Additional file 2: of On trends and patterns in macroevolution: Williston’s law and the branchiostegal series of extant and extinct osteichthyans

Data and scripts used in the subsampling analyses. This consists of 4 files (a,b,c,d). Data files include the branchiostegal count and stratigraphic information collected for extant and extinct species (bst_analysis.csv, tabular data), and the time-scaled trees (trees.tre, Newick format) used in the analyses. The 2 R script files also included were used for running the jackniffing analyses that subsample extinct (fossil_subsampling_1.R) or extant species (extant_subsampling_1.R). The “species” column in the CSV file contains the species in the tree to which the data were mapped. The “old_label” column contains the names of the taxa as they appeared in our original sources. An anonymous referee kindly noted that our data had an erroneous value of 1 branchiostegal ray for Lepidosiren paradoxa, which does not have any branchiostegals in reality. We did not rerun our analyses because they are very time-consuming, and this small correction is unlikely to have any significant effect. However, we amended the CVS file that we provide here, so that the error does not propagate to any possible future uses of the data by other researchers. (ZIP 162 kb)
