Data S3: EchinoTree_Mode.nex

‘EchinoTree_Mode.nex’ is a NEXUS file containing the anatomical character-state matrix for 40 life-habit characters for 366 Cambrian–Ordovician echinoderm tip genera used in morphological analyses, using the 'mode' life-habit propagation algorithm. 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 (Data S1). Contributed by Phil Novack-Gottshall.
