摘　　要：近期笔者在扬子台地边缘的贵州松桃寒武系清虚洞组灰岩中利用酸解处理获得了丰富且保存较好的磷酸钙质微体化石。对其中的管状骨骼化石似软舌螺类Hyolithelminths进行报道,分别是:似软舌螺属Hyolithellus Billings,1871和小钻孔螺属Torellella Holm,1893。本次发现的管状骨骼化石似软舌螺类是在贵州松桃地区的首次报道,不仅完善了清虚洞组的微体生物面貌,拓展了其在寒武纪第二世的古地理分布范围,也为寒武纪早期骨骼化生物的发育与演化研究提供了新的材料。Recently,abundant and well-preserved calcium phosphate shelly fossils were obtained from limestone of the Tsinghsutung Formation by acid treatment in Songtao,Guizhou,where in the edge of the Yangzi platform.In this paper,tubular skeletal microfossils Hyolithelminths are systematically reported,including of 2 genera of Hyolithelminths:Hyolithellus Billings,1871 and Torellella Holm,1893.The tubular skeletal microfossils discovered herein can not only enrich the small shell fossils assemblages from Tsinghsutung Formation and expand its geographical distribution,but also provide new materials for the study of the origin and evolution of skeletal organisms in the early Cambrian.
