Supplementary table T3: 29 measurements of body form and the size, shape, and position of eyes and fins taken from fossil specimens of Silurian and Devonian vertebrates using calipers and, in rare cases for large specimens, tailor tape. Categorized by Class. Proportions of each measurement relative to standard length (tip of the rostrum to the caudal peduncle) calculated for each specimen. For taxa with multiple specimens, averages were taken. length or leading edge of structures that were absent were recorded as "0", distances (from the rostrum) and missing measurements (from incomplete specimens) were recorded as "-" or not applicable. proportions of 120 taxa used in associated article for this data were z-transformed. Supplementary file containing additional supplementary tables and figures, with results, are included; as is the r-script and necessary files for calculating Gower's dissimilarity matrix and Principal Coordinate Analysis, as well as correlation coefficients and the coefficient of determination for each variable on the first four axes.
