四川峨眉麦地坪剖面下寒武统麦地坪组上段ｃｈａｎｃｅｌｏｒｉｄｓ类骨片化石丰富，皆以磷质内核方式保存，其中首次发现具有两个中央射管的ｃｈａｎｃｅｌｏｒｉｄｓ骨片。对ＣｈａｎｃｅｌｏｒｉａｉｒｒｅｇｕｌａｒｉｕｓＱｉａｎ，Ｃｈａｎｃｅｌｏｒｉａｓｐ．，Ａｌｏｎｎｉａｓｐ．进行了详细描述。在内核标本表面，骨片的基面上首次发现了保存极好的网状微细构造。对这一微细构造解释尚有困难，但有可能为骨片原始壳体结构的内端印痕。同时，对ｃｈａｎｃｅｌｏｒｉｄｓ化石的归属及分类问题进行了讨论。
In the upper part of the Lower Cambrian Maidiping Formation in the Mabianping section of the Emei, Sichuan Province, there are abundant fossilized brittle fossils, all of which are preserved in the form of a phosphorus core. For the first time, there are two central shotglass chancelorids bones. On Chanceloriairreg ulariusQian, Chanceloriasp. Alonniasp. Described in detail. On the surface of the core specimen, the best preserved fine mesh structure was found for the first time on the basal surface of the bone fragment. There is still some difficulty in interpreting this fine structure, but it is likely to be the inner footprint of the original shell structure of the bone chip. At the same time, the classification and classification of chancelorids fossils are discussed.
