This paper reviews recent advances in myriapod phylogenetics and presents a preliminary phylochronologic scheme of the evolutionary events in early my-riapods with the following observations: 1） Myriapoda might have diverged from its sister group during late Cambrian or earlier.

精确的多足动物亚门谱系发生关系以及谱系年代学细节还有待于进一步综合系统学、多基因和多重化石参照点的合理分析加以深入和完善，进而为早期陆地复杂生态系统的建立提供新的证据。

The natural Slates such as Slideproof Slate, Avianize Slate, Mosaic and Cuture Stone, the main products of our company mined from quarries formed through millions of years, are hard in quality and bright in color. Because of their unique layer structures, they have very strong flexural strength. Their wear-resistant and corrosion-resistant properties make them ideal building materials used for both interior and exterior.

主要产品是火烧板、亚光板、马赛克、文化石等天然板岩，开采于经过数亿万年形成的石材矿床，品质坚硬，色泽鲜明，其特殊的层状结果决定了它的抗折强度很高，尤其良好的耐磨、耐腐蚀的天然石材特征，使其成为一种地面、屋面、室内外墙面非常理想的建筑材料。
