Electronic supporting information for: Evolution of posture in amniotes–diving into the trabecular architecture of the femoral head

# Gônet et al. Evolution of posture in amniotes–Diving into the trabecular architecture of the femoral head. Electronic supporting information. [Access this dataset on Dryad](10.5061/dryad.83bk3j9x2) This dataset contains the information files that support the results presented in the study by Gônet, J., Laurin, M., & Hutchinson, J. R. ## Description of the data and file structure The file entitled Phylogenetic\_Trees.tre contains the 100 phylogenetic trees used in the study. The trees are in Newick (parenthetic) format. The file can be opened and modified as a .txt file, but is intended for use in R as part of the analyses presented in the study. The file entitled Supporting\_Information.pdf contains the supplementary figures and tables mentioned in the main text of the study. The file entitled Bone\_Cubes.rar contains the new microanatomical data obtained to complement the original data from Doube et al. (2011). The archive contains 25 folders corresponding to the 25 amniote species studied for which new microanatomical data are available. These are provided as .tif files. The name of each folder is determined as follows: Genus\_species\_identifier.

## 数据与文件结构说明
名为Phylogenetic_Trees.tre的文件内含本研究使用的100棵系统发育树（phylogenetic trees），这些树以Newick（括号式）格式存储。该文件可作为纯文本（.txt）文件打开并编辑，专为适配本研究分析所用的R语言环境设计。
名为Supporting_Information.pdf的文件包含研究正文中提及的补充图表与附表。
名为Bone_Cubes.rar的压缩包包含新增的显微解剖学数据，用于补充Doube等人（2011年）的原始数据集。该压缩包内含25个文件夹，分别对应本研究中获取了新增显微解剖学数据的25种羊膜动物物种，所有数据以.tif格式文件存储。每个文件夹的命名规则如下：属名_种名_标识符（Genus_species_identifier）。
