古生代珊瑚研究与理论古生物学有关问题

本文首先介绍了理论古生物学的几个主要方面，包括：演化程式方面的种系渐变论，间断平衡论和间断渐变论，宏演化演化，新灾变论和均一论；分类学方面的分支系统学，进化系统学和数值分类学；生物古地理学方面的扩散模式和隔离分化模式；还有生物结晶学和生物矿物学，然后简要回顾了珊瑚的研究历史，讨论了古生代珊瑚骨骼形成的基本形式，骨骼结构的基本单元和组合方式，系统分类与演化阶段及全球生物古地理，最后提出了古生物学研究

STUDY OF PALEOZOIC CORALS AND SOME ASPECTS OF PALEOBIOLOGY

The present paper contains three parts. The first part is a brief introduction to some important aspects of paleobiology. These are: phyletic gradualism,punctuated equilibrium and punctuated gradualism, macroevolution and microevolution, neocatastrophism and uniformitarianism in the respect of evolutionary pattern,;cladistics, evolutionary systematics and numerical taxonomy in the respect of spstematics; dispersal model and vicariance model of paleobiogeography. Some notes are also given to biocrystallography and biomineralogy. The second part deals mainly with Paleozoic corals. A brief historical review of coral studies is followed by a discussion on the fundamental elements of the skeletons,structural patterm of skeleton,classification, evolutionary stages and world biogeography of Paleozoic corals.The third part denotese two important aspects deserving of more attention in furture research of paleontology in general. The first is referred to new ideas and concepts. Especially emphasized are the idea of mobilism in regard to global tectonics and development by stages in regard to crustal evolution.The second is the application of new research techniques and methods.
