前言除研究后生动物外,前寒武纪古生物学的研究范围主要有两个方面。一是详细研究燧石中保存的微有机物,其次是研究迭层石,以及迭层石在古生物学和生物地层学上的应用。少数研究者探讨了迭层石纹层中的微化石和迭层石本身的关系。一个主要问题是大部分迭层石是作为含少量与堆积层相一致的微有机物的碳酸盐保存下来的(见格伯林1974,关于主要兰绿藻群中微构造的一次有意义的讨论)。迭层石纹层内保存的细胞残余物的许多令人相信的证据,出现在德兰士瓦白云岩(麦格雷戈等,1974;纳吉,1974)、冈弗林含铁建造[巴洪和泰勒,1965;克劳德,1965;里卡利(Licari)
Preface In addition to the study of metazoans, Precambrian paleontology has two main areas of research. One is to study in detail the micro-organics preserved in chert, followed by the study of the application of laminated stone and of laminated stone in palaeontology and biostratigraphy. A few researchers have explored the relationship between microfossils and layers in the lamellar layers. A major problem is that most of the laminated rocks are preserved as carbonate with a small amount of micro-organic material consistent with the build-up (see Gebeleim 1974, Meaning discussion). Much convincing evidence for the cellular remnants preserved in laminated stratum occur in the Transvaal Dolomites (McGregor et al., 1974; Najib, 1974) And Taylor, 1965; Claude, 1965; Licari
