Sauropod limb measurements and body-mass estimates

This dataset is an updated compilation of published sauropod body-size data, expanded from earlier work (d'Emic 2023) to 205 taxa with published mass estimates. It includes published sauropod limb measurements and corresponding body-mass estimates derived using standard phylogenetically corrected allometric relationships that map stylopodial limb dimensions to body mass, as commonly done for extinct quadrupeds.

本数据集为已发表蜥脚类（Sauropoda）体型数据的更新汇编，相较于此前研究（d'Emic 2023），样本量已扩充至205个带有已发表体重估计值的分类单元。本数据集收录了已发表的蜥脚类肢体测量数据，以及通过标准系统发育校正异速生长关系推导得到的对应体重估计值——该关系将肢体近段骨骼尺寸与体重建立关联，这一方法在已灭绝四足动物的相关研究中被广泛采用。
