅｌｍｉｎｔｈｏｉｄａｉｎｄｅｔ．ｉｃｈｎｏｓｐ．是腹足类的移动迹，它们都形成于含盐、含氧量正常的非深海环境。Ｂｅａｃｏｎｉｃｈｎｕｓｉｃｈｎｏｓｐ．和Ｄｉｐｌｉｃｈｎｉｔｅｓｉｃｈｎｏｓｐ指示Ｃｒｕｚｉａｎａ遗迹相；Ｐｈｅｏｂｉｃｈｎｕｓｍｉｎｏｒｉｃｈｎｏｓｐ．ｎｏｖ．和Ｔｈａｌａｓｉｎｏｉｄｅｓｈｏｒｉｚｏｎｔａｌｉｓ指示Ｇｌｏｓｏｆｕｎｇｉｔｅｓ遗迹相；Ｈｅｌｍｉｎｔ?
The trace fossils in limestone and tan shale of the Upper Shallow Platform of the Lower Cambrian Mantou Formation in Huainan, Anhui Province are identified as 5 genera and 5 species, including 1 new species, which are Beaconichnusichnosp. , Diplichnitesichnosp. , Phoebichnusmi norichnosp. nov ThalasinoideshitudinalisMyrow, 1995 and Helminthoidaindet. ichnosp. . The formation of their study speculated Beaconichnusichnosp. And Diplichnitesichnosp. Trilobite crawling trace, Pheo bichnusminorichnosp. nov Is a worm escape, Thalasinoideshorizontalis is a habitat of helminths, Helminthoidaindet. ichnosp. It is a moving trace of gastropods, all of them formed in a non-deep-sea environment containing salt and oxygen. Beaconichnusichnosp. And Diplichnitesichnosp indicate Cruziana relics; Pheobichnusminorich-nosp. nov And the Thalasinoideshorizontalis indicate the remains of the Glosofungites; Helmint?
