Finite Element Analysis (FEA) is a powerful tool for functional morphology purposes. The accuracy of the final results depends on the mesh generation and the quality of the mesh. This is especially important in vertebrates as they present a complex biological structure, implying a complex geometry and, consequently, mesh generation should be performed with a consistent criterion. The aim of this paper is to discuss different ways to create a mesh of a vertebrate structure with different mesh generation methods and give recommendations on how to generate an efficient mesh without exceeding computational limits. Topics such as quality of the mesh, suitability of the mesh and reliability of the mesh are introduced to help the generation of the mesh. In this case, the use of convergence procedures assures the results of the computational solution and can be a good solution for the vertebrate models. The skull of a Chinese giant salamander (Andrias davidianus) is used as a case study.
