贵州化石丰富,素有古生物王国之称,其中早期特异埋藏后生生物十分发育,由老至新有埃迪卡拉系的瓮安生物群、江口庙河生物群,寒武系第1统的小壳动物群、第2统下部的牛蹄塘生物群及中上部的杷榔动物群、第3统底部的凯里生物群。这些特异埋藏生物群与云南寒武系的澄江动物群、关山生物群及陕南埃迪卡拉系高家山生物群构成了我国早期后生生物的演化链,反映了从动物起源(瓮安生物群)、可疑多门类动物出现(江口庙河生物群)、动物骨骼化(高家山生物群)、生物矿化质和量的变化或骨骼动物爆发性辐射(小壳动物群)及海绵动物辐射(牛蹄塘生物群)再到动物主要门类出现的寒武纪大爆发(澄江动物群)、海洋生物多样化及生态复杂化(凯里生物群)的演化过程。
Guizhou is rich in fossils, known as the kingdom of paleontology, of which early specific buried epigenetic organisms are well developed, from the old to the new Ediacaran Weng’an biota, Jiangkou Miaohe biota, Fauna, the lower part of the second system of the Niutizu biological community and the upper part of the berea animal group, the bottom of the third system of the Kaili biota. These specific burial biota and the Chengjiang fauna, Guanshan biota in the Cambrian and the Gaojiashan biota in southern Shaanxi constitute the evolutionary chain of the early metazoan in China, reflecting the evolution from animal origin (Weng’an biota) (Jiangkou Miaohe Biota), animal skeletal (Gaogushan biota), changes in biochemical mineralogical and quantitative or skeletal animal burst radiation (small shell fauna) and sponge animal radiation The Tuotang Biota) to the major Cambrian catastrophe (Chengjiang fauna), the evolution of marine biodiversity and the ecological complex (the Kaili Biota) that occur in the major animal species.
