Pairwise differences for microwear attributes of extant ursid lower second molars (Dunn’s procedure).

*Significant values are noted in bold text (P<0.05) and represent analyses performed absent of the Bonferroni correction; Asfc, area-scale fractal complexity; epLsar, anisotropy; Tfv, textural fill volume.具有统计学显著性的数值以粗体标注（P<0.05），且对应的分析未进行邦弗朗尼校正（Bonferroni correction）；Asfc：面积尺度分形复杂度（area-scale fractal complexity）；epLsar：各向异性（anisotropy）；Tfv：纹理填充体积（textural fill volume）。
