Post-hoc tests are one-tailed Mann–Whitney U-tests of the null hypothesis that the more cursorial taxon displays greater long bone bending strength. Table formatting and abbreviations follow Table 4.
**
Because the overall Krukal–Wallis test comparing tibial bending strength index among species was not significant, post hoc comparisons were not carried out.
