Promoting gigantism: Costal ventilation model based on quantitative analysis of the respiratory system in recent and fossil amniotes

在第一个资助期的基础上，我们将利用板龙、梁龙、腕龙和圆顶龙化石椎骨中的肋骨关节点作为个体肋骨运动的平面，扩大和完善蜥脚类动物肋骨通风的矢量计算机模型。外部肋间肌肉组织的方向将从化石肋骨中的Sharpey纤维重建，该方法正在使用鸟类，哺乳动物和“爬行动物”的现存材料进行完善。这些数据将与形态和生理呼吸参数的异速生长估计相融合，并辅以研究单位其他小组在运动，营养和心血管生理学方面的工作结果，以提供蜥脚类动物呼吸系统结构和功能的完整图像。在此基础上，呼吸系统的作用，促进蜥脚类动物的反殖症进行评估。

Based upon groundwork (aid in the first funding period we will amplify and refine the vectorial computer model of costal ventilation in sauropods, using rib articulation points in fossil vertebrae of Plateosaurus, Diplodocus, Brachiosaurus and Camarasaurus as the plane of individual rib movement. The orientation of external intercostal musculature will be reconstructed from Sharpey's fibers in fossil ribs, the methods being perfected using extant material from birds, mammals and "reptiles". These data will be converged with allometric estimates of morphological and physiological respiratory parameters, supplemented by the results of other groups in the Research Unit working on locomotion, nutrition and cardiovascular physiology in order to provide a complete picture of the structure and function of the respiratory system in sauropods. On this basis, the role of the respiratory system in promoting gigantism in sauropods will be evaluated.
