Results of pairwise comparisons (after [102]) following a Kruskal-Wallis test on samples of scratch breadth.

Results in bold indicate cases where the null hypothesis (distributions in each sample are the same) cannot be rejected. Putative high browsers (Brachiosaurus and Camarasaurus) cannot be distinguished based on scratch breadth. Dicraeosaurus is distinguishable from all others. Diplodocus and Nigersaurus cannot be distinguished.
