项目摘要
The pelvis is of great functional importance in tetrapods in supporting a large part of the body weight, providing a rigid connection between the hindlimbs and the vertebral column, and providing insertion areas for important limb muscles. Three pelvic types are distinguished in dinosaurs, referring to a cranial (propubic), ventral (mesopubic), or caudal (opisthopubic) orientation of the pubis. The development of these different pelvic shapes from dinosauromorphs to dinosaurs could never be satisfyingly explained. Pelvis shapes in dinosauromorphs and basal dinosaurs will therefore be analyzed by the innovative technique of Finite Element Structure Synthesis (FESS), which allows precise identification of shape-forming mechanical influences on the pelvis. Thereby, different hypotheses about soft-tissue reconstructions and the distribution of mechanical stresses acting on the pelvis during rest, locomotion, and ventilation, can be tested. Extant crocodylians and birds will provide the basis for comparisons in an Extant Phylogenetic Bracket approach, and will be used for a validation of the novel technique of FESS prior to the analysis of dinosaurian pelves. The results will be discussed under the aspects of evolutionary history and functional morphology. This integrative approach will help to better understand the consequences of the development of different pelvis shapes in dinosaurs for their locomotion and ecology.
骨盆在四足动物中具有重要的功能,它支撑大部分体重,在后肢和脊柱之间提供刚性连接,并为重要的肢体肌肉提供插入区域。在恐龙中有三种骨盆类型,分别是指耻骨的头侧(前耻骨)、腹侧(中耻骨)或尾侧(后耻骨)。这些不同的骨盆形状的发展,从恐龙到恐龙,永远无法令人满意地解释。因此,将通过有限元结构合成(FESS)的创新技术来分析脊椎动物和基底恐龙的骨盆形状,该技术可以精确识别对骨盆的形状形成机械影响。因此,不同的假设软组织重建和分布的机械应力作用在骨盆在休息,运动和通风,可以进行测试。现存的鳄鱼和鸟类将提供比较的基础上,在现存的系统发育分析方法,并将用于验证的新技术FESS之前,分析的阿留申骨盆。本文将从进化史和功能形态学两个方面对结果进行讨论。这种综合方法将有助于更好地理解恐龙不同骨盆形状的发展对它们的运动和生态的影响。
