The principal component analysis was carried out on the tree variables (Nfs, number of fine scratches; Nws, number of wide scratches; Nlp, number of large pits). Dietary categories are based on the extant MUROIDEA database28. Cross-hair lines represent s.d. of the samples considered here, and coloured ellipses the s.d. of the three main ecological groups of the database. ADF, animal-dominated feeders; FDF, fruit-dominated feeders; GDF, grass-dominated feeders; †, extinct species; Cuc, Cucalón (Spain); Dal, Dalhem (Belgium); MBB, Masia del Barbo (Spain); Mur, Murcia (Spain).
