以多种方法和分析成果论证台江县革东的凯里组形成于水深９０－２００ｍ，属温暖、透光、水深较大、沉积速率较高的陆棚环境，海底表面处于氧化还原界面附近，该环境较有利于生物繁衍。通过对多门类化石保存特征分析，近似地恢复生物群，划分出４个埋藏相和６个埋藏亚相。凯里动物群的保存条件可归结为：生物原生活于陆棚泥表面或水中，因陆棚水体能量较小，海底表面接近氧化还原界面，内栖生物少，生物扰动及食腐行为很少发生，防止埋藏前的各种破坏作用，死后被陆棚泥快速掩埋、缺氧，经早期成岩作用（如硅酸盐、黄铁矿、钙质充填、矿化和交代），成为完好的化石或软体铸模、印痕。而周期性、短暂水流或事件沉积未带来较粗沉积物而影响化石的保存。这种保存环境与Ｓｐｅｙｅｒ等提出的古生代大陆边缘环境第７埋藏相相似，与布尔吉斯页岩动物群和澄江动物群的保存环境明显不同 A variety of methods and analysis results demonstrate that the Kaili Formation in the eastern part of the Taijiang Formation is formed at a water depth of 90-200m, which is a warm, light-transmissive, deep-water and high deposition rate continental shelf environment with the seabed surface near the redox interface , The environment is more conducive to biological reproduction. Based on the analysis of the conservation features of various fossils, the biota are restored approximately, and four buried facies and six buried subfacies are identified. Kaili fauna can be attributed to the preservation of conditions: the original living in the clay surface or water, due to the small energy of the landfill water, the seafloor surface near the oxidation-reduction interface, fewer benthic organisms, biological disturbance and corrosion behavior is very Occur less frequently, prevent all kinds of destructive effects before burial, and are rapidly burial buried by the mud of the shelf after death, and become an intact after anoxia and early diagenesis (such as silicate, pyrite, calcareous mineralization and mineralization) Fossil or soft mold, imprint. Periodic, transient water or event sedimentation does not result in the coarsening of deposits that affect the conservation of fossils. This preservation environment is similar to the 7th burial of the Paleozoic marginal environment of the Paleozoic proposed by Speyer et al., Which is obviously different from the preservation environment of the Burgess shale and Chengjiang fauna
