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.

加粗标记的结果对应无法拒绝原假设（各样本的分布均相同）的情形。基于刮痕宽度（scratch breadth），推定的高位取食类群（high browsers）——腕龙（Brachiosaurus）与圆顶龙（Camarasaurus）无法被区分。叉龙（Dicraeosaurus）可与其余所有类群相区分。梁龙（Diplodocus）与尼日尔龙（Nigersaurus）无法被区分。
