Abstract: Deciphering the relationship between the morphology and function of palaeontology is an important part of the reconstruction of palaeontological lifestyle, which is of great significance for the determination of palaeontological evolution process, taxonomic position and paleoenvironmental information. However, palaeontological groups often lack quantitative data about some behavioral function, and it is difficult to find living organisms which are similar to the study objects. That has become the biggest obstacle for their morphological function analysis at present. Computational fluid dynamics (CFD), a tool for generating quantitative data based on numerical simulations of fluids and solid, has been able to easily solve any two-dimensional and most three-dimensional flow fields, including paleomorphological functional simulation and analysis. In this paper, the history of biological morphological function and the brief the basic principle of CFD were carried on, the general flow of functional analysis of CFD in paleontology and the application of CFD in paleontology form function analysis were summarized. CFD has great potential in sovling the argumentation of long-standing paleontology function and ecology hypothesis. Finally, the application of CFD in paleontology foreground was prospected. CFD created a new research direction for fossil biological form function correlation analysis and performance test. In the future, CFD should become an important method and powerful tool for paleontologists to find out the problems related to fossil functional biology.
