Supplementary material S1 - Table S1 Specimen numbers, taxonomic authorities, and institutional abbreviations.
Supplementary material S2 Landmark coordinates of all taxa included in the study (.nts format).
Supplementary material S3 - Figures S1-S4 Figure S1, two phylogenies inclusive of fossil taxa that were used in this study; Figure S2, accuracy test of landmarking procedure; Figure S3, distribution of variance of the principal components; Figure S4, distribution of variance for the first 10 phylogenetic principal components derived from both phylogenies adopted (i.e. with Dinilysia as a stem alethinophidian and as a stem ophidian).
Supplementary material S4 - Table S2 Ecology of all the taxa included in the study and literature sources.
Supplementary material S5 Scripts used to run the analyses in R.
Supplementary material S6 - Table S3 First 10 ordinary principal components for all taxa included in the study.
Supplementary material S7 Three-dimensional ordinary PCA plot of PC1 vs PC2 vs PC3. Colour coding is the same as in Figure 2.
Supplementary material S8 – Table S4 First 10 phylogenetic principal components (PPCs) for all taxa included in the study and for both phylogenentic PCA analyses (i.e. with Dinilysia as a stem alethinophidian and as a stem ophidian).
Supplementary material S9 Three-dimensional phylogenetic PCA plot of PC1 vs PC2 vs PC3 (based on phylogeny where Dinilysia is a stem alethinophidian). Colour coding is the same as in Figure 2.
