贵州寒武纪黔东世杷榔组腕足动物由3属3种组成,其中含2新种,均属舌形贝亚门,包括舌形贝类的Lingulellotreta malongensis(Rong,1974)、博茨傅徒贝类的Diandongia circularis sp.nov.和隐孔贝类的Askepasma transversalis sp.nov.。化石产自黔东地区凯里市、剑河交榜、台江革一等地杷榔组中Arthricocephalus chauveaui-Changaspis elongata三叶虫组合带。杷榔组腕足动物组合与云南黑林铺组和乌龙箐组腕足动物组合较为相似,均含有舌形贝类、博茨傅徒贝类和神父贝类的代表。起源于早寒武世筇竹寺期的Lingulellotreta malong-ensis不仅延伸进入了沧浪铺期,还出现在较深水的陆棚斜坡环境,其演化在区域和时代分布上具有一定的继承性。杷榔组Diandongia circularis sp.nov.的发现是云南早寒武世Diandongia腕足动物辐射演化适应更宽环境的结果。Askepasma Laurie,1986仅见于澳大利亚中部Amadeus盆地Todd河早寒武世白云岩中,杷榔组该属化石的发现,可扩展其地理分布,增加该属动物分类学的新信息。
Brachiopods from the three genera of Burkina Faso, Guizhou Province, are composed of 3 genera and 3 species. Among them, 2 species are Brachiaria, including Lingulellotreta malongensis (Rong, 1974) Diandongia circularis sp.nov. And Askepasma transversalis sp. Nov. Fossils from the eastern part of Kaili City, Jianshui pay table, such as the first group of Taiwan River leather bark nut group Arthricocephalus chauveaui-Changaspis elongata trilobite combination zone. Brachiar species of Brachiat group were more similar to Brachiopods of Heilupeipu group and Wulongwan group in Yunnan, all of them contained representatives of tongue shellfish, Bertz shellfish and primate shellfish. Lingulellotreta malong-ensis, which originated in the Early Cambrian Qiongzhusi period, not only extends into Canglang period, but also appears in the deep-water shelf slope environment. Its evolution has certain inheritance in the regional and epoch distribution. The discovery of the Diandongia circularis sp. Nov. From the group of loquat fruits is the result of the evolution of the brachiopod evolution in Diandongia brachiopods to a wider environment in Yunnan. Askepasma Laurie, 1986, found only in the Precambrian dolomites of the Todd River in the Amadeus Basin, central Australia. The discovery of this fossil from the group of loquat can extend its geographical distribution and add new information on the taxonomy of this genus.
