贵州省福泉桅杆坪地区寒武系底部牛蹄塘组黑色页岩中以炭质印模的形式保存有大量宏观后生动物化石.化石微细特征保存较差,多属于疑难化石.该化石组合以化石个体较大的蠕虫状化石和疑似杆壁虫类化石为优势分子,还常见管状类化石、遗迹化石,以及少量的软舌螺、海绵骨针等化石碎片.该化石组合紧位于镍钼多金属层之上,与遵义等地区的松林生物群(牛蹄塘组下生物群)的层位相当,化石组成基本一致,但优势生物存在明显差异.福泉地区牛蹄塘组蠕虫状化石组合的发现,丰富了寒武系牛蹄塘组的生物群面貌,为研究早期后生动物演化提供了新资料和新信息.对该化石组合的进一步研究,也必将为这种特殊生物群的古环境恢复和埋藏学研究提供有利的古生物学证据.
A large number of macroscopical metazoan fossils are preserved in the black shale in the Niutitang Formation at the bottom of the Cambrian at the Maupinping area, Fuquan, Guizhou Province. The fossil fine features are poorly preserved and mostly belong to the difficult fossils. The fossil assemblage is composed of fossils Larger individual worm-shaped fossils and suspected wall-wall fossils are the dominant molecules, but also common tubular fossils, trace fossils, as well as a small amount of fossil fragments such as soft lingual snails, sponge spicules, etc. The fossil assemblages are closely linked to nickel-molybdenum polymetallic Above the strata, the fossil assemblages are similar to those in the Songlin biota (Niutizi Formation) of Zunyi, but there are significant differences in dominant organisms. The discovery of the worm-shaped fossil assemblage in the Niutitang Formation in Fuquan area Enriched the biotopes of the Cambrian Niutitang Formation and provided new information and new information for the study of the evolution of early metazoans.Further studies on this fossil assemblage will also provide evidence for the paleoenvironment restoration of this special biota And buried studies provide favorable paleontological evidence.
