Theropod dinosaurs were one of the most conspicuous groups of terrestrial vertebrates during the Mesozoic, and, in the form of birds, this is true even today. Although their evolutionary history is thus of greatest importance for understanding the origin and evolution of one of the most diverse vertebrate groups today, studies of macroevolutionary patterns in theropods are still rare, especially for the evolution of the skull in this group. However, recent works on theropod skull ontogeny and biomechanics provide a good base for such studies. In the current project, we will investigate the evolution of the skull in non-avian theropods and basal birds, using a geometric morphometric approach. We will thus establish the morphospace occupied by theropod skulls and analyse shifts in morphospace during theropod evolution. By integrating these morphometric studies with results from analyses of theropod skull ontogeny and biomechanics, we will further investigate the influence of heterochrony and functional aspects on the evolution of the theropod skull. The project will thus lead to a much better understanding of macroevolutionary patterns in the evolution of theropod skulls on the lineage towards birds.

兽脚类恐龙是中生代期间最明显的陆地脊椎动物组之一，即使在今天，这也是如此。尽管它们的进化史对于理解当今最多样化的脊椎动物群体之一的起源和演变至关重要，但对兽脚类动物的宏观进化模式的研究仍然很少见，尤其是对于该组颅骨的演变。然而，最近关于治疗头骨个体发育和生物力学的著作为此类研究提供了良好的基础。在当前的项目中，我们将使用几何形态学方法研究颅骨在非avian兽脚类和基底鸟类中的演变。因此，我们将建立兽脚架头骨所占据的形态空间，并分析脊椎动物进化过程中形态学的变化。通过将这些形态计量研究与兽脚架颅骨个体发育和生物力学分析的结果相结合，我们将进一步研究异缘和功能方面对脊脚架颅骨进化的影响。因此，该项目将导致对鸟类颅骨朝向鸟类的进化的宏观进化模式有更好的了解。
