· R codes 1-4 show how the various steps of the analysis were run
· Additional methods and additional results contains all supplementary methods and results (i.e. Appendices, Supplementary Tables and Figures, excluding Figs S5-S13, which are shown separately in pdf, see below)
· Fig. S5: results for proximal humeral structural parameters. A-B: DF1-DF2 and DF2-DF3 biplots, with ecological clusters mapped on them.

C-K: boxplots DFs and parameters of interest (identified as detailed in the Main Text), for the eco-clusters which yielded significant differences from pairwise comparisons
· Fig. S8A-N: further boxplots of humeral diaphyseal parameters of interest (identified as detailed in the Main Text), for the eco-clusters which yielded significant differences from pairwise comparisons
