Data S2: EchinoTree_Morph.nex

‘EchinoTree_Morph.nex’ is a NEXUS file containing the anatomical character-state matrix for 413 anatomical characters for 366 Cambrian–Ordovician echinoderm tip genera used in morphological analyses. See “Compiling and formatting morphological and ecological data sets” in Methods above for additional details of coding schema. The file excludes the supertree topology, which is imported instead from the ‘cal3trees’ object. Morphological data contributed by Bradley Deline.

‘EchinoTree_Morph.nex’为一份NEXUS文件，内含用于形态学分析的366个寒武纪-奥陶纪棘皮动物终端属的413项解剖学性状状态矩阵。有关编码方案的更多细节，请参见前文方法章节中的“Compiling and formatting morphological and ecological data sets”一文。该文件未包含超树拓扑结构，此类拓扑结构需从‘cal3trees’对象中导入。本形态学数据由Bradley Deline提供。
