古生物和地质学都是地质科学的基础学科,对地质科学的发展关系重要。广义的地层学是研究成层岩石的相互关系及其时、空的分布规律的科学,主要内容包括地层的层序和时代及地理分布,地层分类、对比以及各种岩层之间的相互关系等。而古生物学则正是根据保存在地层中的各类化石,研究地史时期生物的形态、构造、分类、分布以及演化关系
Palaeontology and geology are both basic disciplines of geosciences and are important for the development of geosciences. The generalized stratigraphy is a science to study the relationship between the stratigraphic rocks and their temporal and spatial distribution. The main contents include stratigraphic sequence, age and geographical distribution, stratigraphic classification, contrast, and the relationships among strata . Paleontology, on the other hand, is based on various types of fossils preserved in strata to study the morphological, structural, taxonomic, distribution and evolutionary relationships of geo-
