DATA & FILE OVERVIEW

- File List: 

Appendix S1.docx: a general overview of all supplementary materials and methods included in the manuscript.

tree.txt: phylogenetic tree in Newick format.

Table S1.csv: list of used specimens with ID code, sex and museum location. F = female, M = male, U = unknown.

Table S2.csv: anatomical definition of sampled landmarks on each specimen.

Fig. S1.tif: landmark configuration (blue) and semilandmark patch (yellow) used in the analysis. 

Fig. S2.tif: the process of retrodeformation on Barbourofelis fricki. A-B, the specimen before and after the retrodeformation process. C, the original specimen showing the modified areas during the retrodeformation in terms of expansion (blue) and contraction (red).

Fig. S3.tif: the process of retrodeformation on Homotherium serum. A-B, the specimen before and after the retrodeformation process. C, the original specimen showing the modified areas during the retrodeformation in terms of expansion (blue) and contraction (red).

Fig. S4.tif: illustration of the workflow followed to perform conv.map. A. We first performed a Principal Component Analysis on the sample. B. We used the search.conv function (‘RRphylo’ R package) to identify convergent species. C. We performed a Relative Warp Analyses on the shape data, setting the alpha parameter to 1. The RW scores obtained by RWA were fed to conv.map to select the axes best-embodying convergence, by using the ede function (‘inflection’ R package). After the RW axes were selected, their scores were used to compute pairwise angle distances between species. D. conv.map plots highlighting the areas responsible for convergence (in blue).

Fig. 1.html: visualization of the pairwise comparison between Barbourofelis, Homotherium, Smilodon, Thylacosmilus. The Consensus configuration was included in the comparisons. The colour gradient indicates area differences between the two surfaces. Blue indicates no differences (scale bar rescaled into the range 0 – 1). In each case, differences between the two taxa are displayed on a reconstruction of the taxon named on the left.

Fig. 2.html: visualization of the pairwise comparison between Barbourofelis, machairodont cats (Homotherium plus Smilodon), Thylacosmilus. The Consensus configuration was included in the comparison. The colour gradient indicates area differences between the two surfaces. Blue indicates no differences (scale bar rescaled into the range 0 – 1). In each case, differences between the two taxa are displayed on a reconstruction of the taxon named on the left.

data.RDA: data used in the manuscript, any relevant information can be found in the script file.

script.R: script to perform the analyses with the R Cran software.
