Fig. 21. Tukey box plots of the number of vertebrae in species of Spintherobolus. Visual comparison of these box plots shows that the vertebral counts of S. papilliferus are obviously different from all other species. Those of S. broccae and S. leptoura are not significantly different and those of S. ankoseion, although overlapping with those of S. broccae and 5. leptoura are significantly different from these two species when subject to Mann-Whitney rank-sum tests (T = 398, P <0.001 and T = 246, P <0.001 respectively).
