In this paper , the authors mainly introduce the essential process of 3D-reconstruction, including how to get valuable data from a fossil image, to work out the draft, to prepare the relevant model with external details, and finally to create an artistic and scientific animation. In comparison, most of fossil reconstructions seen from previous publications are 2-dimensional, while the 3D-reconstruction completed by following the method introduced here can easily be converted into a 2D-reconstruction.Moreover,it could also be used for computer graphic animations and entertainment games, including some based on fossils.
